Creditors should get back the asset (remember, BTC is defined as an asset currency by IRS) they paid. Would it be acceptable to sell a bunch of specific gold, silver, paintings off? No. Give the assets back when the civil judgement is rendered.
And what about creditors who are owed USD?
What proportion of the amounts owed are BTC, and what are USD?
How much total BTC will be recovered? How much total USD will be recovered?
None of those figures are known.
The receivers will liquidate any non-money assets owned (yes, including gold, silver or artwork) to determine the final asset value to be shared out.
The BTC are not still yours, held on trust by BFL. You are a creditor, and they owe you a debt.
