I’m no expert on NFTs but, honestly, even reading articles including the one above, I can’t get past the sense that what you are buying is simply not worth having. It’s not like buying the original of an oil painting. Or the rights to a song. There’s no real ownership benefit to having your name in a blockchain saying you own it save the hope that other people value it and will one day pay you more money for it.
