Golden Finance reported that Wu Jinduo, a Ph.D. in economics, wrote in the Hong Kong media Ta Kung Pao that the value of cryptocurrency is still measured in US dollars. As a decentralized payment method that is different from the traditional one, it is a supplement to the payment function of traditional legal tender. . From this perspective, cryptocurrencies share some of the monetary attributes and characteristics of the U.S. dollar. Since cryptocurrency is not yet a pricing currency, nor is it a global legal reserve asset, the basis for its value realization is still dependent on the US dollar, legal tender and gold, and its stability and popularity are far less than the US dollar and gold. When there is excess liquidity in the U.S. dollar, or when the U.S. dollar is at a serious premium, cryptocurrencies are expected to become a reservoir of global liquidity. This process is led by the market, rather than central banks and sovereign institutions, so cryptocurrency is a major global asset class and a carrier of wealth for residents. Public information shows that Wu Jinduo is a part-time researcher at the Financial Research Center of Fudan University and a senior economist. He has worked at 985 universities, Shenwan Hongyuan Securities Research Institute, etc.
