@lritter how can I mint an NFT of this poast? 

@lritter you could actually pledge to "buy" it through the fediverse non-blockchain public distributed history system, and @ada should acknowledge the "selling" of the toot ... but I think there is no way to"really" transfer you the origin and existence rights of the toot and the original author has still the right to delete it (or otherwise ;p ) ... as it's usually the case with NFT no? (a screenshot is a mere bad copy ;p )
