Bill creates Treasury channel to buy US-mined Bitcoin

Cassidy and Lummis introduced the Mined in America Act on March 30, 2026. The bill sets a voluntary certification for U.S. Bitcoin miners, codifies a Strategic Bitcoin Reserve, and opens a Treasury channel to buy newly mined BTC with a capital gains tax exemption for certified sellers. Source.

The Department of Commerce would run certification. NIST and the Manufacturing Extension Partnership would support domestic mining hardware development. Coinspeaker.

Certified miners must phase out rigs from “foreign adversary” manufacturers by decade’s end. Operators must show no equipment from entities in countries designated under U.S. trade law, such as China and others named in the bill summary. Coinspeaker.

Hardware makers Bitmain and MicroBT dominate current fleets. The phase‑out sets a deadline for replacing their rigs in certified operations. Bitmain.

Certified miners gain access to existing DOE and USDA programs. This includes grid stabilization contracts, renewable load absorption, and methane capture deployments, without new appropriations. Coinspeaker.

The bill links certification to Treasury procurement. Certified miners may sell newly mined BTC to the Treasury at market rates and receive a capital gains tax exemption on those sales. Coinspeaker.

The United States controls about 38% of global network hash rate. Much of this runs on imported hardware. Blockchain.com hash rate.

The measure now awaits committee referral, likely to Senate Commerce, Science, and Transportation. Coinspeaker.

Key mechanics for investors and miners:
- Voluntary U.S. miner certification under Commerce; NIST and MEP back domestic ASIC efforts source.
- Full phase‑out of “foreign adversary” hardware by end of decade for certified status source.
- Treasury purchase channel for newly mined BTC with capital gains exemption on certified sales source.
- Access to existing DOE/USDA energy and methane programs without new funding lines source.
