I trade forex and from my own experience and other forex traders,money managers and hedgefund managers whom i talk to every day and we share ideas about trades.No one is sure they will make money.only 5% make money in forex while 95% LOSE.You cannot always be the 5%.These guys should have promised a lower and attainable return like 10-30% which i give to my net worth individuals(of 1millionusd portfolio).
