A NFT (which is short for non-fungible token) is similar to regular tokens such as crypto currency and utility tokens, but is something that can be compared to a collectors item rather than just another token.
An example might be that you have pokemon cards, and there is only one of each, or a few of each. And if you own one of them you own that copy of it. When it comes to crypto cyrrency such as bitcoin one bitcoin is not really different from another bitcoin, they have the same value and uniqueness. NFTs are still relatively new and it has a lot of potential uses, we have to stick around to see what can be dreamt up and created!
