In terms of vulnerabilities, some exchanges were exploited, and some not.
But, sure OP. Just like in the real world, you need an impartial team to descend upon the situation, exit interview everyone, and determine what happened. Probably Gox has X amount of real coins, X amount of real dollars/equity, and XXXXXXX amount of liabilities.
HOWEVER, they do only have to pay 135 USD per BTC as per last bid, and therefore, the ship of Gox does 'list' somewhat upon ye fair rockes of fortune. Therefore, if windfall big investor comes in and buys their whole sack of frosting+shit, then somehow separates the two and makes it nice for Goxxies, then, I am for it. But whom has the cashbag to come in and 'rescue' Goxxies, when lots of folks like me saw it was a pretty options-free interface and therefor did not use it? Even though I am glad I had .2 BTC, I still would like to value it at whatever, say, as little as 20 USD, and have that much coin, at least.
In terms of BTC at 1000 USD then my .2 BTC is worth 200 bucks but in terms of usability of exchanges, Gox could have been bought and upgraded anyway, so, let's see what the real damage is and then maybe there is a value there. I guess what I am saying OP is that all people who had BTC at Gox now have 'buy-in' automatically for any ideas people have.
Like I said there're many options, but all hinges on restoring faith and trust. To get that you will need a completely different leadership and management group first. They can tell you there are all kinds of deferred payment programs that investors can voluntarily opt in. Say if they guarantee an annual 10% payback of the funds owed plus a 20% interest on the balance, or 20% payback with a 10% annual interest, or a 50% annual payback with 5% interest, or a one-time 80% payback of the total amount owed. Do you not like that? Doing so not only stabilizes the market some long-term investors may even earn more profits that they may not otherwise be able to get. Just one quick a dirty example..
