Well you just need to be more careful. Of course we can talk about the anonymity of crypto casinos, where there is no kyc, because you really do not leave your data. But let’s not forget about crypto wallets, many of which have kyc. When I first decided to play in a live bitcoin casino, I had exactly such a crypto wallet, and it immediately removes anonymity. Or if crypto was bought on an exchange where you passed kyc, and the wallet is directly connected to the player’s account, transactions can be tracked.
