You have relatively answered the questions that arise in my mind. It would be nice what you said, yes. For example, a contest is held and those who participate in this contest will be able to sell their works with NFT. Of course, not just that. Anyway, if blockchain is a register, the artwork will remain on this basis. We can consider moving Steem Tokens to other NFT markets, this could also be an NFT network that the Steemit Team will create. Thanks sir @dobartim :)
