It is not just because the MemeCoins has bigger profits that makes Investors investing little amounts there in Memecoins but it is because Memecoins is flexible to offer lost of funds overnight so investors chooses to invest with what is affordable to loose just like staking wisely and responsibly in the gamble.
And of course yes, the memecoins has the potentials to get investors rich but the Possibilities is like a 50/50 because it can be up rised for a short period of time but befalls in a longer period and if investors are unlucky the memecoin depending on where you investors can just vanish and your invested funds are never retrievable at all. So this Memecoins requires a steady track in the market cap so you could have views of your asset values fluctuating and decide if you would have to sell out or keep holding but is is very much risky to keep holding memecoins for too long due to the highily weak volatility.
In my opinion, it is too risky to hold meme coins for a long time, if you feel you have made a profit, you should sell them immediately. Because meme coin is only suitable for short-term investment, although some friends hold it for a long time, but I won't do it. I prefer top coin coins to hold long term, That makes more sense.
Tell this to "DOGECOIN MILLIONAIRE".

He's been holding a bag of DOGE for more than 4 years already, and when there's an opportunity for him to sell during the bull market in 2021, he didn't sell and got some criticisms because of that decision. Now fast forward to 2024, he's already tripled his investment, and we aren't even in the bull market yet. He bought DOGE at $0.04-$0.05 I think.
Anyway, the term "holding meme coin for a long time" is kind of subjective IMO because at the end of the day, it will depend on which coins you are holding. If you will buy those low market cap meme coins then the chances of you losing money in the long run would be high compared to when you are buying those meme coins that has a high market cap like DOGE, SHIB, etc. As for me, meme coins in general isn't a coin that I would hold for mid to long term. Short term maybe (like flipping), but who knows. I might do what the DOGECOIN MILLIONAIRE did.

Buying DOGE, and just hold it for more than 3 years.
