bitcoin is really becoming stronger and stronger, and going is not going to disappear any where, we will use it for ever and will get benefit from it.

Exactly, and if they really reach the point where they think they would need to do something else as the banks wont run anymore, they would probably make their own coins or something which will be in their control as they would not be able to have any control on bitcoin i guess.

Banks will never disappear, because there will always be people who will depend on the bank, no bank, fiat could not exist, because the bank is the only one that creates the money, so there is no reason for banks to disappear.

There is no way that banks will gone or disappear if banks will disappear it can affect also the price of bitcoin all everything online related in fiat will gone.. banks are the main source of money why we have money and that is why bitcoin can exchange into fiat because of banks. they are perfect couple just like you said.. and yeah i believe bitcoin is just alternative payment processor or investment

The power of bitcoin is big, but not big. I think in the end banks will develop their own bitcoin and force it onto their customers. Problem is they must make it way cheaper else people will still go with bitcoin.

The people would not leave banks with the establishing of bitcoins, as the bank do not only for saving or investment of public fiats. Nowadays the banks have a major role in state finance also. All the state finances are controlled and regulated in state banks.

The bank does not create money. The bank simply makes sure that your money is secure. I wonder what would happen to banks when people start to not use fiat any longer. It will only lead to financial loss when people aren't interested in using their service anymore considering the fact that they have a wide workplace. They spend a lot of money paying for all of those employees and if no one's using their service, they would have to remove some employees until eventually shut the whole bank down.

Bank will never disappear, people will still using fiat till the end of the world no matter what happen with btc. Bitcoin is just a crypto currency that will never replace fiat currency. I have no doubt about it

There will come a time when solar flares disrupt the electrical grid and electronic money will disappear. Fiat will go down at the same time, because it is electronic money.
