Huang Yiping, deputy dean of the National Development Research Institute of Peking University, believes that the future digital currency era may be a system in which multiple digital currencies coexist. In this system, it is likely that in the short term, the respective digital currencies issued by central banks will dominate. "If there is a stable currency, I still support the issuance by the IMF in accordance with the SDR. In short, there is only one reason. No matter how the monetary system develops, a certain degree of centralization is necessary."
