We all know how risky bitcoin is. Let's imagine the most riskiest money deposit situation.
What do you think guys, will this moment ever come and banks decide to offer us Bitcoin deposits (e.g. fixed profit on 1 year deposit and etc). 
This can be very, very profitable for banks if they make correct decisions.
P.S I don't mean freebitco.in's offer of holds on their wallet. I mean if official banks ever offer us this service.
 As far as I know, some banks already offer such services. For example, in Russia, some banks offer to invest in the crypto currency. But I do not know what exactly the implications of investing. I consider this a significant step towards the legalization and distribution of crypto around the world. I think that the future lies behind this. But can this be an attempt on the part of bankers to seize the entire crypto industry? Is it dangerous?
