A ponzi is when an investment that supposedly produces a return actually pays the funds needed to deliver that return from new entrants to the scheme rather than productive enterprise.
Given that there’s literally no productive return-producing enterprise underpinning any of this it’s totally fine to consider the word ponzi at least loosely applicable to the entire concept of cryptocurrency as practiced.

By this definition most crypto wouldn‘t be a ponzi.
E.g. bitcoin doesn‘t claim that funds are invested in productive entreprise.
It is clear that it is only a value store (like gold). Whether it is any good at storing value long term, we will see.

Bitcoin proponents definitely (for a time) claimed that it was Bitcoin's utility as a currency that gave it value in the first place. That everyone would need some because everyone would use it to transact. That's a claim of an inherent investment value that didn't actually exist, making Bitcoin exactly like a distributed Ponzi scheme.

It was originally created to be a form of non-fiat democratized currency. It is exactly that even though it's not its most popular use which is as a store of value. I don't see how that makes it a Ponzi scheme. I buy things with it a few times per year and do my degenerate sports gambling with it all the time. It works within seconds for almost no cost.
