I've written posts critical of cryptocurrency before. People have made a lot of money from it, but I still worry it will turn into a house of cards that comes crumbling down at some point (I could be wrong and just look like an out-of-touch old fogey, but so is life). To complicate things further there are now NFTS (Non-fungible tokens), which are basically digital pieces of art that utilize blockchain technology (like crypto uses) to make a piece of art that has unique data making it valuable because...well, just because. This article by Mitchell Clark helps explain things a little bit but don't worry if you're still bewildered, I am too. It's basically jpegs worth thousands or sometimes millions of dollars because they contain unique coding, as I understand it.
Blockchain mining is of course pretty bad for the environment and some think NFTs just sound like a big scam, but a lot of artists have found it helpful to them when it comes to making some money. Corporations, of course, are interested now too, be they a video-game studio such as Sega, make Magic cards like Hasbro, or comic companies thinking about making NFTs. The whole thing just confuses me even as I try to learn about it. I won't be, "Investing," in NFTs, but more power to those who do.
