There are plenty of sane people who use Bitcoin as a currency. Making blithe moral declarations like this doesn't spark curiosity and is incredibly tired after so many years (you're not the first).

"Unsound ponzi scheme" could just as well be applied to any fiat currency. It has all the same rules (early entrants are more privileged in "the game" and can invest to out-perform younger players). It is very odd to hear people applying such qualitative judgments like this when the alternative is a currency that is actively debased by its issuers. Or do you think the inflation we've all suffered under isn't a problem?
