1 - get a Monero wallet (feather or mymonero)
2- get the tor browser
3- Swap your bitcoin for Monero (XMR). The best no-kyc exchange I think is xchange.me, they only charge 1%. They have a great tor website. Navigate here with your tor browser:

4- Once you get the monero, movie it to a second monero address.
Because of how Monero works, your crypto is now fully anonymous. You can now swap it back for bitcoin or any other crypto, and your coins are untraceable.
This is the right answer. Use a good no-kyc exchange like xchange over tor, rinse and repeat.
The good old one two switcharu! Monero was banned for any approved ransomeware payments some years ago by OFAC - it’s funny because threat actors will still demand ransoms paid out in Monero but it’s actually illegal to pay a legal ransom that has been negotiated by Incident Response firms and threat actors simply because it is untraceable.
