Bitcoin's mining difficulty fell by just 0.03% on October 3, settling at 132.72T. The unusually small adjustment followed a 4.16% increase in the previous epoch and leaves miners competing at nearly the same difficulty level.
Bitcoin's latest difficulty adjustment was notable for what did not happen.
At block 969,696 on October 3, mining difficulty declined by only 0.03%, moving from 132.76T to approximately 132.72T. The adjustment took place at 07:16 UTC. Luminex Mempool
Changes this small are unusual.
Firsthand Bitcoin calculated that the move was the smallest difficulty retarget since June 2020 and the fourth-smallest among 466 adjustments in Bitcoin's history. By comparison, the previous 19 adjustments in 2026 moved by an average of around 4.4%. Firsthand Bitcoin
The flat adjustment also follows a period in which competition had been moving higher.
Difficulty increased 4.16% on September 19 after another 1.31% increase on September 5. Even after the latest marginal decline, current difficulty remains roughly 5.5% above its level one month ago. CoinWarz
Hashrate Remains Close to the Zetahash Range
Mempool.space currently estimates seven-day network hashrate at roughly 950 EH/s. Hashrate estimates vary depending on the measurement window, but the broader picture remains one of substantial computing capacity still competing for Bitcoin's block subsidy. Mempool.space
For miners, a 0.03% difficulty change provides effectively no meaningful relief.
Firsthand estimated that 1 PH/s of mining power earned about 47,767 satoshis per day on October 2, worth roughly $40.54 at the time. A difficulty reduction of only three hundredths of a percent barely changes that equation. Firsthand Bitcoin
Transaction Fees Remain Modest
Across the latest 144 blocks, mempool.space reports average transaction fees of approximately 0.024 BTC per block. The block subsidy therefore continues to represent the overwhelming majority of miner revenue under current network conditions. Luminex Mempool
That keeps Bitcoin price, electricity cost and mining difficulty at the center of the profitability equation.
What Comes Next?
It is far too early to draw a firm conclusion about the next difficulty adjustment.
More than 1,890 blocks remain in the new epoch. Early estimates currently point toward a downward adjustment, but projections at this stage can move sharply as block production speeds up or slows down. ChainQuery.com
For now, the clearest message from the October 3 retarget is that network competition has temporarily reached an unusual balance.
Miners are not receiving meaningful difficulty relief, and operations running older ASICs or higher electricity prices remain particularly sensitive to efficiency, uptime and rejected shares.
