Banks will change or go under but they won't go away. They will always find some service to provide that someone else will want to buy.
I agree with that. Bitcoin may change the prospective of banking industry. Change as they say is constant. That's why every industry not only banks should adopt to the changes that come along the way. Bitcoin will sustain in its own way. Banks will find new ways to improve and innovate there services. In a way both may flourish. Bank may allow to transact bitcoins. Bitcoins on the other hand will be more reliable through the banking industry. There will always be many ways to create a product or services using bitcoins and transacting it through the banks.
