My rates for hosting start at 8.75 cents USD/kWh, including all taxes and fees.
not optimal , but there is still profit to be made with that rate, $3.35 -1.236, so a little above 2 dollars per day
1.236 = with 14.160 kw/h per day(590 x 24/1k) and 0.0875 per kw, we are looking at $1.236 cost per day
I agree there is still some profit left at that rate. I just with "Lowest-Cost Miner Hosting:" as advertised was even cheaper.
If somewhere in the US can do 6 cent's or so I think they would find a LOT of business. But so far no one has gone to that extent.
