Well, try it. They promise profit in 48 hours at most. If you can get your money out, then it's just a Ponzi scheme that hasn't collapsed yet. If you cannot (e.g., if the transaction simply doesn't work or they start coming with all sorts of reasons why it can't be done "right now" and you "have to invest more"), then it's a simple scam and you'll never see your money.
I wish you luck.
