NFTs can be anything digital - art, virtual experience, music, virtual properties, any digital unique thing that can be bought sold or traded online with exciting features being unique, provably scarce, tradable, and usable across multiple applications. Just like physical goods, you can do whatever you want with them! You could throw them in the trash, gift them to a friend across the world, or go sell them on an open marketplace. But unlike physical goods, they're armed with all the programmability of digital goods.
