US Senators Propose Reserve-Backed Bitcoin Mining Plan Sparking Nationalization Debate

Key Points

• Bill proposes federal certification for domestic Bitcoin miners and Treasury purchasing mechanism.
• Aims to reduce foreign hardware reliance and formalize a Strategic Bitcoin Reserve.

Senators Bill Cassidy and Cynthia Lummis introduced the Mined in America Act on March 30, 2026, proposing a voluntary federal certification program for domestic Bitcoin mining facilities.

The bill would also codify a Strategic Bitcoin Reserve and allow certified miners to sell newly mined BTC to the U.S. Treasury in exchange for a capital gains tax exemption.

The proposal includes no new spending authorizations and assigns the Department of Commerce as the certifying authority.

It directs the National Institute of Standards and Technology and the Manufacturing Extension Partnership to support domestic mining hardware development, citing concerns over foreign-manufactured equipment.

The legislation is expected to be reviewed by the Senate Commerce, Science, and Transportation Committee and follows earlier efforts to establish Treasury-managed custody of federal Bitcoin holdings.

Certification Requirements and Treasury Purchasing Structure

Mining firms seeking “Mined in America” certification must demonstrate that they do not operate hardware produced by manufacturers based in countries designated as foreign adversaries under U.S. trade law.

Operators must phase out restricted equipment by the end of the decade, affecting widely used suppliers such as Bitmain Technologies and MicroBT.

Certified miners would gain access to existing Department of Energy and U.S. Department of Agriculture programs, including grid stabilization arrangements and methane capture initiatives, without creating new federal expenditures.

The bill links certification to Treasury acquisitions by allowing designated miners to sell newly mined Bitcoin to the government at market prices while receiving a capital gains tax exemption on those transactions.

Additional reserve purchases could be funded through proceeds generated from staking rewards and airdrops tied to federally held digital assets seized in prior enforcement actions.

Hash Rate Concentration and Market Impact

The United States accounts for roughly 38% of global Bitcoin hash rate, largely powered by imported hardware.

U.S. Customs inspections in late 2024 identified remote-access vulnerabilities in certain imported mining rigs, contributing to policy discussions around supply chain security.

If enacted, the certification and tax incentive framework could shift demand toward domestically produced ASIC equipment, potentially reshaping procurement patterns within the mining industry.

Transitioning to a domestic hardware base may increase short-term costs for some operators, particularly mid-sized firms with limited capital flexibility.

The Treasury procurement channel would introduce a recurring government buyer of newly mined Bitcoin, potentially reducing the volume entering open markets if adoption among certified miners proves significant.
