This week’s numbers show a reduction in total network hashrate, even as difficulty stayed flat. This points to operational reshuffles as inefficient miners exit the market. Canaan’s withdrawal from Kazakhstan and a South Texas site, which temporarily idled part of its fleet, along with Greenidge’s sale of its Mississippi facility, likely removed capacity and contributed to the dip.
Meanwhile, Bitcoin’s price saw a modest rise, and with difficulty unchanged, miners’ daily revenue edged higher. The increase in estimated transaction value suggests larger BTC transfers on-chain, even as the average transaction fee declined slightly. As for the mempool, its fluctuation is largely irrelevant here, as its total size remains far below the level that could meaningfully push fees upward.
Ethiopia Earns $55M From Surplus Hydropower via Bitcoin Mining
Ethiopian Electric Power has generated $55 million in just 10 months by redirecting excess hydroelectric capacity to Bitcoin mining, accounting for 18% of its annual revenue. The profits are being reinvested into rural electrification, including expanding transmission and distribution networks, to help bridge the nation’s energy access gap. Only 43% of Ethiopians had electricity in 2021.
The strategy uses otherwise stranded renewable energy, attracting mainly Chinese (80%), as well as Russian and U.S., mining firms, which also bring in technology transfer. The program supports Ethiopia’s National Electrification Program goal of universal power access by 2025. This illustrates how Bitcoin mining can monetize unused green energy while funding infrastructure growth.

French Lawmakers Propose Bitcoin Mining With Surplus Nuclear Energy
A group of French MPs is drafting legislation to authorize Bitcoin mining using excess electricity from the country’s nuclear power plants, operated by state utility EDF. France leads the EU in nuclear production, generating over half of the bloc’s output in 2023, yet more than two-thirds of the heat produced in the process is lost. Proponents describe the plan as a “secure and extremely profitable solution” that could turn unused capacity into economic value.
The proposal builds on a previously rejected June amendment that sought to evaluate crypto mining’s role in France’s energy mix. Similar surplus-energy mining projects are emerging globally, such as Pakistan’s commitment of 2,000 MW of underused coal plant capacity or Tether’s initiative to mine Bitcoin with renewable energy from South American agribusiness Adecoagro. France’s plan is still in its early stages but reflects a growing interest in monetizing stranded energy through mining.

Trump’s New Tariffs Target Mining Equipment Imports
The U.S. has implemented new tariffs of up to 21.6% on ASIC miners imported from Indonesia, Malaysia, and Thailand, ending a 90-day pause granted in April. While the 57.6% tariff on Chinese devices remains unchanged, the move significantly raises the cost of acquiring new hardware for American miners. Luxor Technology COO Ethan Vera warned that these rates make the U.S. one of the least competitive countries for importing mining rigs, prompting some buyers to shift orders to Canada and other markets with friendlier trade terms. Demand for used ASICs already in the U.S. is rising, with prices expected to climb by more than 20%.
Singapore-based BitFuFu CEO Leo Lu countered that U.S. miners could still retain an edge through cheap and renewable energy access, with expansion plans ongoing in states like Oklahoma, Texas, and Colorado. However, Vera noted that the tariffs could reshape global hashrate distribution, driving Chinese capital and equipment toward markets such as Russia, Canada, Northern Europe, Ethiopia, Brazil, and parts of South America, potentially altering the competitive landscape of Bitcoin mining.

Trump-Linked Miner Nears Nasdaq Debut via Merger
Shareholders of Gryphon Digital Mining have begun voting on a proposed all-stock merger with American Bitcoin Corp., a Hut 8 subsidiary co-founded by Eric Trump and backed by Donald Trump Jr. The deal, expected to close in early September, would create a new crypto mining venture with strong political ties and list it on Nasdaq under the ticker ABTC. Hut 8 will retain an 80% stake, while the Trump-backed American Data Centers will hold the remaining 20%.
American Bitcoin, launched in March, has a mandate to build a strategic Bitcoin reserve and has raised $220 million through a private placement to acquire BTC and mining equipment. Post-merger, existing stakeholders (including Hut 8 and the Trump sons) will collectively own about 98% of the new entity. Eric Trump will serve as chief strategy officer.

Iren Overtakes MARA in Bitcoin Production and Utilization
Sydney-based Iren Limited (IREN) has become the top mining company by hashrate, outpacing Marathon Digital (MARA) in both Bitcoin production and fleet utilization in July. Iren mined 728 BTC compared to MARA’s 703 BTC, running over 90% of its fleet versus MARA’s sub-75% utilization. The firm averaged 45.4 EH/s, generating record monthly revenue of $86 million and hardware profits of $66 million, boosted by strong mining economics and demand for its AI Cloud services.
In contrast, MARA maintained a pure Bitcoin mining model, while Iren also earned $2.3 million from its compute business. Bitcoin’s network hashrate surpassed 900 EH/s for the first time in July, showing that competition is rising. Miners also expanded their treasuries: MARA now holds 50,639 BTC (~$5.8B), CleanSpark increased to over 12,700 BTC, and Cipher Mining boosted holdings to 1,219 BTC.

Union Jack Oil to Mine Bitcoin Using West Newton Gas
Union Jack Oil plc has signed a non-binding letter of intent with Texas-based 360 Energy to launch a pilot Bitcoin mining project powered by natural gas from its West Newton site in Yorkshire. The initiative would convert stranded or flared gas into electricity for modular data centers, enabling on-site, low-carbon mining. The project aims to generate early revenue from the WNA-2 well before full-scale gas development, with feasibility studies indicating strong potential returns.
Executive Chairman David Bramhill described the plan as a creative way to unlock value from untapped resources and hinted at a possible Bitcoin treasury strategy if the pilot succeeds. The move is part of a new trend of legacy energy companies exploring BTC mining to monetize underused energy assets. If implemented, it could serve as a blueprint for integrating traditional energy production with digital asset infrastructure.

Greenidge to Sell Mississippi Bitcoin Mining Facility Amid Financial Strain
Greenidge Generation has agreed to sell its Columbus, Mississippi Bitcoin mining site to U.S. Digital Mining Mississippi, a subsidiary of competitor LM Funding America, for approximately $3.9 million. The deal, expected to close by September 16, excludes mining rigs and a nearby warehouse. The 6.4-acre facility only began operations in July 2024 but has been affected by Greenidge’s heavy debt load and increased costs from tariffs on imported equipment.
The sale is the latest consequence of the ongoing turmoil in the mining industry, particularly after Trump’s new tariff regime. For Greenidge, the divestment is a step toward reducing debt and focusing on more sustainable operations, while LM Funding expands its footprint in the U.S. mining sector.

Canaan Exits Kazakhstan and South Texas Mining Sites
Bitcoin mining rig maker Canaan has shut down operations at two locations: Kazakhstan and a low-performing hosting site in South Texas. This is part of a fleet optimization strategy. The exits contributed to a July production of 89 BTC, with realized hashrate dropping to 5.56 EH/s from 6.67 EH/s in May. About half of the affected machines are expected to be relocated and online again in August, with the rest following later.
The Kazakhstan withdrawal is part of a wider industry retreat from the country amid regulatory and operational uncertainty, while the South Texas closure could be explained by summer challenges including high energy prices and curtailment risks. Canaan now operates at 6.24 EH/s, or 78% of its deployed capacity, and has increased its Bitcoin treasury to 1,511 BTC under a policy to hold mined coins.
