A great update for the coinmarketcap, I think the chat thing would help many crypto enthusiast specially for the beginners that aren't knowledgeable about coinmarketcap exchange and good thing to ask faq's about the exchange that may help any concerns.
For beginners and bought a token that has a community that can be seen there. Questions and problems can easily be answered and solved if there's a representative from the team or devs active on that chat channel that they have.
The beginners are the ones that can benefit from this. But for some that aren't appreciating the feature because there's already telegram, it's okay too because we all know that such communities were already been built before.
