NFTs are basically collectibles that are sold or purchased or even traded on NFT marketplaces. These NFTs are based on the blockchain, which is an extremely secure and encrypted medium that not only allows the NFTs to be these exclusive as there are only 1 of 1. The cost of an NFT is directly affected by how scarce and rare it is. The rarer it is, the more the value of that particular NFT. There are several NFT earning platformsthat help you make money through various means. While some might involve you playing games, others might also require you to make a trade with your NFTs.
