Of course you had to pointedly ignore KnC, because as the most successful BTC ASIC company ever, their example proves your latter claim demonstrably false.
You forgot to add "/s" so people don't think you're being serious.
So which BTC ASIC company is more successful than KnC?
Bitfury, Bitmain, Avalon, Asicminer, Lketc..
Nobody wants to buy a giant chip that requires $150 worth of cooling when you could use smaller chips with ~$30 worth of cooling.
Bitfury...maybe. KnC already has like $20 million in the bank, while BitFury is borrowing $20 million in venture capital.
Let's not forget BitFury also had "problems actually building working miners" even with its tiny chip. They had to run it at half speed, remember?
The rest? Not a chance. Avalon pissed off at least as many customers as HF. Bitmain is still a baby. And AM's latest chip is a dud.
When you have to pay for electricity and rack space, the trivial increased cooling cost is overwhelmed by savings accrued by much higher density.
Regardless, leaving KnC off your list that purported to demonstrate the non-viability of big hot chips was a silly mistake to make.
