No one bank accept bitcoin in present time because bitcoin is digital currency and it can be use use just for online transaction and i think it can be possible that bitcoin accept in bank if bitcoin become in physical shape then i hope that we will be able to use it in any local shops .
And not even in the future, I am confident with that. It will only happen if the government can control bitcoin but the fact that they can't it will always be the same bitcoin and crypto world will always exist.
