Bitcoin’s mining difficulty fell 9.13% at block 975744 on Nov. 14, 2026, from 148.36 trillion to 134.82 trillion. The source calls it the third-largest reduction of 2026 and says 12 of the year’s 23 adjustments had been downward.
The source reports that roughly 100 exahash per second of computing power left the network in the first two weeks of November, while block intervals ran longer than the 10-minute target. It links the decline to falling bitcoin prices and strained mining revenue. As of Nov. 15, the five most profitable mining machines had estimated daily profits of $4.37 to $8.74, assuming electricity costs of $0.10 per kilowatt-hour.
