I'm not sure about this, cuz im new into bitcoin, but this is the first site i have been receiving payments... for months, i got 0.21 btc profit, and i exchanged that to my local currency, I just bought a Nintendo 3ds xl lol. I don't truly know how this site works, but ITS PAYING SINCE MARCH, i don't even think its a ponzi, tried a few ponzis like robitbot and some doublers and got scammed a few bucks, but this site is different as hell. IT PAYS, slowly but it does. Reinvested 0.01 now
