Anyone must be very careful in joining this kind of scheme. The internet nowadays is crowded with scam sites. High-yield investment (HYIP) is a kind of Ponzi scheme. It has an interest of 10-50% or sometimes doubled in a short period of time. The investor will only be paid when there are new members joined and invested.
People said, you have to understand the risk when you join a program like this. Invest only what you can afford to lose. However, my advise is to stop putting in your hard-earned money in any high yield investment company. I bet 99.9% HYIP are scam. Find something on the internet where you can make real money. They are hard to find, but they are real.
