If mt gox finally alows people to withdraw and mt gox bitcoin is at say 300 usd while other exchanges are at 650 how does that work exactly?
Then people withdraw to other exchanges and get back to normal (and hopefully in that process, mtgox goes away forever).
nope. it will jump to 750$ at bitstamp and co, and to 850$ on gox. within seconds. thats what is going to happen. same situation as before that mess!
pretty simple...
