Bitcoin difficulty is down 18.5% from its peak: what the August 2026 retargets mean for miner payouts
Bitcoin network difficulty just posted its deepest drawdown from a peak since China banned mining back in 2021, down roughly 18.5%. Galaxy Research put out that number on August 10, 2026, and Cointelegraph picked it up. For anyone actually running rigs, that is not a headline stat to skim past. It is the difference between coins landing in your wallet or not, and it is a good reason to check whether your current pool and payout scheme still make sense.
POOL BTC tracks pool fees, cashout cards, and profitability calculators across the market rather than running a pool itself, so this is a good moment to walk through what is actually happening with difficulty right now and what to do about it, instead of just repeating the headline.
Why this drawdown gets compared to the 2021 China ban
The 2021 ban was a single, sudden shock. China cut off mining within its borders almost overnight, hardware went dark, and it took months for that capacity to physically relocate and come back online elsewhere. Difficulty cratered in one sharp move.
2026 looks different under the hood. This is not one event, it is a slow bleed that has been building for months: hashrate has been drifting lower as hashprice stays low and part of the capacity that public mining companies used to point at Bitcoin gets redirected toward AI compute, where margins are currently better. According to Galaxy Research, it is the cumulative weight of that grind, not a single shock, that has produced a drawdown as deep as the one triggered by an outright ban five years ago.
That distinction matters for anyone trying to guess what comes next. After the 2021 shock, hashrate bounced back fairly quickly once relocated hardware found cheap power again. A slow-motion decline does not carry the same promise of a fast reversal. As long as hashprice stays weak and AI compute keeps paying better, there is not much pulling idle ASICs back onto the network.
The August 8 retarget: the first increase after nine straight drops
On August 8, 2026, difficulty rose from 126.23T to 127.48T, up 0.99%. On its own that reads like a routine adjustment. In context it is not: the nine epochs before it all came in negative. The August 8 retarget was the first positive move after a long run of near-continuous declines.
One green retarget does not flip a trend. What it does say is that blocks over the prior two weeks landed a bit faster than the ten-minute target, which means some previously idled hashrate came back online, or new capacity joined the network. The broader shape of the year is still pointed down, and a single increase after nine drops does not undo that math.
The next adjustment is due on August 22, 2026. CoinWarz currently estimates it will land around 128.55T, another 0.84% higher. If that holds, it would be a second straight increase, which starts to look less like noise and more like stabilization.
| Retarget date | Change | Difficulty |
|---|---|---|
| August 8, 2026 retarget | +0.99% | 126.23T to 127.48T |
| August 22, 2026 forecast (CoinWarz estimate) | +0.84% (estimate) | roughly 128.55T |
What this means for miner revenue right now
Difficulty and payout move in opposite directions: at the same BTC price and the same hashrate on your side, lower difficulty means more coins per day on average. That nine-drop streak earlier in 2026 favored anyone who kept their rigs running through it, since their share of found blocks grew every time a competitor throttled down or shifted capacity elsewhere.
A reversal works the same way in the other direction. Every positive retarget shaves a little off each remaining miner's share of new blocks if network hashrate keeps recovering. With BTC trading around $64,900 as of August 9, 2026, margins for a lot of operators are already thin, so even a fraction-of-a-percent difficulty increase is worth pricing in ahead of time rather than after the fact.
Hashprice, the revenue earned per unit of hashing power per day, is worth a separate note. As of an early-August 2026 snapshot (dated August 3), spot hashprice sat around $32.10 per PH/s per day, with a 30-day average around $31.54. Luxor's forward market for the next six months was pricing hashprice at roughly $30.83. That is a snapshot from the start of the month, not a live number: hashprice moves with both difficulty and BTC price, and it will likely have shifted by the time you read this. Treat it as a reference point for the scale of the market, not a figure to plug in without checking a live source.
How retargets shape pool choice: PPS vs. PPLNS in a volatile stretch
The payout scheme a pool runs decides who actually absorbs the swings in luck and difficulty, the miner or the pool. That distinction gets sharper in a period like this one, when difficulty is moving in visible steps.
PPS and its close relative FPPS pay a fixed amount per accepted share, calculated off current network difficulty. When difficulty rises after a stretch of drops, as it just did, a PPS or FPPS pool recalculates the per-share rate almost immediately, so payout changes show up fast and predictably, with no retroactive surprises. Pools charge more for that predictability, since they are the ones carrying the risk of an unlucky stretch without a found block.
PPLNS pays out only when the pool actually finds a block, splitting the reward among miners who submitted shares within the last N window. During a run of rising difficulty, the effect on PPLNS blends into the pool's ordinary luck variance: if the pool gets lucky and finds blocks quickly, a difficulty bump barely registers over a short window. If the pool gets unlucky, the two effects stack, and the revenue dip can feel bigger than the 0.99% or 0.84% the retarget itself accounts for.
A full side-by-side of how the two schemes calculate payouts is in a separate piece on FPPS vs. PPLNS. If you are on a PPLNS pool right now and are not comfortable with sharper swings while retargets keep landing, it is worth running the numbers on what FPPS would look like at your current hashrate before making a call either way.
Using a profitability calculator through swings in difficulty
A one-off profitability calculation done at the start of the year would already be stale a couple of retargets into 2026. Nine straight difficulty drops followed by two straight increases can put a real gap between the best-case and worst-case number for the same ASIC, even before BTC price moves at all.
The practical move is to rerun the numbers in the POOL BTC profitability calculator after every major retarget, not once a month. The calculator pulls current network difficulty and lets you plug in your own power rate and your pool's fee, so you get an actual net BTC and fiat figure rather than a headline number averaged across the whole market.
For a longer view of where difficulty has been trending, the difficulty tracking page on POOL BTC is worth a look, and for comparing how efficient different ASIC models actually are in joules per terahash, the miner ranking is the faster way to check: hardware efficiency is what decides whose margin goes negative first when difficulty climbs.
A short checklist for a stretch of volatile retargets:
- Rerun the calculator after each retarget instead of on a monthly schedule.
- Compare your pool's PPS/FPPS fee against its PPLNS fee if you have not already, since the gap between the two matters more while difficulty is climbing.
- Check your ASIC's efficiency in joules per terahash. If it is noticeably worse than current models, a couple of percentage points of added difficulty can be the number that decides whether your setup stays profitable.
- Do not act on a single retarget. Look at a run of at least two or three in a row, the same way Galaxy Research looked at the full-year trend before calling it the deepest drawdown since 2021.
Where difficulty could go from here
If the CoinWarz estimate for August 22 holds and difficulty climbs another 0.84%, that would be two straight increases after a nine-drop streak, and the case for a genuine trend reversal gets stronger. Even so, the drawdown from the peak stays deep. An 18.5% drop from a peak does not unwind in a couple of positive retargets.
The bigger thing to watch is not difficulty by itself but hashprice, and where public mining companies decide to point their capacity next: back at the Bitcoin network, or further into AI compute. As long as AI compute keeps paying better margins than Bitcoin mining at current hashprice, the network has little pull toward its old difficulty highs.
FAQ
Why is the 2026 difficulty drawdown compared to the 2021 China mining ban?
Because by depth from peak, it is the largest difficulty drawdown since 2021, according to Galaxy Research's August 10, 2026 estimate. The mechanics differ though: 2021 was a sudden shock from a nationwide ban, while 2026 is the result of a gradual, multi-month hashrate decline.
Does the August 8 increase mean the drawdown is over?
One positive retarget after nine straight drops is a signal, not proof of a reversal. Watch the following adjustments, including the one expected on August 22, 2026.
How does a difficulty increase hit payouts on FPPS?
On FPPS, the per-share rate recalculates against current network difficulty almost immediately after a retarget, so the payout change shows up fast, without the lag tied to luck-dependent schemes like PPLNS.
Should I shut down hardware when difficulty rises?
That depends on your ASIC's efficiency, your power rate, and your pool's fee. Rerun profitability with current difficulty and hashprice numbers before deciding anything, rather than working off figures from a month ago.
Where can I find current hashprice if the numbers in this article are already stale?
Hashprice moves with both network difficulty and BTC price, so check a live hashprice tracker and rerun the POOL BTC calculator for the current date instead of relying on a specific day's snapshot from a news article.
