A groundbreaking examine from the Cambridge Centre for Various Finance (CCAF) claims that america 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 international mining hub (75.4% of reported exercise),” the CCAF stories, 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, just lately 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 mounted provide of 21 million cash. He outlined plans to “turbocharge” U.S. mining by means of the Commerce Division’s Funding Accelerator, which streamlines permits for miners to construct off-grid energy crops. “You’ll be able to construct your individual 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 growth, however the CCAF’s findings recommend a draw back: centralization. For years, Bitcoiners frightened about China’s dominance, which peaked at 65–75% of worldwide hashrate earlier than its June 2021 mining ban. “In 2019, China dominated international Bitcoin mining, accounting for 65–75% of the full Bitcoin community,” a 2025 Nature Communications examine 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 precipitated a 50% market correction however paved the best way for a 130% rise towards the tip of the yr, 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, comparable dangers emerge. The Trump administration is Bitcoin-friendly, however a future administration might flip hostile, leveraging centralized hashrate to manage the community. Not like China’s ban, a future U.S. authorities may attempt to regulate or manipulate mining, utilizing government powers like sanctions to censor transactions — a menace 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 might allow resistance to federal overreach. In states with important mining exercise, officers and the general public may argue that manipulating the business harms Bitcoin’s worth, impacting traders. Such resistance might 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 reasonably than cash flows, doubtlessly decreasing the specter of financial censorship. This pivot buys Bitcoin time, as centralized hashrate could also be a mushy goal for federal intervention.
Nonetheless, American Bitcoiners should keep proactive. Deepening Bitcoin adoption to embed it broadly within the financial system and all through the world might deter censorship, as assaults on the community would hurt private wealth, spurring backlash. Historical past additionally exhibits miners adapt when displaced — China’s ban proved that — however governments study. A future U.S. administration may not ban mining however search to manage it, exploiting centralization.
The Bitcoin business faces a essential 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.
