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.
in my opinion all possibilities can happen no one will know for sure and the possibility of the bank will adopt an economic system used in crypto currencies or crypto markets
of course not. bitcoin and banks have different principles. however, sometimes there are some people who associate this. however, banks are always used to protect the assets we have, as well as making fiat, or borrowing. I think there are a lot of limitations that Bitcoin can't overtake the bank.
