I don't think not all bank hate Bitcoin, in fact that there are many banks around the world defend and have corporations with crypto currency industry. There are many banks that are not ready to adopt crypto currency in massive. Then, peole think that this is like rejection of bitcoin.
Maybe some but not all... The entry of crypto currency into the market world create a lot of uneasyness, some fearful about on what to become of the Banking Industry once crypto currency digital transaction is globally accepted? Some are not open for crypto tansaction, we've already seen or read that some are against crypto. With this apprehension create a lot of issues confronting Bitcoin today. Yet. Some banking institution are opening and embrasing the usage of Bitcoin. In due time once all the concerns are resolved are address globally, then we can see the fears will die down...lets wait, Bitcoin is our future crypto coin in the making.
