You seem too trusting.
It would largely depend upon how many Bitcoins they own, wouldn't it?
Wouldn't you like to go back in time and find out more about MtGox's security? For a group of people that value transparency and openness, you all seem to be missing the very large elephant in the room. You have no idea what the hands of the exchange owners are doing. I don't really appreciate being insulted because I dare bring up the idea that a bunch of strangers I've never met might not have my interests in mind. Continue to think like this and MtGox won't be the last large scale failure of this system. Yeah, I know a "bank" was robbed, and that's not reason enough to stop using "money". But if I have nowhere to reliably store it or exchange it, then this will remain the world's largest techie circl3j3rk.
