NASA - Ponzi Scheme

A Ponzi scheme (/ˈpɒnzi/, Italian: [ˈpontsi]) is a form of fraud that lures investors and pays profits to earlier investors with funds from more recent investors.[1] Named after Italian businessman Charles Ponzi, the scheme leads victims to believe that profits are coming from legitimate business activity (e.g., product sales or successful investments), and they remain unaware that other investors are the source of funds. A Ponzi scheme can maintain the illusion of a sustainable business as long as new investors contribute new funds, and as long as most of the investors do not demand full repayment and still believe in the non-existent assets they are purported to own.
