Very good question. Is there any proof that they really have 16nm-chips? Their share of the hashrate is/was small...
I posted about this in the main kfc thread, their investors claim big technical problems
https://bitcointalk.org/index.php?topic=170332.msg14997169#msg14997169Either it was a massive bluff about 16nm or they have 16nm, but they are massively failing/underperforming. Either way, fuck 'em. They deserve some karmic payback

More info on this, translated from Swedish:
http://digital.di.se/artikel/knc-agaren-vi-hade-inte-koll-pa-produktenYou are satisfied with the disclosure of KNC?
"We get reports shareholders. KNC build the new circuit board. When they failed to get the right processors, they can not produce the coins fast enough. Then you are not competitive. It's a hardware play this. Like when Saab cars based on an old platform. "
So I guess kfc fucked it up technically, as well as all the other bad decisions they made.
