Bitcoin and fiat currencies operate in two entirely different settings. While bitcoin operates with decentralization, fiat currency is centralized, so I doubt that banks can directly handle your cryptocurrency wallet. What should be important is buying and changing your bitcoin without any problems.
The goal of the blockchain was to no longer be dependent on banks. So in my opinion this information is false, the bank will not be involved in what is happening. It is true that the banks are trying in one way or another to find a way to be part of this blockchain.
