Two US lawmakers have introduced legislation to reshape the country’s role in digital asset infrastructure, focusing on domestic Bitcoin mining and the creation of a national reserve.
The proposed Mined in America Act, introduced by Bill Cassidy and Cynthia Lummisaims to expand US-based cryptocurrency mining while reducing dependence on foreign supply chains. The bill also codifies a strategic Bitcoin reserve, in line with previous executive actions.
The bill focuses on domestic mining and supply chain control
At its core, the legislation introduces a voluntary certification program for mining operations, allowing facilities to qualify as “Mined in America” if they meet certain criteria.
An important provision requires participating entities to do so phase out mining hardware linked to foreign adversaries.
This is in light of industry estimates that while the The US is responsible for approximately 38% of Bitcoin’s global hash ratethe vast majority of mining equipment is manufactured abroad.
The bill also directs federal agencies to support the development of U.S.-based mining hardware. Also to integrate mining projects into existing energy and rural infrastructure programs, rather than creating new spending initiatives.
Strategic Bitcoin Reserve Moves Toward Formalization
In addition to mining, the legislation would formally establish a strategic Bitcoin reserve within the U.S. Treasury Department.
While previous executive actions had outlined the concept, the bill aims to enshrine it in law. This signals a broader shift toward treating Bitcoin as part of the national financial strategy.
Proponents of the proposal argue that aligning mining, manufacturing and reserve management could strengthen U.S. leadership in digital assets while reducing exposure to foreign-controlled infrastructure.
Mining activity remains resilient despite price volatility
Market data shows that mining continues to grow even during periods of price weakness.
Recent data from Glassnode shows that Bitcoin’s hash rate is near all-time highs, hovering between 0.9T and 1.2T, even as prices have fallen from late 2025 highs.
The difference signals continued investment in mining infrastructure, strengthening its role as a fundamental layer of the network rather than as a purely price-driven activity.
The trend underlines why policymakers are increasingly focused on securing mining capacity and supply chains as part of a broader digital asset strategy.
Final summary
- The proposed bill aims to localize Bitcoin mining, reduce dependence on foreign hardware, and formalize a US strategic Bitcoin reserve.
- Continued mining activity despite price volatility highlights why governments are beginning to view Bitcoin infrastructure as strategically important.
