Electricity including maintenance is RMB 0.3 or USD 0.045 per kWh.
So I would pay electricity fee USD 0.045 per kWh. Am I correct that the miner is 0.115 kW per THs? In this case I would pay per day:
1) 13.5*0.115*0.045*24 = 1.68 USD electricity fee.
2) 40/30 = 1.33 USD hosting fee.
Total is 3.01 which is greater than currently at Hashnest.
