A U.S. senator proposes the “American Mining Act”: elevate the “Strategic Bitcoin Reserve” into law, and break free from hardware dependence on China

U.S. Republican Senators Bill Cassidy and Cynthia Lummis officially introduced the Mined in America Act on March 30. The bill aims to bring critical digital infrastructure back to the United States, establish a secure cryptocurrency mining supply chain, and formally enshrine the “National Strategic Bitcoin Reserve” proposed by President Donald Trump into law.
(Background: Big news! The U.S. SEC will classify Bitcoin mining within securities laws, and has charged the mining company VBit with fraud totaling $95.6 million.)
(Additional context: Bitcoin mining in the U.S. has been impacted by severe cold weather! Miners are complying with power restrictions and shutting down; the hash rate of the Foundry USA mining pool has dropped by 60%.)

• Establish a Bitcoin strategic reserve and promote domestic mining
• The bill’s five core points: Reject foreign adversarial forces
• Breaking the dependency where 97% of hardware comes from China

The United States is once again taking a crucial step in its quest for global dominance in digital assets. On March 30, Louisiana Senator Bill Cassidy and Wyoming Senator and well-known “Bitcoin advocate” Cynthia Lummis jointly introduced the Mined in America Act, aiming to comprehensively strengthen the country’s cryptocurrency mining infrastructure.

Establish a Bitcoin strategic reserve and promote domestic mining

One of the bill’s main objectives is to codify into federal law the executive order previously signed by President Donald Trump to establish a “Strategic Bitcoin Reserve,” and to place this reserve under the U.S. Department of the Treasury to ensure its long-term stability.

“Digital asset mining is an important part of our economy. We should conduct this work within the United States,” Senator Cassidy stated. “This bill will ensure supply chain security, support American manufacturing, and bolster the development of the entire industry.”

Senator Lummis also supports the bill, emphasizing: “President Trump committed to making the U.S. the global capital of digital assets—we will not back down. The Mined in America Act brings this industry back home through forward-looking measures to safeguard our financial future.”

The bill’s five core points: Reject foreign adversarial forces

According to official documents, the Mined in America Act proposes five specific policies and initiatives:

2. Create a voluntary “Mined in America” certification: Directs the Department of Commerce to establish a voluntary certification program for cryptocurrency mining facilities and pools.
3. Eliminate hardware associated with foreign adversarial forces: Certified facilities must gradually phase out mining equipment produced by “companies linked to foreign adversarial forces.”
4. Integrate existing federal resources: Incorporate certified projects into current federal energy and rural development programs to support transition efforts without creating new government expenditures.
5. Support domestic mining hardware manufacturing: Instructs the National Institute of Standards and Technology (NIST) and the Manufacturing Extension Partnership (MEP) to assist U.S. manufacturers in developing secure, energy-efficient cryptocurrency mining equipment.
6. Legislate the establishment of a strategic Bitcoin reserve: Officially create a national-level strategic Bitcoin reserve within the U.S. Department of the Treasury.

Breaking the dependency where 97% of hardware comes from China

The bill has received strong backing from the well-known Bitcoin advocacy organization Satoshi Action Fund. Its CEO and co-founder, Dennis Porter, highlighted the current national security and industry concerns.

Porter sharply pointed out, “The U.S. controls 38% of the global Bitcoin hash rate, but up to 97% of the hardware driving this hash rate is from China. This is not leadership; it’s a liability.” The Mined in America Act aims to break this dependency by establishing a virtuous cycle involving domestic manufacturing, certified mining operations, strengthening the power grid, and ultimately creating a strategic Bitcoin reserve. Porter directly stated:

“If we truly want to lead in Bitcoin, we absolutely cannot let our adversaries hold the keys to our supply chain.”
