In terms of exchange ranking, both CMC and CG may be unable to get the perfect data for ranking due to common practices of wash trading, bot trading, fake pumps many exchanges indulge in.
I heard that coinmarketcap was sold to Binance. Is there any truth about this news ?
Also i see a lot of ads in coinmarketcap which is another reason i use Coingecko more often these days.
I am not sure if its already bought or not by there was a news few months ago that Binance will buy coinmarketcap.com for 400 Million dollar. That's a lot of money for this domain.
The Crypto Industry’s $400M Cash and Stock Deal - Binance to Acquire Coinmarketcap.com
Binance has since acquired Coinmarketcap close to 8 months now. It's a done deal. I think since Binance took over, CMC has improved on its data analytics used for ranking exchanges. The issue of fake volume due to bot trading and wash trading can be problematic for these platforms to deal with. Everyone wants to feature among the top global exchanges.
As we can see in the list of exchanges. https://coinmarketcap.com/rankings/exchanges/
Binance is still dominating, it has a volume of $5 billion now, while the 2nd was only with less than $1 billion.
