If the company goes bankrupt, its assets (including any remaining BTC, by logic) will be sold, and the money thus collected will be used to pay debts and the fees of bankruptcy lawyers and executors.

If there is any money left after that, presumably it would be distributed to the shareholders.  Is that correct?

In that case, the buy/sell price posted by a trader shoud reflect his expectation about the amount of money that may be distributed to investors.  Insiders obviously have an advantage there.

The CEO of a failing bitcoin enterprise may be tempted to take any remaining bitcoins for himself, since they are "virtual" and their accounting is more easily faked. Hopefully the bankruptcy executors/courts will be smart enough to prevent that.

(The "standard script" for failing bitcoin enterprises calls for a "hacker" supposedly stealing a good part of the bitcoins.  But that act has already been played out in this case, yes?)
