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.
Are you talking about BTC prominer and bitminer.io? So they actually pay. I thought that they were a scam site that never really pay. because its just too good to be true. 40 satoshi for everyminute and 0.0006 per day. Maybe i will try that again.
