In my opinion the trustee isn't going to buy or sell any Bitcoins, because of the Japanese law and all the work which comes with it. Buying a not recognized currency is ruled out I guess (unlawfull/working with the devil). Selling, maybe, but if he can solve it the easy way...

The easiest way to avoid buying/selling is to payout everybody in both JPY and BTC, no exceptions. A percentage of the overall percentage. But payout everybody in JPY is alot of work...
Or maybe a percentage in BTC and the remainder in JPY only if the trustee doesn't have enough BTC (avoid buying).

If he can payout everyone who choose for payout in BTC, then he will have a remainder which he has to sell.
If he can't payout everyone who choose for payout in BTC, it won't be fair to payout some people in BTC and others in JPY.

At this point the trustee can't make a choice, even if he wants to...


And what about the GOXBTC at Bitcoin Builder? The owner of that site would not be very happy either if the trustee chooses to payout both JPY and BTC.
Does anybody actually know if Bitcoin Builder filled a (BTC) claim already?


I was just thinking of something else: Is it theoretically possible to get more then 100% back?
(Bitcoin price at $800 (or even higher) and not all Bitcoins claimed due to different kind of reasons).
