Usually I don't trust any HYIP programs. But just to experience it, I tried with some HYIP sites. For the last 15 days, I was scammed around $23, and my profit is just $7. That means I lost around $16 within 15 days from HYIP programs. That seems we really can't earn profit from them. But I think it's upon luck because some people say they have earned good amount from them.
