Bitcoin's network hashrate fell nearly 6% after a US-Israel joint operation in Iran on February 28, with Iran estimated to represent 6–8% of global mining capacity. In March 2026, several major miners accelerated a pivot toward AI data centers, including MARA Holdings' sale of 15,133 BTC for about $1.1 billion and Core Scientific's $1 billion debt financing from JPMorgan and Morgan Stanley. Other firms moved the opposite way, with American Bitcoin disclosing holdings of 7,000 BTC after its September 2025 Nasdaq debut.

On Monday, Michael Saylor shared an AI-made ad promoting Strategy Inc.’s STRC preferred stock, which later passed 1.67 million views on X. The spot pitches early retirement via monthly dividends from STRC, described as an ~11.5% annualized payout, while also warning it is not FDIC-insured and is exposed to bitcoin volatility. Viewers largely mocked the video’s production and optics, with some traders calling it a late-cycle “top signal,” while a smaller group defended it as attention-grabbing marketing.

Bitcoin (BTC) bounced from the $65,000 area and reclaimed $67,000 and $67,500, with price trading above the 100-hour simple moving average. It is now consolidating below $68,500, where resistance also sits around $68,800, and a rejection could put $67,200 and $67,000 back in focus. Upside levels cited include $69,250, $69,500, and $70,000 if $68,800 is cleared.

On March 30, 2026, the Senate Banking Committee said Sen. Elizabeth Warren sent a March 26 letter to Commerce Secretary Howard Lutnick seeking clarity on oversight of Bitmain and its reported ties to Eric Trump's mining firm, American Bitcoin. The letter cites concerns about foreign influence, potential remote-access risks involving mining hardware used in the U.S., and a financing arrangement Warren described as unusually generous. Warren asked the department to provide records and answers by April 9, 2026.

Strategy said in an SEC Form 8-K dated March 30, 2026 that it made no bitcoin purchases and sold no shares during March 23, 2026 to March 29, 2026. The filing also lists holdings of about 762,099 BTC acquired for $57.69 billion at an average of approximately $75,694 per bitcoin, inclusive of fees and expenses. Separately, Michael Saylor shared X posts highlighting STRC’s reported 11.5% dividend yield and about 2% 30-day volatility versus bitcoin at 50%.

US Senators Bill Cassidy and Cynthia Lummis introduced the "Mined in America Act" on Monday to encourage domestic Bitcoin mining hardware manufacturing and formalize President Donald Trump's Strategic Bitcoin Reserve order. The proposal would create an optional certification for mining facilities and pools, requiring certified participants to phase out equipment made by firms linked to "foreign adversaries." The US hosts about 38% of the Bitcoin network hashrate, while 97% of mining hardware is produced by Bitmain and MicroBT.

American Bitcoin Corp. (Nasdaq: ABTC) said its corporate treasury exceeded 7,000 BTC on Sunday, after disclosing the milestone on Monday. With bitcoin near $67,500, the stash is valued around $473 million to $475 million, and the miner reported it has scaled to roughly 89,000 machines producing about 28.1 EH/s after buying 11,298 ASICs in early March 2026.

Republican Sens. Cynthia Lummis and Bill Cassidy unveiled the "Mined in America Act" on Monday to expand digital asset mining's role in the U.S. economy. The proposal would also write into law President Donald Trump's executive order establishing a strategic bitcoin reserve. It further directs the Commerce Department to create a voluntary certification program for mining pools and facilities, including a requirement for certified sites to move away from equipment made by firms tied to foreign adversaries.
