I have gotten payouts, i upgraded to v 1.1 and it has payed for itself like 5x so, its free if u want a few free .005 btc every few weeks (minimum withdraw is .005 and it takes ahwhile to get there, u get 40 sat a minute for free) , if u upgrade u get alot more.
I know that site ,i requested for a payout but until now still pending. It wants me first to upgrade ti v.1.1 in order for ny withdrawal to be sent. Some membets already said that its a scam, so beware
