The U.S. Republican Party has introduced the "American Mining Act" to promote the expansion of mining and consolidate Bitcoin reserves.

U.S. Senators Cynthia Lummis and Bill Cassidy introduced the "Mined in America Act," aimed at promoting the development of the cryptocurrency mining industry and enshrining President Trump's executive order establishing a strategic Bitcoin reserve in law. The bill plans to strengthen the role of cryptocurrency mining in the U.S. economy while solidifying previous policy arrangements regarding the strategic Bitcoin reserve through legislation. This reserve primarily consists of Bitcoin seized by the U.S. Treasury Department through law enforcement. The bill also requires the U.S. Department of Commerce to establish a voluntary certification system to regulate mining pools and farms. Furthermore, certified mining farms must gradually reduce their reliance on mining equipment produced by companies associated with "foreign adversaries." The proponents stated that this bill is a key step in promoting the U.S. as a global digital asset center and aims to enhance the nation's strategic position in the cryptocurrency industry chain.
