no, because there will always be those scared average joe, that will rely on the bank, no matter what new tech you have, you need plenty of new generation to remove those people
it's the same as right now there are still people that refuse to use credit card or new services...
That's right but eventually, one day it can make the banks disappear as the new generation takes over.
That's a hard mission to do dude, as long as this world is controlled by the government it will never happen that banks will be replace into something they cannot control. Let's be realistic, bitcoin is not even a threat for them now, they see that bitcoin market is growing due to increasing adoption but what they want to do to us, is they want to control us to comply with some of the law which will give them financial benefit.
