Personally, I think it is only a matter of time till real banks start offering Bitcoin related services (e.g. deposits and loans)
Nah, can't see this being a realistic outcome in the future.
Mainly because of the fact that Bitcoin is something banks can't verify the source from. In these times every decent amount of money that people deposit will be subject to a far more drastic protocol. Governments are constantly raising the bar with their ridiculous policies in an attempt to stop money laundering and the financing of terrorist groups.
This argument doesn't hold
When you bring cash to a bank office in order to open a deposit account, do they ask where you got the money from? I guess they don't unless you bring a sack packed with Benjamins. In this way, as long as you provide all necessary details about your identity (which you would have to reveal in any case), there shouldn't be any particular issues with opening a Bitcoin account in a bank. And then you just send bitcoins from your personal wallet to a wallet linked to your account in the bank very much like you make a wire transfer from another bank
At the time when you create your account at the bank they ask for the proof of source of income and after that when you deposit your money they calculate them according to that source and when you have some income to that account something of different value or from a different place rather than expected according to your source of income then they start investigation. That is the way of banks in my country.
