Typical banks, will they ever take Bitcoin seriously?
Probably never. BTC is a major competition to the banks, if btc becomes a major everyday currency like fiat, then banks will go out of business. So obviously they will never support BTC or take it seriously.
It comes to disrupt the financial system of the centralized bankers. So, a lot of the country or majority of the country that has controlled by the bankers will against the crypto or something else that was not following their step. Bitcoin will never become a fiat. This time most people are happy to investing in the bitcoin as their investment.
But remember the presedent of the IMF already made a serious statement regarding the bitcoin because the possibility of the bitcoin become the major disrupt to the centralized economic.
