Bitcoin mining company CleanSpark announced that it mined 614 BTC during June 2026. The company’s operational hashrate reached 50 exahashes per second, while its total Bitcoin holdings increased to 13,924 BTC by the end of the month.
Bitcoin miners are back to business as usual after last month’s Arctic blast iced operations across the U.S., and the network’s hashrate has clawed its way back above the 1 zettahash per second (ZH/s) mark. Even so, mining revenue is painfully lean to start March at under $30 per petahash per second (PH/s), and difficulty is projected to climb yet again.
Following the prior difficulty recalibration that occurred 2,016 blocks ago—roughly two weeks back on Feb. 7—the Bitcoin protocol has now delivered a sharp counterpunch. On Thursday, at block height 937440, mining difficulty climbed 14.73%, effectively wiping out the earlier steep reduction and reminding participants that in this arena, gravity is optional and reversals are swift.
While bitcoin just posted its steepest difficulty decline since China’s 2021 mining purge, the network has already found its footing, and the next adjustment cycle is shaping up to be a sizable one, with roughly 34% of blocks still left to be mined before the epoch closes.
This weekend, the Bitcoin network logged its steepest difficulty cut since July 3, 2021—a moment that followed China’s sweeping ban on mining and trading, which triggered a sharp market sell-off and sent miners scrambling for exits beyond the region.
According to the latest data, Bitcoin’s computing firepower has cranked up to a blazing all-time high of 1,157 exahash per second (EH/s). This climb in hashrate hasn’t taken a coffee break, even as prices dip and mining profits feel more like leftovers than a feast.
