I have never read so much about nothing as I have when reading about some new coin. It's worse than a pyramid scheme. At least there, you end up with a decade-worth of skin cream.
You're talking about multi-level marketing. Which isn't quite a pyramid scheme (even though it is pyramid-ish). Pyramid Schemes have the originators (the "top" of the pyramid) win lots of money, while the base (the "bottom" of the pyramid, where most people are) losers. And the top barely did any work to get there: they just took the money from people below them.
On a forum I used many years ago a regular was forever pushing an MLM and I investigated how it worked, just to try to understand how screwed he was rather than out of any misunderstanding that MLMs are a good idea.
It was one of those health juice MLMs, and what I realised was very clever was that the business structure was set up so as to on the one hand make it less obviously an MLM, and then on the other hand ensure the scammers were insulated from the scam.
There's a pretty ordinary over-complicated compensation package, with tiers of distributors getting a percentage from those beneath them in a structure that sure looks like a pyramid - and imaginary "consumers" who buy at the supposed retail prices at the bottom of the pyramid. But the juice itself is bought exclusively from a separate company at an inflated price.
If the government shuts down the MLM company, few there were getting rich, it's just a handful of people out of an office somewhere. The big money flows into the juice manufacturer selling this awful tasting muck - and they can claim they know nothing about any pyramid scheme. Selling cheap juice for lots of money isn't a crime it's just capitalism.
