Though forex is a risky trading business, big capital is always friendly with professional traders. For example if a trader invests 100 $ and if his average earnings 25%, then his income would be 25 $. But if he invests 250 $ and makes a 20% lower profit, then his earnings will be 50 $. And he will be able to make the most of it by using where he can produce better results. That's why I think that big capital is friendly with professionals.
