American Bitcoin Corp Surpasses 7,000 BTC Mark
The American Bitcoin Corp has surpassed the 7,000 BTC mark in its corporate treasury, positioning itself as the 16th largest publicly traded company holding Bitcoin globally. The company, supported by Hut 8, announced this milestone on March 30, 2026, highlighting that it has nearly tripled its reserves since its Nasdaq debut in September 2025.
With a current Bitcoin price of approximately $67,500, the value of its holdings is estimated to be between $473 million and $475 million. The company operates around 89,000 miners, achieving a hashrate of about 28.1 EH/s after acquiring 11,298 new ASICs in early March 2026.
Key Takeaways: American Bitcoin Corp's significant growth in Bitcoin reserves reflects its strategic approach to holding mined and purchased Bitcoin, despite facing stock price challenges.
Bitcoin Hashrate Declines for the First Time in Six Years
In a significant shift, the Bitcoin hashrate has recorded its first decline in the first quarter of 2026, dropping approximately 4% from the beginning of the year. This marks the first decrease since 2020, breaking a long-standing growth trend. The decline is attributed to miners reallocating capital towards AI infrastructure as mining profitability diminishes.
As production costs near $90,000 per Bitcoin while market prices hover around $67,000, many miners are facing negative margins. This transition to AI infrastructure is expected to reduce the concentration of power among large US mining companies, potentially enhancing network decentralization.
Key Takeaways: The decline in Bitcoin hashrate signals a shift in the mining landscape, with miners pivoting towards more profitable AI ventures amidst challenging market conditions.
CoinShares Warns of Profitability Crisis in Bitcoin Mining
According to CoinShares' latest quarterly report, up to 20% of global mining capacities are at risk of economic failure due to declining revenues and high operational costs. This situation has forced some operators to shut down their hardware, leading to a significant drop in mining difficulty.
The hashprice, a critical indicator of miner profitability, fell to a new low of around $28 in February 2026, although it has since recovered slightly to about $33. Miners using older hardware or lacking access to cheap energy sources are particularly affected, with many needing electricity costs below $0.05 per kilowatt-hour to remain profitable.
Key Takeaways: The Bitcoin mining sector faces a profitability crisis, with many miners struggling to maintain operations amid rising costs and declining revenues.
US Senators Introduce the Mined in America Act
On March 30, 2026, Senators Bill Cassidy and Cynthia Lummis introduced the "Mined in America Act," aimed at relocating digital mining operations back to the United States. The legislation seeks to establish a national Bitcoin reserve and addresses supply chain risks associated with foreign mining hardware.
The act proposes a voluntary certification program for mining facilities and pools, ensuring they do not use equipment linked to foreign adversaries. This initiative is expected to strengthen the domestic mining industry and enhance national security.
Key Takeaways: The Mined in America Act represents a significant legislative effort to bolster domestic Bitcoin mining and reduce reliance on foreign hardware.
