No platform is perfect, under Binance management, maybe they can improve it, but the fact that they are visited by millions of people, that says a lot of people trust their information.
People are familiar with Coinmarketcap's interface and is the one that started this market cap graph, they have established loyal supporters I am one of them, but there are also some sites that offer better features but I'm not leaving Coinmarketcap, I prefer to include the others for comparison, we actually need at least three for better comparison on the price.
