Yes it might be profitable at $0.10/kwh but to what extent?
When 80% of all your profit is going to electricity is it really worth mining?
I did the calculation and most have the RX 470/570 which uses like 130 Watts so at $0.10/kwh you make about $0.12/day.
However after fees, bank fees, errors, GPU downtime, etc you probably end up making a nickel per GPU. Is it really worth mining for that much?
this essentially sums it up, & this number will vary for everyone but at some point it simply does not make sense to invest the time and money into mining --- For many it is still a lucrative endeavor, or perhaps speculation mining is allowing you to still do very well --- however the overall bad health of crypto mining profitability cannot be ignored.
