Please correct me, if I'm wrong.
Let's assume they
1) produce a 28nm miner for $0.06/GH
2) operate it at 0.36 J/GH (conservativ guess)
3) while having electricity costs of $0.05/kWh (or less)
they should make $0.03/GH per month at the current difficulty, which means ROI in about 2 months.
There will be probably first miners based on Bitfury's 16nm ASIC in wild and their DC end of March, but I guess the real volume ramp up will happen in April.
So it should be enough time, to make some profit with the new 28nm hardware.
I don't see how it would be possible to produce full working miners meaning PCB+chips+components at $0.06/GH. Even if this were true, which I find very unlikely, the big private buyers are being ripped off big time while we are being lied that BitFury is trying to help the decentralization.
