Suggestions and corrections about my site are welcome and often get incorporated into the site. Thanks for all of the positive comments, and those few corrections.
I have had a number of requests from academic types, and other authors, asking permission to include this in course materials, which I grant as long as they credit me (You still have to ask, though).
I get a lot of questions from people who are wondering if some investment is a Ponzi scheme. Sorry, but I have only taken the time to research Charles Ponzi; I don't make pronouncements on other schemes. I do hope that reading about this one Ponzi Scheme helps people to be skeptical and use their own judgement when they think an investment or sales scheme may not have a sound financial foundation.
Another common question is do I have a Ponzi coupon myself? Regrettably, I do not. If anybody does, I would love to discuss buying it or getting a copy.
