Apparently his definition of solvency isn't the same as mine. The fiat price now is immaterial to the value their customers were robbed of back then. If gox lost ~850000 BTC, they aren't solvent until they find ~850000 BTC. And we all know that's never going to happen unless someone looks under Karpeles' mattress.
You're right, but refunding lost Bitcoin as the fiat cost at the time is realistically as far as it's going to get. I would basically just look at it as putting money into investments with high ROI in order to make the fiat money back, regardless of whether those investments are Bitcoin. It would be near good enough for a lot of people anyway.
I suppose it'll have to do. But if Karpeles thinks that a price rise, some money being returned to those affected by liquidators and other such circumstances entirely outside of his doing are enough for him to regain any respectability in the community, he can think again. I very much doubt his motives are aligned with those who want to recover their money, when he just wants to recover his reputation, which rightly lies in tatters.
