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.
Delay in confirmation is not a big deal as you can reduce the transaction time by adding higher fees and you will get your money within few minutes so the only difference between both of them is you cannot hold bitcoins physically in your wallet unlike real money and that is the reason people have less faith in bitcoins as they trust more something that they can hold physically.
