Republican Senators Introduce 'Mined in America Act' to Strengthen Domestic Bitcoin Mining Infrastructure and Formalize Reserve
Despite the United States controlling 38% of the Bitcoin hashrate globally, approximately 97% of mining hardware originates from two manufacturers based in China, as noted by a Bitcoin policy expert.
A pair of Republican US senators have put forth legislation titled the "Mined in America Act" in a bid to restore Bitcoin mining equipment production to American soil while also formally establishing US President Donald Trump's executive directive creating a Strategic Bitcoin Reserve.
Presented by US Senators Cynthia Lummis and Bill Cassidy this Monday, the proposed legislation aims to establish an optional "Mined in America" certification program applicable to cryptocurrency mining operations and mining pools. Operations receiving certification would need to gradually eliminate mining machinery produced by entities connected to "foreign adversaries," while promoting the domestic production of mining equipment.
"Digital asset mining is a big part of our economy. We should be doing it here in America," Cassidy stated in a Monday announcement.
Following China's prohibition on Bitcoin mining activities in 2021, the United States emerged as the world's dominant Bitcoin mining nation measured by hashrate. Currently, the US accounts for approximately 38% of the total Bitcoin network hashrate, which represents more than twice the share held by Russia, the country in second position.
"The Mined in America Act breaks that dependency by building a virtuous cycle of domestic manufacturing, certified mining operations, grid-strengthening energy infrastructure and a pipeline to the Strategic Bitcoin Reserve," Porter said.
The Bitcoin mining sector in the United States experienced disruption from an extended incident beginning in late 2024 during which the US Customs and Border Protection halted shipments involving thousands of Bitmain ASIC mining machines at American ports.
Luxor Technology, a Bitcoin mining enterprise, was one of the companies affected by the situation. The company's chief operating officer, Ethan Vera, informed Cointelegraph in March 2025 that the mining equipment had been confiscated due to an erroneous assumption that they constituted illegally imported radio frequency devices.
