one thing that make them popular is they have low barrier of entry, memecoins are often priced low, making them accessible to a broader audience, including new and small-scale investors who might be looking for "the next big thing", but i read somewhere that only 15 out of 1.4 million memecoin is success. that mean to much popularity that some people take advantage of that to creating pump and dump scheme. also influencer lot of them promoting memecoins.
And because of the price it makes it very affordable so people tend to find a lot of interest because of the price and if the coin should mistakenly have a hyped price then it as finish because everyone will believe that With this kind of price coin will do very well and that is why when they get disappointed they feel crypto is not for them and is not as if people don't make money from men coin but they put to much trust. And no matter the number of investors everyone will want their share that is what business is about so their interest is also a thing of concern because they will also have their own percentage. Meme coins hardly succeeds because most of their investors are low budget investors they don't want to spend good money on the project and they want to make money so any little money made. They might just want to share it. And most of this projects can not even pay their markets so their are a lot of factors that will make memcoins not to succeed, it's better when you are investing take it as your own risk.
