Bitcoin mining difficulty falls 10.09%, ranking as the 11th-largest single adjustment on record

June 14 — BlockBeats reports that Galaxy Research tracking data shows the Bitcoin network completed its latest difficulty adjustment at block height 953,568. Difficulty dropped from 138.96T to 124.93T, down 10.09%, making it the 11th-largest one-time adjustment in Bitcoin's history and the second-biggest decline since 2026. The data indicates the adjustment period lasted 15.6 days, well above the protocol's roughly 14-day target. Galaxy Research noted that Bitcoin's price has fallen about 15% in total so far in June, squeezing miner margins and pushing some hashpower offline. The resulting decline in total network hashrate set the stage for the downward difficulty reset. Galaxy Research said the move reflects a familiar stress-transmission pattern during price drawdowns—price weakness leading to hashrate exits, followed by a difficulty reduction—as the network returns toward a dynamic equilibrium.
