Dr. Wu Jinduo, an economist, wrote in Hong Kong's Ta Kung Pao that the measurement of the value of cryptocurrency is still based on the US dollar. As a decentralized payment method that is different from traditional fiat currency, it is a supplement to the traditional fiat payment function. From this perspective, cryptocurrency has some currency properties and characteristics of the US dollar. Since cryptocurrency is not yet a pricing currency, nor a globally recognized reserve asset, its value realization is still dependent on the US dollar, fiat currency, and gold, and its stability and popularity are far inferior to the US dollar and gold. When there is an excess of US dollar liquidity or the US dollar is severely overvalued, cryptocurrency is expected to become a global liquidity reservoir. This process is market-driven, rather than by central banks and sovereign institutions, making cryptocurrency a type of global asset and wealth carrier for residents. Public information shows that Wu Jinduo is a part-time researcher at Fudan University's Financial Research Center, a senior economist, and has worked for 985 universities, Shenwan Hongyuan Securities Research Institute, and others.
