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.
