NFTs can be pretty valuable in a couple of ways. Apart from being investment instruments with high-profit potential, they’re also used to establish identity, community, and ownership. Some people buy NFTs to support artists, and the artists often earn more from this since they profit directly from their works without intermediaries.
As a new form of collectible, NFTs are digital upgrades to items like arts, comic books, posters, sports cards, etc., attracting many to buy NFTs not because of any monetary gain they expect but because of the other values they have. Sometimes the value could be in the form of exclusive access to events, for gaming purposes, or some just buy it for the novelty of it.
