Bitcoin's mining difficulty dropped 10.09% at block 953,568 on Sunday, marking the second-largest negative adjustment of 2026 and the 11th-largest downward move in the network's history. The reset reduces the computational work required to mine a block, giving surviving miners roughly 11% more bitcoin per unit of active hashrate. That improvement is real, but it does not push most operators into profitability: blended all-in production costs across the industry sit between $77,000 and $90,000 per BTC, well above the spot price of approximately $63,957 as of June 13.

What the numbers show

Difficulty fell from 138.96 trillion to 124.93 trillion. Bitcoin's protocol recalibrates automatically every 2,016 blocks, targeting an average block time of 10 minutes. When hashrate drops and blocks slow down, the algorithm lowers the difficulty threshold so the remaining miners can keep processing transactions at roughly the intended pace. This cycle ran 15.6 days against the 14-day target, a gap that confirms meaningful hashrate came offline during the period. Galaxy Research, as reported by Blockonomi, noted the epoch extension alongside a roughly 15% price slide that compressed miner margins through the window. The network hashrate hit a trough near 861 exahashes per second (EH/s) on June 10, down sharply from approximately 1 zettahash per second (ZH/s) in late May, before partially recovering to a range of approximately 894 to 954 EH/s in subsequent days.

The hashprice, a measure of daily revenue per unit of mining power, fell below $30 per petahash per second. As TheEnergyMag observed, that level pushes more sites close to or below gross breakeven, before accounting for debt payments or overhead. Older machines and operations with higher electricity costs are the first to shut down when revenue compresses.

A year of sustained pressure

This adjustment does not stand alone. The year's largest negative move came on February 7, when difficulty fell 11.16%, the 10th-largest drop in Bitcoin's history. A smaller decline of 7.76% followed in March. A brief +1.72% uptick on May 29 reversed within two weeks. The pattern reflects an industry still absorbing the April 2024 halving, which cut the block subsidy from 3.125 BTC to 1.5625 BTC. Spot prices fell roughly 50% from October 2025 highs near $124,000 to lows near $65,000 by February 2026, and the current price of approximately $63,957 sits marginally below even those February lows, meaning the economics have not recovered from that trough.

The AI factor

A structural shift is accelerating the hashrate contraction beyond pure price dynamics. Large North American mining companies are converting data centre capacity to high-performance computing (HPC) and AI workloads, where margins are currently stronger. Global hashrate fell 5.8% quarter-over-quarter in Q2 2026 to 1,004 EH/s, which available data from Hashrateindex and BlockEden identifies as the first quarterly decline in six years. Bitfarms redomiciled to the United States, rebranded as Keel Infrastructure, and exited Bitcoin mining as its primary business. CEO Ben Gagnon stated plainly: "We are no longer a Bitcoin company, we are an infrastructure-first owner and developer for HPC/AI data centers across North America." Hut 8, TeraWulf, Riot Platforms, and MARA Holdings are all moving in similar directions. The sector has collectively signed more than $70 billion in AI and HPC contracts, and some companies could derive up to 70% of revenue from AI by the end of this year.

Regional stakes: Ethiopia, Pakistan, and Indonesia

The AI pivot is almost entirely a North American and East Asian story, and that asymmetry matters for developing-world operators who have no equivalent pathway to HPC infrastructure.

Ethiopia currently holds about 2.5% of global hashrate (roughly 25 EH/s), ranking eighth in the world. Operators there run primarily on cheap hydroelectric power from the Grand Ethiopian Renaissance Dam, so the difficulty drop provides a genuine yield improvement on existing deployments. Ethiopia generated approximately $55 million in Bitcoin mining revenues over a 10-month period in 2024, though that figure is likely lower in the current price environment, and it illustrates the tangible economic stakes for a government managing a scarce electricity grid. That grid constraint is precisely why Ethiopia froze new mining power permits in mid-2025, after crypto miners consumed 27% of total electricity distribution. Existing operations can continue, but scaling up to capture more of the difficulty-adjusted opportunity is blocked for now. The GERD is set to add more than 5,000 MW to the national grid over time, a development that could eventually reopen the question of available capacity for miners if permit policy is revisited.

Pakistan tells a different story of rapid expansion hitting a ceiling. The country grew from 0.3 EH/s to 4 EH/s between 2025 and early 2026, one of the fastest expansions globally, after the government allocated 2,000 megawatts of surplus power to mining and AI data centres. That policy framework was established through the Pakistan Crypto Council and the newly created Pakistan Virtual Assets Regulatory Authority (PVARA), which introduced tax holidays and customs duty exemptions on equipment to attract operators, giving the expansion a more durable institutional foundation than ad hoc incentives alone. Hashrate moderated to around 3 EH/s in Q2 as the price environment deteriorated. Operations running on coal-fired electricity face steeper margin compression than hydro-powered rivals, making the difficulty relief less impactful in practice. Pakistan does, however, hold substantial renewable energy potential: an estimated 50,000 MW of wind capacity in the Gharo-Keti Bandar corridor, alongside hydropower and solar resources, offers a longer-term pathway toward the lower-cost power profiles that make mining more structurally viable.

Indonesia rounds out the regional picture. Ranking approximately tenth globally, the country contributes an estimated 1.8 to 2.1% of total hashrate (roughly 18 to 22 EH/s), making it the second-most significant mining nation across South and Southeast Asia and a market that will feel the difficulty adjustment in proportion to its growing footprint.

What comes next

The difficulty drop buys time for miners still online, but it resolves nothing structurally. CoinShares projects hashrate could reach 1.8 ZH/s by end-2026, contingent on bitcoin returning above $100,000, according to a forecast reported by Intellectia.ai. Texas miners are also in the early weeks of ERCOT's Four Coincident Peaks season, a grid management program that incentivises voluntary curtailment during summer peak-demand hours, which will continue suppressing hashrate through September regardless of price. Until spot price closes the gap with production costs, the industry is managing a prolonged squeeze rather than recovering from a temporary shock.
