No I do think this can happen in my opinion this is highly unlikely but we will see what is gonna happen of course because the fact is that its not to predict.
The banks are controlling the world and they have a lot of power that is why I do not think the bitcoin do it.
Banks will always serve us even bitcoin will skyrocket, there must be a reason why the government put bank and that is to safeguard our assets if we prefer to deposit it, big businesses does not keep their money themselves, they put it in the bank.
