Does anyone have an offer of 17 BTC or higher?
EDIT: I contacted KNC to see how difficult it would be to transfer hosted device ownership to another person. Will update when they respond.
As estimates show it won't make more than about 13.8 BTC in it's lifetime (assuming the difficulty shifts from 30% to 38% jumps given the new hardware coming) I can offer you 8BTC to hedge my bet..
I make the above offer to point out that you are doing pretty good with the offers you already have on the table, if someone is willing to pay more than the system will make them back I think you should jump on it while the offer is still good..
