Cant see the difference of this "bank" from common crypto exchangers that exist in many cities all over the world already. It gotta be a good market move to call it "Bank", sounds so cool and important 
I see your point. I likewise think that there is no need for bitcoin to have a bank because we already have a wallet. A wallet where we can have access anytime we want. A wallet where we can transfer payments, pay our bills, and even paid some person. We can invest directly if we want. If we store our bitcoin in our wallet its price will likewise goes up.
but also let us not set aside that not all things are can be paid thru banks or thru online banking , like if you go to a groceries even you have a huge amount of bitcoin on your wallet you cant used it because it is not adopted yet you need to transfer your funds to a bank before you can purchase anything from a small business or even a large one.
