The current trend of blockchain is very high, couple with it's ability to execute millions transactions within seconds, few transactions cost and no third party is require or paper signing. All transactions recorded and kept open, taking alway cross border and languages barrier, excellent in e commences. So many features to change the world. My emphasis is can blockchain has the capacity to replace bank?
I think it can't replace any banks till this sytem won't be able to rule the world in my opinion, because banks are everywhere, and they're working with government machine much more closer than blockchain
