Well while Bitcoiners are busy hating and badmouthing anything and everything that doesn't adhere to their 'Bitcoin philosophy', banks are calmly looking for ways to integrate the blockchain tech into their design, completely oblivious to the hate. The blockchain tech that Satoshi created is bigger than us, it's bigger than Bitcoin. Why not let them do their thing while we do ours and let the people decide for themselves which one they prefer?
But I think bitcoin will win in the long run as more people are becoming aware of it.While banks are adopting it in their system,still the profits goes to them in terms of charges etc. People are looking a system which is cheaper or value for their money.
