POOL BTC is an independent comparison site for bitcoin mining pools. We are not a pool and we do not mine for you. This is the first issue of a monthly series. Every number below comes from one data set, and we describe it without guessing at causes. If you want to compare pools themselves, start with the pools list.
September in numbers
| Metric | Value |

| Hashrate, start of month (2026-09-01) | 921.4 EH/s |

| Hashrate, minimum (2026-09-20) | 826.1 EH/s |

| Difficulty, end of month | 132.8 T |
| Adjustment 2026-09-05 | +1.31%, to 127.5 T |
| Adjustment 2026-09-19 | +4.16%, to 132.8 T |

Hashrate
The daily series starts at 921.4 EH/s on 2026-09-01 and ends at 1051.0 EH/s on 2026-09-30. The average for the month is 944.4 EH/s.
The line is not smooth. The daily values move up and down all month. The lowest day is 2026-09-20 at 826.1 EH/s. The highest day is 2026-09-29 at 1088.3 EH/s, one day before the end of the month. The last day, 2026-09-30, is at 1051.0 EH/s.
The first week shows the same pattern. The series goes from 921.4 EH/s on 2026-09-01 to 853.8 EH/s on 2026-09-03, then to 987.3 EH/s on 2026-09-04. On 2026-09-07 it reaches 1040.1 EH/s, and on 2026-09-11 it is at 835.9 EH/s.
So the month ends higher than it started, but the path between the two points is uneven. A single day is a weak guide here. The monthly average of 944.4 EH/s is a calmer way to read the series.
We do not explain these swings. The data set contains daily values only, and it has no information on what moved them.
Difficulty
Difficulty started September at 125.8 T and ended at 132.8 T. There were two adjustments.
| Date | Change | Difficulty after |
|---|---|---|
| 2026-09-05 | +1.31% | 127.5 T |
| 2026-09-19 | +4.16% | 132.8 T |
Both adjustments were increases. The second one is larger than the first. The two dates are 14 days apart.
The net effect for the month is the product of the two changes: 1.0131 multiplied by 1.0416 gives about 1.055, which is +5.5%. This matches the start and end values in the table.
Price
The BTC price opened September at $78,569 and closed at $83,633. That is a change of +6.4% over the month.
The price is a daily snapshot from the historical-price endpoint of mempool.space, so it is one value per day and not an intraday high or low.
We show the price next to hashrate and difficulty only so that all three monthly numbers sit in one place. We do not link them to each other.

FAQ
What is hashrate?
Hashrate is the total computing power that miners put into the Bitcoin network. It is measured in hashes per second. One EH/s is one quintillion hashes per second. In this recap the unit is EH/s.
What is a difficulty adjustment and how often does it happen?
Difficulty is the value that sets how hard it is to find a block. It is adjusted every 2016 blocks, roughly every two weeks. In September 2026 there were two adjustments, on 2026-09-05 and on 2026-09-19. The block heights in our data, 965664 and 967680, are 2016 blocks apart.
Where do the numbers come from?
Hashrate, difficulty and price come from the mempool.space API, fetched on 2026-10-26. The count of 51 materials comes from the publication dates on POOL BTC. We did not add any other figures.
Will there be a monthly issue?
Yes. This is the first issue of a monthly series. Each issue covers one calendar month and uses the same structure: hashrate, difficulty, price, what we published and pool rating changes.
Bottom line
September 2026 in short: average hashrate 944.4 EH/s, two difficulty increases that add up to +5.5%, and a BTC price change of +6.4%. This is information, not investment advice.
