1. The Ponzi Scheme

If current events have proven anything, it’s that there is no more potentially profitable con game than the Ponzi scheme. The trick dates back hundreds of years, but it was popularized by Charles Ponzi, an Italian immigrant to the U.S. who swindled investors out of millions in the early 1900s before being arrested. The modern Ponzi scheme is a form of investment fraud in which a fake or corrupt stockbroker uses the money of his new investors to pay the imaginary returns of his old ones. Initial investments with the fake broker might yield enormous returns for the people being conned, but in reality their money has not been invested in anything–the con man has simply been putting it all into a bank account. Any time someone wants to withdraw money, or if he has to pay the returns of his old investors, the con man simply uses the money he’s gotten from new investors to do it. Nothing is actually being invested, won, or lost in the market. The con man is simply giving that impression so that people keep handing over more and more cash. Because it can only grow so far, any Ponzi scheme is destined to eventually collapse under its own weight, so the con man usually pulls a disappearing act after collecting enough money, leaving the investors with nothing but the fake returns they received to keep them involved in the swindle. Undoubtedly the most famous recent example involved Bernard Madoff, a New York financier who engineered a Ponzi scheme estimated to be in the neighborhood of $65 billion. Madoff was eventually caught and sentenced to 150 years in prison, but not before pulling of what is essentially the biggest con game of all time.
