In every business it's the same. When new technology comes up the existing businesses will evolve or die. And obviously new businesses will also rise strong.
Same happened with mp3 and music industry...
I agree. I think more than dying, banks would try to take advantage of the cryptocurrency wave and make sure to actually get their systems adjusted with the cryptocurrency market to accommodate it. It's a big market after all, and surely, if they would do that, then it would surely help their businesses grow rather than just stick to the traditional means of doing business. Banks are money-generating entities after all, and they go after booming business that may innovate the business sector.
