I would recommend you to stay away from that NFT thing, no body will invest his/her money on a digital art these days. Most of the NFTs are just a piece of art, and millions of such art pieces are available on stock photography sites. In 2021 NFT hype was created just to take advantage of those inexperienced wealthy people who would put their money on such things because they are living in the dream world.

Even if you create that NFT collection for Elon Musk, he will never put a penny on such collection. Truth is bitter but we must have to swallow it either willingly or unwillingly. He is a business minded person who works day and night to earn more and more money so he can work on those amazing projects that very few people can even think of. Someone like Elon Musk is not going to be interested in that collection of art, that is created only to grab his attention.
