Bitcoin value didn't sink. The exchange rate on MtGox took a dip from $930 to $760 between yesterday and now but on other exchanges like Bitstamp it may have gone from $790 to $750. The rate on MtGox was higher than on other exchanges because it was hard to get cash out of MtGox. Hence if you had money on it, the easy way to get it out was to buy bitcoins, transfer them to another wallet and sell them on a more liquid exchange like Bitstamp or btc-e where USD withdrawals are quick. This created too much buy pressure on MtGox and this pressure faded when they made it hard to even withdraw bitcoins. That explains the crash on MtGox but its amplitude was nowhere as large as on other exchanges who by the way handle larger transaction volumes now.
