U.S. Senator Cynthia Lummis has introduced two significant pieces of legislation aimed at integrating Bitcoin and other cryptocurrencies more fully into the American financial system. The first bill, unveiled in early July 2025, seeks to eliminate capital gains taxes on Bitcoin payments under $300, establishing a de minimis exemption to protect small personal transactions from taxation. This legislation also aims to end double taxation on cryptocurrency mining and staking activities and to align digital asset taxation with traditional financial practices, including fair treatment for lending and donations involving crypto. Later in July 2025, Senator Lummis introduced the "Digital Asset Mortgage Reserves Act," which requires government-sponsored enterprises Fannie Mae and Freddie Mac to recognize Bitcoin and other digital assets as valid collateral for mortgage eligibility assessments. This bill would allow Americans to use their cryptocurrency holdings when applying for home loans without the need for fiat currency conversion, marking a notable step toward mainstream acceptance of digital assets in real estate financing.
