WTF is a NFT??
In short, another way to pull money out of nothing. Like Bitcoin or the stock market.
More specifically, a way to denote that something is the original. You make a crappy 8-bit Paint drawing of a frog urinating on Earnest Borgnine, tokenize it (which is the T in NFT) using a unique hash, and then let it go viral. A year later you sell the token (the F is for Fungible) and some nitwit buys it up so he owns the original.
The part that's of interest to you is that we'll start to see songs tokenized. It can be done to anything digital. People can buy the very first incarnation of a song, or an album, or an album cover or whatever else the artist thinks to tokenize. Sure, twenty million people own a copy of it on iTunes, but one person will get to say he owns the original. Frankly, it's completely ridiculous, but, uh, yeah capitalism, I guess.
At least that's how I understand it. I'm sure some of the younger folk here will elaborate better than I can.
