Hello! I've always had a interest in Mining, so I was wondering what a good $ per KWH is. In my area I pay a little above $0.07.
What do you pay? What's the best price for profitable mining?
The best price is definitively "free" electricity(of course). But for operation where you have to pay by kWh, a good price is 0.03USD~/kWh.
You probably don't need that low to ROI on a proper purchase, but keep in mind that's what you're competing with.
