Many worse things have happened in the business world. Even if you had your life savings in BTC, it wouldn't be a good reason for that.

Just hope they come out with a fair outcome for all investors, with whatever money is left. We don't know the full story, maybe the coins are recoverable. If nothing else I hope mt gox quickly makes a offer to people who lost out. I don't want to fork out for lawyers fees, although I guess it may be necessary if there's any chance of getting anything back
