No matter how beautiful, flashy, or weird an image or video is, I don't think it sells like NFT for a lot of money unless you're a famous person.
The hype, the fact that it is an art form that could be used for the first time. NFT is art, well art is sold in NFT form at least and that was never done before, now there is a huge hype for it and that's why it's going for this much. I can guarantee you that it will not be sold for this much amount in the future, it's going to go down for sure and many small time NFT products will worth nearly zero, it's not going to worth this much at all, but I am sure that it is going to be something decent at the top.
Some NFT will worth millions anyway, even when hype dies down, but it's going to be very few of them and almost all of them will go down in price, so even if it is at the top, instead of being 69 million dollars, it will be 5 million dollars or 10 but it will still be worth a lot. There will be some that are 5k dollars today which will worth under 100 bucks in the future. It's all a big hype and nothing more.
