just posted from the source at the bottom that even if you’re not involved in crime, you could still get hit if the BTC you hold was once linked to scams, hacks, or mixers. Regulators and exchanges are now tracking harder, coins can get flagged or even frozen.
Don't keep your coins in an exchange and don't waste time to transfer your funds from an exchange to your noncustodial wallet after the purchase of your bitcoin from p2p trader if you are the type that buy bitcoin regularly. If you receive any funds into your wallet that you don't know the sender, freeze the coins and transfer all your funds to a different wallet which you created for that purpose.
Government cannot freeze your coins when they're in your noncustodial wallet.
