U.S. Senators Introduce “Mined in America” Bill to Boost Bitcoin Mining

• Bill links domestic Bitcoin mining expansion to formalizing a Strategic Bitcoin Reserve framework.
• Certification program targets supply chains, requiring shift from foreign hardware to U.S. production.
• Proposal aims to reduce reliance on China and strengthen U.S. crypto infrastructure leadership.

U.S. Senators Cynthia Lummis and Bill Cassidy introduced the “Mined in America Act” on Monday to strengthen domestic Bitcoin mining and formalize a Strategic Bitcoin Reserve. The proposal follows President Donald Trump’s March executive order and aims to expand mining infrastructure, reduce foreign reliance, and embed digital assets deeper into the U.S. financial system.

Mining Push Tied to Reserve Framework

The bill directly builds on Trump’s earlier executive order establishing a Strategic Bitcoin Reserve. That reserve uses Bitcoin seized through criminal and civil forfeitures held by the Treasury.

Moreover, the legislation seeks to turn that executive action into permanent law. Lawmakers also positioned mining as a key supply source supporting the reserve’s long-term structure.

Lummis stated the initiative aligns with Trump’s pledge to make the U.S. a global crypto hub. Meanwhile, Cassidy emphasized mining’s growing role within the national economy.

Certification Program and Supply Chain Shift

The proposal introduces a voluntary certification program for mining facilities and pools. The Commerce Department would oversee this system, setting compliance and operational benchmarks.

Notably, certified operators must begin phasing out hardware tied to foreign adversaries. This requirement targets supply chain risks tied to overseas manufacturing dominance.

In addition, the bill directs federal agencies to support domestic mining hardware production. Programs under the National Institute of Standards and Technology would assist U.S. manufacturers in building secure equipment.

Industry Concerns and Political Backdrop

According to the Satoshi Action Fund, the U.S. controls 38% of global Bitcoin hash rate. However, 87% of mining hardware still comes from China.

Dennis Porter described this imbalance as a structural risk to U.S. leadership. As a result, the bill aims to localize infrastructure and reduce external dependencies.

At the same time, the proposal enters a complex political environment. Other crypto legislation, including the CLARITY Act, faces delays amid regulatory disagreements.

Separately, Senator Elizabeth Warren has raised concerns about security risks linked to Chinese mining firm Bitmain. Federal authorities are reviewing whether such equipment could pose surveillance threats.
