You can make money on a real ponzi. This sounds like a pure and simple scam.
I made 6k off of 12Daily pro. 12% daily payout. Make a few bucks in Dad and Daves ponzi. Lost a free buck in Feeder Fund. This was a few years ago, when ponzi scams actually paid out. The key is to get in early and get out early.
