A groundbreaking study from the Cambridge Centre for Alternative Finance (CCAF) claims that the United States now dominates Bitcoin mining, controlling as much as 75.4% of the global hashing power. \u201cThe U.S. has solidified its position as the largest global mining hub (75.4% of reported activity),\u201d the CCAF reports<\/a>, based on a survey of 49 mining firms representing nearly half the Bitcoin network\u2019s hashrate.\u00a0<\/p>\n This concentration, equating to roughly 600 exahashes per second (EH\/s) of the global 796 EH\/s, raises a pressing concern: Is Bitcoin mining becoming dangerously centralized in the U.S., and what risks does this pose for the emerging asset\u2019s future?<\/p>\n Howard Lutnick, U.S. Secretary of Commerce and former CEO of Cantor Fitzgerald, recently shared insights into the Trump administration\u2019s vision to position the U.S. as a Bitcoin superpower. \u201cIt\u2019s like gold. To me. It\u2019s a commodity,\u201d Lutnick said in an interview<\/a> with Frank Corva of Bitcoin Magazine, highlighting Bitcoin\u2019s fixed supply of 21 million coins. He outlined plans to \u201cturbocharge\u201d U.S. mining through the Commerce Department\u2019s Investment Accelerator, which streamlines permits for miners to build off-grid power plants. \u201cYou can build your own power plant next to [your data center]. I mean, think about that for a second,\u201d he said.<\/p>\n This pro-business stance has fueled America\u2019s mining boom, but the CCAF\u2019s findings suggest a downside: centralization. For years, Bitcoiners worried about China\u2019s dominance, which peaked at 65\u201375% of global hashrate before its June 2021 mining ban. \u201cIn 2019, China dominated global Bitcoin mining, accounting for 65\u201375% of the total Bitcoin network,\u201d a 2025 Nature Communications<\/em> study notes<\/a>. When China banned mining, hashrate dispersed globally<\/a>, with many operations relocating to the U.S., drawn to states with abundant energy and favorable policies. This shift caused a 50% market correction but paved the way for a 130% rise toward the end of the year, demonstrating the market\u2019s resilience.<\/p>\n While China\u2019s historical hashrate concentration never led to network abuse, it was a constant concern. Now, with the U.S. holding 75% of hashrate, similar risks emerge. The Trump administration is Bitcoin-friendly, but a future administration could turn hostile, leveraging centralized hashrate to control the network. Unlike China\u2019s ban, a future U.S. government might try to regulate or manipulate mining, using executive powers like sanctions to censor transactions \u2014 a threat amplified by mining\u2019s concentration.<\/p>\n The U.S.\u2019s federal structure offers a potential safeguard. The division of powers between states and the federal government could enable resistance to federal overreach. In states with significant mining activity, officials and the public might argue that manipulating the industry harms Bitcoin\u2019s value, impacting investors. Such resistance could preserve the network\u2019s integrity.<\/p>\n The weakening of the U.S. monetary sanctions regime might play to our advantage. Following the 2022 seizure of Russian treasuries, nations misaligned with U.S. policy have reduced U.S. bond purchases, undermining the fiat rails abused in sanctions. The Trump administration is shifting toward tariffs to control goods rather than money flows, potentially reducing the threat of monetary censorship. This pivot buys Bitcoin time, as centralized hashrate may be a soft target for federal intervention.<\/p>\n Nevertheless, American Bitcoiners must stay proactive. Deepening Bitcoin adoption to embed it widely in the economy and throughout the world could deter censorship, as attacks on the network would harm personal wealth, spurring backlash. History also shows miners adapt when displaced \u2014 China\u2019s ban proved that \u2014 but governments learn. A future U.S. administration might not ban mining but seek to control it, exploiting centralization.<\/p>\n The Bitcoin industry faces a critical juncture. With as much as 75.4% of hashrate in the U.S., even low estimates of 50% present a centralization risk that looms large. Should we diversify globally or lean into America\u2019s mining dominance? As Lutnick\u2019s vision unfolds, Bitcoiners must ensure this sovereign money remains resilient, regardless of who holds power.<\/p>\n![\"Bitcoin](\"https:\/\/cdn-ilddnad.nitrocdn.com\/XgjmJNBNBbZQEuHAZVzgTqmzytAUTSfp\/assets\/images\/optimized\/rev-d9b18a2\/bitcoinmagazine.com\/wp-content\/uploads\/2025\/04\/image-3-1024x490.png\" "\\"Bitcoin")
