Bank alway hate bitcoin and bitcoin is their competitor, why should we care about bank?
If the demand for the bitcoin or other coins is continuous, we dont have a problem with it. As long the holder and the investor of the bitcoin or altcoin dont use them on the illegal activities like money laundering and corruption. I sure that bitcoin will never end with the government because the reason of some government they ban the bitcoin because of the criminal activities and the problem to how they add income tax with it.
