It would be too impossible for now because we all know that the government relies on banks. Lots of people also trust banks more than other currencies or modes of payment because it's traditional and tested. However, I believe that cryptocurrency and banks could collaborate in the future. It only needs more time and adoption.
It's true that if we talk about the current conditions, it looks like the Bank will still exist and maybe it will forever exist.
indeed at this time crypto is already known by many people but I don't think Banks will be replaced,
I'm sure the collaboration between crypto and Banks will happen although we don't know when for sure
Don't be too sure that banks will die and be replaced by crypto, it seems that this is impossible. Banks will always exist because the government's
way of controlling the people's finances is through banks. After all, the majority of countries in the world still prohibit crypto as a means of payment,
meaning that crypto is indeed restricted by the government. Moreover, there are still many people who live in areas where there is no internet
connection, therefore banks are still very much needed. So I agree with you, it is likely that Banks and crypto will co-exist and complement each other.
Even in my neighborhood there are still a lot of people who don't know crypto, so like I said it's impossible for crypto to replace banks.
