Republican senators Bill Cassidy and Cynthia Lummis have introduced a new bill aimed at strengthening domestic crypto infrastructure by bringing Bitcoin mining manufacturing back to the United States while also supporting the creation of a Strategic Bitcoin Reserve.
Summary
The “Mined in America Act” aims to boost U.S.-based Bitcoin mining hardware production and establish a Strategic Bitcoin Reserve.
Certified mining operations would need to phase out foreign-sourced equipment and adopt domestically produced alternatives.
Rising tensions with China and concerns over companies like Bitmain have added pressure on the U.S. mining sector.
The proposed “Mined in America Act” introduces a voluntary certification system for crypto mining facilities and mining pools operating in the U.S. Under this framework, certified entities would be required to gradually replace equipment sourced from “foreign adversaries” with hardware manufactured domestically.
The legislation also calls on the National Institute of Standards and Technology and the Manufacturing Extension Partnership to assist American companies in developing more secure and energy-efficient mining technology.
In addition, the bill seeks to formalize efforts toward establishing a Strategic Bitcoin Reserve, signaling growing interest among policymakers in integrating digital assets into national economic strategy. Senator Cassidy emphasized the importance of domestic mining, stating that the industry should be developed within the U.S. economy.
U.S.-China tensions weigh on mining
The push for domestic production comes amid ongoing geopolitical tensions affecting the crypto mining sector. While the U.S. currently leads globally in Bitcoin hashrate—accounting for roughly 38% of the network—it still relies heavily on foreign-made mining equipment.
China continues to dominate the mining hardware supply chain, with major manufacturers like Bitmain and MicroBT controlling a significant share of global production.
Recent developments have further highlighted these dependencies. In March, U.S. mining firms experienced shipment delays after authorities halted imports of mining equipment at ports due to concerns over radio frequency emissions. Meanwhile, Elizabeth Warren raised national security questions related to Bitmain’s hardware, seeking clarification from the Commerce Department.
Against this backdrop, the “Mined in America Act” represents a broader effort to reduce reliance on foreign suppliers, strengthen supply chain resilience, and position the U.S. as a more self-sufficient player in the global Bitcoin mining ecosystem.
