I think it goes without saying the survival of countries coins relies on the success of Guldencoin, Aurora failed badly , if Guldencoin gets into top 20 then all other country coins will get more investment. I am currently supporting Sterlingcoin and with all the effort and dev that has gone into that coin the price is terrible compared to what it should be.
I have purchased some Guldencoin as all country coin fans need to support it so other good country coins get more support.
