There are tens of thousands of coins and tokens. People who buy meme coins sometimes use them for speculation in the hope that with a little capital they hope to increase by thousands of percent and get big profits. Even though investing in meme coins is very risky because we cannot measure the fundamentals and we also don't know who is behind the coin and what they are doing and for what purpose.
Memecoins is entirely gambling and a thing of luck because there are too many of them and the failure rate is so high. I think anyone buying memecoin should follow it like gambling where you know that the chances of losing all funds exists. One can get lucky to hit the jackpot with altcoins and the reward for such is just like winning a jackpot in gambling. I'm still thinking of buying altcoins but chosing the right one is the problem.
