It has nothing to do with NFTs. And most memecoins don't really provide any profits. The only reason why they are trending is because they have nothing else besides trending. Just as regular memes. But they at least have actual humor in them, not just desire to get money.
I think very few people think it's humorous, or a joke, the average person invests in meme coin because he is addicted to big profits like 2021, actually it's okay to try buying it so you don't get curious, but use the least money you can you lose it if it doesn't match your expectations, and if you think about it, it's better to gamble on a gambling site than to gamble on meme coins.
