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?
crypto may will not wipe out banking system but one day maybe it will be regualted by the banks for the fast and secure transactions..it is not easy to make baks disappear there is still need of banks like to store the money bearer checks, cross checks etc
