Digital currency is the in thing now. Many countries are opting for cashless. This means that the use of fiat currency which is fraught with theft. The use of credit and debit cards is the first step in digitalization. With the gradual introduction of bitcoin and altcoins, total digitalization is the future economy.
I think our world is progressing, so are the applications and products. But somehow, there are still people who become the basic way of paying because they get used to it. Or maybe, those people have not introduced a new payment method yet. We can wait a few more years and this world will be a society without cash.
digital money is now used in every part of the world. This is very convenient in the sense that you do not have to carry a bag of money just to buy very expensive items. Just swipe or scan it, already paid. Our new era is needed to have new innovations for advancement and for that to be a mixture in our current high-tech world.
Paypal, Debit card or credit card is not the real digital money because all of them is being backed up by the Fiat currency. The only pure digital currency is the cryptocurrency which is not being backup by anything and has its own value. This form of currency will be more and more used as the time passes by.
