I feel like it's an extraterrestrial thing on earth but who cares as long as cash can be made. But one thing I noticed is that these NFTs are not easy to sell, one in thousand would get sold but seems like it will change once it goes mainstream.
I saw a reply by ETH founder on Twitter to a question: "What's the most surprising thing for him" and he replied: NFTs.
I also think that NFTs are really the most surprising things of this century. Not to mention, they will create more and more chaos & hunger, sad but true in my opinion.
