It seems like its buying a piece of media, its like digital art ownership or something. Its weird, bit coin is weird, all these digital things are weird and its stupid that any of them make money.
Bitcoin at least makes some sense it's just a currency like many others ascribed worth by people and I know the argument that originally when money was metal coins the metal had value etc etc but as an example in the UK our notes aren't money, seriously anyone in the UK go check your notes in your wallet you'll find something about "I promise to give the bearer of this goods to the value listed on this note." The notes themselves are essentially IOUs.
Bitcoin is just people with gold bars stashed away but without having to actually stash gold bars away.
Hell bitcoin is more useful in every day life than gold because some places accept it as payment while I doubt many places accept gold bars as a payment method.
NFTs though, yeh I don't get it they're like stamping "Limited edition 1 of 250" onto a regular copy of a film or something and selling it alongside the other regular copies. As is NFTs have no benefit to them over the none NFT version
