Binance has a good reputation, of course they will not do things that make them look bad. But chances are they could have done something in CMC on a project that would rival binance
It doesn't matter a lot even binance has a very good reputation among the crypto users and then nothing changed at all There was only one thing the only change that happened in CMC was on the deritative exchange site rank.
There was no change at all in term of daily trade volume and scam exchange sites are still taking the first position
