The network hash rate is 43 PH/s, up from 1 PH/s in October, and 21 PH/s 60 days ago. Shortly better mean something, or even 5x the hardware will be mining < 10 % of what it would have been in October.
At this point in time, I don't see any use anymore for the Upgrade kits and the Batch #2 machines.
Even the MPP on the Batch #1 BBJets is going to be a waste of electricity, if it ever ships.
Thanks
a lot for NOTHING, Hashfast
...fixed it for ya.
