It's kind of concerning to be honest.
For example, the major BINANCE hack that saw like $320m of BTC being stolen. This *can* be traced on the blockchain, because it's transparent and records all txns.
Thus, if somehow, you ended up with *some* 'dirty' bitcoins, and you tried to move it to a CEX like Coinbase, then it's highly likely those "coins" would be sanctioned on arrival.
Unlike money, BTC carries its history.

Coinjoins help by adding deniability
yeah, so does 'mixers'
I mean, people find a way I guess. But it's still "traceable" via the blockchain itself.
I suppose it's really about putting as many txn between you and the coins, then also not using KYC CEX
