You mean you have been noticing how a lot of people have been scammed and lost their money to memecoins, lol. I don't know the revival or boost you are talking about, the only boost is in the number of people launching memecoins, even Donald Trump got in on the act, but as for value, hard to see any memecoin that has that, just hype and later end up as a scam.
More and more of them keep on coming, but they all share the same idea - drain, and rug, and keep doing it until all is in fire.
