The explosive growth of NFTs (Non-Fungible Tokens) in 2020 - 2021 shook the mainstream and anyone from the outside looking into the Web3/Crypto world. However, the NFT standard was developed quite early on in 2018 with the implementation of the EIP-721 standard. Contrast to how 1₿ or 1Ξ (1 bitcoin or 1 ether) is fungible, which in simple term means that your 1Ξ token is the same as my 1Ξ token. It can be traded anywhere and to whomever and the value stays the same.
