Mining difficulty dropped sharply for the first time in months, down 7.48%, following a stretch of elevated miner activity. The decline coincides with intensifying summer curtailments across the U.S., as heatwaves and grid constraints forced several major public miners, including MARA and Cipher, to cut back operations, dragging down network hashrate for weeks.
Miner revenue rose modestly, supported by stable BTC prices and a surge in block space demand. While the mempool cleared by over 96%, the estimated transaction value jumped more than 900%, pointing to fewer but significantly larger transfers. However, transaction fees dropped by over 50%, limiting the miner revenue upside from the difficulty adjustment.
Bitcoin Miners Expand Grid Ties and Self-Mining Capacity
Hut 8 has signed five-year capacity contracts with Ontario’s Independent Electricity System Operator (IESO) to supply up to 310 MW across four natural gas-fired power plants. These agreements will generate stable, predictable income for Hut 8’s joint venture Far North Power Corp. Similar to arrangements in Texas, these contracts position Hut 8 as a grid-stabilizing power provider, diversifying revenue beyond mining rewards, especially crucial post-halving.
Meanwhile, Cipher Mining announced it has exceeded expectations at its new Black Pearl site, boosting its self-mining capacity with the phased rollout of new rigs. The facility began hashing in late June and mined 160 BTC that month, of which 58 were sold. Cipher now holds 1,063 BTC.

Bitcoin Miners Hold Steady Despite 100% Profit Margins
Despite earning over double their production costs, Bitcoin miners are showing surprising restraint, with on-chain data revealing minimal selling activity. Marathon Digital, for example, currently mines BTC at an average cost of $51,700 while market prices exceed $105,000. Yet, even with these sizable margins, miners are largely holding onto their coins. This behaviour marks a significant shift from earlier cycles, where miners were more likely to sell into rallies to lock in profits.
Analysts suggest several reasons behind this trend. Major players may be anticipating further price growth, using BTC as collateral, or operating from a stronger financial footing following the 2024 halving. Marathon’s hash rate has surged from 6.9 EH/s in early 2023 to 46.1 EH/s in 2025. The key takeaway: miners now appear to be acting more like long-term institutional stakeholders than short-term profit-takers.

Putin Defends Regional Bitcoin Mining Bans Amid Power Shortages
President Vladimir Putin has justified Russia’s growing restrictions on crypto mining, pointing to escalating electricity shortages in certain regions. During a national development forum, Putin explained that regional governors had pushed for intervention after surging mining activity led to local energy deficits, hindering infrastructure and industrial development. In response, the government has introduced partial or full bans across nearly a dozen territories, including Siberia and the North Caucasus. Putin cited these restrictions as necessary to ensure a balanced use of national energy resources.
Compounding the issue, Russia raised electricity transmission and distribution rates in July 2025 by over 11%, further squeezing mining profitability. While regions like Irkutsk had become mining hotspots due to cheap power, rising costs now threaten the competitiveness of Russia’s mining sector. Experts warn that legal, tax-paying miners are bearing the brunt of the crackdown, while illegal operations may persist underground. With investor confidence waning, authorities are exploring ways to relocate miners to energy-rich northern areas while tightening enforcement in power-starved regions.

Ninjas in Pyjamas Parent Company Enters Bitcoin Mining with $6.5M Monthly Target
NIP Group, the parent company of renowned esports team Ninjas in Pyjamas, has officially entered the Bitcoin mining industry. The company aims to generate 60 BTC per month, worth approximately $6.5 million at current prices, by deploying 3.11 EH/s of hashrate. A new internal division, Digital Computing Division, has been launched to oversee operations and drive future mining investments. While NIP has yet to disclose how it plans to manage its Bitcoin holdings, the move reflects a shift beyond esports into digital infrastructure.
Co-founder and co-CEO Hicham Chahine emphasized that NIP is no longer just a gaming company, but one expanding into computing and operational capacity. Despite the bold announcement, investors reacted cautiously. Shares fell 17% after the news, continuing a broader decline from their July 2024 peak. The move echoes the strategy of firms like MicroStrategy, which have grown by accumulating Bitcoin as a treasury asset.

Summer Heat Forces Curtailments, Slashing Bitcoin Output for US Miners
Bitcoin mining production in the U.S. fell sharply in June as high temperatures triggered widespread curtailments. Major public miners like Cipher Mining and Marathon Digital (MARA) reported lower-than-expected realized hashrates despite expanding their installed capacity. Cipher, which ramped up its installed hashrate to 16.8 EH/s, only achieved 10.58 EH/s on average (just 62.95% utilization) due to its aggressive 4CP avoidance strategy, aimed at limiting grid costs during peak demand. Meanwhile, MARA saw its realized hashrate drop nearly 20% to 47.13 EH/s as it contended with weather-related curtailments and temporary equipment issues.
The seasonal pattern of summer curtailments once again shows the vulnerability of Bitcoin miners to grid constraints during heatwaves. While recent geopolitical events have drawn speculation around the latest hashrate drop, the concrete impact of North American grid conditions appears to be a dominant factor behind it. With Bitcoin’s network hashrate falling from a peak of 950 EH/s to around 850 EH/s, miners are expected to further adjust their strategies through the summer to cope with energy volatility.

IMF Rejects Pakistan’s Plan to Subsidize Bitcoin Mining Electricity
Pakistan’s ambitions to establish a government-led Bitcoin reserve have hit a major snag after the International Monetary Fund (IMF) blocked a proposal to subsidize electricity for crypto mining. Secretary of Power Dr. Fakhray Alam Irfan confirmed the IMF’s firm opposition to targeted subsidies, even during periods of energy surplus. The plan aimed to allocate 2,000 MW of electricity to support Bitcoin mining and AI data centers, spearheaded by the Pakistan Crypto Council. The initiative was intended to attract foreign investment, boost employment, and use Pakistan’s strategic geographical position for digital infrastructure.
With additional scrutiny from the World Bank and other global lenders, the future of Pakistan’s Bitcoin reserve project remains uncertain. Despite these challenges, Pakistan continues to push for a crypto-friendly environment, having recently formed the Pakistan Digital Assets Authority and introduced new crypto regulations. Officials maintain that the initiative was inspired by the U.S., although critics warn of mounting financial risks.
