Let’s start with the basics: NFTs are any type of crypto asset that has a unique value, that is, it cannot be exchanged for another equal asset. Hence, its name: it is a non-fungible token. Any currency can be exchanged for another one at a corresponding value. But NFTs can only be exchanged for currencies that also match their value. Think about it this way: we know that a NFT can be sold for cash, and it can be bought with that same given value. However, if this same NFT could simply be exchanged for another NFT, then neither of the two involved in the trade could be considered NFTs.
