Because there are memecoin that are 90% are made to scam people. Yes these memecoin are profitable when get hyped. But not all of them are like shiba, kishu, and many dog coin out there. Some uses the project to get some funding and do a terrible scam. It's indeed one of the crypto market side that I am definitely not gonna tolerate. Avoid memecoin and starting investing with the legit and literal one.
