I think it needs proper marketing for this to have users from those 10 countries. If it will be mainstream in those countries then this project can be big. That is a big IF though, hope that those countries are not the small ones.
Even if the countries are small 10 of them is not small number and that's a lot of possible new users and a good base for the project. In future that number of countries could get bigger and bigger if it all works well.
