Meme coins very risky. Maximum meme coin is scam. They make a profit in a very short time and make a profit in a very short time. If you want to take profit from these, you have to go out again with the entry at the right time. It is best to stay away from these.
I agree with you that the majority of meme coins are scams. I investigated smart contracts some of them (especially those that contain in their name "dog" like lady doge, baby doge etc) and almost everywhere I saw functions that showed me that developers just wanted to ride the gravy train. They just used the fact that dogecoin was trendy and people believed that meme coins were really profitable so started creating plenty of such coins.
