They seem to have completely different mechanics, aside from failing within a month of each other there is almost no other mechanical similarity between these situations.
A troubled company's balance sheet usually looks like:
Assets: A Mess
Liabilities: A Mess
None of the claimholders (liabilities) know what they can withdraw, when, etc. A "buying asset" bailout often happens when someone (like Goldman here) comes in to buy only the gross assets. They will pay $2 bln in cash for the assets, and divorce the two messes. The two companies afterwards are now:
NewCo:
Asset: A Mess
Liabilities: None, other than their new single equityholder, Goldman.
OldCo:
Asset: $2bln
Liabilies: A Mess.
NewCo is controlled by one person (or a tight group) and can unwind its positions slowly at leisure, waiting for prices to go up, with no more (financial) liquidations.
OldCo has a much easier time. All creditors are called to line up in order. A judge decides who is most senior. The senior most people go collect their money (chunk of $2bln first). People queue up until the money is gone. In the highly unlikely case there is any money left after all claims are paid, the money goes to the old Celcius equityholders.
