Nope, I will pay in bitcoins. I fully intend to pay in bitcoins (which I have set aside), regardless of the value, but reserve the right to pay in cash in case something happens to mine AND they become ridiculously expensive. I would pay $500/coin to buy them back in the case you describe. I would not pay $10,000/coin, however, if my 10 were stolen. Just protecting myself and my family from a crazy event.
