I purchased my first ever NFT by linking my MetaMask Wallet with OpenSea. I’m going to wait until we’re all on Mars before I consider selling it. In the meantime, I’m going to be adding more to the collection.).
About NFT’s
A non-fungible token (NFT) is a special type of cryptographic token which represents something unique; non-fungible tokens are thus not mutually interchangeable.
Non-fungible tokens are used to create verifiable digital scarcity, as well as digital ownership, and the possibility of asset interoperability across multiple platforms. NFTs are used in several specific applications that require unique digital items like crypto art, digital collectibles, and online gaming. (via Wikipedia)
