Bitcoin breaks through 20,000, will the U.S. dollar be expelled?

The emergence of digital assets will threaten the U.S. dollar's dominant position globally, but overthrowing the current global reserve currency dollar is not easy. After the end of World War II, the Bretton Woods Agreement formally established the U.S. dollar's unchallenged dominant position in 1944, since then the global monetary system has been centered on the dollar. While the United States controls the world's reserve currency, it has also enhanced the country's already enormous geopolitical influence and its ability to run massive deficits at low cost. Today, an increasing number of experts believe that the dollar's hegemonic position may be declining.
