I think many people interested to use Bitcoin everyday, in fact every now and then have additional users, they're hoping to have an additional income for the future of family and they immediately made an account to make an investment of bitcoin, however while they are continue using it and enjoying the strategy of investment and then eventually they discovered the lack of securities of their account, so the people uncomfortable of that situation and it might be the grounds of the other people quit. I think it can't happen for 2022 are almost everyone using Bitcoin
* Bitcoin is not in position or power to destroy the banking system at least in near future. Period.
I don't think it could ever accomplish that actually. Why would they let that happen? As last resort, they could even create laws that will make usage (like exchanging) of btc illegal or punishable.
