Anyone can easily check the popularity of any meme coin by checking their market capitalisation. To an extent it shows how much investment has been made by investors. As of now Dogecoin is still the biggest followed by Shiba Inu. Investors are still investing in meme coins that came into existence after the last bull run. Only a few new meme coins have become popular but by the next bull run this list will change as some of them are gaining good popularity.
Meme coins never last forever they are just gusts of wind that come and go. No meme coin is more reliable than Doge and Shiba where people are making a lot of money daily and people have lost millions in them as well. Despite this fact, many traders like to invest in meme coins to benefit from it.
However, it is everyone's own choice, everyone has their strategy, which they follow in trading and take profit and loss in it. I don't consider meme coins to be very reliable and I don't like trading meme coins, so I don't have a good opinion about them, but those who might have benefited from them would have a different opinion, but overall, we can't ignore the fact that meme coin investments are extremely risky and one can lose all their money in them sometimes.
