TechFlow news, on June 14, Galaxy Research data shows that Bitcoin completed its latest mining difficulty adjustment at block height 953,568.
This adjustment reduced the mining difficulty from 138.96 T to 124.93 T—a decline of 10.09%, making it the 11th-largest difficulty reduction in Bitcoin’s history and the second-largest single reduction since 2026.
Galaxy Research notes that since early June, BTC’s price has fallen approximately 15%, significantly compressing miners’ profit margins. As a result, some high-cost miners have shut down equipment or temporarily exited the network, driving down the network’s total hash rate.
Due to this hash rate decline, the current difficulty adjustment cycle lasted approximately 15.6 days—noticeably longer than Bitcoin’s target adjustment period of roughly 14 days.
A mining difficulty reduction eases competitive pressure on remaining active miners for block rewards, helping improve their revenue conditions. Historically, large difficulty adjustments typically occur during periods of significant market volatility or markedly deteriorating miner profitability, and are thus considered one of the key indicators for assessing miner operational health and overall network robustness.
