Bitcoin (BTC) mining difficulty hit its all-time high on Saturday at its all-time high on May 31, down slightly on Saturday.
According to CryptoQuant, the current Bitcoin mining difficulty level is about 126.4 trillion.
Higher mining difficulty and network hashrate are separate but relevant measures that ensure the overall computing power of the Bitcoin protocol, both translate into increased competition for miners and higher production costs.
Miners continue to face financial pressures for reduced box office rewards after halving in April 2024, rising operating costs and increasing mining difficulties, which has changed the calculus that mining companies strive to stay profitable.

Despite the challenges faced by competitive industries, some publicly traded Bitcoin mining companies are still expanding their operating capabilities and opting to keep the BTC they mined as fiscal assets.
Mining company Mara announced it increased BTC output by 35% in May amid record hashrates and market volatility.
On April 5, Bitcoin’s network Hashrate crossed 1 Zetahash per second (ZH/s) in computing power, an important milestone in the decentralized currency protocol.
Still, Mara announced that it mined 950 bitcoins in May and raised its corporate Treasury reserves to 49,179 BTC, making it one of the world’s largest bitcoin holders.
“We sold zero bitcoins for Mara’s record production month,” Salman Khan, the company’s chief financial officer, wrote in a June 3 x post.
Public Bitcoin miner CleanSpark is committed to ensuring network security through clean energy, and he increased his BTC production in May 2025.
According to its monthly report, the company mined 694 BTC this month, with production rising 9% in April, and its total reserves reached 12,502 BTC.
“We’re increasing the end of the month to 45.6 Exahashes (EH/s) per second, a 7.5% increase in succession,” CleanSpark President and CEO Zack Bradford wrote in a May update.
The growth trend of mining companies accumulating Bitcoin as a treasury asset also represents a significant shift in the business strategy of mining companies that have traditionally sold their coins to cover operating costs.
