Many people associate Ponzi schemes with pyramid schemes. While they do share some similarities, they're not exactly the same. If you think about the organization and methodology behind a Ponzi scheme, it certainly has a triangular structure. The schemer sits at the top, above continually increasing rungs of investors. However, there are fundamental differences between how classic pyramid schemes are carried out and how Ponzi schemes are executed.
The essential difference between a pyramid scheme and a Ponzi scheme is that a Ponzi schemer will only ask you to invest in something. You won't be asked to take any more action than handing over money. He or she will claim to take care of the rest and give you your returns later. The Ponzi schemer is the mastermind behind the whole system and is always shuffling money from one place to another.
On the other hand, a pyramid schemer will offer you an opportunity to make the money yourself. It requires more work, though: You have to buy the right to start a franchise and start recruiting more people like yourself. The recruits will often pay the recruiter a cut of their profits. You can read How Pyramid Schemes Work to understand more about that process.
The difference may seem slight, but one point to keep in mind is that unlike pyramid schemes, Ponzi schemes are always illegal [source: Walsh]. Some legitimate businesses, such as Mary Kay and The Pampered Chef, have been built around the pyramid idea. But the nature of a Ponzi scheme necessarily relies on securities fraud. It involves deceit to convince someone to invest money that won't actually be invested.
Nevertheless, some people continue to use the terms interchangeably, and many texts classify Ponzi schemes as a type of pyramid scheme. And, of course, when you're the victim of one, the difference probably seems insignificant.
Next, we'll take a look at some other real-life Ponzi schemers.
