You're missing two key figures
$8/GH vs $17/GH
but more importantly
0.6w/GH vs 2.5w/GH
That second number is absolutely key to sustainable mining.
http://mining.thegenesisblock.com/ figures says that a October delivery of a KNCMiner unit and Hashfast November unit has a better ROI than a Cointerra December unit.
KNCminer: 63.7% ROI
Hashfast: 52.% ROI
Cointerra : 37.5% ROI
tell me. If you have only a million dollars to invest, which one or two would you invest in?
I'd move out of the U.S. fuck off Bitcoins and U.S. dollars, both are heading the same direction due to a stupid group of clowns hoarding them.
