(1) SO WHY BANKS ARE REALLY AGAINST CRYPTOCURRENCY? Cause the volatility of cryptocurrency markets are concerns over security and regulations. They've made many banks cautious about involvement in the crypto space. Some banks have even banned the use of cridit cards for purchasing cryptocurrency, reflecting their hesistancy to embrace the emerging technology full. If only the cryptocurrency are ready to make a good terms with the banks.
I don't think bank have any problem against cryptocurrency. Goverment makes the rules and banks have no choice than to do what the government wants. Banks not trading cryptocurrency, exchanges delisting fiats, and so on, decisions like these are made by government and not by the bank. The reason for all these is because the government sees bitcoin as a threat to the traditional currency just because they can't control bitcoin and they try do everything to frustrate investors from using Bitcoin .
People are aware of how Bitcoin is a good asset to invest , unlike the fiat hodling it for a longtime can't yield good value instead it depreciates in value. The government thinks bitcoin is making people to lose interest not to save money in the banks. If government csn fully accept Bitcoin I don't think their will be any bank policy that will go against bitcoin.
