Ok, so I shared this with a writing friend of mine who asked their husband, who frequently buys crypto and stuff. This is what they had to say from their opinion: "You will not lose your rights. NFT is used by companies when they start up and want to build a way into crypto. They cannot buy your tweets with such a thing. This is blown up from just 1% of the reality."
Then they went on to explain that only I as an author can sell my tweets. Whether or not that's the truth idk but I'll play it safe for now and block all the accounts VibrantFox mentioned above.
