The inverment online

Just of recent, i started seeing differnt kind of site promising differnt kind of percentage on some deposit to theri site. I rush to take part with two of that kind. One pay the other did not pay, but i don't trust any of this there promising or how do u feel. At time if u see what they promise u wonder how they are going to get the money to pay. If u have come accross on of this kind of site, have u found u believe will pay?. It clear to me now that that is not the best place to keep my money. But there another way of making money that people do talk about. i don't if any body can say anything to it. A talkng of forex trade. who no anyting about it. His possible i can get expert to manage my money for tin the business. if that is true, like how much can start with, what amount does the expert will be atking out of my money.
