Odaily News: Crypto asset management firm Grayscale estimates that Zcash mining rigs generate daily mining rewards roughly 2x those of Bitcoin mining rigs, and about 4x on a per-unit-of-electricity basis. Zcash mining activity has grown to more than 2.5x its level at the start of the year.Zach Pandl, head of research at Grayscale, said that at current valuations, Zcash mining profitability is relatively high, as token price gains have driven up mining rewards and encouraged more hash rate to join. Grayscale believes that more hash rate can support network security.The comparison uses the Bitmain S23 Hydro and Bitmain Z15 Pro as samples, assuming an electricity price of $0.05 per kilowatt-hour, full-load operation, and excluding transaction fees. Pool fees, cooling, other operating expenses, and equipment costs are not included in the calculation, and actual profitability is still affected by these factors.Bitcoin miners' total daily rewards are about $35 million, higher than Zcash's roughly $2 million. Grayscale's Zcash investment product assets under management surpassed $500 million on September 8 and recorded more than $70 million in cumulative external inflows. (Bitcoin.com News)

Odaily News: Bitcoin's Hashprice has increased by 20.41% over the past four days, rising from a daily rate of $31.80/PH/s on August 18 to $38.29/PH/s on August 22. Hashprice is used to measure mining revenue corresponding to a specific amount of hashrate, and this increase has boosted miner income.As of August 22, a total of 133 large, medium, and small mining pools, along with individual mining operations, contributed hashrate to the Bitcoin network. Mining pool Foundry USA led with 214.73 EH/s, followed by Antpool with 156.17 EH/s and F2pool with 110.62 EH/s, while ViaBTC recorded 91.02 EH/s.The Bitcoin network's total hashrate has risen to approximately 922 EH/s, approaching 1 ZH/s. In August, miners have so far earned $682.69 million from block subsidies and transaction fees, of which transaction fee revenue accounted for $5.14 million, lower than July's $875 million.On August 22, the average block interval on the Bitcoin network was 10 minutes and 5 seconds, with current data indicating an expected difficulty adjustment of approximately -1% for the day. Based on an electricity cost of $0.10 per kilowatt-hour, the Bitmain Antminer S23 Hydro 3U is projected to yield an estimated daily profit of $17.86. (Bitcoin.com News)

Odaily Planet Daily News Will McEvoy posted on X platform, stating that Cypherpunk Mining has officially launched. With 4.2 Gsol/s of Equihash hashrate deployed in the United States, it has already become the world's largest Zcash miner. The company signed a $33.333 million asset acquisition agreement with Winklevoss Capital to take over its fleet of Bitmain Z15 Pro miners previously deployed across the United States. The operation currently produces approximately 7,800 ZEC per month and has already achieved positive cash flow.

Odaily News: Around 03:30 on July 9, an independent home miner used a handheld Bitaxe device via Public Pool to mine Bitcoin block 957382, securing the full block reward of 3.1382 BTC, including a 3.125 BTC block subsidy and approximately 0.0132 BTC in transaction fees, valued at roughly $200,000 at the time. The device operated at an average hashrate of 995.2 GH/s and submitted the winning share after running for about 8 hours. The Bitaxe is an open-source single-chip Bitcoin miner based on Bitmain's BM1370 chip. The Gamma series has a default hashrate of approximately 1.0 to 1.3 TH/s and a power consumption of 15 to 21 watts, typically priced between $60 and $150. (Bitcoin.com News).

Odaily News U.S. Senator Elizabeth Warren has sent a letter to U.S. Secretary of Commerce Howard Lutnick, requesting documents and communication records related to Bitmain to understand how the Department of Commerce is handling the potential national security risks posed by the company.Bitmain is a leading global manufacturer of Bitcoin mining machines. In November 2024, the U.S. Department of Homeland Security initiated an investigation codenamed "Operation Red Sunset" to examine whether Bitmain's ASIC miners could be remotely accessed for espionage or to disrupt the U.S. power grid. It is reported that the investigation remains ongoing.Previously, shipments of Bitmain equipment were halted, and the use of its miners near U.S. military bases was flagged as posing significant national security risks. Warren's letter also demands that the Department of Commerce provide details of communications between Bitmain, the Trump family, and Department of Commerce officials. The Trump-backed American Bitcoin Corp. had previously purchased 16,000 Bitmain miners for $314 million.

According to Odaily, F2Pool co-founder Wang Chun posted on the X platform in response to recent crypto market cycle fluctuations, stating that Ethereum once fell to $1,386 in April 2025 but rebounded to $4,956 just four months later. He emphasized that the market is cyclical and investors should not be swayed by short-term panic.Previously, Wang Chun also pointed out that the Proof-of-Work (PoW) mechanism is Bitcoin's "constitution," and the mining mechanism and the core role of miners in Bitcoin network governance should be respected. Without miner support, it would have been difficult to activate Segregated Witness (SegWit) and implement the Lightning Network. Miners are a crucial force in maintaining Bitcoin network security and stability, having played key roles in multiple controversial events, including the hashrate competition surrounding Bitmain, Roger Ver's related forking stance, the Satoshi Nakamoto identity controversy sparked by Craig Wright, and the BIP-110 proposal viewed by some in the community as a farce.

According to Odaily Planet Daily, Bitcoin's hashrate dropped 4% in the month ending December 15th, and miner capitulation is historically a bullish contrarian signal. Matt Sigel, Head of Crypto Research at VanEck, and Patrick Bush, Senior Investment Analyst, pointed out that since 2014, the probability of a positive 90-day forward return for Bitcoin when the current hashrate declines over the past 30 days is 65%. Bitcoin is currently trading at $88,400, nearly 30% lower than its all-time high of $126,080 on October 6th. Furthermore, the break-even electricity price for Bitmain S19 XP miners has decreased from $0.12/kWh in December 2024 to $0.077/kWh. Analysts suggest the hashrate decline may be driven by the closure of approximately 1.3 gigawatts of mining capacity in China, with some electricity potentially being diverted to meet AI demands. Currently, 13 countries, including Russia and Japan, still support Bitcoin mining.

According to an announcement from the Hong Kong Stock Exchange, International Commercial Settlement (00147.HK) announced that the buyer, Keen Golden Limited (a 70%-owned joint venture established by the company to conduct cryptocurrency-related businesses), has entered into sales and purchase agreements with the sellers, Bitmain Technologies and Tecnoenergia Capital, for the sale and purchase of cryptocurrency mining hardware and other equipment or commodities, with a total consideration (after tax) of approximately US$10.9 million.

Odaily News Bitzero, a crypto mining company backed by Kevin O'Leary, recently received $25 million in financing, which it plans to use to expand its mining operations. The company said that the first batch of funds will be used to purchase 2,900 Bitmain S21 Pro mining machines, which are expected to be deployed within four to six months, bringing the company approximately $10 million in new revenue each year. At the same time, Bitzero is committed to using hydropower and low-carbon energy to promote the sustainable development of its data centers in North America and Europe. Mohammed Bakhashwain, president and CEO of the company, said that the financing will accelerate the deployment of leading mining technology and further consolidate Bitzero's leading position in sustainable and profitable data centers.

Odaily News In response to the Trump administration's "Liberation Day" tariff increase policy, Bitmain, Canaan and MicroBT, three major Chinese Bitcoin mining machine manufacturers, have set up production lines in the United States, accounting for more than 90% of the global mining machine market. Canaan has already started trial production in the United States, while MicroBT is actively promoting its localization strategy. Analysts warn that China's dominance of hardware supply poses a strategic risk to the United States, and U.S. mining companies are pushing to restrict imports of Chinese products to balance supply and demand.
