The main factor you have to consider is risk because the risk of investing in meme coins is very high. I can't recommend you to invest in certain meme coins that might be hyped in the future and will give you huge profits, but I suggest you to choose some meme coins at random and invest a little of your money.
You can't know what memecoins might be hyped in the future, it's a combination of luck and a PR campaign. I think if someone wants to invest in memecoins it's a good idea just to throw a few bucks in some memecoins, one of them might pump hard, and you might sell it before it's too late.
