I think many folks miss the point of what FutureBit and others like Nerdminer and BitAx are trying to do. I believe their goal is to produce a miner that anyone can buy and use. Right now they are not profitable and as some point out even if a huge number of people bought them and ran them they would not rival the big ops. The point is that you can't just jump to that efficiency or scale without starting somewhere.

Mining is critical and I for one support all of the efforts to make it more pleb friendly. Whether that be a Apollo, S9 space heater, or even these little Nerdminers.
