Banks might come up with their own version of a regulated bitcoin like product. Since banks have been around and people see them as trustworthy companies, people would think that their money would be safer there and they would have options to choose from in terms of what they'd like to invest on.
I agree with this..banks have survive years..Maybe because of adopting to new situations...So I think if bitcoin would go mainstream, banks would also think of what they can offer to counter and slow down bitcoin, so probably adoption of new technology like blockchain would be a great idea for banks...
Maybe they will adopt to blockchains technology. But I don't think banks will disappear. We are still using banks to exchange bitcoin to fiat. And I don't think exchanges from this two will ever disappear. Bitcoins growth will always be measured by how much it is worth in fiat.
We do not need banks to exchange the bitcoin to fiat. That can be done by the existing exchanges so far.
Agree with your idea bitcoin cannot make bank dissapear because bitcoin still relays to banks so we can use it physically and bitcoin is unstable for today and banks are safest atorage than wallet.
