I still can't decide who's the smart guy in this bet: Jim or I.
You could say it's Jim: if he wins, Bitcoin will probably be mainstream, so worth a lot, so his win of 1 BTC will be large. If he loses, Bitcoin will probably have faded or not succeeded very much, so his 1 BTC loss will not be worth a lot. So he can gain a lot, and loose little -- almost a win-win for him.
Or one could reason this way. If I loose, so a bitcoin-bling-wearing celebrity appears, Bitcoin will probably be mainstream, so do I loose 1 BTC, but my remaining coins are worth a lot, so overall I'm happy. If I win, well, that's obviously great -- what could be better than winning a bitcoin bet
So perhaps it's a Win-win--Win-win situation in any case

P.S. I wouldn't have made the bet today as now I think I'll probably loose; but no regrets -- bitcoin seems to be actually going mainstream and I'm quite happy (see above)
. I just hope to loose this as soon as possible...
