That will change the whole payment system from the traditional payment system into a digital payment system.
But I think we already use the digital payment system in this pandemic because many people use their digital fiat that integrated into their mobile phones to pay something, so I think we already transform into a new payment system.
Maybe the real money still exists and can be used for payment, but the cryptocurrency can give another option to pay for something that we buy.
But I think we are still far away from that because the cryptocurrency is not used for the payment system until now.
At least, many countries still use fiat money to pay for something.
If cryptocurrency becomes more popular than today, and many countries are trying to integrate their system with blockchain technology, maybe the new era of the payment system will start.
We will see a new change in all countries.
