We wanted to inform you that we're listed on CoinMarketCap as "Untracked Listing"! After long talk, we are finally here! But at the moment there is no data be found and we're not listed on cryptocurrency list yet. But Gravium can be found at Search in CMC.
To be fully listed in CoinMarketCap, we need a 2nd exchange (which is listed on CMC too) and we've currently searching exchange. I've already mailed to 20 (and increasing) other exchanges so far. 

But most important: The most of the part by listing CoinMarketCap is done. There are still some work left.
