• This is a nice interview of UC-Berkeley computer researcher Nicholas Weaver in Current Affairs.  He does a pointedly humorous takedown of what he labels “a giant self-assembled Ponzi scheme. You hear about people making money in Bitcoin or cryptocurrency. They only make money because some other sucker lost more.


So the stock market and the bond market are a positive-sum game. There are more winners than losers. Cryptocurrency starts with zero-sum. So it starts with a world where there can be no more winning than losing. We have systems like this. It’s called the horse track. It’s called the casino. Cryptocurrency investing is really provably gambling in an economic sense. And then there’s designs where those power bills have to get paid somewhere. So instead of zero-sum, it becomes deeply negative-sum.

Effectively, then, the economic analogies are gambling and a Ponzi scheme. Because the profits that are given to the early investors are literally taken from the later investors. This is why I call the space overall, a “self-assembled” Ponzi scheme. There’s been no intent to make a Ponzi scheme. But due to its nature, that is the only thing it can be.
