No. Bank does his work and Bitcoin do his work. No one compare each one. They are totally different.

Bitcoin and other crypto are always be a threat to the banks because they think if people truly embrace this new kind of technology the possible outcome people will switch to crytpo than using traditional way which we are saving our money to the bank. But for me bank will not disappear even if bitcoin recognize as one of the global currencies because not all the people know the existence of it.

Bank will not disappear as the fiat will not be obsolete too because Bitcoin as a currency for now is not a user friendly specially to the poor in which mostly will never know how to use it unlike fiat that even children can use it instantly so as long as money will exist in this world then the banks will going to exist too. If ever the money will be supersede by Bitcoin then i think the banks will easily to shift from fiat currency banking to Bitcoin currency banking because the banks are already used to digital transactions so for me Bitcoin is not a threat to the banks.

Bitcoin is always a threat to the payment system including banks, this is because with bitcoin then everyone can control the money and function the same as the banks so people will not go to the banks and this certainly makes the banks lonely.

Actually theres a possibility that bitcoin is a threat to banks because if the demand of bitcoin is getting better and better and have a lots of user of it or investors this will be affect the performance of the bank because of this  sudden change in demands of their own customers or investors.

Banks definetly see a strong and powerful competitor in the bitcoin since making transctions with it is somuch easier. And the more people shift to the use of bitcoin the less services banks can suggest to their customers. And that what makes them lose profit and try to find ways to prevent the bitcoin's development.

At this time, banks have no threat to Bitcoin.But banks may be inthreat in the future.Because more people are not aware of Bitcoin yet. But when people will know about Bitcoin that they can invest in Bitcoin. And the bank can earn more profit in Bitcoin. So people who invest in the bank can come down. Thereby threatening banks.

I think that will not happen, the disappearance of the bank. In my opinion, if Bitcoin develops strongly, banks are still intermediaries. Loans and investments require a bank, and paper money can not go away. They will change to adapt to it.

Bitcoin will not eliminate banks they will stay because people need banks in their daily transactions and banks also plays an important roles in business world and also to people who wants to save for their future.
