NFTs are collectibles built on top of crypto, though. They're not the same thing as Bitcoin/Ethereum (which have much more utility, and crucially, are fungible).
The vast, vast majority of collectibles that have ever been made are valueless, or nearly so. Just look at e.g. all the CCGs that have ever existed, vs how many of them have retained value.
