Today is not a country , but it have a lot of independence from central goverment both economically and in law making, also the majority of the political parties currently on regional parliament are pro-independence of spanish central goverment.
But the most important thing is the national feeling of the people of Catalunya, the vast majority of people have this feeling , and this is a fact, historically a majority of Catalanya people have a feeling of be a nation itself.
In this climate of economical crisis, and the central goverment making mistakes every day, acting with represion against the people over the entire country like a non-democratic state, this coin have a great future.
On the other hand maybe the devs are only trying a brick and mortar heavy dump, i dont know because i mostly dont participate on forums. If this is true , its a pity becuase on a fundamental analisys the coin can be a success.
