In 2025, the United States will achieve a significant breakthrough in cryptocurrency legislation. In March, the Trump administration signed the 'Bitcoin Strategic Reserve Act,' incorporating 200,000 BTC (6% of the circulation) seized by the judiciary into the national reserve and permanently banning its sale, thereby strengthening Bitcoin's 'digital gold' attributes through a 'zero-cost accumulation' mechanism. Meanwhile, the 'Stablecoin Accountability Act' is being expedited, requiring 100% dollar reserves and real-time audits, promoting the integration of banks and the crypto market. Additionally, Congress has repealed IRS tax reporting rules for DeFi, protecting privacy and innovation. There is high legislative enthusiasm among states, with 24 states proposing cryptocurrency reserve bills, although some have been shelved due to risk concerns. Senator Cynthia Lummis has also proposed establishing a national strategic reserve of 1 million BTC to solidify the United States' financial leadership. These initiatives signify that the U.S. is systematically restructuring its cryptocurrency regulatory framework to compete for global digital finance dominance.
