I haven't bought any NFTs and will probably not do it until I see real data on large efficiency improvements of blockchains (I'm hopeful for PoS but want real data on it). But if I would buy one I would make very sure that it was hosted on IPFS and immedietly downloaded a version to selfhost and store. People rush into this way to blind I really think. But that is a problem with blockchains in general I guess.
