Difference between bitcoin and real money for me is confirmation process as its today. Real money doesnt have this. However, bitcoin always superior and we can make choice to invest.
yes it is true, bitcoin process sometimes, takes hours or days before we can get ur money, while in banks that having a real money, it take only a minute to withdraw it, but for me , i still choose bitcoins over that real ones.
One should also not forget that bitcoin has many advantages. For example, deflation and anonymity. This is not if you use real money.
