I can't be the only one who's not hot on crypto. Do we really want a world where even the simplest transaction is permanently recorded publicly and cryptographically sealed? The governments will just mandate custodial wallets and we'll be back in the same place with respect to things like forfeitability.

I still don't understand this argument, maybe because I just don't understand enough about crypto currency itself.

What coin is stable enough to use as currency? Unless OnlyFans could pay its employees and services with that said coin (who could then use it elsewhere directly), the company would still have to convert to fiat currency right? And wouldn't that itself affect the coin price?

I am very much a cryptocurrency skeptic, but you could imagine a token which is only used as a medium of exchange. I.e. you convert your USD into the token immediately before making the payment, and the recipient converts it back to USD milliseconds later.
