in the event of bankruptcy of an financial institution
ALL CUSTOMER'S DEPOSITS BELONG TO CREDITORS
Yes, that is true.
When a firm is bankrupt, they cannot legally give preference to some creditors over others. That's for a court to decide.
But we've seen at least one significant potential case of such illegal preferential payments, in the case of Otoh the DASH whale.
Otoh may have
used his high profile to threaten adverse publicity for Cryptsy in order to be allowed to jump the queue, and get his coins out while lesser non-VIP types were stuck waiting.
That could mean he's going to have to deal with clawback, and (especially if he resists) legal discovery.
If this gets pulled into BigFraud's divorce proceedings, there won't be enough popcorn in the entire universe...
The former Mrs. BigFraud won't want to deal with her ex's and/or Otoh's hundreds of Masternodes, which is why standard procedure is to liquidate (IE market dump) assets and divide the fiat proceeds.
