That's inaccurate.
Most fiat currencies today are characterized with the same elements as those of ponzi schemes, its slower over time, but nevertheless it is the same elements with the central bank printing money from nothing.
Crypto can be suborned into any existing ponzi scheme easily by allowing exchanges of these fiat assets and leverage from any of those fiat systems.
Those crypto systems which have ballooned as a result of that would then accurately and appropriately be considered ponzi schemes, even though its just a small leg of the entire ponzi scheme.
There is no effective way for an individual to tell inflows and outflows from the system, and any financial banker is aware of frauds that can create the illusion of price action through the use of leverage, and collusive wash-sale contracts (similar to options). That is how gold and metals commodities are largely suppressed.
Without visibility, those frauds don't come to light, but visibility is a tradeoff when it comes to privacy, especially in 0 trust environments.
Edit: If you are going to downvote, at least do the courtesy of explaining why. If you do not, it simply looks like some brainless person using a bot is trying to censor people, and any intelligent reader will see that for what it actually is. Put another way, use your words, or look like a shill.
