The common method of money laundering is to spend and lose, but in fact, the other party is also controlled by itself or itself. For example, in the futures market, if you open an account A and an account B with legal income and illegal income (the name is not yours) respectively, and go long and short at the same price, then A's profit is also B's loss, and then close the position at the same time, the black money will be washed white and legal, because it seems that account A earns market money and has nothing to do with B.

Of course, it doesn't matter if, unfortunately, because of the operation of others in the futures market, A loses to B, but the white is washed to black, and it is still its own. I have to start all over again and do it a few more times. I will always succeed.
