Mined in America Act Targets China Bitcoin Mining Hardware Supply
US senators Bill Cassidy and Cynthia Lummis introduced the “Mined in America Act” on Mar. 30 to reduce China’s dominance in US Bitcoin mining hardware supply. The bill cites a supply-chain risk: Cassidy’s office says 97% of mining hardware comes from China, while Hashrate Index estimates the US controls about 37%–38% of global hash rate.
Key proposal: a voluntary “Mined in America” certification led by the US Department of Commerce. Certified sites would phase out mining equipment linked to foreign adversaries. The act also supports domestic hardware manufacturing through NIST and the Manufacturing Extension Partnership, and it would codify Trump’s Strategic Bitcoin Reserve into law.
New enforcement detail in the latest coverage: Reuters says US authorities began seizing some Chinese-made mining equipment at ports under FCC/Customs grounds in late 2024, then released some in March 2025—backers argue this proves the dependency is operationally material.
Trader-relevant context: CoinShares data cited in the article puts “hash price” near $30–$35 per petahash per day, with around 15%–20% of the global fleet operating at a loss. That means customs holds, tariff escalation, or replacement-supply delays could quickly pressure margins.
Market takeaway: the Mined in America Act is a potential long-cycle supply-side catalyst for Bitcoin (BTC), but near-term impact depends on whether US/ally hardware capacity can scale fast enough. Separately, the SEC’s March 17 guidance on protocol mining signals continued regulatory formalization around crypto infrastructure.
Bullish
The Mined in America Act targets China-linked Bitcoin mining hardware and proposes a Commerce-led certification regime, which can gradually reduce geopolitical and logistics risk in BTC mining. The latest enforcement detail (port seizures and partial releases) reinforces that dependency can become a real operational constraint, especially when mining economics are already tight (15%–20% of the fleet reportedly at a loss). That combination can support a longer-cycle narrative of supply-side tightening and investment in domestic/ally mining capacity, which is generally favorable for BTC over time. Short-term outcomes are uncertain because scaling US/ally hash power and equipment availability may take time, so the immediate price reaction could be limited; however, the policy direction is constructive for BTC’s medium-to-long term risk premium. Separately, SEC protocol-mining guidance adds regulatory clarity, which tends to support infrastructure credibility rather than undermine it.
