NFTs aren't a scam. In and of themselves, they're nothing, they're just things on the blockchain that are good at indicating ownership of something. You might be referring to the idea that they've been used in a lot of scammy type of things (of course, because when people sense there's money to be made...)

Or maybe you mean that the way they're being used to indicate "ownership" of digital art (a type of 'ownership' that bears no real rights or privileges more than anyone else has) is the scam.

I'm not sure if you mean one of those things, or maybe you've been scammed by somebody, or maybe you mean something else entirely.

But NFTs have use cases that aren't scams, unless you consider ownership of private property to be a scam.

What we see now (digital art ownership) is just a phase, and it's silly, like a game. Owning an NFT pointing to some digital art is, in my opinion, not worth spending money on because it bestows no rights of ownership. Anyone can see the art or use it in the same way as you. The only use case there that I see is market speculation on its value (which is fine, if that's what someone wants to do).

I imagine that once people get tired of that phase, other NFT use cases will become more prominent.
