Bank are becoming afraid now of Bitcoin and it was a great concern in some countries.
Due to the previous hype about Greece +
BTC then most bank could have been monitoring the situation about this but leaving that aside, for now I could say that
BTC is not a threat
yet for bank. Unless we could have more people (adoption) to use it,
BTC will just serve as a tool for some minority
And another main factor while banks are afraid is because their investors might invest in bitcoin and bank wont have much income.
You should probably learn on how banks make their profit (Hint : use google ) . Regarding the investor, I believe there has been quite a number of people shifting to
BTC especially with the recent news of Greece and some fact that
BTC has been rallying for few times ever since the past few weeks and that serve as a good sign that some people is actually getting into this
And then I have no idea if the Blockchain technology in the banks version is a good news to their customers or not.
The original will still be better. They can observe and learn about it however in the end they will be just making another useless clone. However this is not something bank would do unless
BTC become a threat to them.
BTC has shown some potential of becoming a threat but only a few people noticed it
