The fuck are you talking about?
This describes quite well what i think about your posts. First, you insult me because i ask for sources, then:
And of course they exclude PCB costs because we are using the capital from the IPO for PCBs.
You confirm the reason why i was asking for a source. That the $2.2 number tells only part of the story, the actual cost per GH/s is higher.
And after you confirmed my skepticism, you cover your escape with more insults. It's not very effective..
