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.
Hell, Sam should just take the bitcoins from the buyer of the pre-order queue position, putting the seller's pre-order in the new buyer's name, then give a receipt.
