IMO, someone buys an NFT because he likes the art the seller provides and maybe have higher value when he have portfolio of this NFTs, even meme NFT are have an art for people who like memes, nothing wrong with that. Now, we can find many NFTs, as well as photographic NFTs that can be used as illustrations for publications and other commercial use. With this, it is very far from the point of view that buying NFT is just to give up money in a scam. However, they buy because they are needed based on their personal needs.
NFTs are not scam but very risky. Only what I can do it to create an NFT and look for buyer. I can not buy NFT because I know the hype can be cool on a way I will lose. If pump and dump are regarded as scam, the losses it bring can be what NFT will bring to some people. Some people have earned a lot of money from NFT, this is the one I heard about recently

But what makes the buyer think the NFTs of the Indonesia student picture will increase price, this can later be a loss for the buyer.
I am not saying NFT is a scam but it is risky and should be treated like that.
) - And, uh, don't sell your house to buy an NFT.
