On my opinion base on my observation bitcoin is the new era of currency because formerly we use of barter treading and that time people didn't use money but now we are using money by means of payment in form of coins and paper money and also now there is a bitcoin, it is a digital money discovered and exist in this word and accepted by means of payment. Bitcoin is the most efficient money right now.
