NFTs are now very popular these days maybe because of the unique use of it. In Crypto Game like Axie Infinity, Cryptokitties and CryptoFighters you can earn by playing the game but first you must buy your character or pet to use it in the game it depends to you whether if you want to improved your account or not. There are also NFTs like WarziX which is the platform that features exclusive artworks from the artist where you can bid it to buy or sell if you want to. And I think they are lots of different kinds of NFTs that will be made in the future because of its good progress.
