Okay, I see now why the coin is not listed on Coinmarketcap.com, Graviex is not one of the exchanges supported by coinmarketcap. There are few requirements, but once those are filled you can send in a request to coinmarketcap.com to have Pawcoin listed. Below is a link to the FAQ and the link for the request to have Pawcoin listed;

1. FAQ page, for requirements:   https://coinmarketcap.com/faq/
2. When needed requirements are met, fill out the request form: https://coinmarketcap.com/request/


You can still look into having Pawcoins Masternode listed on Masternode.pro, but without the coin being listed on Coinmarketcap.com, it will only show up on the Simple Statistics tab;
