How exactly do you expect someone to know which meme coin is good and which is bad? Meme coins are all the same when they are created, they don't have projects, they don't serve any purpose, they don't provide any utility to their investors, and they don't have an organic growth mechanism which every cryptocurrency has which is why they are always dependent on community hype to gain value.
Those who have managed to become rich from their investments in meme coins, however, this doesn't have to happen to everyone because it's just like gambling where you make a bet and pray that you win it so that you get some money on top of your bet if you lose it, your money is gone.
