I think it would be useful to have a bank that would provide safety to trading with cryptocurrencies.

So that it would be as easy as it is nowadays to invest in stocks. Just transfer from your normal deposit account to your trading account, instantly be able to use it, and have access to the market through that account.

If that would be possible, I would use that instantly. It would make the entire process so much easier.

A project of that magnitude would be difficult to pull off though.
