hey, i have just created this account to give my honest opinion about this site. I got referred by a friend who tried this site "Btc2Double" and he really got his payout... i gave it a try too with just 0.03 btc and i got a payment of 0.06 btc sent to my blockchain wallet.
I don't know if i got luck or not, but right now i can't say nothing bad about them, i'm very happy right now!
