So how much will we receive?
20% of the bitcoin lost?
Maybe less considering that the price of bitcoins has increased? (so the ones who had money will get more)
If your claim is accepted, then you now know the amount in JPY you will be handed. For bitcoin there was a fixed price for it when this is officially announced (and the pdf was out); IIRC roughly 50500 JPY per bitcoin. So if we want to make the assumption that our claims will be delivered according to this, you will have to divide that amount with bitcoin's current value to come up with the bitcoins you will end up with.
In the last bankruptcy meeting, the trustee indicated that he might distribute Bitcoin as Bitcoin. Japan recently passed a law that recognized Bitcoin as a currency, so I think it is more likely.
Also, they are still investigating whether or not Bitcoin is missing, how much is missing, and the whereabouts of any such missing Bitcoin. There are lots of rumors that only 20% will be found, but I have faith that with all those international safety and security agencies involved that we should see near 100% recovery. They've had lots of time to sort everything out.
100% back? lol There is no incentive whatsoever for the authorities to recover the funds. The Silk Road case has shown us that even when they do their own agents are often as light-fingered as common thieves/scammers. 20~25% return tops methinks
