i make ALWAYS at least 0.015 a day per rig some times 0.02 when the value increase in all coin, it's very profitable because a single 1070 is making $200 a month or so, there was a similar profit back with ETH mining when it was released at first
Does it mean the ROI for the 1070 is less than 2 months?
yeah precisely if you get it used or second hand, you pay $300 for one, and with $200 a month for each gpu you roi in 1.5 month at worse, this is very good tiem in crypto trust me
