Centralization of Bitcoin Mining in the USA: Risk or Opportunity?
According to a recent report by the Cambridge Centre for Alternative Finance (CCAF), the United States now controls 75.4% of the global Bitcoin hashrate, which equates to 600 exahashes per second out of a worldwide total of 796 EH/s. This unprecedented concentration has reignited the debate about centralization risks in the Bitcoin ecosystem. Howard Lutnick, former CEO of Cantor Fitzgerald and current US Secretary of Commerce, outlined the Trump administration’s vision to position the US as a Bitcoin superpower. Lutnick compared Bitcoin to gold, emphasizing its capped supply of 21 million coins, and described plans to support mining through the Department of Commerce’s Investment Accelerator Program, which streamlines permits for off-grid power plants for miners.
While this pro-business stance has fueled a mining boom in the US, the CCAF’s findings highlight the potential downside: centralization. Historically, China’s dominance in mining was a concern, but it never led to network abuse. After China’s mining ban in June 2021, much of the hashrate shifted to the US. The Trump administration’s Bitcoin-friendly approach could be reversed by future governments, which might use the centralized hashrate to control or censor the network, possibly through sanctions or regulatory measures. However, the US federal structure, with its division of powers between states and the federal government, could provide some protection against overregulation. States with significant mining activity may resist federal attempts to manipulate the industry, arguing that such actions would harm Bitcoin’s value and investors.
- The US controls 75.4% of the global Bitcoin hashrate (600 EH/s of 796 EH/s).
- Trump administration supports mining through streamlined permits for off-grid power plants.
- Centralization could enable future US governments to regulate or censor the network.
- The federal structure may offer resistance to overregulation.
The weakening of the US sanctions regime, especially after the seizure of Russian state bonds in 2022, has led some countries to reduce their US bond purchases, undermining the fiat rails used in sanctions. The Trump administration is shifting towards tariffs to control trade flows, which could reduce the threat of monetary censorship. Nevertheless, American Bitcoiners must remain proactive. Deeper Bitcoin adoption in the economy could deter censorship, as attacks on the network would harm personal wealth and provoke backlash. The history of mining shows that miners adapt when displaced, as seen after China’s ban, but governments are also learning. A future US administration could exploit centralization to control mining.
With up to 75.4% of the hashrate in the US, even a conservative estimate of 50% poses a significant centralization risk. The industry faces a critical decision: should it diversify globally or rely on US dominance? As Lutnick’s vision takes shape, Bitcoiners must ensure the resilience of this sovereign money, regardless of who is in power.
| Country | Share of Global Hashrate | Hashrate (EH/s) |
|---|---|---|
| USA | 75.4% | 600 |
| Global | 100% | 796 |
Key Takeaway: The US’s dominance in Bitcoin mining presents both opportunities and significant risks of centralization, with potential regulatory and censorship implications depending on future government policies. (Source: it boltwise)

Bitcoin: The Impact of the 2028 Halving on Supply and Demand
The upcoming Bitcoin halving in 2028 is already casting its shadow and could significantly influence the dynamics of the cryptocurrency market. This regularly scheduled reduction in block rewards, occurring approximately every four years, is a core element of Bitcoin’s monetary policy. Its purpose is to control inflation and increase the scarcity of the digital asset. With the 2028 halving, the daily issuance of new Bitcoins will drop from 450 BTC in 2025 to 225 BTC in 2028, directly affecting miner incentives and long-term supply dynamics.
By April 2025, over 19.8 million Bitcoins had been mined, representing 94% of the total Bitcoin supply. The remaining Bitcoins to be mined until 2140 amount to about 1.144 million. After the 2028 halving, the number of Bitcoins left to be mined will fall below 500,000, further tightening scarcity. This structural scarcity is a key factor in many long-term valuation models, such as the stock-to-flow model, which highlights Bitcoin’s deflationary nature.
| Year | Daily New BTC Issued | Total BTC Mined | BTC Remaining to be Mined |
|---|---|---|---|
| 2025 | 450 | 19.8 million (94%) | 1.144 million |
| 2028 (post-halving) | 225 | ~20.3 million | <500,000 |
Another factor affecting Bitcoin’s availability is the number of lost or inaccessible coins. Estimates suggest that between 3 and 4 million Bitcoins are lost forever, further reducing the actual circulating supply. These losses often result from lost private keys, inaccessible wallets, or intentionally burned coins, contributing to market tightening long before 2140.
Institutional and governmental adoption of Bitcoin is also on the rise. By 2028, governments and large institutions could hold significant amounts of Bitcoin as strategic reserves. The introduction of spot ETFs and clearer regulatory frameworks is expected to encourage banks and asset managers to take long-term positions in Bitcoin, further reducing available supply. These developments could lead to a serious supply shock as demand rises and supply falls.
- 2028 halving reduces daily new BTC from 450 to 225.
- By April 2025, 94% of all Bitcoins had been mined.
- Estimated 3–4 million Bitcoins are lost and unrecoverable.
- Institutional adoption and ETFs may further reduce available supply.
The 2028 halving could also have a significant impact on Bitcoin’s price. With daily issuance dropping to just 225 BTC and increasing scarcity, the price could rise, especially if demand continues to grow. This deflationary structure could further solidify Bitcoin’s value as a strategic digital reserve asset.
Key Takeaway: The 2028 Bitcoin halving will intensify scarcity, with only 2.3% of the total supply left to be mined by 2140, and growing institutional adoption could trigger a supply shock and potentially drive prices higher. (Source: it boltwise)
