I find it extremely sad that there has to be such a thing as a "confidence indicator" when it comes to giving a numerical score to guide you as to whether you can trust the numbers an exchange is giving CMC. All exchanges should have 100%, period. If you thought we were out of the Wild West days in crypto, this ought to prove that wrong. There's no way any brokerage would get away with faking their trading volume--at least not for long, and the gain you'd get from faking numbers is paltry by comparison to the damage that can be done to your exchange if and when that BS gets uncovered.
After Binance has purchased the CoinMarketCap site, it appears that she will make many updates
Binance probably won't get offended by someone misgendering them, but beware: the pronoun police are lurking everywhere. (lol)
Anyway, the changes are to be expected and hopefully whatever changes are coming in the future for CMC are positive ones. Binance is pretty on-the-ball as an exchange, so I don't think they're going to start breaking things as soon as they begin looking around. We'll see.
