Babbitt reported on the spot that on December 5th, at the "Hainan Free Trade Port Digital Economy and Blockchain International Cooperation Forum" hosted by the Hainan Provincial Department of Industry and Information Technology, founder Li Lin of Huobi Group said The construction of financial infrastructure in less developed countries and regions may achieve cornering overtaking through blockchain. For example, China's banking industry lags behind the United States. When credit card payments were popularized in the United States, China did not even have bank cards. However, due to the development of mobile payment and the development of Internet payment, China has directly skipped credit card payment and realized mobile payment for all people. In countries and regions where the financial system is not as developed as that of developed countries, it is very likely that they will surpass them through blockchain and digital currency technologies.
