How do you know there wasn't a failed 40,28 and 20nm design? Do you have better insider knowledge than the CEO of SPtech who is in bed with Bitfury?
You're asking me to prove a negative now? Show me where Bitfury announced a 40 or 20nm design, specs and timetable and then blew it.
Out of passing curiosity, feel free to point out where the CEO of a competitor made that claim, but I dont even see how thats relevant.
Their first chip is a perfect example of how they will overclock it until they need to underclock.
I'm willing to bet they still haven't underclocked their gen1 hardware because it doesn't make sense financially with their ultra cheap electricity rates.
FFS, a few months ago you never even heard of Ohms Law or a shmoo plot. You're gonna argue this with me now ?
What a clown you are. BTW, how's your petamine investment doing?
