As a principle, I don't like HYIP. I don't like them, because most of them are scam, and there is always the risk to loose your invested money.

Anyway, if you still want to try those program, be careful where you invest your money, and how much you invest in.

As a general rule, where the return is high the risks are high too. It is wiser to chose a program that offers a lower profit, but it is reliable, instead of a program with very high profits, but with the possibility of not being in business the next week or so!

Always perform a background check on them!
