That’s a nice pipedream, but why would airlines move to this system? They seem perfectly happy with the current system where you have to pay to change anything.
And the game thing doesn’t make sense. If the game shuts down, where are you going to use your NFT? There’s a few crappy crypto games that have tried making it so items are transferable, but for larger games it sounds like a nightmare to implement.
NFTs are like crypto, a solution in search of a problem. I’ll be honest, I’m anti-crypto and NFTs, but if a valid usecase presented itself I’d be happy to be wrong. I just haven’t seen it yet.
