I don't think we will see in our lifetime that bitcoin will indeed trigger the collapse of central banks.
I understand a lot of people are very happy with this new invention in digital currency.
But it is too early to think that it will significantly impact the traditional way of banking system.
Let us be grateful that some banks are already accepting crypto but replacing the local fiat, I don't think that's gonna happen in the coming years.
Your words and thoughts is kinda pretty similar to mine and yes, you are right. That's the point, in my own thought i also wouldn't think that bitcoin would trigger the collapse of the banks.
You have to consider the governments first, i don't think that they will let that happen and i know that they wouldn't allow it either. We are already used to the banking system and a lot people prefers banks over bitcoin but then again banks will never collapsed.
It's up to the government itself. If they don't allow bitcoin in their country then the banks would stay still, standing all over the city and continuing to grow and develop. Also banks are in a huge demand. Besides, if ever the banks collapsed, i don't think that the citizens will be okay with it. It needs a lot of adjustments to adopt a new change.
