The U.S. runs more Bitcoin mining rigs than any other country on the planet.

But here's the thing - nearly all of those machines were built somewhere else. That's the gap two senators want to close.

Washington Wants American-Made Mining Machines

Senators Bill Cassidy and Cynthia Lummis introduced a bill on March 30 called the "Mined in America Act." It's their bid to bring the hardware side of Bitcoin mining back onshore.

The bill sets up a program where mining facilities can earn a federal "Mined in America" label - but only if they ditch equipment from countries considered foreign adversaries.

The Commerce Department would run the program. The bill doesn't ask for new funding - instead, it leans on energy and rural development programs that already exist to help operators make the switch.

Federal tech agencies like NIST and the Manufacturing Extension Partnership would also pitch in, working to grow a domestic supply of mining gear that doesn't depend on overseas factories.

Why it matters for investors: American operations account for about 38% of all Bitcoin computing power globally. But the hardware powering those rigs comes almost entirely from abroad. That's a weak spot lawmakers want to fix before it turns into a real problem.

The Bitcoin Reserve Gets a Legal Upgrade

The other half of the bill locks in the Strategic Bitcoin Reserve as actual law.

Trump created the reserve through an executive order in March 2025. The government stocked it with coins it had already seized through criminal cases and legal penalties.

Those coins are supposed to stay put - not sold off. Treasury and Commerce officials were also asked to find budget-friendly ways to grow the stash without adding to the national tab.

But executive orders can be undone with a signature. Writing the reserve into law would take that option off the table.

Lummis has been building toward this for over a year. She pushed the BITCOIN Act of 2025 last March to create a broader legal framework for the reserve. This latest bill adds an industrial layer on top.

What to Watch

The bill still needs enough votes in Congress - and that's the part nobody can predict.

But investors should pay attention to the signal, not just the bill. Lawmakers are starting to treat Bitcoin mining the way they treat chip factories or power grids - as national infrastructure worth defending.

The data backs it up. Glassnode shows Bitcoin's total network computing power sitting in a range of 0.9 trillion to 1.2 trillion - holding strong even after prices pulled back from their late-2025 peaks.

Miners keep spending money and plugging in machines no matter what the price chart looks like. Washington finally seems to agree that matters.
