This seems like a very good idea, but I am not sure if it would be considered a pyramid scheme which is illegal. User signs up and pays a dollar. Referer and referer of that referer get 10¢ each. I get the remaining amount. Up to 9 levels. Also users can upgrade and earn double up to 90¢. So is it legal?
Hard to tell. Depends on country and laws if its legal. But I can tell you its stupid and a waste of time.
If the only source of money is new members joining in, and you don't even pretend to sell a product or service, I believe you have what's called the "Ponzi Scheme" flavor of pyramid scheme.

I'm still going to do it. It sounds to me like ponzi is a scam, and I'm not making any false claims. If I get any notices from the gov't, I will shut it down.
