I would take that bet, except that I am insufficiently sure in my understandings of the rest of reality if I happen to win to be confident that I'd want 100 bitcoins in that eventuality.

ETA: I should note that I didn't run the numbers, 0.00000001 bit-coins is something I'd be willing to risk on a 1:2^220 chance for the amusement involved. It should not be taken to reflect a general policy of accepting wagers at what my estimate of these odds would be if I did decide to work them out more rigorously...
