Marathon Digital Holdings has initiated a pilot project in Finland. The project recycles heat from Bitcoin mining to warm a local community in the Satakunta region, which has 11,000 residents. The 2-megawatt data center began operations in May. "This pilot project in Finland is a critical step forward in our strategy to expand globally and innovate sustainably," Fred Thiel, Marathon's chairman and CEO, said. Thiel also emphasized the dual benefits of producing digital assets and heating homes. It is the company's first district heating project and its European debut. District heating involves centrally heating water and distributing it to local buildings. Finland is known for its clean energy mix. The country relies heavily on biomass for district heating. The project aims to reduce carbon emissions and operating costs by using heat from data centers. Marathon's "Heating with Hashes" report provides context for the project. "Europe's colder climate has given rise to an extensive network of district heating systems," the report states. It notes that data centers benefit from the cooler temperatures in Europe. The report highlights a unique opportunity. Data centers in the EU consume a higher share of electricity compared to the global average. These facilities generate significant heat, which can be recycled for district heating. Marathon sees this as a win-win situation. "One industry needs heat, while the other generates plenty of it," the report explains. This approach could reduce costs and waste while decreasing reliance on carbon-emitting heat sources. The project aligns with Marathon's sustainability goals. The mining company now operates twelve sites on four continents. The company has high hopes with the heating market. Marathon aims to enhance its sustainability portfolio through heat recycling. It also seeks to explore new revenue streams. These efforts align with its goal of achieving zero-cost power for digital asset computing.

Coolpad, a Chinese telecom giant, is entering the world of Bitcoin mining. Quite an unexpected move for a company that is known for cheap mobile phones and accessories. Anyway, Coolpad has just announced it will acquire 2,700 Bitcoin mining servers from Hong Kong-based JingYun Intelligent Technology. That's up to 1,504,800 TH/s of mining capacity. Coolpad is spending $13.5 million for this purchase. The rigs will be installed in a yet undisclosed locations in North America. That's pretty understandable, as Bitcoin mining is prohibited in China. The Shenzhen-based company has already made some moves into crypto space. In May, Coolpad announced a $28 million investment plan to purchase shares in some crypto asset companies, including CleanSpark, ARK 21Shares Bitcoin ETF, Bitwise Bitcoin ETF, Grayscale Bitcoin Trust, and Hashdex Bitcoin Futures ETF. Coolpad isn't the only telecom company to enter Bitcoin mining recently. T-Mobile Deutsche Telekom will start mining Bitcoin this year. German company has been operating a Bitcoin node since 2023. This year the company launched its own Bitcoin Lightning Network nodes. And now the bigger anouncement was unveiled. Speaking at BTC Prague, Dirk Röder, head of Web3 infrastructure and solutions at Deutsche Telekom, confirmed that the communications giant will start mining Bitcoin.

Bitcoin network hashrate always declined in summer time. This year it might get even worse. Summer heatwaves can have a deep impact on Bitcoin mining. Miners have to deal with the excessive heat throughout whole year, but with global warming becoming more prominent the problem gets pretty serious. Halving that occurred earlier this year has already made its impact on miners. With their profits cut twice miners see much less profit in maintaining network's functionality. Miners have to be looking for more contemporary, energy efficient equipment. Hashrate needs to be raising all the time. Heatwaves might be a specifically harsh problem this year. As we all know, miners use extremely powerful machines (ASICs) that give off a lot of heat as a result of their computations. They can reach very high temperatures without proper cooling measures in place. So, to ensure their ASICs are safe, miners might have to resort to turning them off periodically to let them cool down. Energy consumers around them will be turning their air conditioning more frequently and that additional demand might hurt miners also. 37% of all world mining operations are located in the U.S. Most part of it - in steamy Texas. That might reflect on hashrate and create "jams" in blockchain network traffic. Faster Bitcoin transaction will require higher mining fees. Some analysts note that the hashrate has already started to come down since reaching an all-time high in March. In June it is 10% lower than it was a month earlier.

T-Mobile Deutsche Telekom will start mining Bitcoin. That might come as a surprise, but not a to those who have been following crypto news lately. German telecom giant is going crypto since last year. Company's expansion into crypto-based activities began with Polygon validation. Now the company wants to enter the big game. Deutsche Telekom is about to enter the mining business. Since Ethereum's switch from Proof-of-Work to Proof-of-Stake in 2022 the only big mining business is the one with Bitcoin involved. The German telecommunications firm has been operating a Bitcoin node since 2023. This year the company launched its own Bitcoin Lightning Network nodes. And now the bigger anouncement was unveiled. Speaking at BTC Prague, Dirk Röder, head of Web3 infrastructure and solutions at Deutsche Telekom, confirmed that the communications giant will start mining Bitcoin. Röder actually jokingly called mining a 'digital monetary photosynthesis'. And that' is so charming. Market's reaction seem very positive. According to a famous analyst BTCGandalf, Deutsche Telekom's decision to enter Bitcoin mining is staggering. 'What a time to be alive,' he wrote on X. Deutsche Telekom is one of the world's leading integrated telecommunications companies. Established in 1995, the company provides a wide range of services. Those include fixed-network and mobile communications, internet, and IPTV products and services for consumers. Company has a significant presence in Europe and the United States. It's know for its innovations, but was silent about its crypto ambitions before 2023.

Donald Trump, a Presidential candidate and a felon, met some crypto miners and made some unbelievable statements. Bitcoin to be Made in USA, he said. As Yellow.com already highlighted, Trump wants to be America's first Bitcoin President. He started with accepting crypto donations for his campaign. Now he is going even further than that. According to Cointelegraph, Trump showed his support for the crypto mining industry after executives pitched him on how they could strengthen the electrical grid and create new jobs. Trump claims that “all the remaining Bitcoin to be MADE IN THE USA!!!” as it would help the country be “energy dominant.” The ex-president also mentioned the dangers of CBDC (central bank digital currency). Trump thinks Bitcoin is the country’s “last line of defense” against CBDC. This bold statement comes despite the fact that Federal Reserve Chair Jerome Powell said in March the U.S. was “nowhere near recommending or let alone adopting a central bank digital currency in any form.” Trump might be referring to some of his supporters. They often claim that Joe Biden's hatred towards cryptocurrencies helps China, Russia and radical communists. For instance, Biden has proposed a 30% electricity tax on Bitcoin miners in the country. Miners aren't happy, to say the least.
