It's too much for a crap exchange site like coinmarketcap which always helping scammer. I personally will prefer to see binance will try to acquire crypto rank rather than MCAP. it looks like that binance is looking for the traffic that has already acquired by MCAP site.
Not for advertising, now most of the people are searching coins through CMC, which many people are losing their money through fake pumps which are listed in the CMC. Once if Binance acquires CMC there is a huge change in terms of listing because the will be in a selective manner in order to eliminate fraudulent.
People will still says it is centralized that not all coin is getting listed on the CMC. Gone are the days that CMC too have strict rules regarding listing. In fact getting listed on CMC before is a positive signal that can influence the trading volume of such coin on any exchange it is listed. The fact still remain that many people want a platform that offer strict rules regarding fake and shitcoin but a lot of people will still complain of centralization
