Young people should be full of energy. Twenty years ago, in 2006, Ma Huateng mentioned virtual currencies in "Challenging the Authority of the Renminbi," where the concept of virtual currency exchange and virtual asset economic models first appeared. At this point, virtual currencies had nothing to do with blockchain. Two and a half years later, on January 3, 2009, the Bitcoin genesis block was mined, marking block height 0, and the blockchain began running. Bitcoin's true birth signaled the beginning of the era where virtual currencies entered the blockchain and Bitcoin dominated.
