Using digital money (fiat or non anonymoized crypto) exposes you. you can not be part of a legal business without doing that except accepting real coins, and even then you have fingerprints on it, or maybe they can scan the banknote id and trace that to an ATM, and so on. The only way to be absolute anonymous is stealing some hardware and trying to get it anonymously into some kind of infrastructure you dont own.
