I am so sick of people complaining. KNC set out to delivery the machines by the end of September 2013. Look at where we are today. If the machines hash faster than what you originally paid for, are they asking for more money??? The BTC difficulty has nothing to do with KNC so STFU about it.
Congrats KNC. Keep rock'n. Home stretch!
I'm not saying anything against KNC, I'm happy to see all pictures and video posted today and waiting for my device, only saying that it was quite bad investment as I can see now.
