90% of the artworks listed in various marketplaces, are not original. Get a subscription of Veectzy or placeit, you will get millions of such artwork at nearly free of cost. Add some random shapes to those, boom - you have a digital artwork ready to be sold in NFT marketplace. Since I have been designing artworks for my own t-shirt business, I can relate to these.
NFT will only live in games market where people will buy in-game accessories from the game's developers. Otherwise, the whole NFT things is a hype and nothing else!
As long as you offer people an option pay a little, game a little, earn a little trio then they will do that because what else could make you money while having so much fun. Obviously some people are doing it as a job, but that doesn't change the fact that they are still doing it, and many are doing it because it is fun as well. I have seen people get rich with NFT games and still continue just for fun instead of selling and turning that money into cash (or other crypto).
