Meme projects if you will try to look at the reasoning of their existence, will give you idea whether they can survive long or not. Because most of them have shallow foundation, you can expect that they won't last after the team exhausted their opportunity to pocket money as much as they can. Hence, a very risky move if you will invest your hard-earned money from these projects. But if you have the time to keep up and explore their profitability, why not? Most of them are just for short-term profits. If you fail to keep up, you will be holding worthless tokens later on.
That is exactly what people should be looking at, we are talking about something that is not there for you to make money, and because of that, you should not invest to make money neither. If the premise of a project is "look how fun it is, why don't you fund us?" then it's clear that they are just trying to make money and nothing more, that's it. This is why it's smart to avoid those projects, and invest into something a bit more serious.
I understand that it is going to take a while, but it won't be really that complicated neither, it is something that will not be easy at all. We should realize that it is going to be a little harder, because picking something for fun is easy, you just pick the most fun name or something.
