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 the bank is still functioning well in conducting local transactions, because if we exchange crypto with conventional money, we need a bank. Blockchain helps to conduct international level transactions at low cost.
