A high-yield investment program (HYIP) is a type of Ponzi scheme, an investment scam that promises unsustainably high return on investment by paying previous investors with the money invested by new investors.
This said. HYIP's remain popular with participants "investing" knowing that it is a Pyramid scheme. They are constantly on the look out for new HYIP's because the the earlier they can get in the better. The trick is to find new ones asap and get out asap. Making a quick return before it goes bust. Then look for another new one.
These "investors" make big bucks and even have a forum to chat about HYIP's and give tips on any new ones available. Getting in too late
will will make you vulnerable to a loss.
These professional HYIP investors make a living off these. A 100% in 3 months is not to be scoffed at.
Not for me though.
