Sure, that's the reason to care for the unbanked population as it's a new market for Swiss banks. However, the number of unbanked will never grow significantly in Switzerland or nearby. If it starts to happen the state will help and it's the only one who really needs banks. Somehow I don't worry about banks, they will for sure find a way. Swiss is the great example. They have only few hundred years of financial stability, mainly thanks to the fact that they accepted everything above a certain amount... why not bitcoin? (Nice topic BTW)
