I checked against MtGox leaked database what would be the balance threshold if we applied this rule: it yields 0.49 BTC. So potentially, that would mean only people having less than $300 worth at stake would get back something. In other words, only people whose life has not been affected by this debacle would potentially get back something significant. That seems unfair to me.
Here's my math. Please tell me if it is somehow wrong.
127,000 total depositors
850,000 BTC disappeared
200,000 BTC found
number in 80% group of depositors ( .8 )(127,000) = 101,600
" " 20% " " " ( .2 )(127,000) = 25,400
original funds:
belonging to 80% group ( .2 )(850,000) = 170,000 BTC
belonging to 20% group ( .8 )(850,000) = 680,000 BTC
30% contingency withheld for unclaimed and/or recovered coins (only applies to 80% group)
(.3)(170,000) = 51,000 BTC
amount returned under proposal to 80% group 170,000 - 51,000 = 119,000 BTC
average return per depositor in 80% group 119,000 / 101,600 = 1.17 BTC
amount returned under proposal to 20% group 200,000 - 119,000 = 81,000 BTC
average return per depositor in 20% group 81,000 / 25,400 = 3.18 BTC
The latter does not include any returns eventually coming back from any recovered from disappeared 650K BTC and/or any stock distributions. These would never be available to the 80% group, since they have already been paid off.
