It's always been full of hype. People are getting scammed big time by purchasing so-called "digital art" with no intrinsic value. Most digital arts in the forms of NFTs are simply images that can be found on the web for free. I wouldn't waste my time and money into these kind of NFTs except for digital in-game items and collectibles.
The worst part about this whole NFT thing is that they keep defending as "you can't value art objectively, it may worth 5 bucks to you, may worth 5 million to someone else" and make a claim that the hat wearing monkey or cyberpunk robots should worth millions because of it.
If anyone seriously considers them "art" then I am sorry but you are severely mistaken and you should not be considering that as investment but you deserve to lose all of your money and I would not feel bad for you, I hope they go to 100 million each because I rather have everyone profit as much as possible but that doesn't mean that I can see it happening at all. Art is art, this is just hype.
