Third, any sovereign government provides digital currency supported by digital technology. Because of the trade war between sovereign countries, in the future global digital financial market, it will not have global financial impact, but some countries will use their own digital currency for domestic demand, which is essentially the digitization of traditional paper money. Fourth, when end users around the world, whether institutions or individuals, choose to use global digital currency for settlement, a monetary organization that regulates the global digital currency transaction order will naturally be born, but cannot change the essential attributes of digital currency. Any sovereign country can apply to join this international organization. Fifth, the future digital currency circle will be a special fair competition industry, full of opportunities and risks. When the growth logic and credit value of any digital currency reach a certain level, it is likely to evolve into a continuous situation. Sixth, with the advent of the global digital financial era and the continuous regional re-emergence of traditional financial centers, highly speculative derivative transactions will present different results. In summary, the advent of the global digital financial era. It is based on two conditions. One is that the credit of the currency of quasi-states is getting worse and worse, and the worse it is, the more water it will be. The Jinying class blatantly uses currency to speak and reap wealth from financial speculation bubbles. Since the beginning of the 21st century, everyone can see what is behind the cooperation and conflict of interests in the global market? To a large extent, it is a conflict over the currencies of sovereign states, which is hailed by some students as a currency war. Any major country hopes that its own currency will become a substitute for the global currency, and the hegemony of the US dollar has limited the memory space of many countries. Therefore, if with the acceleration of the process of globalization, internal operations will not be intervened and controlled by capitalist countries, cannot be taxed, and can support international transactions and calculations. A global digital currency can guarantee the fair benefits of the free market economy. Second, the new generation of information technology and mobile Internet provide technical support and credit support for the above-mentioned items. Technology $BTC
