I've added CAPTcoin to the voting list at C-Cex. Right now it would take about 200 votes to get added. If the community rallies, we can make it happen.
https://c-cex.com/?id=voteEDIT: You can also pay for votes. Only 0.20 BTC would put CAPT at the top of the list.
If we get enough to donate something small like .005 we could get there in no time.
