Too bad for all the suckers who paid in bitcoins though, eh? Especially since you can't get a bitcoin refund.
KNC does bank transfer refunds

At current value. Not your original amount of bitcoins.
They don't hold any bitcoins or at least I don't think so.
All they got are fiat. Bitpay > Fiat > KNC
What the hell is a bank transfer refund? How long do they take? How much do they cost? Then you have to get that money back into an exchange, pay the exchange fee again.
