I can't say one way or the other if this is a ponzu, but here are my results over the last 5 months. I've cashed out and received in my wallet 4 shares, plus about 75% . I reinvested 2 shares and kept the rest as profit. One of the tricks to not getting trapped, is to realize you're in a trap...
Basically I say don't risk what you don't want to lose, and don't get greedy and keep rolling over your investment.
Good luck,
Jack
