U.S. Senators Bill Cassidy and Cynthia Lummis introduced the Mined in America Act on March 30, 2026, aiming to reduce American Bitcoin mining's reliance on Chinese-made hardware. The bill proposes a voluntary certification program to phase out foreign adversary-linked mining equipment, supports domestic manufacturing, and codifies the Strategic Bitcoin Reserve into law. The legislation addresses concerns that the U.S., which holds about 38% of global Bitcoin mining capacity, sources 97% of its mining hardware from China, creating a national security vulnerability. This follows 2024-2025 U.S. port seizures of Chinese mining gear, highlighting supply-chain risks in an industry now tied to federal policy. The bill frames Bitcoin mining as an industrial policy issue akin to semiconductors, seeking to bolster domestic hardware production while maintaining U.S. mining leadership. Its success hinges on whether American manufacturers can compete on cost and scale against established Chinese suppliers.

The U.S. Senate Banking Committee aims to mark up the Digital Asset Market Clarity Act in late April, with a deadline to pass it by May to avoid delays until after the 2026 midterms. The bill would restrict passive yield on stablecoins while allowing activity-based rewards, clarifying Bitcoin's role as a commodity asset. If passed, CLARITY is expected to strengthen Bitcoin's legal standing and market dominance, while stablecoins would shift toward payments utility with limited earnings potential. This regulatory clarity could drive institutional investment into Bitcoin, as seen in market reactions to earlier proposals.

A new whitepaper from Google Quantum AI reveals that nearly 6.7 million Bitcoin are held in quantum-vulnerable addresses, with some dating back to the earliest mining era and potentially belonging to Satoshi Nakamoto. These dormant coins, stored in Pay-to-Public-Key scripts, are at risk from future quantum computers that could derive private keys without transaction initiation. The research highlights that these addresses cannot be upgraded to post-quantum cryptography, posing a fixed and growing threat. Discussions are emerging on potential solutions, such as protocol-level destruction or regulated recovery, as the window to address this vulnerability narrows.

Interactive Brokers has expanded its crypto trading services to the European Economic Area through an integration with Zero Hash. Eligible individual investors in the region can now trade 11 cryptocurrencies, including BTC, ETH, SOL, and XRP, alongside traditional financial instruments via the company's platform suite. The launch is facilitated via Interactive Brokers Ireland Limited, providing a unified portfolio management experience. Outside the EEA, the company already offers crypto trading in the United States and the United Kingdom through its respective subsidiaries.

Google's Quantum AI team published a whitepaper indicating that breaking the elliptic curve cryptography protecting Bitcoin and Ethereum wallets could require fewer than 500,000 physical qubits, significantly reducing previous estimates. The research suggests quantum computers might achieve this by the end of the decade, compressing the timeline for potential threats. The paper highlights that about 6.9 million Bitcoin, including early wallets like Satoshi Nakamoto's, have exposed public keys, making them vulnerable. Reactions in the crypto community are split, with Ethereum praised for its post-quantum research efforts, while Bitcoin faces calls for urgent action to develop migration plans. Industry experts emphasize the need for protocols to upgrade to quantum-resistant algorithms, noting the challenge of coordinating such changes in decentralized systems. Google is collaborating with entities like Coinbase and the Ethereum Foundation to support a responsible transition, framing the research as a call to action for the ecosystem's long-term health.

Two US Republican senators have introduced the 'Mined in America Act' to boost domestic Bitcoin mining and manufacturing. The bill creates a voluntary certification requiring facilities to phase out equipment from foreign adversaries and support US-made hardware. It also aims to codify an executive order to establish a Strategic Bitcoin Reserve. The US leads in Bitcoin mining hashrate, but most mining hardware is manufactured by Chinese companies, highlighting the bill's focus on reducing dependency.

U.S. Senators Bill Cassidy and Cynthia Lummis introduced the Mined in America Act to support Bitcoin mining through federal certification and programs. The bill aims to reduce reliance on foreign adversaries like China and Russia by encouraging domestic mining equipment production and job creation. It also seeks to enshrine President Trump's proposed Strategic Bitcoin Reserve into law, aligning with broader efforts to bolster U.S. digital asset infrastructure.

The U.S. Department of Labor has proposed a rule that could expand investment options in 401(k) retirement plans to include alternative assets like Bitcoin. The proposal aims to reduce regulatory uncertainty for fiduciaries by emphasizing a process-based approach to evaluating investments. This move reverses prior guidance that cautioned against cryptocurrency in retirement plans, instead establishing safe harbor frameworks for thorough due diligence. The rule could allow for increased exposure to digital assets, potentially enhancing long-term returns and inflation hedging for younger savers.

Square has begun rolling out Bitcoin payments at its point-of-sale terminals for eligible US merchants. The feature automatically converts Bitcoin to US dollars at checkout with no processing fees through 2026. The rollout, which aims to make Bitcoin usable as everyday money, is part of a phased implementation expected to reach all Square merchants by November 10. Eligible sellers must meet verification requirements and cannot be based in New York.

U.S. Senators Bill Cassidy and Cynthia Lummis introduced the 'Mined in America Act' to promote domestic Bitcoin mining and establish a Strategic Bitcoin Reserve. The bill creates a certification program for U.S.-based mining operations and aims to reduce reliance on foreign hardware, particularly from China. It also codifies a Strategic Bitcoin Reserve within the Treasury Department, funded through seized digital assets and direct purchases from certified miners. The legislation positions Bitcoin mining as a tool for grid management and energy development, integrating it into existing federal programs.
