A ponzi scheme is a fraudulent investment operation that involves paying returns to investors out of the money raised from new investors.

The scheme is named after Charles Ponzi, an Italian immigrant to the United States in the 1920s.

Remember that new HYIP that I found that pays 25% a month? Well it paid for three months and then it collapsed.
