NFT (Non-Fungible Token) is a contract that is stored on a blockchain and represents its holder's ownership of a digital or physical asset, for instance, a piece of art or a ticket.
An NFT is initially created (minted) on a blockchain and holds unique data that can't be overwritten. Thus, anyone can trace the ownership of a particular asset. Any unauthorized copies are easily exposed.
Gaming NFTs can provide access to game apps and tournaments, or be directly used in gaming scenarios. By owning gaming NFTs, users literally own a part of a game.
Since owning a particular NFT is often the only way to start playing a particular game, NFTs for trending games can quickly rise in price.
Meanwhile, to profit from gaming NFTs, one doesn't need to be a gamer: you can explore collectibles, and check tendencies and stats.
