While this is true, there are still those who do not yet require KYC with a daily withdrawal limit. Taking this into account, it is possible to send BTC anonymously to CEX if we make them anonymous in some way before that, and then sell/exchange them there for another coin. However, the whole thing would not make sense if, after all, we sold that BTC and withdrew the fiat to our bank account.

Of course, there are opportunities to hide identities even when it comes to banks, but this is something that still requires additional investment in the form of anonymous bank cards. I'm not talking about something illegal in the literal sense of the word, perhaps rather morally questionable - I think you know exactly what I mean
