I want to do my own cost / ROI analysis. However I am confused when it comes to the $0.14 / TH/s daily fee. Since I'm basing my costs on the kwh electric rate, I'd like to do the same for the daily fee. But how to convert TH into kWh?
Here is my math, please tell me if this looks right or wrong:
Assuming a standard Antminer S9 at 1500 watts and 14 TH/s
1500 watts = 1.5 kw
1.5 kw * 24 hours = 36 kwh/day
36 kwh / 14 TH = 2.5714 kwh/TH
$0.14 daily fee / 2.5714 kwh = $0.054 per kwh.
Is my math correct? If so then Bitcoin.com has great pricing at 5.4 cents per kwh daily fee!
