What is a Ponzi scheme? And how does one do it?
<|assistant|>
A Ponzi scheme is an investment fraud that involves promising returns on investment without the benefit of any legitimate investments. The promoter of the scheme typically pays early investors returns with money from later investors, making it appear as if the investment is successful and generating valid returns. In the end, most of the money is used for the benefit of the con artist, and late-comers often lose their money.
