NFT's mainly work on the Ethereum blockchain and there are several marketplaces where users can create, sell, and buy NFT's. Marketplaces like Opensea.io and Rarible.com give users the ability to create NFT's by using gif files, mp3 files, and video format files that can be sold as one of a kind or multiple of a kind.

Some NFT marketplaces are already creating millions of dollars’ worth of digital art sales monthly.

Though NFT's are digital art that can be copied numerous times, when turned into an NFT, they become one of a kind that can be collected and sold as they go up in value in the future.

They are designed to give you ownership of something that cannot be copied. When creating an NFT, it is similar to creating a brand-new cryptocurrency. It creates a custom token on the blockchain network that can't be reproduced and can be bought and sold on the particular NFT marketplace.
