How credible are High-Yield Investment Programs?

All ponzi schemes. Unless you want to loose more money than you put in, forget them.

They are all "SCAMS" don't waste your time and money on such ventures no one ever earn any money from them they all go belly soon or later when people catch on and stop paying into the system. ......

HYIP are high risk investments so they are taking a risk with your money that you invest in them but for that risk they will often if successful in the gamble have a high payout with them. So it isn't really a question of are they credible but are they good at taking the risk and giving a good payout without getting burnt on an investment. These are generally investments in some of the following all markets-stocks, foreign currencies, ETFs, e-Minis, and mutual funds. I don't deal with these as they are high risk of being scams that will at some point collapse leaving people high and dry with no money to their names. http://en.wikipedia.org/wiki/Cherry_Shares http://en.wikipedia.org/wiki/High-yield_investment_program

Most of them are not credible. Almost 99% of High Yield Investment Programs are scams and not credible. Then can go bust anytime. The challenge for you is to learn how to time them. Perfect timing is needed. You must know when to get in and when to get out.

hyips are not a stable way to earn online. I would say these are one of the most riskiest ways to earn online. If you decide to do this only do what you can afford to lose. Never more than that. Also I think Cherryshares and orbistrends are having some technical difficulty right now or they are down.
