Uniquely, bitcoin will not make the banks disappear. Just the time will come when all banks will understand that without the use of crypto currency they can not exist, therefore they either adapt or close. Well it's obvious, because you need to adjust to progress. Of course, the cryptocurrency is changing the entire financial market.
I somehow agree on this. The telephone companies didn't disappear when the mobile phones took place about a decade ago, same as the USPS when emails took place in the 90s... I guess the banks would join the bandwagon once they realize that majority of people are patronizing it.
