The difficulty of Bitcoin (BTC) mining fell slightly on Saturday after reaching an all-time high of 126.9 trillion on May 31 at the start of the previous difficulty adjustment period.
According to Cryptoquant data, the difficulty of Bitcoin mining is currently at around 126.4 trillion.
Mining difficulty and network hashrate are high. This is another relevant measure of the total computing power protecting the Bitcoin protocol, both leading to increased minor competition and increased production costs.
Miners have changed the calculations of mining companies struggling to maintain profitability as they continue to face financial pressure from declining block rewards, following half of April 2024, following rising operating costs and increasing mining difficulties.

Despite headwinds, some publicly traded mining companies will bounce back to trends and expand their operations
Despite the claims facing miners within the competitive industry, some publicly available Bitcoin mining companies have chosen to expand their operational capabilities and retain mined BTC as financial assets.
Mining company Mara announced that it would increase its BTC output by 35% in May amid record-breaking hashrates and market volatility.
On April 5th, Bitcoin’s network hashrate passed 1 second (Zh/s) per second with computing power. This is an important milestone in decentralized currency protocols.
Despite this, Mara announced in May that it had mined 950 Bitcoin and increased its Corporate Treasury reserves to 49,179 BTC, making it one of the world’s largest Bitcoin holders.
“Mara’s record production month – and then we sold Zero Bitcoin,” the company’s chief financial officer, Salman Khan, wrote in the X-Post on June 3rd.
CleanSpark is a public Bitcoin miner focused on protecting networks through clean energy, increasing BTC production in May 2025.
The company mined 694 BTC that month, increasing 9% with production in April, with total reserves of 12,502 BTC, according to the monthly report.
“We increased our month-end hashrate to 45.6 exahash per second (EH/s), an increase of 7.5%,” CleanSpark president and CEO Zack Bradford wrote in a May update.
The growth trends of mining companies that accumulate Bitcoin as a financial asset represent a major shift in the business strategy of mining companies that traditionally sold coins to cover operational costs.
