I don't think will happen, the bank will still be, because also governments wants banks, is the way how they control money and they know faster how much money are on market and how much money are in a bank. Only if governments will want that banks to dissappear and adopt crypto then crypto will replace banks, but this will not happen in my opinion.
So far it is, we can see that what the government can offer are the things that the people accepted, but as we can see, Bitcoin is not just for some random stuffs such as investment, it is for a lifetime, a new form of transaction, just like in
vegas casino we can do betting with the use of bitcoin without even minding going to casino. This is how the Bitcoin works, how it can help us in the future.
