I think it's a bit pointless to argue about whether cryptocurrencies are Ponzi schemes or not. What I would say is that most cryptocurrencies have no fundamental value, and are therefore bubbles. I don't know what the term is for when someone deliberately creates an asset bubble with the intention of profiting from it. It's something like a very long-form, deliberative pump-and-dump.
