Ethereum was the first blockchain to support NFTs. Many other blockchains have added or plan to add support for NFTs. Crypto.com, Open Sea etc.. You can create NFTs using those blockchains as well. Ethereum is worth more so generally those NFTs are worth more. I might pay $20 for an NFT just to say I have one and see how it works with my phone app, other than that.... hard pass.
The NFTs for the most part are made by the artist and a program changes each portrait NFT to something different while leaving the base design of the portrait. That alone makes it even dumber. You will hear the word "Minting". You can mint just about anything into an NFT if you want. Considering an NFT is just data that is stored on a digital ledger, you can store any data you want.
