Many people do not understand the difference between a Pyramid Scheme and a Ponzi Scheme. They are very different. I believe the confusion lies mainly in that they are both Schemes and they both begin with P. A pyramid scheme depends on the idea that you buy into something, but only get paid out when you convince other people to buy in under you or from you. Thus, you have a pyramidal structure. You sell to 10 people, they each sell to 10 people (100 total), and they each sell to 10 people (1000 total), and so on. Usually, the item sold is nothing substantial. This quickly becomes unsustainable, so the last suckers to join cannot sell to anyone else, so their money loses out and trickles up the pyramid. A ponzi scheme is an investment vehicle that promises large returns. For example, I could tell you that I have a brilliant currency arbitrage. Instead of actually earning real returns, though, I convince new investors to invest new money. I use that money to pretend I have returns to the older investors. But now, I have to start earning returns for the new investors. However, that's easy to do because I can advertise huge returns and the old investors can vouch for me that I'm legitimate. Therefore, it's easy to convince new investors to come in with more money so I can keep pretending to have high returns. Usually, ponzi schemes are broken up by the government when they get too big, according to wikipedia. I guess they are also similar in that they involve money and are not infinitely sustainable in that eventually you run out of suckers. But that's the definition of a scheme. Otherwise, it would be a legitimate investment since it would provide returns forever.
