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.
yes you are right becoming the partner with the development of Bitcoin and banks will connected together is bright idea because if each and everyone facing problems with the development then people will affect the changes so if they are connected together only we can made the future to be a successful way.
