Thats the fact, bank always try to find way to make vryptovurrency looks bad.
I think banks are afraid of digital currency and they should be because with the use of digital currency the use of banks will reduced slowly and gradually because keeping your money doesnt cause any serious charges or tax while bank does, so thats why people use digital currency rather than keeping their money in banks. Banks can survive along with digital currency but the fact is that its use will be reduced by the people.
