Paper money is disappearing. Paper money is disappearing? What impact does the central bank's preparation for digital currency have on life?

This sentence is alarmist. The disappearance of paper money is feasible in theory, but not in China, at least in the last decade. In some small European countries with developed economy and perfect infrastructure, such as Norway, Finland, Luxembourg and Belgium, it is very difficult to realize paperless trade, not to mention China, a country with different levels of development.

It is the general trend for the central bank to prepare for digital currency, and it is feasible to replace cash transactions with digital transactions in theory and practice. Actually, it's true. In the future, we will use digital currency more than cash, and digital currency payment will become the mainstream. However, mainstream encrypted digital currency such as Bitcoin and Litecoin will be marginalized. Similar to European crowdfunding, there will be more digital currency asset certificates, but the life span will not be too long.
