aantonop is correct in that the banking sector is setup for major disruption soon.

I have a technical background and started working in Banking a few years ago as a product manager for Trade Finance products for corporate clients. One of the first questions I asked was why don't we do something around Digital Marketing? The answer was that the sales processes are different etc and its only about direct meetings with the clients... its very difficult to change the culture and behavior of line personnel in conservative businesses.

Bank products are very abstract, in the sense that the products are not physical things (for example like a car). In the end it is about 3 things:

1. A risk model (Mathematics) to balance cost versus revenue
2. IT systems and processes
3. Trust with the clients

Trust is currently the main competitive advantage that old institutions have versus new competitors, but technology like block chain and smart contracts will be a serious challenge in this regards.

Thank you for reading my comment, I am a new user and this is the first post I do. I finally took a dive into the world of crypto-currencies about a month ago so still learning, and that is how I found my way to Steemit.
