Did Phinn ever get his 1000 BTC returned?
Ask him. I do not know about any valid claim of such amount. It sounds insane to store so much on an instawallet.
If there was ever a valid claim from this person, it would have been paid back.
I'll take that as a 'no'.
Ordinarily I would have trouble believing that a principle in a business would be so out-of-touch that he would not know the status of a nearly $1M claim. In Boussac's case, maybe.
