What do you guys think separates the crypto situation now from bubbles like the dotcom bubble back in 2000? I find there are a lot of similarities, and it worries me. The expansion of the crypto markets with new altcoins and ICO's coming every day, it seems as if sooner or later it's going to have to stop. What gives all these coins their value?
Maybe, optimism of their owners?
I guess you say it correctly further in your post that in the majority of cases where "new altcoins and ICO's are coming every [other] day", we have what you call "a ponzi financed economy" (though I don't know anything about Minsky's crisis model). That said, I think we should still distinguish between Bitcoin as well as a few other altcoins which seriously aim at being used as a means of payment (i.e. as money) and altcoins which are created for the single purpose of stealing money. In other words, even if it is really a sort of ponzi financed economy, this doesn't mean there are no worthy assets which might have a future like it happened with the dotcom bubble. The majority of scams died out eventually back then but legitimate companies with real stuff behind them survived
