Well, A gets 0.154 BTC which is $1.54, but he was only owed $1.00, so he's made a profit on the deal which doesn't seem right. I don't see why anyone would be entitled to get more than 100% of what they're owed, unless everyone does.
Fair point!
And I'd rather this be settled without expensive fees being taken out by lawyers. I've already consulted one who has told me for claims any less than $40k, its simply not worth it as the costs will outweigh the potential return. Official letters have to be sent to serve as notice and fees alone for these letters to start the process are around at least in the hundreds of dollars.
