On December 14th, financial writer Xiao Lei wrote that in the future, who will be bolder in the digital currency field and who will better use digital currency to complete the transformation of the financial industry and the transformation of the international financial discourse right? We have to wait and see. . The ATM machine was originally invented and used in the United Kingdom, the world's largest financial country, but in the end, the United States completed the transformation of its own financial system using the ATM machine, and eventually surpassed the United Kingdom to become a financial hegemon. It is very interesting that the blockchain technology that carries digital currencies was originally born in the current financial hegemony, the United States. In the end, whoever can use digital currencies will have a greater advantage in establishing a new global financial system. The boss cares about keeping his position, so he will suppress some of his more threatening technologies, and the second child will generally be more likely to accept and use new technologies to build new public systems and attract more supporters.
