Binance had acquired Coinmarketcap with marketing/advertising in mind.There's no other reason for acquiring a service like CMC.Now they are going to use Coinmarketcap as a promotion channel of their BNB token.
We can say "goodbye" to "Binancemarketcap",because no cryptocurrency user or trader that has a brain won't trust their fake rankings.
Definitely, Binance would not do such a foolish move for not acquiring the Coinmarketcap because it is the most famous one, I saw a survey, online survey on crypto data providers labeling Coinmarketcap as the most referenced website for crypto data tracking, and binance as the biggest exchange at the moment will take over this huge thing at their side to get bigger. And yes, who will based on the exchanges rankings? If you are wary of where you are moving then this might not be the case.
By the way,Binancemarketcap is a pretty accurate name for re-branding CMC.
Huobi might follow Binance's example and try to acquire some of the Coinmaretcap competitors.
I also think maybe the Coinmarketcap has a different categories on ranking the exchanges which Huobi is not that higher from binance or in other upper rank exchanges from coinmarketcap. But if it happens that this true and Binance is distorting the rankings, then this is a big slap on their face.
