It amazes me this coin is still not on exchanges. Considering how many places accept it as means of payment.
Will it ever or is it the purpose to create some sort of ecosystem with a fixed value?
Good question.
If not we will have to travel to Catalonia to spend croats.
If it becomes popular, you will find a way to sell them to someone in Catalonia, be it on an exchange, ebay or whatever.
Btw, there is an exchange that trades croat, though it's not a popular one:
