The world is revolutionizing day and night and every day new inventions are being brought in. With currencies, there have been several revolutions dating back to the days barter trade was the norm, there came precious stones and other metals. Coins came in and paper money also came in. As we were still using these, electronic transfers and credit cards came in. Now we have electronic money and crypto-currencies. One fact is that apart from barter trade, the other forms of exchange although some of them are not used frequently. I therefore believe, that the paper money currency might decrease in it's usage but will not disappear. The future of paper money is there but it is bleak.
