Bankers hate all who have their own money and do not keep them in their bank, even other bankers.
Bitcoin does not need a third party to provide transactions, so it automatically becomes the enemy of the bankers, because it deprives them of their income.
This is the basic principle of decentralization, and for that we love Bitcoin and other cryptocurrencies.
I agree, I think the banks can see that their future is gonna be bad is the cryptosystem is gonna continue to be applied in every country, they would get lesser and lesser money on their hands and soon enough will start to shut down. I cant blame banks for feeling like that, the cryptosystem is just so convenient, you can use it any where and anytime as long as you got internet.
