From Decentralization to Control: How the U.S. Bitcoin Reserve Reshapes Mining Power

Bitcoin was founded on the principle of decentralization, designed to function beyond the control of any single government, corporation, or entity. However, as the United States consolidates its Bitcoin strategy, concerns over the centralization of mining power are growing. The rise of the U.S. Strategic Bitcoin Reserve, coupled with increasing U.S. dominance in mining operations, is shifting the global balance of Bitcoin’s network security. While greater institutional involvement signals mainstream adoption, it also raises concerns over censorship, regulatory overreach, and Bitcoin’s long-term ability to resist state control.

The U.S. Leads in Global Bitcoin Mining

Since China’s 2021 crackdown on Bitcoin mining, the U.S. has emerged as the dominant force in global hashrate distribution. As of 2025, more than 38% of Bitcoin’s total hashrate is controlled by U.S.-based mining pools, making it the world’s largest mining hub. This dominance is driven by large-scale mining firms such as Foundry USA, Marathon Digital, and Riot Platforms, which operate massive facilities across states like Texas, Kentucky, and North Dakota.

The presence of regulated mining companies has attracted legitimacy and investment to the industry, but it also introduces new risks. Unlike decentralized, geographically distributed mining, U.S.-based operations are subject to federal regulations, environmental policies, and compliance requirements that could lead to government influence over Bitcoin’s network.

The Link Between the U.S. Bitcoin Reserve and Mining Power

Beyond mining dominance, the U.S. is also gaining financial control over Bitcoin. Major institutions like BlackRock and Fidelity hold significant Bitcoin reserves through ETFs, while companies like MicroStrategy own substantial amounts of the asset. This financial influence complements the country’s expanding control over mining operations, positioning the U.S. as a central force in Bitcoin’s future.

From Financial Inclusion to Hashrate Control

A shift in the Bitcoin mining narrative is emerging among U.S. mining executives and policymakers. Marathon CEO Fred Thiel recently emphasized that U.S. mining companies, both domestic and international, have a mandate to secure enough hashrate for America and its allies. He highlighted how Bitcoin mining is being integrated into the U.S. energy infrastructure: “Bitcoin is the ultimate dispatchable load. Power generators want base load consumption to maintain consistent production. Bitcoin miners can shut down their operations in minutes and ramp them back up, responding to signals from the power grid.”

Thiel pointed out that renewable energy infrastructure, particularly in places like West Texas, has created an energy surplus, occasionally leading to negative energy pricing. To capitalize on this, Marathon acquired a wind farm in Texas, ensuring that excess energy is utilized efficiently.

More notably, Thiel framed Bitcoin mining as a geopolitical asset: “If U.S. Bitcoin miners expand internationally, that hashrate still belongs to the U.S. and its allies. The executive branch is focused on ensuring the U.S. acquires sufficient global hashrate to project power. While American companies go abroad, they are effectively bringing that hashrate home. We are not only exporting dollars through digital currencies and stablecoins but also projecting power through Bitcoin mining.”

This statement underscores a shift in Bitcoin’s role—from a decentralized, global network to a strategic national asset akin to the U.S. dollar. The U.S. is not only strengthening domestic Bitcoin mining but also encouraging its firms to expand globally while keeping operations under American oversight.
