Bitcoin mining companies demonstrated strong growth in July 2025, highlighting that computing power expansion and energy optimization strategies have become the core profit-making abilities for mining firms.

In July 2025, the Bitcoin mining industry delivered impressive monthly reports. Mining companies such as Cango, CleanSpark, and Marathon not only increased production capacity but also raised their holdings, injecting new momentum into an industry facing reward halving. Capacity grows against the trend post-halving. According to data released by Cango on August 5, 650.5 bitcoins were mined in July, a 45% increase from June. The current deployed computing power reaches 50 EH/s, and holdings have risen to 4,529.7 bitcoins. CEO Paul Yu pointed out: The newly added 18 EH/s of computing power at the end of June significantly contributed to the increase in output, and we will continue to maintain strong operational efficiency and future growth. Established mining companies are also expanding. According to the monthly report released by CleanSpark, 671 BTC were mined in July, and holdings increased to 12,703 BTC; Marathon continues to maintain the position of the largest publicly listed mining company with a market value of over 6.2 billion USD. The total network hash rate is approximately 899 EH/s, an increase of 4% month-on-month, while mining difficulty has risen by 9%. Cash flow and energy strategies are key to success. According to a report by CoinDesk citing JPMorgan, in July of this year, the average daily profit per EH from Bitcoin mining reached $57,400, a new high post-halving. Mining companies are also enhancing financial flexibility through strategic coin sales: CleanSpark sold 575.97 BTC, raising $64.7 million in cash; Riot sold 475 BTC, injecting $54.8 million. Additionally, CleanSpark adjusted its electricity usage to take advantage of regional heat waves, while Riot reduced costs with a $13.9 million power credit line and reserved land to expand computing power. This indicates that the competition for mining computing power is still ongoing. Mining expands into unfamiliar territories. Facing external variables such as interest rates, inflation, and environmental regulations, mining companies must combine economies of scale with low-cost energy to maintain competitiveness. Third-world countries and nations without a previous mining industry are already entering this consideration. For example, Cango plans to establish mining sites in North America, the Middle East, South America, and East Africa. Smaller unlisted mining companies are also transitioning to large-scale mining under the 'Jamaica policy' of small nations, sharing profits at a national level. This reflects the mining industry moving towards globalization and diversified energy allocation, and of course, AI computing power is also an alternative profit source for the mining industry.
