I am sure that banks will not be destroyed, because banks play a big role in a country and even in the world, so it is impossible for banks to be eliminated even in the decades to come. in China alone crypto is eliminated how crypto can take over banks.
The most probable and reasonable thing is that crypto will be bigger than it is now, but it cannot replace the role of banks in the world.
I agreed with you, banks would do more of peripheral jobs but unreplaceable, probably there major role is for transactions between two anonymous crypto traders selling of coins and sending fiat to the buyer vice visa however I think a lot of crypto enthusiasts will prefer to hodl their coin as a store of value rather save it as fiat in the bank thus banking would be less attractive to people in saving money because the rate at which crypto adoption is going is in leap and bound.The most probable and reasonable thing is that crypto will be bigger than it is now, but it cannot replace the role of banks in the world.
