Bitcoin mining difficulty dropped 1.31 percent at block height 963648, marking the 17th adjustment in 2026. The network has recorded ten downward adjustments against just seven increases since January 8, a pattern that underscores sustained miner capitulation.
Difficulty now sits at 125.81 trillion—15.1 percent below the 148.25 trillion level at the year's start and just 0.7 percent above the 2026 low of 124.93 trillion set on June 13. The recovery attempts that followed June have been wiped out: difficulty climbed to 133.87 trillion, then fell to 127.17 trillion, dipped to 126.23 trillion, bounced to 127.48 trillion, and has now retreated to current levels.
The preceding adjustment at block 961632 registered only a 0.99 percent gain before today's 1.31 percent decline negated it entirely. Approximately 150 exahash per second of mining power has disappeared from the network, with hashrate well below its all-time high.
Mining economics deteriorated sharply as Bitcoin fell more than 50 percent below its October 2025 all-time high of $126,000. Recently, conditions have improved: BTC is now 38.8 percent below that peak, lifting hashprice enough to make some previously unprofitable machines viable again. The easier difficulty rating provides additional temporary relief.
But the string of reversals suggests this is a reprieve, not a sustained turnaround. The 150 EH/s of sidelined hashpower represents a significant supply that could flood back online if Bitcoin holds its gains. That influx would quickly eliminate the difficulty discount miners now enjoy, and with BTC still 38.8 percent below its all-time high, mining margins remain exposed to price swings.
