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.
When it comes to creating and developing stuffs, there's no point of reinventing the wheels. I'm thinking the team behind binance thought it through before deciding that spending as much as $400M – (Creating a web platform like Coinmarketcap should cost 4 times less). Moreover, most times, they more better options in crushing competitors is to acquire startups/firm rather than creating new range of products. Remember how Google and Microsoft acquired so many projects already? That's it.
