为什么美国全面转向加密货币（比特币+稳定币），而以中国为代表的非美国家全面转向黄金？

Group 1 - The core argument is that the U.S. is shifting towards cryptocurrencies like Bitcoin and stablecoins, while non-U.S. countries, represented by China, are increasingly investing in gold as a means to detach from the dollar system [1][11] - The U.S. has allegedly depleted its usable gold reserves, leading to a reliance on digital currencies to sustain the dollar's value [1][5] - Non-U.S. countries are avoiding the "digital dollar trap" and are accumulating gold, which is viewed as a more stable asset [1][10] Group 2 - The dollar system has become a fragile structure since the U.S. decoupled the dollar from gold in 1971, leading to a cycle of dollar output and debt input that is now breaking down [2][3] - Central banks, including those of China, Saudi Arabia, and Japan, are reducing their holdings of U.S. Treasury bonds, indicating a shift in global financial dynamics [3][4] - The U.S. has a potential solution to this imbalance through the revaluation of gold, which could significantly alter its debt-to-GDP ratio [4][5] Group 3 - The U.S. holds 8,133.5 tons of gold, but it has not been properly audited for decades, leading to a discrepancy between its book value and market value [5][6] - The fear of revealing the true state of U.S. gold reserves prevents the government from revaluing gold, as it could expose potential shortages or mismanagement [6][7] - The U.S. is resorting to digital currencies as a temporary fix, despite the risks associated with losing control over monetary policy and inflation [8][9] Group 4 - Non-U.S. countries are stockpiling gold as a means of financial sovereignty, with China increasing its gold reserves for 17 consecutive months and other nations following suit [10][11] - Gold is seen as a reliable asset that does not depend on the U.S. financial system, making it a preferred choice for countries looking to secure their financial future [10][11] - The ongoing "currency cold war" suggests a fundamental shift in global financial power, with one system undermining itself while another fortifies its position [11]
