The question is should we be happy or stay alert because of some foul play?
I think we can let the banks do their jobs and if they want to make the blockchain as the competitor, we cannot do anything. But the banks will know that they have something that they don't have compared with the blockchain. And soon, the banks will realize that they need to integrate their system with the blockchain itself. We should be happy and stay alert because with doing this, we can prepare if something bad happens so we can save our assets and our money and we don't have to get the bad experience.
