if i have a rig of 5 AMD cards each of 30 mh/s
mining etherium
how much etherium i can find at the end of the month ?
right now, for electricity at 0.12 USD / kwH you would be barely breaking even, even when undervolting and optimizing massively with Rx580's,
if you still want to be profitable gpu mining ETH at the moment, you need a location with 5-6 cents electricity rates / kwH...
regardless, you would be now looking to mine roughly 0.30 ETH / month with that setup...
