Recently, a Bitcoin Exchange called ICBIT quietly introduced a futures market, obviously using Bitcoins as its main currency. Gold futures trade roughly at 137 BTC/tr.oz and Sweet Crude Oil at 7.3 BTC/bbl. This may play a positive role in the Bitcoin economy which needs more ways to actually use coins instead of mining them." While this sounds intriguing, I'd like to hear a good case for why BitCoin makes sense in this context.
