ROI on these?
at .75 Btc at avg 20% increase and 10 cent KWh
do these ever make the btc back?
.015 BTC per day should ROI in under a 100 days. I already had the PSU's from S1's so no additional costs there. 0.75 BTC is the hairy edge IMO.
I get no roi with 20% 15 cents a kwatt 478 gh 366 watts coins at 625 start in 10 days.
but I get roi with 14% 15 cents a kwatt 478 gh 366 watts coins at 625 start in 10 days.
since i have 4 cents a kwatt but only 800 watts available this should work for me. for the 2 on order.
I will be selling off the 3 s-1s have at my low power cost location and putting these in
