I don't think there's any coin tracking website that js entirely dedicated to shitcoins. As a matter of fact, many shitcoins don't even make it to CG or CMC. Most meme tokens and some DeFi tokens are nothing but shitcoins. You may track listed shitcoins on Poocoin or you use CMC alternatives like Coinlib, Coin rate, coincheckup, etc.
Sort of but if we remove the dedicated shitcoins listing only, there are too many of them and you've just mentioned many of them. They're not entirely dedicated to it but they have the lists for it.
Just like what were posted, they create a certain section and classification for those type of projects so that a visitor would have to looked it easily through that tab.
Although OP looks for certain only for it, poocoin would be the most ideal of it if OP really bothers to see only shitcoins.
