Blockchain-based banks are definitely coming to the market in 2018. Crypterium, which advertises itself as the world's first crypto bank has recently concluded their ICO with over $50 million raised.

In addition to this, I think we see other players in the financial services/ crypto- space expand the number of services they offer to help meet customer needs; i.e. many companies issuing debit cards to spend crypto in the physical world, etc.
