Bitcoin price doesn't depend on bank's minds. If they all hate bitcoin, why most of them bought crypto-exchanges, or cryptofunds. On mass media they talk that they hate bitcoin but after that they buy it.
That is there strategy to encourage those panicking people to sell their coins and taking advantage on it. Crypto is now a huge market and of course many were having interest towards these.
No its not just a strategy but that is true . many banks do really hate bitcoin because they think that bitcoin is a big threat to their business . they see that people are using bitcoin as an investment . sooner or later , people will refrain to use bank because they cant earn huge interest on it and they rather switch on bitcoin . not only they can earn big return , they can also ensure that their money is safe because they hold their own wallet .
