I think you should review your site ponzi. It's really not good for invesment.
You also think about a opportunity cost if someone intented to invest into your site.
Not a ponzi.
Denying the fact a hundred times does not make it any more legit.
You can use a different name for whatever it is - you can call it
- Investor-based scheme
- Pyramid scheme
- Gambling
-
But in the end the fact remains same - old investors get paid from new investor's money.
IT IS A PONZI.
