Getting a 84% risk bitcoin from mixer is stupid and dangerous!!! You can do nothing with it. If you send it to any other service (except for another mixer) you will loose your money and get banned.
You should read more about tainted coins. After you mix your coin with anonymity set with Coinjoin transactions, how you use your outputs will decide your coins are tainted or not tainted.
Bitcoin Q&A: Blacklists, Taint, and Wallet Finger-printing.
Hello, as you could see our algorithm works on the basis of coinjoin. This technique does not reduce the AML score every time and it is almost impossible to predict that it will be. The coinjoin is useful to make the origin of your funds difficult to trace since they are mixed with others.
We do not recommend sending these funds directly to a centralized exchange. If your goal is to lower your AML score you can try our advanced method.
After mixing and get outputs, users can move their bitcoins to their another wallet and repeat it a few rounds. Don't move it with round number and use change address. Exchanges don't trace origin of coins too deep in blockchain history.
In addition, they can use non-KYC exchanges before moving their coins to KYC exchanges.
