OK. But that's disingenuous, because we were originally talking about the risks of exchanges.
Also it assumes you can move money through them at will, which did not happen at Mt Gox at least.
AFAIK, you can't move money through any exchange at will, at least not as "at will" is ordinarily defined. There are transaction limits and mandatory waits for withdrawals and so on; you can't just put your 1,000 BTC into an exchange and then turn around and withdraw your $450,000. The entire BTC system appears to be very thinly capitalized; for all the talk about the billions in "market cap", I doubt there's as much as $5 million in fiat in all of the exchanges combined.
