Appear suddenly, disappear suddenly.. memecoin hype is like that... something that appears in a big way, usually has a community base that is not loyal enough to the development.. their focus is only profit, so it is natural that many new memecoins try to get the hype and then go home with 100x profit and after that abandoned...
actually it's not only $hamster or $cats that experience something like that, there are still many other memecoins that are not so exposed that also suddenly disappear...
if you look at the top memecoins today, such as DOGE, SHIBA and PEPE, they have a loyal community base... and we see recently is PENGU, yes after the airdrop that was very profitable for many people, PENGU is now a top memecoin too... but no one knows, whether this will last long or not... let's see in the future.
