I don't think it's a good move, why buy something when you can set up your own, there are scripts similar to Coinmarketcap and they can beat Coinmarketcap with their own games because they have a community that will follow anything they recommend, in fact, they can do better than all Coinmarketcap competitors, they are living in a word,
if you can beat it buy it.
Have asked my over again, why would an exchange have interest in coinmarketcap if there nothing mischievous involved. At a time CMC was checking on exchanges now it will be in the hands their subject. This is heading no where and will loss the value after sale drastically
