The three meme coins you mentioned received massive support from investors and major influencers; on top of these currencies is Dogecoin, backed by Elon Musk. These currencies must certainly receive sufficient fame that makes them differ from other meme coins that did not receive strong support, promotion, or attraction from investors. As for predicting the future of meme coins, this is vague, and no one can predict it. Still, there are indicators that we can make speculative indicators on the bright future of meme coins, such as using one of these meme coins as a method of payment for significant companies or adding use cases for the currency that are implemented by developers, listing them on well-known and famous CEX platforms, the total supply of the currency is not exaggerated, and so on. For me, I see that meme coins are invested by people in order to get rich quickly. Still, they do not know that their high risks can make them turn into rapid poverty due to the manipulation from the whales and market makers and the influence of the hype on them, etc.
