Two US senators have proposed a bill that seeks to strengthen the crypto mining industry and solidify President Donald Trump’s idea of creating a strategic Bitcoin reserve.

Put forward by US Republican Senators Bill Cassidy and Cynthia Lummis, the proposed Mined in America Act would position cryptocurrency mining as part of the US’ “critical digital infrastructure” push, with an emphasis on domestic manufacturing and supply chain security.

Under the proposal, the Department of Commerce would establish a voluntary 'Mined in America' certification program for cryptocurrency mining facilities and mining pools.

To qualify, certified operators would be required to transition away from mining hardware made by companies linked to foreign adversaries.

“America controls 38 percent of the world’s Bitcoin hash rate, but 97 percent of the hardware powering it comes from China. That is not leadership, that is a liability,” stated the senators' announcement of the bill.

The bill also seeks to support a domestic mining equipment base by directing the National Institute of Standards and Technology and the Manufacturing Extension Partnership to help US manufacturers develop secure, energy-efficient crypto mining systems.

Rather than create new federal spending programs, the bill would steer certified projects toward existing energy and rural development schemes, according to the senators’ office.

The legislation would also codify President Donald Trump’s March 6, 2025, executive order establishing a Strategic Bitcoin Reserve within the Department of the Treasury.

The White House said the reserve would be built up using Bitcoin already held by Treasury through criminal or civil forfeiture, and that deposited Bitcoin would not be sold, while Treasury and Commerce were authorized to explore budget-neutral ways to acquire more.

Backers of the bill are presenting it in the frame of national competitiveness and supply-chain security. Cassidy said digital asset mining should be done “here in America,” while Lummis framed the bill as part of a broader effort to make the US the “digital asset capital of the world.”

Two of President Trump's children are involved with American Bitcoin, a publicly-listed miner that has seen its value fall from $5bn in September to under $1bn today.
