Some people trade and sell physical art pieces as non-fungible tokens (NFTs). NFTs are digital assets that are stored on a blockchain and can be used to represent ownership of a unique item or work of art.
Trading and selling physical art pieces as NFTs can be a way for artists and collectors to authenticate and verify the ownership and provenance of a physical artwork. It can also allow for the creation of digital copies of physical art pieces, which can be sold or traded independently of the physical artwork itself. However, it's important to note that not all physical art pieces are suitable for trading or selling as NFTs. The suitability of a physical artwork for conversion to an NFT may depend on a number of factors, such as the artwork's condition, rarity, and market demand.
Some artists and collectors choose to sell both physical and digital versions of their artworks, while others may only sell one or the other. Ultimately, the decision of whether to sell physical art pieces as NFTs will depend on the individual artist's goals and priorities.
