Banks of course will still exist but they may sound very irrelevant in the next few years specially when one day they most of the government department are already integrating with Blockchain technology. Bank will be there still and will still exist the only difference is that they will soon be using blocckchain too just to get along.
Right, banks will still their no matter what not unless they will not adopt new system. Well a lot of banks now are using blockchain technology with the system of ripple i think and this is a good strategy to use for a better system. I believe all banks will use technology in the comings years.
