The main question is, why are these NTF tokens so expensive?
I tried to figure out the pricing.
For this reason, it usually depends on people's interest in buying the NFT and also most expensive NFTs are limited edition NFTs, and also currently the most expensive NFT is Art NFT because the price can reach above 20 eth, For example NFT made by Ashton Kutcher, the paintings he made are ridiculous but maybe because he famous public figures when he did the auction sold over 20 eth.
The most expensive NTF token is the one that the crypto community knows about. It is enough to promote the picture on Twitter
