HYIP or better known as High Yield Investment Programme is an investment programme normally offered in the Internet. These investment programmes offer promising high returns. However, many of these sites often turn out to be scams – with many sites shutdown no longer than one to three years in operation. HYIPs usually accept e-gold, e-bullion, INTGold, and StormPay.

HYIPs typically claim to offer interest rates of 1% or more per day on invested funds; some claim to offer much higher daily rates exceeding 200% a day. The highest HYIP on record has offered 1,100% ROI in one day.

The following is a list of HYIP scams that are currently under investigation or have been successfully indicted in a court of law.
