Well yes then personally I'd wait until we see an ASIC for all parties. You'd be able to sell you pre-order for a great deal more once a prototype is confirmed and verified!
You can't do that, your order turns invalid if you don't pay within 7 days of the pre-orders opening, which is another really shitty decision on KnCMiner's end. That said, don't give him attention, this is clear shitposting now.
No I meant for resale. Pay by credit card for maximal first-hand buyer protection. Check with your bank w.r.t. what they offer your card purchases.
