I think you don't have the ability to satisfy the criteria of the CMC, while other exchanges with no volume have already listed CMC. Maybe there is something that you need to satisfy them otherwise, it is impossible for you to get listed in CMC.

I tried listing a coin there a few months back, it was a nightmare, they also gave our name to another coin's url (by mistake ,they had a totally different name) . The only thing that helped back then is take screenshots of all their mistakes including correspondance and posting it into an article that got picked and had like 20k views. Only then all the problems magically disappeared and the coin got listed.

Now I'm taking an interest in a new exchange called mintME.com that acts as a crowdfunding platform and it's in my best interest to get it added there but I know how shittty CMC's customer service is so I'm not holding my breath.
