Bitcoin’s difficulty climbed sharply this week, rising 7.15% and notching the second-largest upward adjustment of the year. Although the network has recorded six increases in 2026, downward adjustments have remained the prevailing theme.
Key Takeaways:
Bitcoin’s difficulty rose 7.15% at block 955,584 on June 26, marking the year’s second-largest increase.Hashprice dropped 18.34% in 30 days to $28.68 per PH/s, squeezing margins for Bitcoin miners network-wide. Hashrate holds near 984 EH/s as miners absorb losses, betting on cyclical recovery and future BTC accumulation.When Satoshi mined the genesis block, the network required a guess beginning with roughly eight leading zeros in hexadecimal to qualify as valid. Today, at a difficulty of 133.87 trillion, a valid hash needs about 22 leading zeros. Each additional leading zero makes the odds exponentially tougher because the target shrinks by a factor of 16 every time.
Bleeding but StandingThat decline has weighed on miner revenue, with hashprice, or the expected value of one petahash per second (PH/s), sitting at $28.68. That figure is 18.34% lower than it was 30 days earlier on May 27, when hashprice stood at $35.12.
