According to FinanceFeeds, Tether-supported large agricultural company Adecoagro plans to launch a Bitcoin mining operation powered by electricity generated from sugarcane processing in Brazil, with an initial capacity of 10 megawatts, approximately 1,280 mining machines, expected to start around July 1, 2026. Adecoagro's business encompasses sugar, ethanol, rice, dairy products, and renewable energy, and Tether previously acquired a majority stake in the company.The mining project will utilize electricity generated from sugarcane residue (bagasse), and the company has over 230 megawatts of renewable energy generation capacity in South America. Brazil is one of the world's largest sugarcane producers, with a mature ethanol and bioenergy industry. If the pilot is successful, other agricultural and renewable energy producers may view mining as a flexible demand source for surplus electricity.

According to Bits.media, a large illegal cryptocurrency mining operation was discovered in the city of Nizhny Tagil in Sverdlovsk Oblast, Russia, and the nearby city of Kushva. The mining operation was hidden in an abandoned industrial park and deployed about 10,000 mining machines, which were dismantled by a joint operation of the Federal Security Service of the Russian Federation, the police, and the power company.Local power companies estimate that the losses caused by the long-term illegal electricity usage of this mining operation amount to nearly 1 billion rubles (approximately 12.7 million USD). Investigators stated that its electricity consumption was sufficient to meet the lighting needs of a small city. Law enforcement has arrested three suspects, who are currently under house arrest and are being investigated for "causing property damage through deception or abuse of trust." Under Russian law, those involved could face up to 5 years in prison.Investigations revealed that the operators of the mining site accessed the power grid through intermediaries and allegedly tampered with electricity meter data to cover up the actual electricity usage. Law enforcement agencies stated that the actual electricity consumption of the mining operation was about twice the approved quota. The local energy department initially launched an investigation due to frequent voltage fluctuations, power outages, and equipment failures in the abandoned factory area, ultimately pinpointing the location of the mining operation. A local television station also produced a documentary titled "Mining" to document this operation.

According to Bits.media, the Italian energy company Alps Blockchain has partnered with the Bolivian company Qurubiqa to launch Bitcoin mining at a dormant 127-megawatt natural gas power plant in the Cochabamba region of Bolivia. The mining site currently consumes about 27 megawatts of power, with a hash rate of 1.23 EH/s, and plans to increase power consumption to 45 megawatts by the end of the year. The mining equipment directly uses the electricity generated by the power plant and is not connected to the public grid. Due to Bolivia facing a currency crisis and a shortage of US dollars, project participants settle in US dollars.

Wu Jihan stated on platform X that the current solar energy issue in Europe is no longer just about increasing power generation, but rather the lack of sufficient flexible power demand to absorb excess energy. He cited the latest analysis from the energy research organization Pexapark, which indicates that the phenomenon of "self-cannibalization" in European photovoltaics is rapidly worsening.Wu Jihan pointed out that the speed of solar deployment in Europe has outpaced the construction of grid system flexibility. In addition to energy storage, grid expansion, and demand response, Europe should also pay attention to interruptible loads, including Bitcoin mining and other computational loads. These types of loads can be activated when electricity is abundant and shut down when the grid is tight, thus becoming the "last buyer" of excess renewable energy, reducing curtailment, improving the profitability of photovoltaic projects, and enhancing the profitability and financing feasibility of investments in generation and grid infrastructure.

According to Bits Media, the Russian government has expanded the scope of information that miners and mining infrastructure operators must submit to the tax authorities. Under the new regulations, the national registry of miners and operators must include network address data for equipment used in cryptocurrency mining (ASIC miners). The Russian Ministry of Finance stated that this move aims to simplify the regulation of digital asset transactions and the investigation of violations. Additionally, grid operators will be able to more accurately monitor the infrastructure load in areas with a high concentration of mining capacity.According to the law, government agencies, courts, the Bank of Russia, and grid operators can access the information in the miners' registry. The Federal Tax Service is responsible for maintaining the registry of miners and mining infrastructure operators. Under current law, miners and infrastructure operators (such as mining pools) must submit and regularly update the following information: for mining equipment, details such as manufacturer, model, serial number, algorithm, hash rate, power consumption, and operating mode. Regarding mining: the amount and type of cryptocurrency mined, mining pools, and links to online statistics.

According to Livecoins, the property crime investigation department DEIC of São Paulo, Brazil, in collaboration with the electricity company CPFL Piratininga, conducted an operation that seized approximately 1,400 Bitcoin mining machines suspected of operating with stolen electricity. It is estimated that the amount of stolen electricity is enough to supply about 2,000 households for a month. Although Bitcoin mining is not illegal in Brazil, the focus of the actions by CPFL and DEIC is on the theft of electricity.

According to Zhejiang Daily, recently, the Ningbo Customs Anti-Smuggling Bureau successfully dismantled multiple criminal gangs smuggling virtual currency "mining machines" through in-depth operations and meticulous investigations, effectively cutting off an illegal industrial chain.Previously, during a routine inspection of a batch of imported express shipments declared as "industrial blockers," Ningbo Customs discovered that the actual goods did not match the declaration and were, in fact, virtual currency "mining machines." Customs officers quickly transferred this lead to the anti-smuggling department. After receiving the report, the Ningbo Customs Anti-Smuggling Bureau immediately assembled a task force by drawing on elite personnel, and through data analysis and clue investigation, gradually clarified the organizational structure and operational model of the criminal network. When the timing was right, they decisively struck, simultaneously conducting net-seizing operations in Dongguan, Shenzhen, and other locations, successfully dismantling multiple smuggling gangs of mining machines.Upon investigation, it was confirmed that this series of cases seized over 400 illegal entry mining machines of brands such as Ant L9 and Ice River KS3. The investigation revealed that the smuggling gang led by Liao, in order to make illegal profits, procured "mining machines" from overseas suppliers, disassembled the whole machines, and misreported the product names to smuggle them into the country through international express channels from ports in Ningbo, Guangzhou, and other places. After the goods entered the country, the gang reassembled them, either selling them directly domestically or transporting them to hidden "mining sites" in Xinjiang, Hunan, and other places to engage in illegal virtual currency "mining" activities. At the same time, they utilized virtual currencies like USDT for cross-border payment settlements to evade financial supervision.
