Meng Yan, vice president of CSDN, said that Facebook has a dispersed user base around the world. It has no better choices and can only learn from the idea of blockchain and cryptocurrency to avoid launching global payment networks in the traditional way. Facebook cannot establish a global payment network through traditional methods, because traditional methods require a license and prepare foreign exchange reserves at local banks in each market. Meng Yan believes that this method may not be applicable to Chinese payment companies because they come from a single economy that uses the same type of legal currency. China already has a well-established payment and settlement network, and it may not be necessary to use encryption-stabilized coins at present.
