When I look at the Meme tokens, I see the classical pump and dump model that is repeating on a daily basis. Some make money but a lot are losing. It's not perfect either but I really don't think that investors should trust only the goodwill of the person that created the token...
I'm certainly not an expert in them, but I read or hear about them from people I know or follow, without actually getting involved by buying any. Those who get involved "professionally" have an entire list of things to check before deciding whether they want to get involved with one or not. And usually they still put small amounts on a ton of them, on the hope that a few will moon and the rest will go to zero.
