Buy those artist creations that you think will be valuable in the future. It's like entering an auction for artworks, paints, or collections.

You now have the authority of someone else NFT if you were able to get it. There are some rare NFTs that have a great market value because some buyers really want to collect it as it was a limited edition and no plan for them to sell it later on.
