i personally know people that have bought shares and cashed them out after the 120 days. and coupled with the fact that i havent had a single issue with withdrawing funds daily... the question is... how long do you have to wait before you consider it "legit"?
It's a ponzi today and it will still be a ponzi tomorrow, so never. Unless they drastically reduce the payouts they will fold this year or the next, though. Madoff only paid about 10%/year, which is part of the reason why his ponzi lasted for so long.
