Isn't it better to buy s7 ghs from hashnest since it's alot cheaper than purchasing the physical miner? And it will also be shipped to you eventually when they shut them down :-p
A lot cheaper how? 0.24cents/GH is not really any cheaper, its actually fairly more expensive and you pay a very high fee for the "hosting". The S7 goes for like .2 now, albeit before shipping + duty etc, and without a PSU.
