On November 22, Zhu Min, dean of the National Finance Research Institute of Tsinghua University and former vice president of the International Monetary Fund, said at the "2019 Innovation Economic Forum" in Beijing, "China does not need to compete for the issue of when to launch digital currency. 1. Mature technology and mature policy framework are the most important. He also pointed out that the introduction of digital currency by the central bank is the future trend. If it is not launched, it will face two kinds of pressure. One is pressure from the market, cryptocurrencies such as bitcoin, although not sovereign currencies, are actually eroding the territory of sovereign currency. The second pressure is that when considering the issue of digital currency, especially in small countries, if the digital currency is not issued, the sovereign currency will be marginalized.
