I recall that fillippone is the beneficiary of another gift from proudhon, and I cannot remember the terms, but it has to do with the BTC price reaching a certain level.  Gifts can be a tricky category, since they are unilateral rather the bilateral aspect of a bet, and surely there seems to be an ability to retract them at any time and so the recipient is not exactly entitled to receive them, even if their might have had been reliance upon the receipt of such gift.

Quoted for reference.
Please someone help me remember when it happens!
