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?
Blockchain was only created to transact financially without the middle party like banks and other financial institutions. This will free you from centralized policies that generate big fees and other unnecessary procedures. But other processes of banks cannot be replaced by blockchain. So even though blockchain is developing, banks are still here to stay.
