Thought experiment.
So your biggest crooked customer has a balance of 10% of your net liabilities. And someone steals 1/3 your net worth so you're basically outta business and the biggest crook on the planet just took a 1/3 haircut, which he's not going to be too happy about.
You tell the biggest baddest gangster of a customer, you can more than triple his current balance at the mere cost of guaranteeing your personal safety in perpetuity and having a crony of his and a crony of yours re-enact the 1/3 theft. After all, you just figured out what happened, and its not going to be too hard to arrange for it again two more times.
So that leaves the biggest crook in the world in debt to you, a fat bank account, and lifetime guarantee of protection from said crook.
Do some deals with the crooks competitors to make sure they know he gave you his word, so if he ever goes back on it they'll never trust him again. Or run the same scheme three times and make sure the top three crooks know that the enemies of the guy who kills you off are going to split your fortune if you croak.
Or lets say you make "all" the BTC disappear but you actually have enough control to reimburse every player big enough and criminal enough to actually hurt you, with millions left over for yourself.
Your biggest customer is about to get powned as a money launderer by the DEA/IRS and his only legal hope is to make your records look untrustworthy. Would any court of law trust MtGox's records after today? I guess there's no proof anymore that some bad guy was about to get powned. Well, there's an easy way and a hard way to do that, at least WRT collateral damage to the execs family members. And if you still tangentially somehow have control of the "lost" money, nobody important need actually hold a grudge.
I'm not saying any of this is true or even possible, although it could be the plot of GTA:7 or similar. These are better hollywood movie plots than the formulaic dreck we're forced to endure.
