Because of work, I need to live in China for a period of time. I found that China is the most widely used country for mobile payment. All aspects of life are cashless. You can go out for a day without cash, you only need a mobile phone.
1. Transportation
Whether you take a bus, taxi, subway, plane, or train, you can buy an e-ticket, just buy it on your mobile phone, and then swipe the QR code to get on the bus.
2. Shopping
Hotels, restaurants, shopping malls, even small street food shops, can pay electronically, and complete the transaction in a few seconds.
3. Transfer
If I need to transfer money to a friend, I just need to pay him directly on the chat software, no matter which bank it is, it will arrive in a few seconds, and there will be no fee.
Electronic payment is ubiquitous, which not only brings great convenience to life, but also lays the foundation for the launch of digital currency. People's ideas, habits, digital facilities, etc. prepare for digital currency.

I heard from a friend that a bar accepts BTC, LTC, and ETH payments. I really hope that in a few years, cash payments can increase Bitcoin payments.
I haven't taken cash out for a month. It feels so amazing.
Almost every country has such convenience in the last 3 years ir atleast after 2020 to avoid physical contact so they can ensure they are free from covid.
Its good to know that you are enjoying the cashless economy but do they really have any benefits?
The evil side of digital fiat economy is the inflation rate, governments don't even have to print notes, they can simply click a button to create billions.
