Just like the internet came back then, Digitalization of the world is coming and nothing will be done to stop it
Indeed, we cannot stop innovation because it is inevitable. Just like internet, digital currency will become powerful that can be one of the way to make a payment for any kind of transaction but I don't think so that it will overtake fiat because, fiat is still more efficient yet preferrable of people. Therefore, digital currency can only be as an alternative for fiat transaction.
