Hashprice Just Jumped 20% in Four Days: Inside Bitcoin Mining’s Best Week Since 2024
For most of 2026, Bitcoin mining has been a grinding business. Hashprice — the single number that tells you what a unit of computing power actually earns — set a record daily low of $27.74 per PH/s per day on 6 June, then spent the summer crawling sideways in the low thirties. Difficulty kept climbing. Margins kept thinning. Analysts kept using the word "capitulation."
Then came the week of 18 August.
In four days, hashprice went from $31.80 to $38.29 per PH/s per day — a 20.41% move and a four‑month high, according to News.Bitcoin.com. Nobody upgraded a fleet. Nobody unplugged a facility. The machines that were quietly losing money on Monday were quietly making money by Saturday, and the only thing that changed was the price of what they produce.
This is the article we would want to read on a Tuesday morning after a week like that: what actually moved, what it does to real hardware at real electricity rates, and which machines flipped from red to green. Every figure below is built on one stated basis — hashprice $38.29, BTC $79,111, network hashrate 922 EH/s — and every machine is a real unit from the live OneMiners catalogue, at its live wattage and its live price. No rounded-off marketing specs.
The four‑day version
- Hashprice: $31.80 → $38.29 per PH/s/day between 18 and 22 August — up 20.41%, a four‑month high.
- Bitcoin closed the week up 22%, its strongest week since 2024, from roughly $62,800 to the high‑$70,000s.
- Network hashrate held near 922 EH/s — within touching distance of one zettahash. Miners did not capitulate.
- Three of the eight machines we modelled flipped from a daily loss to a daily profit at a $0.10/kWh industrial rate.
- At $0.0364/kWh, all eight were already profitable — before the jump. That is the whole argument for cheap contracted power in one line.
1. The week in numbers
Start with the receipts. These are the published weekly prints, not estimates.
| Metric | Week before (17–18 Aug) | Week of the move (22–25 Aug) | Change |
|---|---|---|---|
| USD hashprice | $31.80 | $38.29 | +20.41% |
| Bitcoin price | $64,259 | $79,111 | +23.1% |
| Network hashrate (7‑day SMA) | 920 EH/s | ~922 EH/s | +0.2% |
| Network difficulty | 127.48T | 127.48T → retarget | flat, then easing |
| Transaction fees, share of block reward | 0.69% | 0.75% | still a rounding error |
| Average block time | 10 min 00 s | 10 min 05 s | slightly slow |
Sources: Hashrate Index Roundup (17 Aug 2026) for the weekly prints; News.Bitcoin.com (23 Aug 2026) for the 18–22 August hashprice move and block time; Fortune (25 Aug 2026) for spot BTC.
The shape of 2026 in five bars. Note the last one: the forward market was pricing $30.67 for the next six months as of 17 August. The spot move outran the forward curve, which is exactly why it caught so many operators mid‑shrug.
Hashprice is the mining industry’s wage. It is not a price you negotiate, it is a price you receive — and the only half of the equation you control is what you pay for power.
2. Why it happened (spoiler: not the miners)
Hashprice has two inputs. Total network reward — block subsidy plus fees, priced in dollars — on top, and total network hashrate on the bottom. Miners had nothing to do with last week. The top half moved.
Bitcoin closed Friday 21 August up 22% for the week, its strongest weekly run since 2024, climbing from roughly $62,800 at the start of the week. Four things were pushing at once:
A softer dollar
A weaker US dollar mechanically lifts crypto for every non‑US buyer. Nothing clever about it — it is arithmetic on the denominator.
ETF inflows with a name on them
$606Mentered US spot Bitcoin ETFs on Thursday, the largest daily haul since May. BlackRock took 83% of it — institutional, not retail.
Washington warming up
The administration pushed for a workable Clarity Act, and the CFTC signalled it would write its own rules if the legislation stalled. Regulatory fog lifting is itself a catalyst.
Treasury buybacks
The Treasury moving to buy back bonds at the long end of the curve loosened liquidity, and liquidity finds risk assets.
Bitcoin’s week. Hashprice is downstream of this line, which is why an operator who cannot control the price of Bitcoin spends their energy controlling the price of electricity instead.
For a plain‑language walk through how difficulty, halvings and hashrate economics fit together, btcfq.com is the reference we point people at.
3. What hashprice actually is, in one paragraph
Hashprice is the daily revenue that one petahash per second of mining power earns. That is it. It bundles the block subsidy, transaction fees, the Bitcoin price and the total network hashrate into a single figure so you can compare a machine bought in 2021 with one shipping in 2027. If a machine does 500 TH/s — half a petahash — then at today’s $38.29 it grosses about $19.14 a day, before it has paid for a single kilowatt‑hour.
The whole model, on one line
- Daily revenue = (TH/s ÷ 1,000) × hashprice. So 500 TH/s × $38.29 = $19.14/day.
- Daily power cost = (watts ÷ 1,000) × 24 × your $/kWh.
- Daily profit = revenue − power cost. There is no third term. That is the entire business.
- Fees are currently 0.69% of block rewards. Real, but not a strategy.
Two things follow from that arithmetic, and they are the two things this whole article is about. Revenue is set by a market you do not control. Cost is set by a contract you do. When hashprice jumps 20%, every operator gets the same 20% on the revenue line — but the operator paying $0.0364/kWh keeps a far larger share of it than the operator paying $0.14.

4. Eight real machines, at today’s numbers
Below are eight units from the live OneMiners catalogue, spanning 9.45 J/TH flagships down to a 23 J/TH veteran. Wattages and prices are the live listed figures, not launch‑spec marketing numbers — which matters, because the two drift apart fast.

Specifications and prices pulled from the live OneMiners catalogue on 25 August 2026. Gross revenue is before electricity. Gold rows are sub‑10 J/TH.
The flagship Antminer S23 Hyd 3U grosses $44.42 a day at the new hashprice — up $7.53 from the Monday. The little Antminer S19k Pro grosses $4.21. Both of those are true, and neither of them tells you anything useful yet, because we have not paid the power bill.
5. The flip list: who went from red to green
Here is the part that matters. Same eight machines, four electricity rates, and the before‑and‑after of a 20% hashprice move. The first two rates are real contracted OneMiners rates. The third is a typical industrial tariff. The fourth is what a lot of people actually pay at home.
| Miner | @ $0.0364 OneMiners Nigeria |
@ $0.0455 OneMiners USA |
@ $0.10 typical industrial |
@ $0.14 high-cost residential |

Daily profit = (TH/s ÷ 1,000 × hashprice) − (kW × 24 × $/kWh). Cross‑check: this basis puts the S23 Hyd 3U at $17.97/day at $0.10/kWh; News.Bitcoin.com published $17.86 for the same machine on 23 August — a 0.6% difference. The Sealminer A4 Ultra Hyd lands at $13.83 against their $13.75. The model reconciles.
Machines that crossed from loss to profit in four days
- Antminer S23 Hyd 3U at $0.1400/kWh (-$0.14 → $7.39 per day)
- Antminer S23 Hyd at $0.1400/kWh (-$0.07 → $3.69 per day)
- Whatsminer M73S at $0.1000/kWh (-$0.34 → $3.30 per day)
- Antminer S21+ Hyd at $0.1000/kWh (-$1.66 → $0.90 per day)
Grey is the Monday, gold is the Saturday. Watch the M73S and the S21+ Hyd cross the zero line, and watch the S21 and S19k Pro fail to. A 20% revenue bump rescues a mid‑tier machine on an industrial tariff. It does not rescue a 17–23 J/TH machine on one.
Read that chart twice, because it contains the only genuinely hard lesson of the week. A hashprice rally is not a fleet strategy. It lifted the machines that were already close to the line. The two least efficient units on the list stayed underwater at $0.10/kWh even after a 20% revenue increase — and they would need hashprice near $42 and $55 per PH/s/day respectively just to break even there. That is not a market you wait for. That is a power contract you change.
6. The one number that decided everything: your electricity rate
Every operator on earth got the same 20% last week. What they kept differed enormously, because electricity is 75–85% of mining operating expense. Here is the same machine — the Antminer S21+ Hyd, 395 TH/s at 5,925 W, a genuinely mainstream unit — at every rate.
| Electricity rate | $/kWh | Power cost/day | Power as % of revenue | Profit/day @ $31.80 | Profit/day @ $38.29 | Profit/month |
|---|---|---|---|---|---|---|
| OneMiners Nigeria (7‑yr fixed) | $0.0364 | $5.18 | 34% | $7.38 | $9.95 | $298 |
| OneMiners Ethiopia (hydro) | $0.0399 | $5.67 | 38% | $6.89 | $9.45 | $284 |
| OneMiners USA regional (7‑yr fixed) | $0.0455 | $6.47 | 43% | $6.09 | $8.65 | $260 |
| OneMiners network average | $0.0480 | $6.83 | 45% | $5.74 | $8.30 | $249 |
| Typical industrial tariff | $0.1000 | $14.22 | 94% | -$1.66 | $0.90 | $27 |
| High‑cost residential | $0.1400 | $19.91 | 132% | -$7.35 | -$4.78 | -$144 |
One machine. One week. The spread between the top row and the bottom row is $442 a month on identical hardware doing identical work. The hashprice rally was worth $77 a month to this machine. The power contract is worth roughly 5.7 times more than the rally was.
The gold bars are all the same 20% better than the grey ones. But the slope from left to right is steeper than the gap between grey and gold at any single rate. Cheap contracted power beats a good week.
Hashrate Index publishes the same truth from the other direction. Sorted by fleet efficiency, revenue per megawatt‑hour ran $107 per MWh for sub‑14 J/TH fleets against $41 per MWh for the least efficient — a 2.6× spread inside the same network, on the same day, at the same hashprice. CoinShares put 15–20% of the global fleet at a loss earlier this year, and pinned the survival line for S19‑class hardware at sub‑$0.05/kWh. Last week moved the line. It did not move it far enough to save a $0.14/kWh S19.
Efficiency and electricity rate are the only two levers in this business. Everything else is noise with a press release attached.
7. Break‑even: how many months, honestly
Payback is where a 20% revenue move stops being an abstraction. Same eight machines, same live prices, 30‑day months, at three rates. Where a cell says never, the machine loses money every day at that rate and no amount of patience fixes it.
| Miner | Gross/day | @ $0.0364 | @ $0.0455 | @ $0.10 |
|---|---|---|---|---|
| Antminer S23 Hyd 3U$28,399 · 9.50 J/TH
|

| Antminer S19k Pro$297 · 23.00 J/TH
|
$4.21 | 4.9 mo | 6.8 mo | never |
Hardware cost ÷ monthly net profit, at the stated hashprice and 30‑day months. Assumes hashprice holds, which it will not — see section 10.
The result that surprised us: the cheapest machine on the list has the fastest payback. The Antminer S19k Pro at $297 recovers its cost in 4.9 months at $0.0364/kWh — and never at $0.10. That is the entire thesis of contracted power stated as one row of a table. Cheap old hardware is not a bad asset. Cheap old hardware on expensive electricity is.
Every bar here is a machine that pays for itself inside five years on a OneMiners rate. Most of them do it inside two. Swap the rate to $0.10 and half of these bars disappear entirely.
8. Where OneMiners fits in this picture
Everything above points one direction: the operators who kept the most of last week’s 20% were the ones who had already fixed their power cost. That is the whole product. OneMiners runs a hosting network of 20 sites and roughly 2,163 MW of contracted capacity, at an average of $0.0480/kWh, with the headline rate at each site fixed on a seven‑year prepaid energy contract.
| Site | Capacity | 7‑yr fixed $/kWh | Notes |
|---|---|---|---|
| Nigeria | 33 MW | $0.0364 | Cheapest active rate; +250 MW expansion underway |
| Ethiopia | 40 MW | $0.0399 | Hydro / renewable power |
| UAE — Dubai & Abu Dhabi | 34 MW | $0.0420 | Premium site, advanced cooling |
| USA regional — New York | 100 MW | $0.0455 | No install fees, no hidden fees |
| USA regional — South Carolina | 68 MW | $0.0455 | No install fees, no hidden fees |
| USA regional — Texas (multi‑city) | 65 MW | $0.0455 | No install fees, no hidden fees |
| USA regional — Houston | 45 MW | $0.0455 | No install fees, no hidden fees |
| USA regional — Georgia | 34 MW | $0.0455 | 3.06 EH/s hosted, 98%+ observed uptime |
| USA regional — Kansas | 24 MW | $0.0455 | No install fees, no hidden fees |
| USA flagship | 336 MW | $0.0553 | Industrial scale, no installation fees |
| China dedicated | 288 MW | $0.0462 | Industrial-scale dedicated capacity |
| Norway (Arctic) | 36 MW | $0.0448 | Arctic natural cooling |
| Finland | 22 MW | $0.0448 | Cold-climate cooling |
| Canada | 25 MW | $0.0476 | Stable North American jurisdiction |

Two footnotes for specific situations. If you are set on running hardware at home and the problem is the noise — an air‑cooled unit is genuinely 75 dB of angry — pcpraha.cz builds the MinerBox acoustic enclosure that brings it down to the 35–45 dB range. If you are deploying 50 units or more under your own brand, Circlehash.com handles the enterprise and white‑label side.
And if you are buying in Europe: IceRiver.eu covers European hardware distribution including Kaspa miners, and Kentino.com has been a multi‑language European retailer since 2014, which is the friendlier door for a first purchase.
9. Who is actually finding the blocks
A fun aside, because the pool table is one of the more legible things in Bitcoin. There are 133 pools of various sizes competing for those blocks. The top five carry most of the 922 EH/s.
| Pool | Hashrate | Share of network | Implied revenue/day @ $38.29 |
|---|---|---|---|
| Foundry USA | 214.73 EH/s | 23.3% | $8.22M |
| Antpool | 156.17 EH/s | 16.9% | $5.98M |
| F2Pool | 110.62 EH/s | 12.0% | $4.24M |
| ViaBTC | 91.02 EH/s | 9.9% | $3.49M |
| Secpool | 65.07 EH/s | 7.1% | $2.49M |
| Spiderpool | 65.07 EH/s | 7.1% | $2.49M |
| Everyone else (127 pools) | ~219.32 EH/s | 23.8% | $8.40M |
Pool hashrate from News.Bitcoin.com, 23 August 2026. Implied revenue is hashrate × hashprice — a useful sanity check, not an accounting figure.
The listed miners had a good week too, which is the market voting on the same arithmetic: BTBT closed up 23.1%, DMGI up 22.0% and HIVE up 18.1% in the run‑up. August mining revenue across the network reached $682.69 million with $5.14 million of that from transaction fees — against $875 million in July, which tells you how thin the first three weeks of the month really were before the turn.
10. What happens next (the honest section)
We are not going to pretend a four‑day print is a trend. Three things are worth watching, and two of them cut against the good news.
Put plainly: the rally is real, it is welcome, and it is not a plan. If your fleet only works when hashprice is above $38, your fleet does not work. The machines in the tables above that stayed green at every rate and both hashprices are the ones built on a foundation that survives the next bad month — low J/TH hardware on a fixed cheap contract.

11. Frequently asked questions
1. What is hashprice, in plain English?
It is the daily revenue that one petahash per second of mining power earns, bundling the block subsidy, transaction fees, the Bitcoin price and total network hashrate into one number. On 22 August 2026 it was $38.29 per PH/s per day. A 500 TH/s machine is half a petahash, so it grossed about $19.15 that day before electricity.
2. Why did hashprice jump 20% in four days?
Because Bitcoin did. BTC closed the week of 21 August up 22%, its strongest week since 2024, driven by a weaker dollar, $606 million of spot‑ETF inflows on the Thursday, a friendlier regulatory tone from Washington and Treasury bond buybacks loosening liquidity. Hashprice is downstream of the Bitcoin price, so it followed.
3. Does a hashprice rally mean my old miner is profitable again?
Only if it was already close to the line. In our modelling three of eight machines flipped from a daily loss to a daily profit at $0.10/kWh — but the Antminer S21 at 17.5 J/TH and the S19k Pro at 23 J/TH stayed underwater at that rate even after the 20% move. Efficiency and electricity rate decide it, not the weekly print.
4. What is the single most important number in mining profitability?
Your electricity rate. Electricity is 75–85% of operating expense. In our six‑rate table, the same Antminer S21+ Hyd earned a spread of hundreds of dollars a month between $0.0364/kWh and $0.14/kWh — several times larger than the entire benefit of the hashprice rally.
5. What electricity rate do I need to mine profitably in 2026?
It depends on the machine. Sub‑10 J/TH flagships were profitable at every rate we modelled including $0.14/kWh once hashprice hit $38.29. Mid‑tier 13–15 J/TH units needed roughly $0.10/kWh or better. S19‑class hardware needs sub‑$0.05/kWh, which matches CoinShares' finding earlier in 2026.
6. How much does OneMiners charge for electricity?
The seven‑year fixed prepaid rate ranges from $0.0364/kWh in Nigeria and $0.0399/kWh in Ethiopia to $0.0665/kWh in Czechia, with the USA regional sites at $0.0455/kWh. The network average is $0.0480/kWh across 20 sites and roughly 2,163 MW of contracted capacity. Confirm the live figure for your site at oneminers.com.
7. Is hosting actually cheaper than mining at home?
On the power line, almost always. A residential tariff around $0.14/kWh put four of our eight machines at or below break‑even even at the higher hashprice. A $0.0364/kWh contracted rate had all eight profitable at both hashprices. Add cooling, noise, uptime and repair and the gap widens further.
8. What is included in OneMiners hosting?
All‑inclusive electricity on the seven‑year fixed contract, a seven‑year hardware warranty, 0% management fees, 98%+ observed uptime against a 95% financially‑compensated guarantee, full installation and maintenance, on‑site repair with continental hubs, AI Smart Mining, app‑based remote control, and free relocation between facilities.
9. What is AI Smart Mining and does it really add revenue?
It is automated optimisation of how machines are run against live conditions — tuning, curtailment response and uptime recovery. Across the OneMiners network it has added between 6% and 115% to revenue depending on the machine and the conditions it was running in. The range is wide because the conditions vary that much.
10. Can I buy a miner without paying the full amount up front?
Yes. OneMiners runs Buy Now Pay Later at 25% down plus three instalments. It does not change the profitability arithmetic in this article — it changes when you pay for the hardware, not what the hardware earns.
11. Which machine had the fastest payback in your modelling?
The cheapest one, which surprised us too. The Antminer S19k Pro at $297 recovered its cost in under six months at $0.0364/kWh. At $0.10/kWh it never recovers, because it loses money every day. Same machine, opposite outcome, decided entirely by the power contract.
12. Why do live catalogue specs differ from launch specs?
Because manufacturers ship revisions and bins. The Antminer S23 Hyd is listed at 580 TH/s and 5,510 W on the live catalogue where older reference tables still carry 380 TH/s. Always model on the wattage and hashrate of the unit actually being sold to you, which is what we did throughout this article.
13. What is the network hashrate now and does it matter to me?
Around 922 EH/s, closing on one zettahash. It matters directly: your share of the fixed 450 BTC per day is your hashrate divided by the network's. As total hashrate grows, every individual slice shrinks. That is a permanent headwind that only better efficiency and cheaper power offset.
14. How much of mining revenue comes from transaction fees?
Very little right now — 0.69% of block rewards in the week of 17 August. Across August, $5.14 million of $682.69 million total mining revenue. Fees spike during congestion and are a real bonus when they do, but no sane model treats them as base revenue.
15. Will difficulty rise and eat this gain?
Probably, at least partly. Difficulty sat at 127.48T with block times running slightly slow, so the immediate retarget pointed to a small easing. But a sustained hashprice at these levels brings idled machines back online, and that raises difficulty, which lowers hashprice. The network has always absorbed gains this way.
16. What does the forward market expect?
Less than spot. Hashrate forwards were pricing $30.67 per PH/s/day for the following six months as of 17 August — below both the $31.80 Monday print and the $38.29 Saturday print. The people who trade hashrate for a living were not betting on the rally holding.
17. How should I model profitability so I do not fool myself?
Use a stated basis and show it, as we did here. Then stress it: model at 70–80% of spot Bitcoin, assume difficulty rises, and check whether the machine still clears its power cost. If it only works at the top of the range, it does not work. Run the live figures at asicprofit.com.
18. Is hydro cooling worth the extra cost?
For high‑density units, generally yes — the sub‑10 J/TH machines in our table are hydro, and efficiency is what kept them green at every rate. For a home setting the honest answer is that hydro adds plumbing complexity you may not want, and if noise is your actual problem, an acoustic enclosure from pcpraha.cz solves that more cheaply.
19. Where can I buy mining hardware in Europe?
IceRiver.eu handles European distribution including Kaspa hardware, and Kentino.com has been a multi‑language European retailer since 2014 and is the gentler starting point for a first purchase. For hosted deployment, OneMiners runs European capacity in Norway, Finland and Czechia.
20. I want to deploy 50 or more units under my own brand. Who do I talk to?
Circlehash.com handles enterprise and white‑label deployments on the same underlying hosting infrastructure. For anything below that, the standard OneMiners hosting contract is the simpler route.
12. The verdict
Last week was a genuinely good week, and it is worth enjoying. It was also a stress test that published its own results. A 20% revenue increase — a large move by any standard — was not enough to rescue a 17 J/TH machine on a $0.10/kWh tariff. It was more than enough to make a 9.5 J/TH machine on a $0.0364/kWh contract look extremely comfortable. The gap between those two outcomes is not the market. It is the decisions taken before the market moved.
If you already mine on cheap contracted power
You just got a raise and you keep most of it. Consider whether the payback figures in section 7 justify adding capacity while hashprice is above the forward curve.
If you mine at home above $0.10/kWh
Check your specific machine against the flip list. If it is still red at your rate after a 20% rally, the machine is not the problem and waiting is not the fix.
If you are buying your first miner
Buy the efficiency, then buy the rate. A cheaper machine on a $0.0364/kWh contract beat an expensive machine on a residential tariff in every table above.
If you are scaling past 50 units
The 7‑year fixed contract is the whole asset. Lock the rate, lock the warranty, and let difficulty do what difficulty does.
The rally gave everyone the same 20%. What you kept was decided by your power contract.
Mining profitability figures in this article are estimates calculated on a single stated basis: USD hashprice $38.29 per PH/s per day (22 August 2026), Bitcoin at $79,111 (25 August 2026), network hashrate 922 EH/s and 30‑day months. Hardware wattages and prices are the live OneMiners catalogue figures on 25 August 2026. Hashprice, difficulty, electricity rates and hardware prices all change — hashprice alone moved 20.41% in the four days this article describes. Past performance does not guarantee future results, and nothing here is investment advice.
