This is the worse situation when it bullish market, coins with no genuine use case, potentials and utility will make a ridiculous surge in price the next thing you'll see is hype follower investors buying the coin for some quick profit whereas the bubble will burst sooner or later.
I check CMC today either, I also saw the coin and I was amazed by some new coins that claimed the top #100 slot on CMC
Yeah, right now just any coin can surge among the ranks at coinmarketcap and recently I also see shiba inu token making waves all around the market but when I joined their telegram and tried to understand what this token actually does because their website just thinks it is a dogecoin killer, I got some horrible replies with everyone promising shiba to the moon while none having the requisite knowledge of how to answer a question and even deleted a few posts which asked questions and raised concerns.
Finally I was able to understand that it is another decentralized swap like uniswap, at least that's what it does from my understanding of it. Now we are seeing new coins like OP said ICP and there are going to be new coins almost every now and when on the top of the list at CMC because someone is manipulating the whole market it seems.
