U.S. Senators Introduce "Mined in America" Bill on Bitcoin Mining and Reserve

U.S. Senators Bill Cassidy and Cynthia Lummis introduced the "Mined in America" Act to shift Bitcoin mining supply chains toward U.S.-made hardware and codify a Strategic Bitcoin Reserve. According to the new report, about 97% of Bitcoin mining machines currently come from China-based companies, while the U.S. accounts for roughly 38% of global Bitcoin hashrate. The bill would create a "Mined in America" certification for data centers that do not use equipment made by foreign adversaries, pushing certified operators to replace hardware from major Chinese suppliers such as Bitmain and MicroBT with domestic alternatives. Federal agencies would support the transition, with the National Institute of Standards and Technology tasked with helping U.S. manufacturers develop more efficient chips and the Manufacturing Extension Partnership aimed at assisting small and medium-sized American factories. The legislation also seeks to put a Strategic Bitcoin Reserve into law and indicates that Bitcoin for that reserve should ideally come from certified "Mined in America" facilities.
