I think that how Bitcoin has become popular, it can be understood that Bitcoin Banking can start. However, if you can build confidence in Bitcoin in Baramon, it will be very good. Because everyone will invest Bitcoin. The demand and popularity of this will increase. So, in future, Bitcoin's banking may be launched, maybe maybe.
I don't think so , the demands of Bitcoin don't come from the people who are using banks or bank services, it's all coming from the users that can't use the bank services so it's hard for Bitcoin to replace the bank in anyway.
