I think not all banks are hates bitcoin. In my country, there is no bank that hate bitcoin. Because the bitcoin itself not popular here. But when bitcoin popular here, i think banks will hate it.
That's why the bank in your country doesn't hate because they don't know about it and your fellow countrymen has lack of knowledge about it.
So banks doesn't have a reason to hate bitcoins because when they see the good side of bitcoin that can benefit your coutrymen.
For sure, they will hate it and becomes a threat to their business.
Banks are hating the currency because it will be not used that much and that is bad because they cant earn more money with it so that is really bad.
And they see that people that is using more Bitcoin and that is nice for the currency itself, but it is still hard to predict what will happen later with Bitcoin.
