Virtual HKD (VHKD), a digital currency anchored to the Hong Kong dollar, reshapes the way users consume with a constant value-preserving payment experience. VHKD is a digital currency asset issued by the international digital currency group VDAC (Virtual Digital Asset Corporation), which was first issued on the IDCM exchange. VHKD adopts a more reliable audit and margin system to ensure the stability of the value of VHKD; VHKD has multiple advantages such as stronger risk avoidance capabilities, faster sending and receiving speeds, and rich offline application scenarios. Based on the same concept and design, VDAC simultaneously issues VUSD, VEUR and other digital cash anchored with fiat currencies.
