Hey, even I called that one--didn't even need to consult TF. Do the math. Six percent monthly return means 72% annual return. And that's not counting all the extra bonuses from affiliate referrals. Who pays out that kind of "interest" rate? If they're seriously making that much money off of their "investing" then what do they need to pay us for?
I will say that I am making some money off them. They're running a slick marketing campaign on BitVisitor and CoinAd and I'm more than happy to collect earnings from viewing their site. But I'll invest those earnings somewhere else, thank you.
Be careful out there. Watch out for scams!
