Not sure if what knowledge can do in meme coins since all of them are the same. But maybe it helps us to be aware if what meme coins are going to get pumped and if how long we are going to HODL them. It gives us a gut as well to take a risk on them. Any cryptos can fall anytime without prior notice. It's just that meme coins can hardly recover anymore.
There are also whales in non-meme coins but it's just that meme coins are more easier to manipulate. But, a lot of us who invest in non-meme coins can still suffer due to the whales. Their main intention is to profit and not to play but sometimes they need to disrupt our thinking if they experience some difficulties or if they want to earn more.
Meme coins should be avoided, even if we were to consider the massive profits an investor could obtain by putting their money on the correct coin, the risk will still not be worth it.
Since there is not really any way to predict which one of those coins will experiment such growth, and while there are many investors out there that claim to know this information, they are either lying or overestimating their capabilities, as most of the time the only differences between a successful meme coin and the hundreds of failed coins that exist is a nice name and an effective marketing campaign.
