As far as my country is concerned there is no bank that accepts bitcoin and I don't see it happening even in future as the government of my country will never allow that to happen.
Here in my country has almost the same situation, the central bank gives warning to the people that we should be warned upon using bitcoin. But right now, it seems that they are willing to eat what they've said before because it looks like they are planning to adopt bitcoin transactions with the bank.
in my country the bitcoin is considered illegal, the government and all the banks doesn't accept bitcoin but they didn't give any warning to people about the use of bitcoin, i think the popularity of bitcoin is not very much in my country that could be the reason that the banks does not accepting it but if everyone know about it in future then there is possibility that the banks will accept it.
As you mentioned that bitcoin is considered illegal to your country, that will affect it's popularity and people will not have any way of thinking to use it because they will be different to others because for declaring it as an illegal currency. But once your country starts to endorse it to the public, the popularity of it will grow.
