Non-fungible token. – Right, sorry. “Non-fungible” more or less means that it’s unique and can’t be replaced with something else. For example, a bitcoin is fungible– if you trade any coin/token which is fungible , with another same token, and you will have exactly the same thing.
A one-of-a-kind trading card, however, is non-fungible. If you traded it for a different card, you’d have something completely different.

How do NFTs work?
At a very high level, most NFTs are part of the Ethereum blockchain, though other blockchains have implemented their own version of NFTs. Ethereum is a cryptocurrency, like bitcoin or dogecoin, but its blockchain also keeps track of who’s holding and trading NFTs.
What’s worth picking up at the NFT supermarket?
NFTs can really be anything digital (such as drawings, music, your brain downloaded and turned into an AI), but a lot of the current excitement is around using the tech to sell digital art.
