Yes, it's very simple and that's why you see a rampant of NFT coming already from different people who are longing to sell their digital arts for a quite good amount of money or at least, make money from it.
All this NFt craze is looking more and more like bubble going to burst. i wish that NFTs would be accepted more slowly and rationally.
It will decrease in demand and craze soon. Just as you've said, the bubble will burst and everyone who's into it will likely to be disappointed when the hype and craze becomes slow.
