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. “The U.S. has solidified its position as the largest global mining hub (75.4% of reported activity),” the CCAF reports, based on a survey of 49 mining firms representing nearly half the Bitcoin network’s hashrate. 

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’s future?

Howard Lutnick, U.S. Secretary of Commerce and former CEO of Cantor Fitzgerald, recently shared insights into the Trump administration’s vision to position the U.S. as a Bitcoin superpower. “It’s like gold. To me. It’s a commodity,” Lutnick said in an interview with Frank Corva of Bitcoin Magazine, highlighting Bitcoin’s fixed supply of 21 million coins. He outlined plans to “turbocharge” U.S. mining through the Commerce Department’s Investment Accelerator, which streamlines permits for miners to build off-grid power plants. “You can build your own power plant next to [your data center]. I mean, think about that for a second,” he said.

This pro-business stance has fueled America’s mining boom, but the CCAF’s findings suggest a downside: centralization. For years, Bitcoiners worried about China’s dominance, which peaked at 65–75% of global hashrate before its June 2021 mining ban. “In 2019, China dominated global Bitcoin mining, accounting for 65–75% of the total Bitcoin network,” a 2025 Nature Communications study notes. When China banned mining, hashrate dispersed globally, 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’s resilience.

While China’s 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’s ban, a future U.S. government might try to regulate or manipulate mining, using executive powers like sanctions to censor transactions — a threat amplified by mining’s concentration.

The U.S.’s 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’s value, impacting investors. Such resistance could preserve the network’s integrity.

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.

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 — China’s ban proved that — but governments learn. A future U.S. administration might not ban mining but seek to control it, exploiting centralization.

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’s mining dominance? As Lutnick’s vision unfolds, Bitcoiners must ensure this sovereign money remains resilient, regardless of who holds power.

With all the current bearish sentiment and macroeconomic uncertainty swirling around both Bitcoin and the broader global economy, it might come as a surprise to see miners as bullish as ever. In this article, we’ll unpack the data that suggests Bitcoin miners are not just staying the course, they’re accelerating, doubling down at a time when many are pulling back. What exactly do they know that the broader market might be missing?

For a more in-depth look into this topic, check out a recent YouTube video here:
Why Bitcoin Miners Are Doubling Down Right Now

Bitcoin Hash Rate Going Parabolic

Despite Bitcoin’s recent price underperformance, the Bitcoin Hashrate has been going absolutely vertical, breaking all-time highs with seemingly no regard for macro headwinds or sluggish price action. Typically, hash rate is tightly correlated with BTC price; when price drops sharply or remains stagnant, hash rate tends to plateau or decline due to economic pressure on miners.

Yet now, in the face of heightened global tariffs, economic slowdown, and a consolidating BTC price, hash rate is accelerating. Historically, this level of divergence between hash rate and price has been rare and often significant.

Bitcoin Miner Difficulty, a close cousin to hash rate, just saw one of its largest single adjustments upward in history. This metric, which auto-adjusts to keep Bitcoin’s block timing consistent, only increases when more computational power floods the network. A difficulty spike of this magnitude, especially when paired with poor price performance, is nearly unprecedented.

Again, this suggests that miners are investing heavily in infrastructure and resources, even when BTC price does not appear to support the decision in the short term.

Adding further intrigue, the Hash Ribbons Indicator, a blend of short and long-term hash rate moving averages, recently flashed a classic Bitcoin buy signal.

When the 30-day moving average (blue line) crosses back above the 60-day (purple line), it signals the end of miner capitulation and the beginning of renewed miner strength. Visually, the background of the chart shifts from red to white when this crossover occurs. This has often marked powerful inflection points for BTC price.

What’s striking this time around is how aggressively the 30-day moving average is surging away from the 60-day. This is not just a modest recovery, it’s a statement from miners that they are betting heavily on the future.

The Tariff Factor

So, what’s fueling this miner frenzy? One plausible explanation is that miners, especially U.S.-based ones, are trying to front-run the impact of looming tariffs. Bitmain, the dominant producer of mining equipment, is now in the crosshairs of trade policies that could see equipment prices surge by 30–50%, potentially to even over 100%!

Given that over 40% of Bitcoin’s hash rate is controlled by U.S.-based pools like Foundry USA, Mara Pool, and Luxor, any cost increase would drastically reduce profit margins. Miners may be aggressively scaling now while hardware is still (relatively) cheap and available.

Bitcoin Miners Keep Mining

Hashprice, the BTC-denominated revenue per terahash of computational power, is at historical lows. In other words, it’s never been less profitable in BTC terms to operate a Bitcoin miner on a per-terahash basis. Typically, we see hash price increase toward the tail-end of bear markets, as competition fades and weaker players exit the space.

But that’s not happening here. Despite terrible profitability, miners are not only staying online, they’re deploying more hash power. This could imply one of two things; either miners are racing against deteriorating margins to front-load BTC accumulation, or, more optimistically, they have strong conviction in Bitcoin’s future profitability and are buying the dip aggressively.

Bitcoin Miners Conclusion

So, what’s really happening? Either miners are desperately front-running hardware costs, or, more likely, they’re signaling one of the strongest collective votes of confidence in the future of Bitcoin we’ve seen in recent memory. We’ll continue tracking these metrics in future updates to see whether this miner conviction is proven right.
