Few days ago a friend asked me this questions. But i cannot understanding that how to i give him answer. At last i said him that, bitcoin is an online currency. Only this currency used in online marketplaces. It is not possible to use it in offline marketplace like offline currency.
But what is your best answer of this question?
Well bitcoin is a digital currency so it cannot be use like fiat money. One of the difference of fiat and bitcoin currency is that fiat can both have digital and physical form(coins and banknotes) while bitcoin doesn't have a physical form. Another way to say digital currency is electronic currency. So it can only be use if you have an internet connection.
