I think Coinmarketcap has some requirements for the new tokens. They will add the token details once it listed on two or more exchanges which are on coinmarketcap list. CGCX is new so it might take some time.
But I takling about exchange volume and listing to coinmarketcap, not about token. Their exchane not showing on coinmarket. While GBX Digital Asset Exchange for example listed already there (in few month after exchange launch). As for token they need to have 10k+ usd daily volume for listing on CMC.
