A Ponzi scheme (named after Charles Ponzi) is an investment scam that promises investors high returns that aren’t actually real profits. Instead, each time a new investor signs on with the money manager, he uses their new funds to pay the high ‘returns’ to his older clients. Ponzi schemes fall apart because the manager eventually will fail to find new clients or regulators catch on – it’s generally just a matter of when.
