Does anybody know which BTC-rate the trustee will use IF there will be a payout from BTC to BTC? The locked rate from the beginning of the bankruptcy, or the rate at the time of the payout?

Current conversion BTC rate is more than doubled if you compare it to the locked rate which was used for the claims. If you convert the BTC bankruptcy balance to JPY, the trustee has now much more JPY to devide among everybody, so a higher % payout in JPY. But in BTC's it's much lower (approx. 45% at current rate). So if the trustee will use the rate at the time of payout everybody will get 45% of the accepted BTC balance. And if the total value in JPY is not enough, everybody will get a xx% of that 45%. Is this correct or am i missing something?

If you have GOXBTC on BB you can sell them for 0.14 BTC per GOXBTC (14%). The trustee will probably payout somewhere around 20% right (=old estimation)? But what if BTC is at current rate, or maybe even at or above the ATH when the trustee starts with the payout procedure?
