If any CME members or maybe CME Chairman himself are reading this forum, or if someone has access to higher ups in CME, maybe its a good idea to use your contacts to suggest them to introduce BitCoin futures. Who cares if the digital currency survives or not or if it changes its form etc. but I am sure futures on BitCoin will become a hit overnight. Might be a great new product for CME. Presently, people have to open a new account with Mt Gox if they want to trade spot Bitcoins. Bitcoins futures listing on CME will allow a much larger trading community access to this contract Personally I think idea of Bitcoins is in early stages of its development and government can effectively control it to some extent if they want. Especially after couple months ago raids by federal agencies. Still, as a short term intra-day speculation vehicle, from a futures trader perspective, it ought to be just GREAT - with 5-20% swings......WOW!!!! The reference spot market should be Mt Gox. This is just my opinion and ofcourse CME guys can decide to choose the one they want.
