I'm aware of what it says. Realize that the Treasury was producing legal tender in the USA for centuries before Ponzi had a brilliant idea how to exploit people.
None of the ICOs have reached full maturity yet. The oldest isn't even a decade old. We've already seen a number of schemes that drain people's cryptocurrency wallets. More will come. Will any reach the scale of Ponzi's scheme? I think we'll find out when ICOs reach full maturity.
Ponzi was never a market, by the way. That said, cryptocurrencies possess a lot of features of a Ponzi scheme. It's hugely unregulated (#3), people that participate in the market aren't licensed (#4), there's issues with liquidity when exchanges get hammered (#6), and because it's entirely speculative there's high returns with little risk so long as you hold long enough (#1).
