NONE of these scam sites have managed to send prototypes to be varified by a trusdted third party.
NONE
NONE of these scam sites have had any developmental contact with the gurus of bitcoin and mining software
NONE of these scam sites have a business history in bitcoin. In fact thier posting history on this foram generally started at the time of the scam. If you've been into bit coin for years you'd think you would have shown your face some where.

I'm really hoping KNC come good, and that the 28Nm ASICs and thier integrators get announced soon. Even if these guys aren't a scam I would give them money. Hell after the incompetence of BFL and the decent public face they at least put forward........
(note I didn't say respectable)
