Looking forward to the response the author of this topic. I really wonder where did his $ 850 and whether he could return them.
It seems he got scammed and as we know once you lose control of your coins then it is impossible to recover them, I am sorry for the OP and this should not happen but we must be alert because this is becoming more common, scammers are realizing that as crypto becomes more popular the average users knows less and less about computers so they are easier to scam.
