This is not a surprise because it is expected. They will create a coin, people will buy and pump it and later dump it and move to other coins. Meme coins are not different from altcoins. If you want to gamble, gambie with them. If you do not lose money but lucky to gain from the one that you bought, sell it as fast as possible.

So the future of the coins is that people will buy them and later dump them and move to new coins. The new coins will become old and they will also dump it and move to a new one and so on.
