I bought $1k of the Top 10 Cryptos on January 1st, 2018 (Sept Update)

I bought $1k of the Top 10 Cryptos on January 1st, 2018 (Sept Update)
EXPERIMENT - Tracking Top 10 Cryptos of 2018 - Month 33 - Down -76%
See the full blog post with all the tables here.
tl;dr
  • First one to find the three hidden cultural references gets some moons.
  • What's this all about? I purchased $100 of each of Top Ten Cryptos in Jan. 2018, haven't sold or traded. Did the same in 2019 and 2020. Learn more about the history and rules of the Experiments here.
  • September - BTC, although -8%, outperforms the field this month.
  • Overall since Jan. 2018 - Bitcoin miles ahead of the pack, and only one close-ish to break even point.
  • Combining all three three years, Top Ten cryptos underperforming S&P if I'd taken a similar approach.

Month Thirty Three – Down 76%

2018 Top Ten Summary for September
After a rough start to September, crypto spent the month trying in vain to claw back ground. While a few coins rebounded quite a bit from the monthly lows, most ended up finishing the month significantly down. Out of the 2018 Top Ten group, Bitcoin lost the least, down -8% in September. NEM followed it’s winning August (yes, you read that right) with the poorest performance, down -26%.

Question of the month:

Which cryptocurrency exchange won approval to create America’s first crypto bank in September?

A) Binance B) Binance.us C) Kraken D) Coinbase
Scroll down for the answer.

Ranking and September Winners and Losers

Rank of 2018 Portfolio - 50% no longer in Top Ten
A lot of shuffling in September. On the upside, Bitcoin Cash and Cardano gained one place each landing at #5 and #10 respectively. Cardano gets special mention for re-entering the Top Ten.
Heading the wrong direction were IOTA, NEM, Dash, and Stellar each falling two or three spots.
The big story though, for long time crypto watchers, was the ejection of Litecoin from the Top Ten, down five places from #7 to #12 in just one month. For some context, Litecoin’s absence from the Top Ten is a Top Ten Experiment first. It is also the first time since CoinMarketCap has tracked crypto rankings that Litecoin has not been in the Top Ten.
Drop outs: After thirty-three months of this experiment 50% of the cryptos that started 2018 in the Top Ten have dropped out. NEM, Litecoin, Dash, IOTA, and Stellar have been replaced by Binance Coin, Tether, BSV, LINK, and most recently, DOT.
September Winners – Although it lost -8% of its value, this month’s W goes to Bitcoin. ADA gets second place, down -15% and climbing back into the Top Ten.
September Losers – As most probably expected after an extremely out of character victory last month, NEM came back down to earth in September, bigly, down -26%. Litecoin finished right behind, down -24% and dropping out of the Top Ten.
For the overly competitive, below is a tally of the winners of the first 33 months of the 2018 Top Ten Crypto Index Fund Experiment. Bitcoin still has the most monthly wins (8) and Cardano in second place with 6 monthly wins. With its poor September performance, NEM now has 7 monthly losses.
Ws and Ls - One clear winner
Every crypto has at least one monthly win and Bitcoin is unique as the only cryptocurrency that hasn’t lost a month yet since January 2018.

Overall update – BTC solidly in the lead, followed by ETH. Dash in the basement, LTC drops out of the Top Ten.

Even though BTC took a bit of a detour on its way back to break-even point, it is still far ahead of the field, down -17% since January 2018. The initial investment of $100 thirty-three months ago is now worth about $83. Second place Ethereum is down -49% over the same time period.
At this point in the 2018 Top Ten Experiment, Dash is at the bottom. It is currently worth $70.49, down from a January 1st, 2018 starting price of over $1,000. That’s a loss of -93%. The initial $100 invested in Dash 33 months ago is now worth $6.77.
The big story this month is LTC’s departure from the Top Ten, the first time since I started the experiment back in January 2018. Whether or not it will eventually fend off the new generation of coins remains to be seen, but it certainly is noteworthy to have one of the most well known and long standing cryptos drop out of the Top Ten. Consider pouring one out for Litecoin.

Total Market Cap for the entire cryptocurrency sector:

The crypto market lost over $35B in September and is down -39% since January 2018. The value of the overall crypto market is near where it was in August of this year, just a few months back. As painful as the beginning of the month was, looking at a table like this helps with perspective, especially if you’re panic prone.

Bitcoin dominance:

After steadily dipping for months, BitDom increased a bit in September, up to 57.5%.
For some context: since the beginning of the experiment, the range of Bitcoin dominance has been quite wide: we saw a high of 70% BitDom in September 2019 and a low of 33% BitDom in February 2018.

Overall return on $1,000 investment since January 1st, 2018:

The 2018 Top Ten Portfolio lost -$50 this month. If I cashed out today, the $1000 initial investment would return about $238, down -76% from January 2018.
September broke an encouraging upward trend, but at least the portfolio is taking a break from the -80% range. Here’s a look at the ROI over the life of the experiment, month by month, for some context:
33 Monthly ROIs on Top Ten since Jan 2018
The absolute bottom was -88% back in January 2019.
So the Top Ten Cryptos of 2018 are down -76%. What about the 2019 and 2020 Top Tens? Let’s take a look:
So overall? Taking the three portfolios together, here’s the bottom bottom bottom line:
After a $3000 investment in the 2018, 2019, and 2020 Top Ten Cryptocurrencies, my combined portfolios are worth $‭3,340‬ ($238+ $1,538 +$1,564).
That’s up about +11% for the three combined portfolios, compared to +31% last month.
Here’s a table to help visualize:
Combined ROI on $3k over 3 years - UP +11%
That’s a +11% gain by investing $1k on whichever cryptos happened to be in the Top Ten on January 1st for three straight years.
But surely you’d do better if you went all in on one crypto, right?
Depends on your choice. Let’s take a look:

ETH for the win
Only five cryptos have started in the Top Ten for all three years: BTC, ETH, XRP, BCH, and LTC (unless Litecoin can make a comeback by the 1st of Jan. 2021, it’s not going to make the four year club!). Knowing what we know now, which one would have been best to go all in on?
Ethereum, by a pretty good margin: the initial $3k would be up +104%, worth $6,118 today. The worst choice of a basket to put all your eggs in at this point in the experiment is XRP, down by almost one third.

Comparison to S&P 500:

I’m also tracking the S&P 500 as part of the experiment to have a comparison point with other popular investments options. The S&P 500 Index fell from an all time high in August, but is currently up +26% since January 2018.
S&P since Jan. 2018
The initial $1k investment into crypto on January 1st, 2018 would have been worth about $1260 had it been redirected to the S&P.
But what if I took the same invest-$1,000-on-January-1st-of-each-year approach with the S&P 500 that I’ve been documenting through the Top Ten Crypto Experiments? Here are the numbers:
  • $1000 investment in S&P 500 on January 1st, 2018 = $1260 today
  • $1000 investment in S&P 500 on January 1st, 2019 = $1350 today
  • $1000 investment in S&P 500 on January 1st, 2020 = $1050 today
Taken together, here’s the bottom bottom bottom line for a similar approach with the S&P:
After three $1,000 investments into an S&P 500 index fund in January 2018, 2019, and 2020, my portfolio would be worth $3,660.
That is up +22% since January 2018, compared to a +11% gain of the combined Top Ten Crypto Experiment Portfolios.
That’s an 11% swing in favor of the S&P 500 and breaks a two month mini-streak of wins from the Top Ten crypto portfolios.
S&P vs. Top Ten Crypto Experiments
That’s seven monthly victories for the S&P vs. two monthly victories for crypto. The largest gap so far was a 22% difference in favor of the S&P in June.

Conclusion:

September was a tough month for both traditional and crypto markets. What’s next for the rest of 2020? More volatility is no doubt to come as we enter the last quarter of a truly unpredictable and exhausting year. Buckle up.
Thanks for reading and for supporting the experiment. I hope you’ve found it helpful. I continue to be committed to seeing this process through and reporting along the way. Feel free to reach out with any questions and stay tuned for progress reports. Keep an eye out for my parallel projects where I repeat the experiment twice, purchasing another $1000 ($100 each) of two new sets of Top Ten cryptos as of January 1st, 2019 then again on January 1st, 2020.

And the Answer is…

C) Kraken
According to an official announcement in September, Kraken is “the first digital asset company in U.S. history to receive a bank charter recognized under federal and state law.”

The Fed's Losing Battle with Technological Deflation

PART 1/4 - FREE MARKET?
First off, let's set the scene.
The stock market is telling you nothing about the real economy anymore.
Economic fundamentals have never mattered as little for the stock market as has been the case during this 11-year bull market.
The correlation between gross-domestic-product growth and the direction of the S&P 500 Index has only been 7% in this cycle - historically it has been 30% to 70%.
Why?
Well, it is the Central Banks, led by the Fed, who printed their way out of the Recession in '08.
In doing so, they have papered over the cracks, and we have seen the longest economic expansion in US history.
However, this is not a particularly meritocratic process: money creation itself increases inequality via the Cantillon Effect, as money printing leads to asset price inflation, which disproportionately benefits the rich and hurts the poor.
Former Federal Reserve Chairman Paul Volcker told the New York Times in 2018:
“The central issue is we’re developing into a plutocracy. We’ve got an enormous number of enormously rich people that have convinced themselves that they’re rich because they’re smart and constructive."
The reality of course is that this is largely not the case - it is because the game is rigged in their favour.
Now, it is important to emphasise the fact that the path we have taken has resulted in the highest living standards we have seen in human history.
However, the issue, particularly since the US completely abandoned the gold standard in 1971, is that debt has exploded to obscene levels.
We are not operating in a free market if it takes $185 trillion of debt over the last 20 years to create 'growth'.
In fact, the global debt to GDP ratio hit an all-time high of 322% in the third quarter of 2019.
Inflation means that your dollar loses value and thus your purchasing power goes down.
Deflation means that the value of your dollar goes up and your purchasing power goes up.
That's a good thing right? You get more goods and services for less.
Well, no.
If you have deflation, debt explodes in real terms and you can never pay it back.
As the economy is based on debt, if you allow deflation, then you have to reset the debt.
This is why central banks fear deflation so much.
However, the major force driving the human race is technological progress - and this stops for no mortal...
PART 2/4 - TECHNOLOGICAL DEFLATION:
The increased abundance created by technology will result in massive job losses.
Throughout history, doom porn enthusiasts have screamed that the machines are coming for jobs. This is not a new phenomenon.
All technological revolutions are deflationary - since they create "supply side shocks", meaning that they allow for more intensive use of resources and thus higher production. With more goods being produced, all other things being equal, the price of those goods will fall.
In the last 20 years or so, software has disrupted and replaced many established goods and services.
It is in the next 20 years that another disruptive technology is set to take the stage: AI
According to Steve Schwarzman, the co-founder and CEO of The Blackstone Group who has a net worth of $17.6BN:
"This is going to touch everyone's life....you're not going to be able to get away from this technology"
Moreover, this virus will only accelerate this trend towards tech. Zoom is a fantastic example of exactly this.
Old legacy economic systems were not built for this tech deflation, and the thing about exponential growth is that we humans do not intuitively understand it.
As an example, if you folded a piece of paper 51 times, of course you can only fold it seven times, but if you could fold it 51 times, it would reach the Sun!
PART 3/4 - IMPLICATIONS FOR SOCIETY:
The question is: how does this play out?
In the long term, it is the fundamental structure of the economic system that has a significant impact on people's lives, not who is President for 4 to 8 years.
In reality, politicians have limited power and are effectively all puppets. We have seen what happens when a President doesn't stay in their lane...
One could argue that the two main mechanisms of control are:
  1. Divide and Conquer and
  2. Order from Chaos
As we have seen many times in the past, herd psychology is worryingly easy to manipulate...
Speaking of the censorship, in his book Antifragile, Nassim Taleb discusses the anti fragility of information.
Information feeds more on attempts to harm it than it does on efforts to promote it.
A fantastic example of this process is what has happened with London Real: they were banned on LinkedIn and David Icke's interview was censored. Now, regardless of what you think of this particular channel or your thoughts on David Icke and the theories provided, censoring information in this way actually spreads it more virally.
It's fascinating to observe how many views the videos regarding the bans and censorship have relative to the others. And the impact this has had on subscribers.
It is always easier to blame a bigger enemy (or create a new one) rather than to admit it's a structural problem.
Therefore, you avoid short term pain...whatever the cost.
The real question is if and when this situation will lead to social unrest...
PART 4/4 - INTELLECTUAL CAPITALISM:
The depth and width of jobs impacted by AI will continue to increase in the future.
Now this will not necessarily happen straight away.
However, our transition from commodity capitalism to intellectual capitalism is inevitable and the people and nations who fight against this trend will be on the wrong side of history.
From a practical investment perspective, and disclaimer this is not investment advice, network effects are a crucial aspect to consider moving forwards.
Essentially, this means that the value of the network increases with each additional user - all of the tech monopolies have exhibited this property.
An asset which could in time demonstrate very strong network effects is Bitcoin.
Looking at the market cap relative to other asset classes, Bitcoin provides an asymmetric investment opportunity.
Only time will tell...

I bought $1k of the Top Ten Cryptos on January 1st, 2018. August update, -71%, special NEM EDITION!!

I bought $1k of the Top Ten Cryptos on January 1st, 2018. August update, -71%, special NEM EDITION!!

EXPERIMENT - Tracking Top 10 Cryptos of 2018 - Month 32 (-71%)
See the full blog post with all the tables here.
tl;dr:
  • purchased $100 of each of Top Ten Cryptos in Jan. 2018, haven't sold or traded, repeated in 2019 and 2020, update y'all monthly. Learn more about the history and rules of the Experiments here.
  • August - solid month for the 2018 Top Ten, led by, ladies and gentlemen (or lady singular, there in the back row, I see you) NEM!!!!! Up over +200% in August.
  • Overall - BTC still way ahead and approaching break-even point, ETH gaining ground, alone in the middle. NEM(!!!) finally escapes last place replaced by DASH.
  • Over three years, cryptos outperforming S&P if I'd taken a similar approach.

Month Thirty Two – Down 71%

2018 Top Ten Summary
August was not quite as strong as all-green July, but still a solid month for the 2018 Top Ten Crypto Index Fund Experiment. The gains were led by (I hope you’re sitting down for this one) (drum roll please) (you’re not going to believe this): NEM(!) which finished the month up over +200%. Really!

Question of the month:

The US Justice Department announced in August that it had seized cryptocurrency from terror groups in the Middle East. How much did they confiscate?

A) $2 million B) $4 million C) $8 million D) $32 million
Scroll down for the answer.

Ranking and August Winners and Losers

Rank since January 2018
Lots of movement this month: all but three cryptos moved positions in August and all but one (NEM!) in the wrong direction. Despite gaining in value, Dash had the biggest slide, down four in the rankings from #24 to #28. ADA fell three and has dropped back out of the Top Ten. XRP, Bitcoin Cash, IOTA, and Stellar each lost one place in the rankings. The lone exception is a big one: XEM(!) climbed an unprecedented 9 spots in August. The last time NEM was in the Top Twenty was May 2019.
After thirty-two months, 50% of the cryptos that started 2018 in the Top Ten have dropped out. NEM, ADA, Dash, IOTA, and Stellar have been replaced by Binance Coin, Tether, BSV, CRO, and most recently, LINK.
August WinnersDon’t call it a comeback, NEM‘s been here for years. Up over +200% in August, NEM crushed the rest of the field. A distant second place was ETH, up +32% on the month.
August Losers – Down -13%, ADA was the worst performing crypto of the month, followed by Bitcoin Cash, down -9%.
For the overly competitive, below is a tally of the winners of the first 32 months of the 2018 Top Ten Crypto Index Fund Experiment. Bitcoin still has the most monthly wins (7). Cardano is a close second with 6 monthly wins. Despite its blockbuster August, NEM has the most monthly losses with 6. Every crypto has at least one monthly win and Bitcoin is unique as the only cryptocurrency that hasn’t lost a month in the 2.5+ years of the Experiment.
Ws and Ls

Overall update – BTC in the lead and inching towards break-even point, followed by second place ETH. NEM escapes last place, replaced by Dash.

Although BTC didn’t make any major moves this month, it continued to slowly but surely approach its break-even point. It is down about -10% since my purchase in January 2018. The initial investment of $100 thirty-two months ago is now worth about $90.
Ethereum is all alone in second place. It had a strong August, it picked up a lot of ground, but is still down -35% since January 2018.
The big story this month is at the bottom: NEM(!) gained +200% in August, crushing its counterparts and leaping out of last place, where it was so comfortable for so, so long. Although still down -83% over the life of the experiment, it moved from 10th place to 6th place in just one month. The new king of the basement is Dash, down -91%. The initial $100 invested in Dash 32 months ago is now worth $8.50.

Total Market Cap for the entire cryptocurrency sector:

The crypto market added nearly $43B in August. The last time we saw a similar level in terms of overall crypto market cap was way back in the fifth month of the 2018 Top Ten Experiment: May 2018.

Bitcoin dominance:

After being stuck in the mid-60s for most of 2020, BitDom dropped significantly this month, down to 57%. For context, the last time BitDom was this low was back in June 2019.
For some more context: since the beginning of the experiment, the range of Bitcoin dominance has been quite wide: we saw a high of 70% BitDom in September 2019 and a low of 33% BitDom in February 2018.

Overall return on $1,000 investment since January 1st, 2018:

The 2018 Top Ten Portfolio gained about $17 this month. If I cashed out today, the $1000 initial investment would return about $287, down -71% from January 2018.
While -71% isn’t something to brag about, the monthly trend is encouraging. Here, take a look at the ROI over the life of the experiment, month by month, for some context:
2018 Top Ten Monthly ROI Summary
So, -71% from a bottom of -88% is moving in the right direction.
Or that’s what I tell myself as I cry myself to sleep nightly.
Hopefully the next stop will be in the -60% range, a level this experiment hasn’t seen in years.
So the Top Ten Cryptos of 2018 are down -71%. What about the 2019 and 2020 Top Tens? Let’s take a look:
So overall? Taking the three portfolios together, here’s the bottom bottom bottom line:
After a $3000 investment in the 2018, 2019, and 2020 Top Ten Cryptocurrencies, my combined portfolios are worth $‭3,937‬ ($287+ $1,825 +$1,825).
That’s up about +31% for the three combined portfolios, compared to +23% last month. This marks the highest ROI of the three combined portfolios since I added the metric this year.
Here’s a table to help visualize:
Combined ROI on $3k over three years
A +31% gain by investing $1k on whichever cryptos happened to be in the Top Ten on January 1st for three straight years, not bad. But surely you’d do better if you invested only in one crypto, right? Depends on your choice. Let’s take a look:

Three year club: shoulda gone with ETH
Only five cryptos have remained in the Top Ten for all three years: BTC, ETH, XRP, BCH, and LTC. Knowing what we know now, which one would have been best to go all in on, at least at this point in the Experiment? Ethereum, easily: the initial $3k would be up +160%, worth over $7800 today. The worst performing at this point is XRP, down -17%.

Comparison to S&P 500:

I’m also tracking the S&P 500 as part of the experiment to have a comparison point with other popular investments options. Defying global gloom, the S&P 500 reached an all time high in August and is up +31% since the beginning of the Experiment. The initial $1k investment into crypto on January 1st, 2018 would have been worth about $1310 had it been redirected to the S&P.
But what if I took the same invest-$1,000-on-January-1st-of-each-year approach with the S&P 500 that I’ve been documenting through the Top Ten Crypto Experiments? Here are the numbers:
  • $1000 investment in S&P 500 on January 1st, 2018: +$310
  • $1000 investment in S&P 500 on January 1st, 2019: +$400
  • $1000 investment in S&P 500 on January 1st, 2020: +$90
Taken together, here’s the bottom bottom bottom line for a similar approach with the S&P:
After three $1,000 investments into an S&P 500 index fund in January 2018, 2019, and 2020, my portfolio would be worth $3,800.
That is up over+27% since January 2018, compared to a +31% gain of the combined Top Ten Crypto Experiment Portfolios.
That’s a 4% swing in favor of the Top Ten Crypto Portfolios! As you’ll see in the table below, this is only the second time since I started recording this metric that crypto has outperformed the S&P had I taken a similar investment approach:

3 x $1k crypto vs. S&P
This is a big turnaround from the 22% difference in favor of the S&P just two months ago.
Although it’s fun to see crypto is in the lead, I’ll leave it to you to decide whether the heart condition you may develop by being in the cryptosphere is worth that +4% edge…

Conclusion:

August was a bit mixed compared to July, but still a very solid month for the 2018 Top Ten. Some interesting developments this month: Bitcoin is now within 10% of the price I paid on January 1st, 2018. ETH had solid gains and NEM(!) had a crazy month, tripling in value and finally climbing out of the basement. At the same time, traditional markets are doing well too: the S&P reached an all time high in August. It will be interesting to see how both markets perform during the final third of a very crazy year.
Thanks for reading and for supporting the experiment. I hope you’ve found it helpful. I continue to be committed to seeing this process through and reporting along the way. Feel free to reach out with any questions and stay tuned for progress reports. Keep an eye out for my parallel projects where I repeat the experiment twice, purchasing another $1000 ($100 each) of two new sets of Top Ten cryptos as of January 1st, 2019 then again on January 1st, 2020.

And the Answer is…

A) $2 million
According to federal prosecutors, the US Justice Department seized $2 million worth of cryptocurrency from terror groups in the Middle East including ISIS, al Qaeda, and the al Qassam Brigades.

Now, regardless of what you think of this particular channel or your thoughts on David Icke and the theories provided, censoring information in this way actually spreads it more virally.
It's fascinating to observe how many views the videos regarding the bans and censorship have relative to the others. And the impact this has had on subscribers.
It is always easier to blame a bigger enemy (or create a new one) rather than to admit it's a structural problem.
Therefore, you avoid short term pain...whatever the cost.
The real question is if and when this situation will lead to social unrest...
PART 4/4 - INTELLECTUAL CAPITALISM:
The depth and width of jobs impacted by AI will continue to increase in the future.
Now this will not necessarily happen straight away.
However, our transition from commodity capitalism to intellectual capitalism is inevitable and the people and nations who fight against this trend will be on the wrong side of history.
From a practical investment perspective, and disclaimer this is not investment advice, network effects are a crucial aspect to consider moving forwards.
Essentially, this means that the value of the network increases with each additional user - all of the tech monopolies have exhibited this property.
An asset which could in time demonstrate very strong network effects is Bitcoin.
Looking at the market cap relative to other asset classes, Bitcoin provides an asymmetric investment opportunity.

The Fed's Losing Battle with Technological Deflation

PART 1/4 - FREE MARKET?
First off, let's set the scene.
The stock market is telling you nothing about the real economy anymore.
Economic fundamentals have never mattered as little for the stock market as has been the case during this 11-year bull market.
The correlation between gross-domestic-product growth and the direction of the S&P 500 Index has only been 7% in this cycle - historically it has been 30% to 70%.
Why?
Well, it is the Central Banks, led by the Fed, who printed their way out of the Recession in '08.
In doing so, they have papered over the cracks, and we have seen the longest economic expansion in US history.
However, this is not a particularly meritocratic process: money creation itself increases inequality via the Cantillon Effect, as money printing leads to asset price inflation, which disproportionately benefits the rich and hurts the poor.
Former Federal Reserve Chairman Paul Volcker told the New York Times in 2018:
“The central issue is we’re developing into a plutocracy. We’ve got an enormous number of enormously rich people that have convinced themselves that they’re rich because they’re smart and constructive."
The reality of course is that this is largely not the case - it is because the game is rigged in their favour.
Now, it is important to emphasise the fact that the path we have taken has resulted in the highest living standards we have seen in human history.
However, the issue, particularly since the US completely abandoned the gold standard in 1971, is that debt has exploded to obscene levels.
We are not operating in a free market if it takes $185 trillion of debt over the last 20 years to create 'growth'.
In fact, the global debt to GDP ratio hit an all-time high of 322% in the third quarter of 2019.
Inflation means that your dollar loses value and thus your purchasing power goes down.
Deflation means that the value of your dollar goes up and your purchasing power goes up.
That's a good thing right? You get more goods and services for less.
Well, no.
If you have deflation, debt explodes in real terms and you can never pay it back.
As the economy is based on debt, if you allow deflation, then you have to reset the debt.
This is why central banks fear deflation so much.
However, the major force driving the human race is technological progress - and this stops for no mortal...
PART 2/4 - TECHNOLOGICAL DEFLATION:
The increased abundance created by technology will result in massive job losses.
Throughout history, doom porn enthusiasts have screamed that the machines are coming for jobs. This is not a new phenomenon.
All technological revolutions are deflationary - since they create "supply side shocks", meaning that they allow for more intensive use of resources and thus higher production. With more goods being produced, all other things being equal, the price of those goods will fall.
In the last 20 years or so, software has disrupted and replaced many established goods and services.
It is in the next 20 years that another disruptive technology is set to take the stage: AI
According to Steve Schwarzman, the co-founder and CEO of The Blackstone Group who has a net worth of $17.6BN:
"This is going to touch everyone's life....you're not going to be able to get away from this technology"
Moreover, this virus will only accelerate this trend towards tech. Zoom is a fantastic example of exactly this.
Old legacy economic systems were not built for this tech deflation, and the thing about exponential growth is that we humans do not intuitively understand it.
As an example, if you folded a piece of paper 51 times, of course you can only fold it seven times, but if you could fold it 51 times, it would reach the Sun!
PART 3/4 - IMPLICATIONS FOR SOCIETY:
The question is: how does this play out?
In the long term, it is the fundamental structure of the economic system that has a significant impact on people's lives, not who is President for 4 to 8 years.
In reality, politicians have limited power and are effectively all puppets. We have seen what happens when a President doesn't stay in their lane...
One could argue that the two main mechanisms of control are:
  1. Divide and Conquer and
  2. Order from Chaos
As we have seen many times in the past, herd psychology is worryingly easy to manipulate...
Speaking of the censorship, in his book Antifragile, Nassim Taleb discusses the anti fragility of information.
Information feeds more on attempts to harm it than it does on efforts to promote it.
A fantastic example of this process is what has happened with London Real: they were banned on LinkedIn and David Icke's interview was censored. Now, regardless of what you think of this particular channel or your thoughts on David Icke and the theories provided, censoring information in this way actually spreads it more virally.
It's fascinating to observe how many views the videos regarding the bans and censorship have relative to the others. And the impact this has had on subscribers.
It is always easier to blame a bigger enemy (or create a new one) rather than to admit it's a structural problem.
Therefore, you avoid short term pain...whatever the cost.
The real question is if and when this situation will lead to social unrest...
PART 4/4 - INTELLECTUAL CAPITALISM:
The depth and width of jobs impacted by AI will continue to increase in the future.
Now this will not necessarily happen straight away.
However, our transition from commodity capitalism to intellectual capitalism is inevitable and the people and nations who fight against this trend will be on the wrong side of history.
From a practical investment perspective, and disclaimer this is not investment advice, network effects are a crucial aspect to consider moving forwards.
Essentially, this means that the value of the network increases with each additional user - all of the tech monopolies have exhibited this property.
An asset which could in time demonstrate very strong network effects is Bitcoin.

COVID

For Trading October 27th
Housing Numbers Missed
COVID, COVID, COVID!
Today’s market could have been worse, but I’m not sure how! Prices weakened overnight and then the news only got uglier as the morning progressed. Housing data took a turn for the worse and the selloff just accelerated with the DJIA hitting the low -965 around 1:45, but the bounce was nothing to write home about. We finished -650.19 (2.29%), NASDAQ -189.34 (1.64%), S&P 500 -64.42 (1.8%), the Russell -35.29 (2.15%) and the DJ Transports -275.32 (2.32%) the worst index, but not by enough to make a difference. Housing numbers (new home sales) was not only a disappointment on a month/month basis, but we also had a meaningful restatement of last month’s number from 1,011,000 to 994,000. This month we were expecting 1,022,000 and got 959,000. Tomorrow we have Durable goods, Consumer confidence, NAHB housing prices and Case-Shiller for August.
Our “open forum” on Discord, which allows you to interact with subscribers and others to allow direct questions and chart opinions on just about any stock, continues to grow with more participants every day. It is informative and allows me to share insights as the market is open and moving. The link is: https://discord.gg/ATvC7YZ and I will be there and active from before the open and all day. It’s a great place to share ideas and gain some insights, and we’ve grown to almost 3000 members.
Last week’s interview with Joe Moscato, CEO of GNBT is available today at https://youtu.be/rJBtqC75g3A It’s a great story and this stock (I believe) won’t stay at these levels once there is a wider understanding of what this company actually has going for it!!
Tonight’s closing comment video: https://youtu.be/4O9B_KkQ3Ao
SECTORS: Earnings was the big mover today for SAP.

OIL, $38.56 – 1.29, Oil has been locked into the current range and tried to break in either direction without success. Last week I said, “While I think it may resolve to the downside, I am not taking any new positions.” The stocks were lower today even though there has been a pickup in M&A activity in the group. XLE finished $29.30 -1.09 (3.59%).
GOLD $1,905.70 +.50 opened LOWER and managed to rally while the market for stocks sold off. There were several “unusual options action” looking for another 10-12% on the upside before year end.
BITCOIN: closed $13,045 +75. After breaking out over $10,000 we have had a “running correction” pushing prices toward $12,000, reaching a recovery high of $12220 Thursday, and after a day of rest in between, we resumed the rally touching $12,635, but have sold off back to support. We had 750 shares of GBTC and sold off 250 last week at $13.93 and 250 today @$14.19, and we still have 250 with a cost of $8.45. GBTC closed $14.30 -.06 today.
Tomorrow is another day.

/r/Scams Common Scam Master Post

Hello visitors and subscribers of scams! Here you will find a master list of common (and uncommon) scams that you may encounter online or in real life. Thank you to the many contributors who helped create this thread!

If you know of a scam that is not covered here, write a comment and it will be added to the next edition.

Blackmail email scam thread: https://www.reddit.com/Scams/comments/jij7zf/the_blackmail_email_scam_part_6/
Some of these articles are from small, local publications and refer to the scam happening in a specific area. Do not think that this means that the scam won't happen in your area.

Spoofing

Caller ID spoofing
It is very easy for anyone to make a phone call while having any number show up on the caller ID of the person receiving the phone call. Receiving a phone call from a certain number does not mean that the person/company who owns that number has actually called you.
Email spoofing
The "from" field of an email can be set by the sender, meaning that you can receive scam emails that look like they are from legitimate addresses. It's important to never click links in emails unless absolutely necessary, for example a password reset link you requested or an account activation link for an account you created.
SMS spoofing
SMS messages can be spoofed, so be wary of messages that seem to be from your friends or other trusted people.

The most common scams

The fake check scam (Credit to nimble2 for this part)
The fake check scam arises from many different situations (for instance, you applied for a job, or you are selling something on a place like Craigslist, or someone wants to purchase goods or services from your business, or you were offered a job as a mystery shopper, you were asked to wrap your car with an advertisement, or you received a check in the mail for no reason), but the bottom line is always something like this:
General fraudulent funds scams If somebody is asking you to accept and send out money as a favour or as part of a job, it is a fraudulent funds scam. It does not matter how they pay you, any payment on any service can be fraudulent and will be reversed when it is discovered to be fraudulent.
Phone verification code scams Someone will ask you to receive a verification text and then tell you to give them the code. Usually the code will come from Google Voice, or from Craigslist. In the Google version of the scam, your phone number will be used to verify a Google Voice account that the scammer will use to scam people with. In the Craigslist version of the scam, your phone number will be used to verify a Craigslist posting that the scammer will use to scam people. There is also an account takeover version of this scam that will involve the scammer sending a password reset token to your phone number and asking you for it.
Bitcoin job scams
Bitcoin job scams involve some sort of fraudulent funds transfer, usually a fake check although a fraudulent bank transfer can be used as well. The scammer will send you the fraudulent money and ask you to purchase bitcoins. This is a scam, and you will have zero recourse after you send the scammer bitcoins.
Email flooding
If you suddenly receive hundreds or thousands of spam emails, usually subscription confirmations, it's very likely that one of your online accounts has been taken over and is being used fraudulently. You should check any of your accounts that has a credit card linked to it, preferably from a computer other than the one you normally use. You should change all of your passwords to unique passwords and you should start using two factor authentication everywhere.
Cartel scam
You will be threatened by scammers who claim to be affiliated with a cartel. They may send you gory pictures and threaten your life and the lives of your family. Usually the victim will have attempted to contact an escort prior to the scam, but sometimes the scammers target people randomly. If you are targeted by a cartel scam all you need to do is ignore the scammers as their threats are clearly empty.
Boss/CEO scam A scammer will impersonate your boss or someone who works at your company and will ask you to run an errand for them, which will usually be purchasing gift cards and sending them the code. Once the scammer has the code, you have no recourse.
Employment certification scams
You will receive a job offer that is dependent on you completing a course or receiving a certification from a company the scammer tells you about. The scammer operates both websites and the job does not exist.
Craigslist fake payment scams
Scammers will ask you about your item that you have listed for sale on a site like Craigslist, and will ask to pay you via Paypal. They are scamming you, and the payment in most cases does not actually exist, the email you received was sent by the scammers. In cases where you have received a payment, the scammer can dispute the payment or the payment may be entirely fraudulent. The scammer will then either try to get you to send money to them using the fake funds that they did not send to you, or will ask you to ship the item, usually to a re-shipping facility or a parcel mule.
Craigslist Carfax/vehicle history scam
You'll encounter a scammer on Craigslist who wants to buy the vehicle you have listed, but they will ask for a VIN report from a random site that they have created and they will expect you to pay for it.
Double dip/recovery scammers
This is a scam aimed at people who have already fallen for a scam previously. Scammers will reach out to the victim and claim to be able to help the victim recover funds they lost in the scam.
General fraudulent funds scams The fake check scam is not the only scam that involves accepting fraudulent/fake funds and purchasing items for scammers. If your job or opportunity involves accepting money and then using that money, it is almost certainly a frauduent funds scam. Even if the payment is through a bank transfer, Paypal, Venmo, Zelle, Interac e-Transfer, etc, it does not matter.
Credit card debt scam
Fraudsters will offer to pay off your bills, and will do so with fraudulent funds. Sometimes it will be your credit card bill, but it can be any bill that can be paid online. Once they pay it off, they will ask you to send them money or purchase items for them. The fraudulent transaction will be reversed in the future and you will never be able to keep the money. This scam happens on sites like Craigslist, Twitter, Instagram, and also some dating sites, including SeekingArrangement.
The parcel mule scam
A scammer will contact you with a job opportunity that involves accepting and reshipping packages. The packages are either stolen or fraudulently obtained items, and you will not be paid by the scammer. Here is a news article about a scam victim who fell for this scam and reshipped over 20 packages containing fraudulently acquired goods.
The Skype sex scam
You're on Facebook and you get a friend request from a cute girl you've never met. She wants to start sexting and trading nudes. She'll ask you to send pictures or videos or get on webcam where she can see you naked with your face in the picture. The scam: There's no girl. You've sent nudes to a guy pretending to be a girl. As soon as he has the pictures he'll demand money and threaten to send the pictures to your friends and family. Sometimes the scammer will upload the video to a porn site or Youtube to show that they are serious.
What to do if you are a victim of this scam: You cannot buy silence, you can only rent it. Paying the blackmailer will show them that the information they have is valuable and they will come after you for more money. Let your friends and family know that you were scammed and tell them to ignore friend requests or messages from people they don't know. Also, make sure your privacy settings are locked down and consider deactivating your account.
The underage girl scam
You're on a dating site or app and you get contacted by a cute girl. She wants to start sexting and trading nudes. Eventually she stops communicating and you get a call from a pissed off guy claiming to be the girl's father, or a police officer, or a private investigator, or something else along those lines. Turns out the girl you were sexting is underage, and her parents want some money for various reasons, such as to pay for a new phone, to pay for therapy, etc. There is, of course, no girl. You were communicating with a scammer.
What to do if you are a victim of this scam: Stop picking up the phone when the scammers call. Do not pay them, or they will be after you for more money.
Phishing
Phishing is when a scammer tries to trick you into giving information to them, such as your password or private financial information. Phishing messages will usually look very similar to official messages, and sometimes they are identical. If you are ever required to login to a different account in order to use a service, you should be incredibly cautious.

PSA: you did not win a giftcard: https://old.reddit.com/Scams/comments/fffmle/psa_you_did_not_win_a_gift_card/
Sugar scams
Sugar scammers operate all over the internet and usually come in two varieties: advance-fee scams where the scammer will ask for a payment from you before sending you lots of money, and fake check style scams where the scammer will either pull a classic fake check scam, or will do a "bill pay" style scam that involves them paying your bills, or them giving you banking information to pay your bills. If you encounter these scammers, report their accounts and move on.
Google Hangouts
Google Hangouts is a messaging platform used extensively by all kinds of scammers. If you are talking with someone online and they want you to switch to Hangouts, they are likely a scammer and you should proceed with caution.
Publishers Clearing House scams
PCH scams are often advance-fee scams, where you will be promised lots of money after you make an initial payment. You will never need to pay if you win money from the real PCH.
Pet scams
You are looking for a specific breed of puppy, bird, or other pet. You come across a nice-looking website that claims to be breeding them and has some available right now - they may even be on sale! The breeders are not local to your area (and may not even list a physical location) but they assure you they can safely ship the pet to you after a deposit or full payment. If you go through with the payment, you will likely be contacted by the "shipper" who will inform you about an unexpected shipping/customs/processing fee required to deliver your new pet. But there was never any pet, both the "breeder" and the "shipper" are scammers, typically operating out of Africa. These sites are rampant and account for a large percentage of online pet seller websites - they typically have a similar layout/template (screenshot - example)
If you are considering buying a pet online, some easy things to check are: (1) The registration date of the domain (if it was created recently it is likely a scam website) (2) Reverse image search the pictures of available pets - you will usually find other scam websites using the same photos. (3) Copy a sentence/section of the text from the "about us" page and put it into google (in quotes) - these scammers often copy large parts of their website's text from other places. (4) Search for the domain name and look for entries on petscams.com or other scam-tracking sites. (5) Strongly consider buying/adopting your pet from a local shelter or breeder where you can see the animal in person before putting any money down.
Thanks to djscsi for this entry.
Fake shipping company scams
These scams usually start when you try to buy something illegal online. You will be scammed for the initial payment, and then you will receive an email from the fake shipping company telling you that you need to pay them some sort of fee or bribe. If you pay this, they will keep trying to scam you with increasingly absurd stories until you stop paying, at which point they will blackmail you. If you are involved in this scam, all you can do is ignore the scammers and move on, and try to dispute your payments if possible.
Chinese Upwork scam
Someone will ask you to create an Upwork or other freelancer site account for them and will offer money in return. You will not be paid, and they want to use the accounts to scam people.
Quickbooks invoice scam
This is a fake check style scam that takes advantage of Quickbooks.
The blackmail email scam The exact wording of the emails varies, but there are generally four main parts. They claim to have placed software/malware on a porn/adult video site, they claim to have a video of you masturbating or watching porn, they threaten to release the video to your friends/family/loved ones/boss/dog, and they demand that you pay them in order for them to delete the video. Rest assured that this is a very common spam campaign and there is no truth behind the email or the threats. Here are some news articles about this scam.
The blackmail mail scam
This is very similar to the blackmail email scam, but you will receive a letter in the mail.
Rental scams Usually on local sites like Craigslist, scammers will steal photos from legitimate real estate listings and will list them for rent at or below market rate. They will generally be hesitant to tell you the address of the property for "safety reasons" and you will not be able to see the unit. They will then ask you to pay them a deposit and they claim they will ship you the keys. In reality, your money is gone and you will have no recourse.
Craigslist vehicle scams A scammer will list a vehicle on Craigslist and will offer to ship you the car. In many cases they will also falsely claim to sell you the car through eBay or Amazon. If you are looking for a car on Craigslist and the seller says anything about shipping the car, having an agent, gives you a long story about why they are selling the car, or the listing price is far too low, you are talking to a scammer and you should ignore and move on.
Advance-fee scam, also known as the 419 scam, or the Nigerian prince scam. You will receive a communication from someone who claims that you are entitled to a large sum of money, or you can help them obtain a large sum of money. However, they will need money from you before you receive the large sum.
Man in the middle scams
Man in the middle scams are very common and very hard to detect. The scammer will impersonate a company or person you are legitimately doing business with, and they will ask you to send the money to one of their own bank accounts or one controlled by a money mule. They have gained access to the legitimate persons email address, so there will be nothing suspicious about the email. To prevent this, make contact in a different way that lets you verify that the person you are talking to is the person you think you are talking to.
Digit wallet scam
A variation of the fake check scam, the scammer sends you money through a digital wallet (i.e. Venmo, Apple Pay, Zelle, Cash App) along with a message claiming they've sent the money to the wrong person and a request to send the money back. Customer service for these digital wallets may even suggest that you send the money back. However, the money sent is from a stolen credit card and will be removed from your account after a few days. Your transfer is not reversed since it came from your own funds.
Cam girl voting/viewer scam
You will encounter a "cam girl" on a dating/messaging/social media/whatever site/app, and the scammer will ask you to go to their site and sign up with your credit card. They may offer a free show, or ask you to vote for them, or any number of other fake stories.
Amateur porn recruitment scam
You will encounter a "pornstar" on a dating/messaging/social media/whatever site/app, and the scammer will ask you to create an adult film with hehim, but first you need to do something. The story here is usually something to do with verifying your age, or you needing to take an STD test that involves sending money to a site operated by the scammer.
Hot girl SMS spam
You receive a text from a random number with a message along the lines of "Hey babe I'm here in town again if you wanted to meet up this time, are you around?" accompanied by a NSFW picture of a hot girl. It's spam, and they'll direct you to their scam website that requires a credit card.
Identity verification scam
You will encounter someone on a dating/messaging/social media/whatever site/app, and the scammer will ask that you verify your identity as they are worried about catfishing. The scammer operates the site, and you are not talking to whoever you think you are talking to.
This type of scam teases you with something, then tries to make you sign up for something else that costs money. The company involved is often innocent, but they turn a blind eye to the practice as it helps their bottom line, even if they have to occasionally issue refunds. A common variation takes place on dating sites/dating apps, where you will match with someone who claims to be a camgirl who wants you to sign up for a site and vote for her. Another variation takes place on local sites like Craigslist, where the scammers setup fake rental scams and demand that you go through a specific service for a credit check. Once you go through with it, the scammer will stop talking to you. Another variation also takes place on local sites like Craigslist, where scammers will contact you while you are selling a car and will ask you to purchase a Carfax-like report from a specific website.
Multi Level Marketing or Affiliate Marketing
You apply for a vague job listing for 'sales' on craigslist. Or maybe an old friend from high school adds you on Facebook and says they have an amazing business opportunity for you. Or maybe the well dressed guy who's always interviewing people in the Starbucks that you work at asks if you really want to be slinging coffee the rest of your life. The scam: MLMs are little more than pyramid schemes. They involve buying some sort of product (usually snake oil health products like body wraps or supplements) and shilling them to your friends and family. They claim that the really money is recruiting people underneath you who give you a slice of whatever they sell. And if those people underneath you recruit more people, you get a piece of their sales. Ideally if you big enough pyramid underneath you the money will roll in without any work on your part. Failure to see any profit will be your fault for not "wanting it enough." The companies will claim that you need to buy their extra training modules or webinars to really start selling. But in reality, the vast majority of people who buy into a MLM won't see a cent. At the end of the day all you'll be doing is annoying your friends and family with your constant recruitment efforts. What to look out for: Recruiters love to be vague. They won't tell you the name of the company or what exactly the job will entail. They'll pump you up with promises of "self-generating income", "being your own boss", and "owning your own company." They might ask you to read books about success and entrepreneurs. They're hoping you buy into the dream first. If you get approached via social media, check their timelines. MLMs will often instruct their victims to pretend that they've already made it. They'll constantly post about how they're hustling and making the big bucks and linking to youtube videos about success. Again, all very vague about what their job actually entails. If you think you're being recruited: Ask them what exactly the job is. If they can't answer its probably a MLM. Just walk away.

Phone scams

You should generally avoid answering or engaging with random phone calls. Picking up and engaging with a scam call tells the scammers that your phone number is active, and will usually lead to more calls.
Tax Call
You get a call from somebody claiming to be from your countries tax agency. They say you have unpaid taxes that need to be paid immediately, and you may be arrested or have other legal action taken against you if it is not paid. This scam has caused the American IRS, Canadian CRA, British HMRC, and Australian Tax Office to issue warnings. This scam happens in a wide variety of countries all over the world.
Warrant Call
Very similar to the tax call. You'll get a phone call from an "agent", "officer", "sheriff", or other law enforcement officer claiming that there is a warrant out for your arrest and you will be arrested very soon. They will then offer to settle everything for a fee, usually paid in giftcards.
[Legal Documents/Process Server Calls]
Very similar to the warrant call. You'll get a phone call from a scammer claiming that they are going to serve you legal documents, and they will threaten you with legal consequences if you refuse to comply. They may call themselves "investigators", and will sometimes give you a fake case number.
Student Loan Forgiveness Scam
Scammers will call you and tell you about a student loan forgiveness program, but they are interested in obtaining private information about you or demanding money in order to join the fake program.
Tech Support Call You receive a call from someone with a heavy accent claiming to be a technician Microsoft or your ISP. They inform you that your PC has a virus and your online banking and other accounts may be compromised if the virus is not removed. They'll have you type in commands and view diagnostics on your PC which shows proof of the virus. Then they'll have you install remote support software so the technician can work on your PC, remove the virus, and install security software. The cost of the labor and software can be hundreds of dollars. The scam: There's no virus. The technician isn't a technician and does not work for Microsoft or your ISP. Scammers (primarily out of India) use autodialers to cold-call everyone in the US. Any file they point out to you or command they have you run is completely benign. The software they sell you is either freeware or ineffective. What to do you if you're involved with this scam: If the scammers are remotely on your computer as you read this, turn off your PC or laptop via the power button immediately, and then if possible unplug your internet connection. Some of the more vindictive tech scammers have been known to create boot passwords on your computer if they think you've become wise to them and aren't going to pay up. Hang up on the scammers, block the number, and ignore any threats about payment. Performing a system restore on your PC is usually all that is required to remove the scammer's common remote access software. Reports of identity theft from fake tech calls are uncommon, but it would still be a good idea to change your passwords for online banking and monitor your accounts for any possible fraud. How to avoid: Ignore any calls claiming that your PC has a virus. Microsoft will never contact you. If you're unsure if a call claiming to be from your ISP is legit, hang up, and then dial the customer support number listed on a recent bill. If you have elderly relatives or family that isn't tech savvy, take the time to fill them in on this scam.
Chinese government scam
This scam is aimed at Chinese people living in Europe and North America, and involves a voicemail from someone claiming to be associated with the Chinese government, usually through the Chinese consulate/embassy, who is threatening legal action or making general threats.
Chinese shipping scam
This scam is similar to the Chinese government scam, but involves a seized/suspicious package, and the scammers will connect the victim to other scammers posing as Chinese government investigators.
Social security suspension scam
You will receive a call from someone claiming to work for the government regarding suspicious activity, fraud, or serious crimes connected to your social security number. You'll be asked to speak to an operator and the operator will explain the steps you need to follow in order to fix the problems. It's all a scam, and will lead to you losing money and could lead to identity theft if you give them private financial information.
Utilities cutoff
You get a call from someone who claims that they are from your utility company, and they claim that your utilities will be shut off unless you immediately pay. The scammer will usually ask for payment via gift cards, although they may ask for payment in other ways, such as Western Union or bitcoin.
Relative in custody Scammer claims to be the police, and they have your son/daughtenephew/estranged twin in custody. You need to post bail (for some reason in iTunes gift cards or MoneyGram) immediately or the consequences will never be the same.
Mexican family scam
This scam comes in many different flavours, but always involves someone in your family and Mexico. Sometimes the scammer will claim that your family member has been detained, sometimes the scammer will claim that your family member has been kidnapped, and sometimes the scammer will claim that your family member is injured and needs help.
General family scams
Scammers will gather a large amount of information about you and target your family members using different stories with the goal of gettimg them to send money.
One ring scam
Scammers will call you from an international number with the goal of getting you to return their call, causing you to incur expensive calling fees.

Online shopping scams

THE GOLDEN RULE OF ONLINE SHOPPING: If it sounds too good to be true, it probably is.
Dropshipping
An ad on reddit or social media sites like Facebook and Instagram offers items at huge discounts or even free (sometimes requiring you to reblog or like their page). They just ask you to pay shipping. The scam: The item will turn out to be very low quality and will take weeks or even months to arrive. Sometimes the item never arrives, and the store disappears or stops responding. The seller drop-ships the item from China. The item may only cost a few dollars, and the Chinese government actually pays for the shipping. You end up paying $10-$15 dollars for a $4 item, with the scammer keeping the profit. If you find one of these scams but really have your heart set on the item, you can find it on AliExpress or another Chinese retailer.
Influencer scams
A user will reach out to you on a social media platform, usually Instagram, and offer you the chance to partner with them and receive a free/discounted product, as long as you pay shipping. This is a different version of the dropshipping scam, and is just a marketing technique to get you to buy their products.
Triangulation fraud
Triangulation fraud occurs when you make a purchase on a site like Amazon or eBay for an item at a lower than market price, and receive an item that was clearly purchased new at full price. The scammer uses a stolen credit card to order your item, while the money from the listing is almost all profit for the scammer.
Instagram influencer scams
Someone will message you on Instagram asking you to promote their products, and offering you a discount code. The items are Chinese junk, and the offer is made to many people at a time.
Cheap Items
Many websites pop up and offer expensive products, including electronics, clothes, watches, sunglasses, and shoes at very low prices. The scam: Some sites are selling cheap knock-offs. Some will just take your money and run. What to do if you think you're involved with this scam: Contact your bank or credit card and dispute the charge. How to avoid: The sites often have every brand-name shoe or fashion item (Air Jordan, Yeezy, Gucci, etc) in stock and often at a discounted price. The site will claim to be an outlet for a major brand or even a specific line or item. The site will have images at the bottom claiming to be Secured by Norton or various official payment processors but not actual links. The site will have poor grammar and a mish-mash of categories. Recently, established websites will get hacked or their domain name jacked and turned into scam stores, meaning the domain name of the store will be completely unrelated to the items they're selling. If the deal sounds too good to be true it probably is. Nobody is offering brand new iPhones or Beats or Nintendo Switches for 75% off.
Cheap Amazon 3rd Party Items
You're on Amazon or maybe just Googling for an item and you see it for an unbelievable price from a third-party seller. You know Amazon has your back so you order it. The scam: One of three things usually happen: 1) The seller marks the items as shipped and sends a fake tracking number. Amazon releases the funds to the seller, and the seller disappears. Amazon ultimately refunds your money. 2) The seller immediately cancels the order and instructs you to re-order the item directly from their website, usually with the guarantee that the order is still protected by Amazon. The seller takes your money and runs. Amazon informs you that they do not offer protection on items sold outside of Amazon and cannot help you. 2) The seller immediately cancels the order and instructs you to instead send payment via an unused Amazon gift card by sending the code on the back via email. Once the seller uses the code, the money on the card is gone and cannot be refunded. How to avoid: These scammers can be identified by looking at their Amazon storefronts. They'll be brand new sellers offering a wide range of items at unbelievable prices. Usually their Amazon names will be gibberish, or a variation on FIRSTNAME.LASTNAME. Occasionally however, established storefronts will be hacked. If the deal is too good to be true its most likely a scam.
Scams on eBay
There are scams on eBay targeting both buyers and sellers. As a seller, you should look out for people who privately message you regarding the order, especially if they ask you to ship to a different address or ask to negotiate via text/email/a messaging service. As a buyer you should look out for new accounts selling in-demand items, established accounts selling in-demand items that they have no previous connection to (you can check their feedback history for a general idea of what they bought/sold in the past), and lookout for people who ask you to go off eBay and use another service to complete the transaction. In many cases you will receive a fake tracking number and your money will be help up for up to a month.
Scams on Amazon
There are scams on Amazon targeting both buyers and sellers. As a seller, you should look out for people who message you about a listing. As a buyer you should look out for listings that have an email address for you to contact the person to complete the transaction, and you should look out for cheap listings of in-demand items.
Scams on Reddit
Reddit accounts are frequently purchased and sold by fraudsters who wish to use the high karma count + the age of the account to scam people on buy/sell subreddits. You need to take precautions and be safe whenever you are making a transaction online.
Computer scams
Virus scam
A popup or other ad will say that you have a virus and you need to follow their advice in order to remove it. They are lying, and either want you to install malware or pay for their software.

Assorted scams

Chinese Brushing / direct shipping
If you have ever received an unsolicited small package from China, your address was used to brush. Vendors place fake orders for their own products and send out the orders so that they can increase their ratings.
Money flipping
Scammer claims to be a banking insider who can double/triple/bazoople any amount of money you send them, with no consequences of any kind. Obviously, the money disappears into their wallet the moment you send it.

vectorbt - blazingly fast backtesting and interactive data analysis for quants

I want to share with you a tool that I was continuously developing during the last couple of months.
https://github.com/polakowo/vectorbt

As a data scientist, when I first started flirting with quant trading, I quickly realized that there is a shortage of Python packages that can actually enable me to iterate over a long list of possible strategies and hyper-parameters quickly. Most open-source backtesting libraries are very evolved in terms of functionality, but simply lack speed. Questions like "Which strategy is better: X or Y?" require fast computation and transformation of data. This not only prolongs your lifecycle of designing strategies, but is dangerous after all: limited number of tests is similar to a tunnel vision - it prevents you from seeing the bigger picture and makes you dive into the market blindly.
After trying tweaking pandas, multiprocessing, and even evaluating my strategies on a cluster with Spark, I finally found myself using Numba - a Python library that can compile slow Python code to be run at native machine code speed. And since there were no packages in the Python ecosystem that could even closely match the speed of my own backtests, I made vectorbt.
vectorbt combines pandas, NumPy and Numba sauce to obtain orders-of-magnitude speedup over other libraries. It builds upon the idea that each instance of a trading strategy can be represented in a vectorized form, so multiple strategy instances can be packed into a single multi-dimensional array. In this form, they can processed in a highly efficient manner and compared easily. It also integrates Plotly and ipywidgets to display complex charts and dashboards akin to Tableau right in the Jupyter notebook. You can find basic examples and explanations in the documentation.

Below is an example of doing in total 67,032 tests on three different timeframes of Bitcoin price history to explore how performance of a MACD strategy depends upon various combinations of fast, slow and signal windows:
import vectorbt as vbt import numpy as np import yfinance as yf from itertools import combinations, product # Fetch daily price of Bitcoin price = yf.Ticker("BTC-USD").history(period="max")['Close'] price = price.vbt.split_into_ranges(n=3) # Define hyper-parameter space # 49 fast x 49 slow x 19 signal fast_windows, slow_windows, signal_windows = vbt.indicators.create_param_combs( (product, (combinations, np.arange(2, 51, 1), 2), np.arange(2, 21, 1))) # Run MACD indicator macd_ind = vbt.MACD.from_params( price, fast_window=fast_windows, slow_window=slow_windows, signal_window=signal_windows, hide_params=['macd_ewm', 'signal_ewm'] ) # Long when MACD is above zero AND signal entries = macd_ind.macd_above(0) & macd_ind.macd_above(macd_ind.signal) # Short when MACD is below zero OR signal exits = macd_ind.macd_below(0) | macd_ind.macd_below(macd_ind.signal) # Build portfolio portfolio = vbt.Portfolio.from_signals( price.vbt.tile(len(fast_windows)), entries, exits, fees=0.001, freq='1D') # Draw all window combinations as a 3D volume fig = portfolio.total_return.vbt.volume( x_level='macd_fast_window', y_level='macd_slow_window', z_level='macd_signal_window', slider_level='range_start', template='plotly_dark', trace_kwargs=dict( colorscale='Viridis', colorbar=dict( title='Total return', tickformat='%' ) ) ) fig.show() 

https://reddit.com/link/hxl6bn/video/180sxqa8mzc51/player
From signal generation to data visualization, the example above needs roughly a minute to run.

vectorbt let's you
The current implementation has limitations though:

If it sounds cool enough, try it out! I would love if you'd give me some feedback and contribute to it at some point, as the codebase has grown very fast. Cheers.

Introducing Bondly…

Introducing Bondly…
For us who use Decentralized Finance (DeFi) as a common term, we know it represents an enormous shift in how we transact with one another: borrowing money, exchanging currencies, how we view insurance, etc. While total assets involved in DeFi still seem to be increasing right now, there are various factors that will prevent us from growing further.
DeFi’s largest barriers for adoption
Interoperability — Right now Ethereum gas fees seem like they are always increasing and ETH 2.0 may still be 6 months or more away. We need the ability to make DeFi more accessible to individuals who can’t afford high gas prices per transaction and start including native blockchain assets that are stranded on other platforms.
Trust — Unfortunately our biggest issue is still trust. While none of us in crypto expect to know the identity of the other party, many of us just send funds to people we don’t know for vague promises of more wealth. In fact, the biggest type of fraud is still the “giveaway scam” which asks offer to send something back — but its only an offer, there is no guarantee. This is totally unsustainable.
What about doing business outside of crypto?
Ultimately, DeFi doesn’t keep going unless we create methods for non-crypto native businesses to integrate. While the community might approve sending crypto to each other without a safety in place, this will never work for 99% of online marketplaces.
So we need:
  • DeFi options on lower cost platforms
  • Trading across blockchains
  • Safer Transactions
  • More flexibility for peer to peer transactions
  • Easier methods for online marketplaces to integrate and use crypto
This is why we created Bondly.

https://preview.redd.it/5gs8v5ce1hu51.png?width=1400&format=png&auto=webp&s=fade2f7576626022460b7882f379552d44b678c7
Bondly is a brainchild of over 3 years of working in fintech digital escrow payments + love for native DeFi. Adding our cumulative 13 years of traditional financial services, 6 years of eCommerce marketing, 4 years of Ethereum blockchain development, we think this will be one of the most important next steps in DeFi.

What is Bondly?

Bondly is a trusted, transparent and portable swap protocol designed to make you into a marketplace.
Our family of trust-enabling, DeFi products are designed to be a part of your everyday buying and selling activities, giving you piece of mind for your next swap or online purchase.

BONDSWAP (BSWAP)

Similar to Binance OTC Trading Portal but directly on-chain and can be sent via any chat app using different blockchains
Wallet to Wallet trustless Over the Counter (OTC) trades that are performed by signing a smart contract. Completely portable smart link can be sent via a chat app or on your favorite social media. It will first support all ERC-20 tokens and NFT (Ethereum) then eventually
With BSWAP you can:
  • Sell a large order of a low liquidity token with no risk of slippage
  • Become your own NFT marketplace by minting the token, setting your own price, then post to your social media for your audience to buy
  • Buy assets using Debit/Credit card (using our third party partner onramp)
  • Send smart link in Telegram to someone you know or your favorite group

BOND DEX

Similar to Mooniswap but includes rewards token provided to Liquidity Providers on top of fee share
Interoperable Decentralized Exchange (DEX) thats easy to use and blockchain agnostic. Requires liquidity provider (LP) participants to pool assets for a portion of transaction fees along with rewards APY rewards. Our pricing engine will compare major cross chain swap options and will let you know the best one to use (even if its not us). Validation is done directly within your Web3 browser (with Metamask) or polkadot.js based Native Wallet.
With BOND DEX you can:
  • Trade native assets on Polkadot with USDC on Ethereum
  • Get recommendations on the cheapest bridge transaction path
  • Create your own asset pairs that otherwise might not exist

BOND PROTECT (BPROTECT)

Similar to Paypal/AliPay Express Buyer Protection combined with Escrow.com with a simple UX like Zapper.fi or Zircon
This is our most revolutionary product that we feel will have the largest impact to the eCommerce market.
PROTECT is decentralized escrow and buyer protection for customers of crypto friendly marketplaces.
  • Designed to replace all site specific crypto escrow products with an easy to use API and completely smart contract driven product. Marketplaces may still be in a ‘validator’ role for the marketplace transaction but now they don’t have direct access to funds. This mitigates misappropriation by the marketplace along with exit scamming
  • By participating in the Bondly network, marketplace vendors can represent themselves as BPROTECT ready and show their on-chain transaction history and successful Bondly enabled deals
  • BPROTECT will have a similar UX to Zapper.Fi that will pull this vendors on chain activity and history into one place across ethereum and our native substrate chain so you can see their status and history
  • Functions as a ‘Buyer Protection’ similar to most major marketplaces, where customers are protected by collateral within Bondly
  • First customers will be marketplaces that sell digital goods like Domain Names and In-Game items and that support crypto payments already. Existing domain name credentials and ownership will be wrapped in an NFT and swapped for requested crypto directly
  • Requires that the marketplace itself stakes Bondly collateral as well as each individual marketplace vendor
  • COMPLETELY UNDERCUTS the whole ‘fake review’ industry which is prominently used to inflate value on sites like Amazon.com
With BPROTECT you can
  • Give more trust to your buyers that you will provide the purchased asset in a timely fashion
  • As a buyer you can request sellers to use this method so you have more trust
  • Sell an asset via OTC that you do not have yet (e.g. waiting for vesting) by staking collateral in the Bondly network
  • Set up recurring payments from individuals to vendors that can deduct from your account every month, similar to a Netflix subscription completely crypto enabled

How does BOND PROTECT work?

For individual OTC Trades:
  • Seller stakes collateral and ensures the buyer will receive asset by a specified date or with a specific condition
  • If agreement is violated, collateral is forfeited and transferred to the buyer
For Marketplace Vendors:
  • Vendors stake collateral (earning staking rewards for doing so)
  • Should a vendor violate a sale condition (e.g. not deliver a good on time), BOND collateral is provided to buyers as compensation
  • Each sale is recorded on-chain for transparency
  • Vendors who provide extended positive service with a long term history are rewarded through our staking/LP rewards program

https://preview.redd.it/3t8a39rh1hu51.png?width=737&format=png&auto=webp&s=6c9e1f41cc862859bbee1e263f740bbe6a106057

Bonding with Polkadot

As our ‘sibling’ projects Darwinia and Bifrost have realized, Polkadot and using Substrate represents a phenomenal step forward in interoperability.
It offers:
  • Total flexibility for building a cross asset non-custodial token bridge
  • Seamless integration of our partners/peer bridges between infrastructure
  • Built in network security
  • Efficient token standard indexing for every type of asset in every type of blockchain
We don’t have Digital Money without Bitcoin; We don’t have Smart Contracts and DeFi without Ethereum; We don’t have true interoperability without Polkadot and Substrate.
In a future article we will talk more about our Kusama testnet release.

Whats next for BONDLY?

BONDSWAP for Ethereum, the first formal product release, will be available soon (so hold off on your OTC transaction until then). This will include support for the Bondly staking program. Detailed roadmaps for the other products will be announced soon!
In the meantime we will be making additional articles (but not limited to) the following topics:
  • Our first BPROTECT marketplace customers
  • The BONDLY Liquidity Marketplace
  • Partnership Announcements
  • Team Details
Please join our community and sign up for the alpha! We are so excited to share more with you soon!

The Fed's Losing Battle with Technological Deflation

PART 1/4 - FREE MARKET?
First off, let's set the scene.
The stock market is telling you nothing about the real economy anymore.
Economic fundamentals have never mattered as little for the stock market as has been the case during this 11-year bull market.
The correlation between gross-domestic-product growth and the direction of the S&P 500 Index has only been 7% in this cycle - historically it has been 30% to 70%.
Why?
Well, it is the Central Banks, led by the Fed, who printed their way out of the Recession in '08.
In doing so, they have papered over the cracks, and we have seen the longest economic expansion in US history.
However, this is not a particularly meritocratic process: money creation itself increases inequality via the Cantillon Effect, as money printing leads to asset price inflation, which disproportionately benefits the rich and hurts the poor.
Former Federal Reserve Chairman Paul Volcker told the New York Times in 2018:
“The central issue is we’re developing into a plutocracy. We’ve got an enormous number of enormously rich people that have convinced themselves that they’re rich because they’re smart and constructive."
The reality of course is that this is largely not the case - it is because the game is rigged in their favour.
Now, it is important to emphasise the fact that the path we have taken has resulted in the highest living standards we have seen in human history.
However, the issue, particularly since the US completely abandoned the gold standard in 1971, is that debt has exploded to obscene levels.
We are not operating in a free market if it takes $185 trillion of debt over the last 20 years to create 'growth'.
In fact, the global debt to GDP ratio hit an all-time high of 322% in the third quarter of 2019.
Inflation means that your dollar loses value and thus your purchasing power goes down.
Deflation means that the value of your dollar goes up and your purchasing power goes up.
That's a good thing right? You get more goods and services for less.
Well, no.
If you have deflation, debt explodes in real terms and you can never pay it back.
As the economy is based on debt, if you allow deflation, then you have to reset the debt.
This is why central banks fear deflation so much.
However, the major force driving the human race is technological progress - and this stops for no mortal...
PART 2/4 - TECHNOLOGICAL DEFLATION:
The increased abundance created by technology will result in massive job losses.
Throughout history, doom porn enthusiasts have screamed that the machines are coming for jobs. This is not a new phenomenon.
All technological revolutions are deflationary - since they create "supply side shocks", meaning that they allow for more intensive use of resources and thus higher production. With more goods being produced, all other things being equal, the price of those goods will fall.
In the last 20 years or so, software has disrupted and replaced many established goods and services.
It is in the next 20 years that another disruptive technology is set to take the stage: AI
According to Steve Schwarzman, the co-founder and CEO of The Blackstone Group who has a net worth of $17.6BN:
"This is going to touch everyone's life....you're not going to be able to get away from this technology"
Moreover, this virus will only accelerate this trend towards tech. Zoom is a fantastic example of exactly this.
Old legacy economic systems were not built for this tech deflation, and the thing about exponential growth is that we humans do not intuitively understand it.
As an example, if you folded a piece of paper 51 times, of course you can only fold it seven times, but if you could fold it 51 times, it would reach the Sun!
PART 3/4 - IMPLICATIONS FOR SOCIETY:
The question is: how does this play out?
In the long term, it is the fundamental structure of the economic system that has a significant impact on people's lives, not who is President for 4 to 8 years.
In reality, politicians have limited power and are effectively all puppets. We have seen what happens when a President doesn't stay in their lane...
One could argue that the two main mechanisms of control are:
  1. Divide and Conquer and
  2. Order from Chaos
As we have seen many times in the past, herd psychology is worryingly easy to manipulate...
Speaking of the censorship, in his book Antifragile, Nassim Taleb discusses the anti fragility of information.
Information feeds more on attempts to harm it than it does on efforts to promote it.
A fantastic example of this process is what has happened with London Real: they were banned on LinkedIn and David Icke's interview was censored. Now, regardless of what you think of this particular channel or your thoughts on David Icke and the theories provided, censoring information in this way actually spreads it more virally.
It's fascinating to observe how many views the videos regarding the bans and censorship have relative to the others. And the impact this has had on subscribers.
It is always easier to blame a bigger enemy (or create a new one) rather than to admit it's a structural problem.
Therefore, you avoid short term pain...whatever the cost.
The real question is if and when this situation will lead to social unrest...
PART 4/4 - INTELLECTUAL CAPITALISM:
The depth and width of jobs impacted by AI will continue to increase in the future.
Now this will not necessarily happen straight away.
However, our transition from commodity capitalism to intellectual capitalism is inevitable and the people and nations who fight against this trend will be on the wrong side of history.
From a practical investment perspective, and disclaimer this is not investment advice, network effects are a crucial aspect to consider moving forwards.
Essentially, this means that the value of the network increases with each additional user - all of the tech monopolies have exhibited this property.
An asset which could in time demonstrate very strong network effects is Bitcoin.
Looking at the market cap relative to other asset classes, Bitcoin provides an asymmetric investment opportunity.
Only time will tell...

Wall Street Breakfast: Volatile Week Ends In Quad Witching Session

U.S. equity futures held up overnight following another selloff on Wall Street that was led by major tech names. Contracts tied to the Dow and S&P 500 are hugging the flatline, while Nasdaq futures pared recent losses by climbing 0.6%. Mixed messaging around a potential coronavirus vaccine, as well as the passage of further fiscal stimulus, weighed on the market, while investors are gearing up for consumer sentiment data set for release at 10 a.m. ET. Don't forget that it's also quad witching day, which refers to the simultaneous expiration of market index futures, stock futures, market index options and stock options. "These days tend to get a lot of press for all of the volume they create, but historically they are nearly always a non-event," said Ryan Detrick, senior market strategist at LPL Financial.
Spending deal to avoid government shutdown
While there may be disagreement over another round of coronavirus relief, lawmakers are aiming to unveil a bipartisan spending bill today to avert a government shutdown on Oct. 1. The "clean" legislation, largely devoid of any controversial measures, should keep the government funded into mid-December. "I don't think anybody wants to be responsible for shutting down the government on the eve of an election in the middle of a pandemic, so it's a rare outbreak of common sense on both sides," said Rep. Tom Cole (R., Okla.), a senior member of the House Appropriations Committee.
New round of farm aid
"Starting next week my administration is committing an additional $13B in relief to help farmers recover from the China virus," President Trump announced a campaign rally in Mosinee, Wisconsin. The new aid is the second tranche of money issued as part of the Trump administration's Coronavirus Food Assistance Program. In April, the administration unveiled $19B in relief for the agriculture sector under the CARES Act, including $16B in direct payments to farmers and ranchers and $3B in mass purchases of dairy, meat and produce.
Fed mulls extension of bank dividend curbs
Due to heightened economic uncertainty, the Federal Reserve is considering extending its caps on banks' dividends and stock repurchases for the rest of the year. The U.S. central bank made the announcement along with its release of hypothetical scenarios for the second round of stress tests that it's requiring due to the COVID-19 pandemic. Unlike an earlier round of stress tests this year, the Fed will release the results of the tests for each of the 33 lenders, rather than providing aggregate results for the group.
Sub-zero rates
The Bank of England held its benchmark policy rate at 0.1% on Thursday, but indicated it could cut interest rates below zero for the first time in its 326-year history. While recent domestic economic data has been a bit stronger than expected, it's "unclear how the economy will perform further out," according to the Monetary Policy Committee. Another major risk facing the U.K. economy relates to the post-Brexit trade discussions between the U.K. and the EU, which have recently soured.
Terms of a TikTok deal
The Trump administration spent Thursday reviewing proposals on the TikTok-Oracle (NYSE:ORCL) partnership, which currently has many moving parts. TikTok owner ByteDance (BDNCE) agreed to list the video-sharing app on a U.S. stock exchange, which could happen within a year, though there are still concerns over whether the Chinese parent would be allowed to retain a majority stake in the new company. Meanwhile, shares in China's Tencent (OTCPK:TCEHY) tumbled into the U.S. closing bell following reports that its investments are drawing new national security attention.
Exchange dealmaking
Seeing off competing bids from Deutsche Borse (OTCPK:DBORY) and Switzerland's SIX, the London Stock Exchange (OTCPK:LNSTY) is in exclusive talks to sell Borsa Italiana to France's Euronext (OTCPK:EUXTF). Offloading the Milan stock exchange would help LSE achieve regulatory remedies for its $27B purchase of data provider Refinitiv, which is owned by Blackstone (NYSE:BX) and Thomson Reuters (NYSE:TRI). The deal is politically sensitive in Rome because of concerns about who could take control of Borsa Italiana's bond platform, which handles trading of Italy's government debt.
New COVID-19 restrictions across Europe
Targeted lockdowns and local restrictions are returning to Europe as the region tries to avoid broad economic damage amid a surge in coronavirus cases. "Weekly cases have now exceeded those reported when the pandemic first peaked in Europe in March," the WHO's regional director for Europe Hans Kluge told an online news conference. "Although these numbers reflect more comprehensive testing, it also shows alarming rates of transmission across the region." Pubs and restaurants must shut early and household mixing has been limited in northeast England, while social gatherings of more than six people have been banned across the country. French authorities are meanwhile preparing tighter restrictions in several cities, while Spain's Madrid has moved to "reduce mobility and contacts" in areas with high infection rates. Go Deeper: Israel becomes first developed country to enforce a second nationwide shutdown.
Pandemic closures see restaurants hit the hardest
About 60% of businesses that have closed their doors during the coronavirus pandemic will never reopen, and restaurants have suffered the most, according to new data from Yelp. The National Restaurant Association also said this week that 100,000 restaurants have closed either permanently or long term, adding that the sector is on track to lose $240B in sales this year. A number of factors have made it especially difficult for eateries, which tend to operate on thin margins even in the best of times.

Submitted for consideration to The Great Reddit Scaling Bake-Off
Baked by the pastry chefs at Offchain Labs
Please send questions or comments to [[email protected] ](mailto:[email protected])
1. Overview
We're excited to submit Arbitrum Rollup for consideration to The Great Reddit Scaling Bake-Off. Arbitrum Rollup is the only Ethereum scaling solution that supports arbitrary smart contracts without compromising on Ethereum's security or adding points of centralization. For Reddit, this means that Arbitrum can not only scale the minting and transfer of Community Points, but it can foster a creative ecosystem built around Reddit Community Points enabling points to be used in a wide variety of third party applications. That's right -- you can have your cake and eat it too!
Arbitrum Rollup isn't just Ethereum-style. Its Layer 2 transactions are byte-for-byte identical to Ethereum, which means Ethereum users can continue to use their existing addresses and wallets, and Ethereum developers can continue to use their favorite toolchains and development environments out-of-the-box with Arbitrum. Coupling Arbitrum’s tooling-compatibility with its trustless asset interoperability, Reddit not only can scale but can onboard the entire Ethereum community at no cost by giving them the same experience they already know and love (well, certainly know).
To benchmark how Arbitrum can scale Reddit Community Points, we launched the Reddit contracts on an Arbitrum Rollup chain. Since Arbitrum provides full Solidity support, we didn't have to rewrite the Reddit contracts or try to mimic their functionality using an unfamiliar paradigm. Nope, none of that. We launched the Reddit contracts unmodified on Arbitrum Rollup complete with support for minting and distributing points. Like every Arbitrum Rollup chain, the chain included a bridge interface in which users can transfer Community Points or any other asset between the L1 and L2 chains. Arbitrum Rollup chains also support dynamic contract loading, which would allow third-party developers to launch custom ecosystem apps that integrate with Community Points on the very same chain that runs the Reddit contracts.
1.1 Why Ethereum
Perhaps the most exciting benefit of distributing Community Points using a blockchain is the ability to seamlessly port points to other applications and use them in a wide variety of contexts. Applications may include simple transfers such as a restaurant that allows Redditors to spend points on drinks. Or it may include complex smart contracts -- such as placing Community Points as a wager for a multiparty game or as collateral in a financial contract.
The common denominator between all of the fun uses of Reddit points is that it needs a thriving ecosystem of both users and developers, and the Ethereum blockchain is perhaps the only smart contract platform with significant adoption today. While many Layer 1 blockchains boast lower cost or higher throughput than the Ethereum blockchain, more often than not, these attributes mask the reality of little usage, weaker security, or both.
Perhaps another platform with significant usage will rise in the future. But today, Ethereum captures the mindshare of the blockchain community, and for Community Points to provide the most utility, the Ethereum blockchain is the natural choice.
1.2 Why Arbitrum
While Ethereum's ecosystem is unmatched, the reality is that fees are high and capacity is too low to support the scale of Reddit Community Points. Enter Arbitrum. Arbitrum Rollup provides all of the ecosystem benefits of Ethereum, but with orders of magnitude more capacity and at a fraction of the cost of native Ethereum smart contracts. And most of all, we don't change the experience from users. They continue to use the same wallets, addresses, languages, and tools.
Arbitrum Rollup is not the only solution that can scale payments, but it is the only developed solution that can scale both payments and arbitrary smart contracts trustlessly, which means that third party users can build highly scalable add-on apps that can be used without withdrawing money from the Rollup chain. If you believe that Reddit users will want to use their Community Points in smart contracts--and we believe they will--then it makes the most sense to choose a single scaling solution that can support the entire ecosystem, eliminating friction for users.
We view being able to run smart contracts in the same scaling solution as fundamentally critical since if there's significant demand in running smart contracts from Reddit's ecosystem, this would be a load on Ethereum and would itself require a scaling solution. Moreover, having different scaling solutions for the minting/distribution/spending of points and for third party apps would be burdensome for users as they'd have to constantly shuffle their Points back and forth.
2. Arbitrum at a glance
Arbitrum Rollup has a unique value proposition as it offers a combination of features that no other scaling solution achieves. Here we highlight its core attributes.
Decentralized. Arbitrum Rollup is as decentralized as Ethereum. Unlike some other Layer 2 scaling projects, Arbitrum Rollup doesn't have any centralized components or centralized operators who can censor users or delay transactions. Even in non-custodial systems, centralized components provide a risk as the operators are generally incentivized to increase their profit by extracting rent from users often in ways that severely degrade user experience. Even if centralized operators are altruistic, centralized components are subject to hacking, coercion, and potential liability.
Massive Scaling. Arbitrum achieves order of magnitude scaling over Ethereum's L1 smart contracts. Our software currently supports 453 transactions-per-second for basic transactions (at 1616 Ethereum gas per tx). We have a lot of room left to optimize (e.g. aggregating signatures), and over the next several months capacity will increase significantly. As described in detail below, Arbitrum can easily support and surpass Reddit's anticipated initial load, and its capacity will continue to improve as Reddit's capacity needs grow.
Low cost. The cost of running Arbitrum Rollup is quite low compared to L1 Ethereum and other scaling solutions such as those based on zero-knowledge proofs. Layer 2 fees are low, fixed, and predictable and should not be overly burdensome for Reddit to cover. Nobody needs to use special equipment or high-end machines. Arbitrum requires validators, which is a permissionless role that can be run on any reasonable on-line machine. Although anybody can act as a validator, in order to protect against a “tragedy of the commons” and make sure reputable validators are participating, we support a notion of “invited validators” that are compensated for their costs. In general, users pay (low) fees to cover the invited validators’ costs, but we imagine that Reddit may cover this cost for its users. See more on the costs and validator options below.
Ethereum Developer Experience. Not only does Arbitrum support EVM smart contracts, but the developer experience is identical to that of L1 Ethereum contracts and fully compatible with Ethereum tooling. Developers can port existing Solidity apps or write new ones using their favorite and familiar toolchains (e.g. Truffle, Buidler). There are no new languages or coding paradigms to learn.
Ethereum wallet compatibility. Just as in Ethereum, Arbitrum users need only hold keys, but do not have to store any coin history or additional data to protect or access their funds. Since Arbitrum transactions are semantically identical to Ethereum L1 transactions, existing Ethereum users can use their existing Ethereum keys with their existing wallet software such as Metamask.
Token interoperability. Users can easily transfer their ETH, ERC-20 and ERC-721 tokens between Ethereum and the Arbitrum Rollup chain. As we explain in detail below, it is possible to mint tokens in L2 that can subsequently be withdrawn and recognized by the L1 token contract.
Fast finality. Transactions complete with the same finality time as Ethereum L1 (and it's possible to get faster finality guarantees by trading away trust assumptions; see the Arbitrum Rollup whitepaper for details).
Non-custodial. Arbitrum Rollup is a non-custodial scaling solution, so users control their funds/points and neither Reddit nor anyone else can ever access or revoke points held by users.
Censorship Resistant. Since it's completely decentralized, and the Arbitrum protocol guarantees progress trustlessly, Arbitrum Rollup is just as censorship-proof as Ethereum.
Block explorer. The Arbitrum Rollup block explorer allows users to view and analyze transactions on the Rollup chain.
Limitations
Although this is a bake-off, we're not going to sugar coat anything. Arbitrum Rollup, like any Optimistic Rollup protocol, does have one limitation, and that's the delay on withdrawals.
As for the concrete length of the delay, we've done a good deal of internal modeling and have blogged about this as well. Our current modeling suggests a 3-hour delay is sufficient (but as discussed in the linked post there is a tradeoff space between the length of the challenge period and the size of the validators’ deposit).
Note that this doesn't mean that the chain is delayed for three hours. Arbitrum Rollup supports pipelining of execution, which means that validators can keep building new states even while previous ones are “in the pipeline” for confirmation. As the challenge delays expire for each update, a new state will be confirmed (read more about this here).
So activity and progress on the chain are not delayed by the challenge period. The only thing that's delayed is the consummation of withdrawals. Recall though that any single honest validator knows immediately (at the speed of L1 finality) which state updates are correct and can guarantee that they will eventually be confirmed, so once a valid withdrawal has been requested on-chain, every honest party knows that the withdrawal will definitely happen. There's a natural place here for a liquidity market in which a validator (or someone who trusts a validator) can provide withdrawal loans for a small interest fee. This is a no-risk business for them as they know which withdrawals will be confirmed (and can force their confirmation trustlessly no matter what anyone else does) but are just waiting for on-chain finality.
3. The recipe: How Arbitrum Rollup works
For a description of the technical components of Arbitrum Rollup and how they interact to create a highly scalable protocol with a developer experience that is identical to Ethereum, please refer to the following documents:
Arbitrum Rollup Whitepaper
Arbitrum academic paper (describes a previous version of Arbitrum)
4. Developer docs and APIs
For full details about how to set up and interact with an Arbitrum Rollup chain or validator, please refer to our developer docs, which can be found at https://developer.offchainlabs.com/.
Note that the Arbitrum version described on that site is older and will soon be replaced by the version we are entering in Reddit Bake-Off, which is still undergoing internal testing before public release.
5. Who are the validators?
As with any Layer 2 protocol, advancing the protocol correctly requires at least one validator (sometimes called block producers) that is honest and available. A natural question is: who are the validators?
Recall that the validator set for an Arbitrum chain is open and permissionless; anyone can start or stop validating at will. (A useful analogy is to full nodes on an L1 chain.) But we understand that even though anyone can participate, Reddit may want to guarantee that highly reputable nodes are validating their chain. Reddit may choose to validate the chain themselves and/or hire third-party validators.To this end, we have begun building a marketplace for validator-for-hire services so that dapp developers can outsource validation services to reputable nodes with high up-time. We've announced a partnership in which Chainlink nodes will provide Arbitrum validation services, and we expect to announce more partnerships shortly with other blockchain infrastructure providers.
Although there is no requirement that validators are paid, Arbitrum’s economic model tracks validators’ costs (e.g. amount of computation and storage) and can charge small fees on user transactions, using a gas-type system, to cover those costs. Alternatively, a single party such as Reddit can agree to cover the costs of invited validators.
6. Reddit Contract Support
Since Arbitrum contracts and transactions are byte-for-byte compatible with Ethereum, supporting the Reddit contracts is as simple as launching them on an Arbitrum chain.
Minting. Arbitrum Rollup supports hybrid L1/L2 tokens which can be minted in L2 and then withdrawn onto the L1. An L1 contract at address A can make a special call to the EthBridge which deploys a "buddy contract" to the same address A on an Arbitrum chain. Since it's deployed at the same address, users can know that the L2 contract is the authorized "buddy" of the L1 contract on the Arbitrum chain.
For minting, the L1 contract is a standard ERC-20 contract which mints and burns tokens when requested by the L2 contract. It is paired with an ERC-20 contract in L2 which mints tokens based on whatever programmer provided minting facility is desired and burns tokens when they are withdrawn from the rollup chain. Given this base infrastructure, Arbitrum can support any smart contract based method for minting tokens in L2, and indeed we directly support Reddit's signature/claim based minting in L2.
Batch minting. What's better than a mint cookie? A whole batch! In addition to supporting Reddit’s current minting/claiming scheme, we built a second minting design, which we believe outperforms the signature/claim system in many scenarios.
In the current system, Reddit periodically issues signed statements to users, who then take those statements to the blockchain to claim their tokens. An alternative approach would have Reddit directly submit the list of users/amounts to the blockchain and distribute the tokens to the users without the signature/claim process.
To optimize the cost efficiency of this approach, we designed an application-specific compression scheme to minimize the size of the batch distribution list. We analyzed the data from Reddit's previous distributions and found that the data is highly compressible since token amounts are small and repeated, and addresses appear multiple times. Our function groups transactions by size, and replaces previously-seen addresses with a shorter index value. We wrote client code to compress the data, wrote a Solidity decompressing function, and integrated that function into Reddit’s contract running on Arbitrum.
When we ran the compression function on the previous Reddit distribution data, we found that we could compress batched minting data down to to 11.8 bytes per minting event (averaged over a 6-month trace of Reddit’s historical token grants)compared with roughly 174 bytes of on-chain data needed for the signature claim approach to minting (roughly 43 for an RLP-encoded null transaction + 65 for Reddit's signature + 65 for the user's signature + roughly 8 for the number of Points) .
The relative benefit of the two approaches with respect to on-chain call data cost depends on the percentage of users that will actually claim their tokens on chain. With the above figures, batch minting will be cheaper if roughly 5% of users redeem their claims. We stress that our compression scheme is not Arbitrum-specific and would be beneficial in any general-purpose smart contract platform.
8. Benchmarks and costs
In this section, we give the full costs of operating the Reddit contracts on an Arbitrum Rollup chain including the L1 gas costs for the Rollup chain, the costs of computation and storage for the L2 validators as well as the capital lockup requirements for staking.
Arbitrum Rollup is still on testnet, so we did not run mainnet benchmarks. Instead, we measured the L1 gas cost and L2 workload for Reddit operations on Arbitrum and calculated the total cost assuming current Ethereum gas prices. As noted below in detail, our measurements do not assume that Arbitrum is consuming the entire capacity of Ethereum. We will present the details of our model now, but for full transparency you can also play around with it yourself and adjust the parameters, by copying the spreadsheet found here.
Our cost model is based on measurements of Reddit’s contracts, running unmodified (except for the addition of a batch minting function) on Arbitrum Rollup on top of Ethereum.
On the distribution of transactions and frequency of assertions. Reddit's instructions specify the following minimum parameters that submissions should support:
Over a 5 day period, your scaling PoC should be able to handle:
  • 100,000 point claims (minting & distributing points)
  • 25,000 subscriptions
  • 75,000 one-off points burning
  • 100,000 transfers
We provide the full costs of operating an Arbitrum Rollup chain with this usage under the assumption that tokens are minted or granted to users in batches, but other transactions are uniformly distributed over the 5 day period. Unlike some other submissions, we do not make unrealistic assumptions that all operations can be submitted in enormous batches. We assume that batch minting is done in batches that use only a few percent on an L1 block’s gas, and that other operations come in evenly over time and are submitted in batches, with one batch every five minutes to keep latency reasonable. (Users are probably already waiting for L1 finality, which takes at least that long to achieve.)
We note that assuming that there are only 300,000 transactions that arrive uniformly over the 5 day period will make our benchmark numbers lower, but we believe that this will reflect the true cost of running the system. To see why, say that batches are submitted every five minutes (20 L1 blocks) and there's a fixed overhead of c bytes of calldata per batch, the cost of which will get amortized over all transactions executed in that batch. Assume that each individual transaction adds a marginal cost of t. Lastly assume the capacity of the scaling system is high enough that it can support all of Reddit's 300,000 transactions within a single 20-block batch (i.e. that there is more than c + 300,000*t byes of calldata available in 20 blocks).
Consider what happens if c, the per-batch overhead, is large (which it is in some systems, but not in Arbitrum). In the scenario that transactions actually arrive at the system's capacity and each batch is full, then c gets amortized over 300,000 transactions. But if we assume that the system is not running at capacity--and only receives 300,000 transactions arriving uniformly over 5 days-- then each 20-block assertion will contain about 200 transactions, and thus each transaction will pay a nontrivial cost due to c.
We are aware that other proposals presented scaling numbers assuming that 300,000 transactions arrived at maximum capacity and was executed in a single mega-transaction, but according to our estimates, for at least one such report, this led to a reported gas price that was 2-3 orders of magnitude lower than it would have been assuming uniform arrival. We make more realistic batching assumptions, and we believe Arbitrum compares well when batch sizes are realistic.
Our model. Our cost model includes several sources of cost:
  • L1 gas costs: This is the cost of posting transactions as calldata on the L1 chain, as well as the overhead associated with each batch of transactions, and the L1 cost of settling transactions in the Arbitrum protocol.
  • Validator’s staking costs: In normal operation, one validator will need to be staked. The stake is assumed to be 0.2% of the total value of the chain (which is assumed to be $1 per user who is eligible to claim points). The cost of staking is the interest that could be earned on the money if it were not staked.
  • Validator computation and storage: Every validator must do computation to track the chain’s processing of transactions, and must maintain storage to keep track of the contracts’ EVM storage. The cost of computation and storage are estimated based on measurements, with the dollar cost of resources based on Amazon Web Services pricing.
It’s clear from our modeling that the predominant cost is for L1 calldata. This will probably be true for any plausible rollup-based system.
Our model also shows that Arbitrum can scale to workloads much larger than Reddit’s nominal workload, without exhausting L1 or L2 resources. The scaling bottleneck will ultimately be calldata on the L1 chain. We believe that cost could be reduced substantially if necessary by clever encoding of data. (In our design any compression / decompression of L2 transaction calldata would be done by client software and L2 programs, never by an L1 contract.)
9. Status of Arbitrum Rollup
Arbitrum Rollup is live on Ethereum testnet. All of the code written to date including everything included in the Reddit demo is open source and permissively licensed under the Apache V2 license. The first testnet version of Arbitrum Rollup was released on testnet in February. Our current internal version, which we used to benchmark the Reddit contracts, will be released soon and will be a major upgrade.
Both the Arbitrum design as well as the implementation are heavily audited by independent third parties. The Arbitrum academic paper was published at USENIX Security, a top-tier peer-reviewed academic venue. For the Arbitrum software, we have engaged Trail of Bits for a security audit, which is currently ongoing, and we are committed to have a clean report before launching on Ethereum mainnet.
10. Reddit Universe Arbitrum Rollup Chain
The benchmarks described in this document were all measured using the latest internal build of our software. When we release the new software upgrade publicly we will launch a Reddit Universe Arbitrum Rollup chain as a public demo, which will contain the Reddit contracts as well as a Uniswap instance and a Connext Hub, demonstrating how Community Points can be integrated into third party apps. We will also allow members of the public to dynamically launch ecosystem contracts. We at Offchain Labs will cover the validating costs for the Reddit Universe public demo.
If the folks at Reddit would like to evaluate our software prior to our public demo, please email us at [email protected] and we'd be more than happy to provide early access.
11. Even more scaling: Arbitrum Sidechains
Rollups are an excellent approach to scaling, and we are excited about Arbitrum Rollup which far surpasses Reddit's scaling needs. But looking forward to Reddit's eventual goal of supporting hundreds of millions of users, there will likely come a time when Reddit needs more scaling than any Rollup protocol can provide.
While Rollups greatly reduce costs, they don't break the linear barrier. That is, all transactions have an on-chain footprint (because all calldata must be posted on-chain), albeit a far smaller one than on native Ethereum, and the L1 limitations end up being the bottleneck for capacity and cost. Since Ethereum has limited capacity, this linear use of on-chain resources means that costs will eventually increase superlinearly with traffic.
The good news is that we at Offchain Labs have a solution in our roadmap that can satisfy this extreme-scaling setting as well: Arbitrum AnyTrust Sidechains. Arbitrum Sidechains are similar to Arbitrum Rollup, but deviate in that they name a permissioned set of validators. When a chain’s validators agree off-chain, they can greatly reduce the on-chain footprint of the protocol and require almost no data to be put on-chain. When validators can't reach unanimous agreement off-chain, the protocol reverts to Arbitrum Rollup. Technically, Arbitrum Sidechains can be viewed as a hybrid between state channels and Rollup, switching back and forth as necessary, and combining the performance and cost that state channels can achieve in the optimistic case, with the robustness of Rollup in other cases. The core technical challenge is how to switch seamlessly between modes and how to guarantee that security is maintained throughout.
Arbitrum Sidechains break through this linear barrier, while still maintaining a high level of security and decentralization. Arbitrum Sidechains provide the AnyTrust guarantee, which says that as long as any one validator is honest and available (even if you don't know which one will be), the L2 chain is guaranteed to execute correctly according to its code and guaranteed to make progress. Unlike in a state channel, offchain progress does not require unanimous consent, and liveness is preserved as long as there is a single honest validator.
Note that the trust model for Arbitrum Sidechains is much stronger than for typical BFT-style chains which introduce a consensus "voting" protocols among a small permissioned group of validators. BFT-based protocols require a supermajority (more than 2/3) of validators to agree. In Arbitrum Sidechains, by contrast, all you need is a single honest validator to achieve guaranteed correctness and progress. Notice that in Arbitrum adding validators strictly increases security since the AnyTrust guarantee provides correctness as long as any one validator is honest and available. By contrast, in BFT-style protocols, adding nodes can be dangerous as a coalition of dishonest nodes can break the protocol.
Like Arbitrum Rollup, the developer and user experiences for Arbitrum Sidechains will be identical to that of Ethereum. Reddit would be able to choose a large and diverse set of validators, and all that they would need to guarantee to break through the scaling barrier is that a single one of them will remain honest.
We hope to have Arbitrum Sidechains in production in early 2021, and thus when Reddit reaches the scale that surpasses the capacity of Rollups, Arbitrum Sidechains will be waiting and ready to help.
While the idea to switch between channels and Rollup to get the best of both worlds is conceptually simple, getting the details right and making sure that the switch does not introduce any attack vectors is highly non-trivial and has been the subject of years of our research (indeed, we were working on this design for years before the term Rollup was even coined).
12. How Arbitrum compares
We include a comparison to several other categories as well as specific projects when appropriate. and explain why we believe that Arbitrum is best suited for Reddit's purposes. We focus our attention on other Ethereum projects.
Payment only Rollups. Compared to Arbitrum Rollup, ZK-Rollups and other Rollups that only support token transfers have several disadvantages:
  • As outlined throughout the proposal, we believe that the entire draw of Ethereum is in its rich smart contracts support which is simply not achievable with today's zero-knowledge proof technology. Indeed, scaling with a ZK-Rollup will add friction to the deployment of smart contracts that interact with Community Points as users will have to withdraw their coins from the ZK-Rollup and transfer them to a smart contract system (like Arbitrum). The community will be best served if Reddit builds on a platform that has built-in, frictionless smart-contract support.
  • All other Rollup protocols of which we are aware employ a centralized operator. While it's true that users retain custody of their coins, the centralized operator can often profit from censoring, reordering, or delaying transactions. A common misconception is that since they're non-custodial protocols, a centralized sequencer does not pose a risk but this is incorrect as the sequencer can wreak havoc or shake down users for side payments without directly stealing funds.
  • Sidechain type protocols can eliminate some of these issues, but they are not trustless. Instead, they require trust in some quorum of a committee, often requiring two-third of the committee to be honest, compared to rollup protocols like Arbitrum that require only a single honest party. In addition, not all sidechain type protocols have committees that are diverse, or even non-centralized, in practice.
  • Plasma-style protocols have a centralized operator and do not support general smart contracts.
13. Concluding Remarks
While it's ultimately up to the judges’ palate, we believe that Arbitrum Rollup is the bakeoff choice that Reddit kneads. We far surpass Reddit's specified workload requirement at present, have much room to optimize Arbitrum Rollup in the near term, and have a clear path to get Reddit to hundreds of millions of users. Furthermore, we are the only project that gives developers and users the identical interface as the Ethereum blockchain and is fully interoperable and tooling-compatible, and we do this all without any new trust assumptions or centralized components.
But no matter how the cookie crumbles, we're glad to have participated in this bake-off and we thank you for your consideration.
