CMC power is so strong that coin developers list their coin on CMC before adding it to an exchange.
I am pretty sure that the quoted part is not correct. I remember reading about their listing requirements in the past. To be listed on CMC your coin has to be publicly traded on an exchange with a decent daily trading volume. I am not sure of the volumes but the info can probably be found in CMC docs.
If I am correct, it is not requiring too decent amount but $50000 volume within 24 hours only. Projects usually list on an exchange listed in CMC and manipulate the market to increase the volume to list them into CMC. $50k is too low in my opinion and they should change it.
