Just a simple question , how much should be the hash rate of the RX 580 ? My brother is mining with 3 Riggs with nicehash and the return is 3 $ per day so 1$ for each rigg , I think the hash rate is very low in this case or is it normal , could you please tell me more about your statistics , in which pool you're mining and your ROI .
One rx580 rig (x6 rx580's) should get you 180 mh/s on ethash. 3 dollars a day for 3 rigs doing 180 mh/s is not right
