This is why fiat would be dangerous at the same method as crypto as well. Because if you stole crypto then it would be bad and you could be caught,
the question now is that how do we differenciate the bitcoin stolen from the one that is not, we could obviously see many whales around making huge transactions of their coins as its vividly seen on blockchain, but the only privacy is security those whales can have over AML challenges is when they don't make use of centralized exchanges in which i believe they understand this and why as well, i think theft in bitcoin or cryptocurrency has been minimize to the lowest extent compared to fiat only if the bearer is mindful of the security consciousness of his wallet keys and other Phishing kinds of malicious attacks that could lead to hacking, else stolen funds should be individuals responsibility for failure to safeguard their coins.
but if you didn't steal the money, someone else did, then you should feel fine about the crypto in your account.
even if you didn't steal any crypto but uses centralized exchange you're not safe, at any point in time one can be bursted, its either the government demand for the user privacy data or the exchange got hacked and loose it's data and assets, Satoshi will not be responsible for any lost in such manner neither will the exchange pay back your coins, we advise to always use decentralized exchange and if needs be for a centralized one, just little part of your assets should be in CEX.
