For me, it can happen, but the percentage on digital money equal to a cashless society is very meager. We all know that there is only a few establishments that are accepting bitcoin comparing to that establishment and companies that are accepting bitcoin as payment. Also, the acceptance of bitcoin is still meager even it is accessible and expensive. Maybe in the future, digital money is equal to cashless society if bitcoin and another cryptocurrency become legal and the acceptance grow.
It is possible to happen, but we need more security for our own money. We hear a lot of news regarding in hacking. We know that the main important reason why bitcoin is not yet popular because, it doesnt have enough security for our own money. We need something for our safety and security of our own virtual money.
