Mixes bitcoins and then send to a centralized exchange. When his account is blocked, goes ahead to blame Yomix for putting him on FBI watch list. Who does that?
What was the point of mixing coins then if you were going to send them to a centralized exchange them?

OP, I don't know how long you have used crypto, but you have no one else to blame but yourself. If you want complete privacy and custody of your funds, then avoid centralized exchanges. Simple as that.
