I also agree with you all. bitcoin might not make disappear the bank, because the bank is a financial institution that is essential for the international economy
We share the same thought, banks will never disapper even if bitcoin become international currency. The reason is that bank isn't for money storage alone. Banks are also used to store precious metal or delicate documents which is locked inside it's vault. So even if Bitcoin control the currency, bank will simply find its way to adopt in the situation and taking advantage and earning out of it.
We don't see any strong reason behind bitcoin replacing banks, as bitcoin is too small in compare to banks and banks holds support from the society and Government, where people don't have much faith in bitcoin.
Yeah, it is really hard to believe that bitcoin is going to make banks disappear and even though bitcoin is having high value at all. Banks will always be there because all the people need banks for a country. But I am thinking that this is be possible that the bitcoin are going to be adopted by banks but they are not able to make it disappear.
