Exactly the right attitude. 1 BTC is a lot of money for me, but it's less of a sacrifice than fighting in a war. It would be foolish and dishonorable if I didn't do anything.
I am 100% serious. Signing a transaction wouldn't prove anything except that I have the BTC in my control. I would be willing to give the 1 BTC to a trusted public figure to hold in escrow for the winner.
Great research. I'm sure they will be exposed. I am issuing this bounty on behalf of myself alone.
