Well i have seen all kinds of scam in internet, i feel disgusted every time as i might be wrong i can be right. I can tell that you are also one of them and this way been on forex also where some scammers pretend to be legit monitors and wallet traders they ask to manage your account with a percentage of profit fees. What they do is to trade reverse position on both their victim wallets for example the first wallet they open a buy position on eurusd pair with high lot and the other victim’s wallet they open a sell position. So it’s official one of them will double his capital money and the other will blow it all
The same as you can do. Give reverse prediction for two clients and the winner will pay you a percentage of the winning. I might be wrong but you should provide evidence
