Banks hate bitcoin because they offer an alternative to the services they offer. But they no that bitcoin is going to replace the dollar sooner or later, it's just a matter of time. They're pretty scared. They don't want to get washed out. They want to continue scamming people under the fractional reserve standard.

They know that once bitcoin dominates as a currency, there will be no need for global money transfers. They were taking so much profit out of those. But now they are gone, because of bitcoin. That's because they hate it.
