US Targets Chinese Tech in Bitcoin Mining Crackdown
U.S. lawmakers are escalating scrutiny of the Bitcoin mining supply chain after analysis showed the country accounts for roughly 38% of global mining capacity while most specialized mining rigs remain manufactured by Chinese firms. In March, Senators Bill Cassidy and Cynthia Lummis introduced the Mined in America Act to push procurement and production toward domestic or allied suppliers, aiming to reduce dependence on Chinese-made equipment.
The proposal raises near-term risks for miners, hardware makers and BTC markets by spotlighting possible procurement restrictions, tariffs or export controls that could increase costs and slow equipment availability. If adopted, the law could accelerate efforts to build U.S. chip and rig production but also create short-term disruption to hash rate and operational planning. Traders and operators will be watching regulatory timelines and manufacturer responses closely, as outcomes could materially alter mining geography and capital expenditure for Bitcoin miners.
