I haven't read all 47 (!) pages of this thread. But from a fairly short perusal of the content, I don't see anyone mentioning that banks primary function is to match savers with borrowers. Meaning that they pay a percentage of interest to savers and then charge a higher percentage to people who borrow that money. And they take on the default risk for the loans without (directly) passing that risk on to their depositors.

I'm unaware of how bitcoin eliminates those functions. Imagine a world in which we only had bitcoin. There would still be a desire for some people to save and other people to borrow. Consequently something will emerge that provides those services. I suspect it will look a lot different than today's banks, but I'm guessing that most people will still call it a bank because it will provide all of the functions that they typically associated with a bank.

You might be wrong. Because bitcoin is not a single factor baseded system. It can be modified/updated based on the future requirements. When there are more reasons to survive then it has more chances to replace bank too.

I think bitcoin will continue to survive for the long term I agree with you bitocin will not be able to replace the bank and fiat. perhaps many people would argue that bitcoin will replace the bank but I think it's all impossible. fiat and banks will always develop according to the times. bitcoin will probably be the second

i doubt that banks can ever disappear. even if bitcoin goes mainstream and be used by everybody and the price is 1 MIll Dollar.

banks are useful, we are all using them one way or another. for example the loans are a big part of banking system that is super hard thing to do without banking system since trusting another person instead of bank to take loan is hard.

The answer is very precisely and very clearly. It can be argued until whenever bitcoin can not affect the banks because they are financial institutions that have been legalized and has been accepted by many people.

The last six years history is the enough proof that bitcoin will last forever. We are talking about replacing banks by bitcoin so it is completely meaningless for pointing out the survival of bitcoin.

I think it's almost impossible as some banks start to explore blockchain, they even work with fintech startup on integrating the technology with the existing infrastructure. Unless Bitcoin goes mainstream and gets mass adoption, I don't see why it can make banks disappear.

That is only possible when Bitcoin is very famous and also more used, and that is not the case now. But I think that it is possible.
If it is going to happen, than it will happen very late, there are a lot of people that need their banks and that is really important.
You cant disappear something that is really important for the people.

According to me, bitcoins cannot make banks disappear.
Banking system is much older and acceptable system in the society.
On the other hand bitcoin still has to establish itself  among people.
Then how could bitcoin replace banking system so soon?
