Disbursing funds to some customers and not others would be a criminal act under those.
I believe a court order (injunction) should be filed to help ensure the exchange operator proceeds as prescribed by law.
Bitcoins were stolen, not cash. That cash is not Bitfloors to distribute to other customers. It's mine.
You assume that Bitfloor is under the same regulations as a brokerage requiring segregation of customer funds. I don't believe that is the case here, and even if it was, that is of little protection as we have seen recently with supposedly segregated funds in the MF Global and PFGBest collapses.
In this case I suppose it will come down to whether the Bankruptcy Judge finds that the Bitcoins stolen at the time were of value too (and must be replaced at their market value in USD) or not.
