If MtGox only had enough funds to cover 15% of deposits, and they paid back each creditor 15% of their claim a year ago, the creditor could have bought Bitcoin with what was refunded and be in the same situation now. Instead, they seem to be dragging it out. I think most creditors would rather have something last year than nothing right now. Additionally, there's no upside for creditors if Bitcoin becomes $5,000.
