By the way, I also noticed this trend that nft is now a very big part of the cryptocurrency world where people make money from, but I can't understand what exactly they make money from, whether they just create pictures and sell them on the market, I don't know. Of course, I found the resource https://blockchaindose.com/ which has a lot of information about nft. But I haven't delved into that topic yet. So I think maybe it will be useful to you and you will find the information you need.
