There are some people in crypto community who are believing that blockchain will replace the current banking systems. However, all their basis is the concept of blockchain that hasn't been made to its potential. This is my reason why I believe that blockchain won't replace banks.
Indeed, banks is big institution and have a lot experience in finance industry. I am believe banks will not death but they will adopting blockchain for their service because blockchain is eficient technology that can save a lot cost. Bank already survive in any condition and i am believe banks will survive too this time
