A groundbreaking research from the Cambridge Centre for Different Finance (CCAF) claims that the US now dominates Bitcoin mining, controlling as a lot as 75.4% of the worldwide hashing energy. “The U.S. has solidified its place as the most important world mining hub (75.4% of reported exercise),” the CCAF studies, primarily based on a survey of 49 mining companies representing practically half the Bitcoin community’s hashrate.
This focus, equating to roughly 600 exahashes per second (EH/s) of the worldwide 796 EH/s, raises a urgent concern: Is Bitcoin mining changing into dangerously centralized within the U.S., and what dangers does this pose for the rising asset’s future?
Howard Lutnick, U.S. Secretary of Commerce and former CEO of Cantor Fitzgerald, not too long ago shared insights into the Trump administration’s imaginative and prescient to place the U.S. as a Bitcoin superpower. “It’s like gold. To me. It’s a commodity,” Lutnick stated in an interview with Frank Corva of Bitcoin Journal, highlighting Bitcoin’s fastened provide of 21 million cash. He outlined plans to “turbocharge” U.S. mining by way of the Commerce Division’s Funding Accelerator, which streamlines permits for miners to construct off-grid energy vegetation. “You’ll be able to construct your personal energy plant subsequent to [your data center]. I imply, take into consideration that for a second,” he stated.
This pro-business stance has fueled America’s mining increase, however the CCAF’s findings counsel a draw back: centralization. For years, Bitcoiners apprehensive about China’s dominance, which peaked at 65–75% of world hashrate earlier than its June 2021 mining ban. “In 2019, China dominated world Bitcoin mining, accounting for 65–75% of the full Bitcoin community,” a 2025 Nature Communications research notes. When China banned mining, hashrate dispersed globally, with many operations relocating to the U.S., drawn to states with considerable vitality and favorable insurance policies. This shift triggered a 50% market correction however paved the way in which for a 130% rise towards the tip of the 12 months, demonstrating the market’s resilience.
Whereas China’s historic hashrate focus by no means led to community abuse, it was a continuing concern. Now, with the U.S. holding 75% of hashrate, related dangers emerge. The Trump administration is Bitcoin-friendly, however a future administration may flip hostile, leveraging centralized hashrate to manage the community. In contrast to China’s ban, a future U.S. authorities may attempt to regulate or manipulate mining, utilizing government powers like sanctions to censor transactions — a risk amplified by mining’s focus.
The U.S.’s federal construction gives a possible safeguard. The division of powers between states and the federal authorities may allow resistance to federal overreach. In states with vital mining exercise, officers and the general public may argue that manipulating the business harms Bitcoin’s worth, impacting traders. Such resistance may protect the community’s integrity.
The weakening of the U.S. financial sanctions regime may play to our benefit. Following the 2022 seizure of Russian treasuries, nations misaligned with U.S. coverage have diminished U.S. bond purchases, undermining the fiat rails abused in sanctions. The Trump administration is shifting towards tariffs to manage items fairly than cash flows, probably decreasing the specter of financial censorship. This pivot buys Bitcoin time, as centralized hashrate could also be a tender goal for federal intervention.
Nonetheless, American Bitcoiners should keep proactive. Deepening Bitcoin adoption to embed it broadly within the economic system and all through the world may deter censorship, as assaults on the community would hurt private wealth, spurring backlash. Historical past additionally reveals miners adapt when displaced — China’s ban proved that — however governments be taught. A future U.S. administration won’t ban mining however search to manage it, exploiting centralization.
The Bitcoin business faces a important juncture. With as a lot as 75.4% of hashrate within the U.S., even low estimates of fifty% current a centralization threat that looms massive. Ought to we diversify globally or lean into America’s mining dominance? As Lutnick’s imaginative and prescient unfolds, Bitcoiners should guarantee this sovereign cash stays resilient, no matter who holds energy.
