I had an acquaintance who spent a week or so learning about ethereum and NFTs, threw together a quick NFT site, generated some images and make nearly 500k in a weekend selling these to suckers. I think he did believe in it, but that's independent of the fact that acting quick on this made him a good chunk of cash with very little effort. Is that sustainable? of course not. It's also not my particular cup of tea as far as making money goes, but I would hardly say he's "not smart" for getting involved when he did and turning a quick buck.
