According to Cointelegraph, Bitcoin's mining difficulty experienced a slight decrease on Saturday, following its peak at an all-time high of 126.9 trillion on May 31. The current difficulty level stands at approximately 126.4 trillion, as reported by CryptoQuant. This adjustment reflects the ongoing competitive nature of the Bitcoin mining industry, where increased difficulty and network hashrate contribute to heightened competition among miners and elevated production costs. Miners are grappling with financial pressures due to the reduced block reward after the April 2024 halving, alongside rising operational costs and increased mining difficulty. These factors have significantly impacted the profitability calculations for mining companies striving to maintain their operations. Despite these challenges, some publicly traded Bitcoin mining firms are expanding their operational capacity and opting to retain their mined Bitcoin as a treasury asset. Notably, mining firm MARA reported a 35% increase in Bitcoin output in May, amidst record-level hashrate and market volatility. On April 5, Bitcoin's network hashrate surpassed 1 zetahash per second (ZH/s), marking a significant milestone for the decentralized monetary protocol. MARA announced that it mined 950 Bitcoin in May, boosting its corporate treasury reserves to 49,179 BTC, positioning it as one of the largest Bitcoin holders globally. This trend of accumulating Bitcoin as a treasury asset signifies a strategic shift for mining companies that traditionally sold their coins to cover operational expenses. CleanSpark, another public Bitcoin miner focused on clean energy, also reported increased BTC production in May 2025. The company mined 694 BTC during the month, reflecting a 9% increase over April's production, and raised its total reserves to 12,502 BTC, according to its monthly report. CleanSpark's president and CEO, Zack Bradford, highlighted the company's sequential increase in month-end hashrate to 45.6 exahashes per second (EH/s), up 7.5% from the previous month. This growing trend of mining companies accumulating Bitcoin as a treasury asset represents a notable shift in business strategy, as firms adapt to the evolving landscape of the cryptocurrency mining industry.
