Crypto prices moved hard this month. Bitcoin went from about $62,966 to $77,277 in seven days, a rise of 22.7%, after the U.S. Treasury announced a debt buyback and the White House pushed Congress to pass the Clarity Act. Zcash did something even bigger. ZEC climbed from $488.69 to $824.54, a jump of 68.7%, after Grayscale filed to list a Zcash ETF on NYSE Arca.
Headlines stop there. Miners cannot. A higher coin price does not simply mean "more profit for everyone." It sets off a chain of four things: revenue rises, machine demand rises, network difficulty rises, and the gap between cheap electricity and expensive electricity gets much wider. This article walks through that chain in plain language, with the real numbers behind each step.

1. What a price rise actually pays a miner
A Bitcoin miner does not get paid in dollars. It gets paid in bitcoin, and the amount of bitcoin it earns per day barely changes from one week to the next. What changes is what that bitcoin is worth.
The industry has one number for this: hashprice. It is simply how many dollars one petahash per second of mining power earns in a day, before electricity.
On 17 August hashprice was $31.80 per PH/s a day. By 22 August it had reached $38.29 — a rise of 20.4% in four days. That number is not a forecast. It is what the network actually paid out.
Notice something important: Bitcoin rose 22.7% but hashprice rose only 20.4%. The difference is difficulty, which crept up over the same period and quietly took a slice back. More on that in section 4.
2. Not every miner gains the same amount
Here is the part most coverage misses. When hashprice goes up, every miner on earth gets the same extra revenue per unit of hash power. Electricity bills do not change at all. So the rally lands as a flat dollar gain on top of very different starting positions.
The clearest way to see this is revenue per megawatt hour. Modern machines squeeze far more revenue out of the same electricity than old ones do.
Revenue tiers published by Hashrate Index (17 August 2026), scaled to the 22 August hashprice of $38.29. Cost lines are the OneMiners network average of $0.0480/kWh and a typical 12¢ commercial rate.
Read the chart this way. At 12¢ per kWh, a megawatt hour costs $120. Only the newest sub-14 J/TH machines earn more than that, and only by a few dollars. Everything older is losing money at that power price even after a 20% rally. At 4.8¢ per kWh, a megawatt hour costs $48, and every single tier is comfortably profitable.
A rising Bitcoin price does not rescue expensive electricity. It just makes cheap electricity pay more.
3. The break-even power price, machine by machine
There is a short formula every miner should know. It tells you the highest electricity price a machine can pay before it stops making money:
Plug in today's hashprice of $38.29 and an Antminer S23 Hyd at 9.5 J/TH and you get 16.8¢ per kWh. A week ago the same machine broke even at 13.9¢. The rally moved the survival line about three cents higher for every machine on the market.
| Miner | Efficiency | Break-even 17 Aug | Break-even 24 Aug | Works at 4.8¢? | Works at 12¢? |
|---|---|---|---|---|---|
| Antminer S23 Hyd | 9.5 J/TH | 13.9c | 16.8c | Yes | Yes |
| Antminer S21 XP Hyd | 12.0 J/TH | 11.0c | 13.3c | Yes | Yes |
| Antminer S21 XP | 13.5 J/TH | 9.8c | 11.8c | Yes | No |
| Antminer S21 Pro | 15.0 J/TH | 8.8c | 10.6c | Yes | No |
| Antminer S21 | 17.5 J/TH | 7.6c | 9.1c | Yes | No |
| Antminer S19 XP | 21.5 J/TH | 6.2c | 7.4c | Yes | No |
| Antminer S19j Pro | 29.5 J/TH | 4.5c | 5.4c | Yes | No |
| Antminer S19 (95T) | 34.5 J/TH | 3.8c | 4.6c | No | No |
Look at the last two columns. At the OneMiners network average of 4.8¢, everything down to the S19j Pro generation still makes money — hardware that is years old. Only the oldest 34.5 J/TH S19 falls just short, and even that one clears at the 3.64¢ Nigeria rate. At 12¢, only the top three machines on the market survive and the whole S19 generation is underwater. Same rally, same coin price, completely different outcome — decided entirely by the power contract.
4. Why the gain does not last: difficulty catches up
Bitcoin is designed to stay on schedule. Roughly every two weeks it counts how fast blocks were found and adjusts difficulty so blocks keep arriving about every ten minutes. If more machines plug in, difficulty rises, and everyone's share of the daily bitcoin shrinks.
This is the timing that matters:
Right now the Bitcoin network runs at about 922 EH/s with difficulty near 126 trillion. Difficulty is still roughly 14% below its 2026 high, because months of weak revenue pushed high-cost machines off the grid. That leaves clear headroom for it to climb back.
A useful sanity check: if difficulty returned all the way to its 2026 peak while Bitcoin held today's price, hashprice would settle near $33 rather than $38.29. Still better than the $31.80 of a week ago, but well short of the peak. Miners who plan around $38.29 lasting forever tend to be disappointed.
5. A real example: one Antminer S23 Hyd
Take the most efficient air-or-hydro machine widely available today. The Antminer S23 Hyd does 580 TH/s at 5,510 watts, which is 9.5 J/TH. It is listed at $12,299 on OneMiners. It burns 132.2 kWh a day, every day, no matter what the price of Bitcoin does.
At today's hashprice it earns $22.21 a day gross, up from $18.44 a week ago. Here is what is left after the power bill:
| Electricity price | Power cost/day | Profit 17 Aug | Profit 24 Aug | Profit/month | Payback on $12,299 |
|---|---|---|---|---|---|
| 3.64c Nigeria | $4.81 | $13.63 | $17.39 | $529 | 23 months |
| 4.80c OneMiners avg | $6.35 | $12.10 | $15.86 | $482 | 26 months |
| 5.53c USA flagship | $7.31 | $11.13 | $14.90 | $453 | 27 months |
| 7.00c | $9.26 | $9.19 | $12.95 | $394 | 31 months |
| 10.0c | $13.22 | $5.22 | $8.98 | $273 | 45 months |
| 12.0c | $15.87 | $2.58 | $6.34 | $193 | 64 months |
| 18.0c | $23.80 | $-5.36 | $-1.60 | $-48 | never at this price |
The rally handed every one of those rows the same $3.77 a day in extra gross revenue. But look at what that did in percentage terms:
- At 4.8¢, daily profit went from $12.10 to $15.86 — up 31%.
- At 12¢, daily profit went from $2.58 to $6.34 — up 146%.
The high-cost miner posts the bigger percentage, and that is exactly the trap. It is a big percentage of almost nothing. In real dollars the low-cost miner earns two and a half times more per machine, and it stays profitable in every scenario. The expensive setup only works while the rally holds.
6. ROI: what the rally did to payback time
Return on investment in mining is simple arithmetic: hardware cost divided by daily profit. Since the rally moved daily profit, it moved payback too — but not equally.
At 4.8¢ the machine pays for itself inside its warranty period with years of runway to spare. At 12¢ it needs more than five years, which is longer than most ASICs stay competitive. The hardware is identical in both cases. Only the electricity contract is different.
These are scenarios, not promises. They assume today's hashprice holds, and it will not hold exactly. The point is the ratio between the columns, and that ratio holds in every market.
7. Zcash: the same physics, a much sharper move
Zcash is mined with the Equihash algorithm on dedicated machines like the Antminer Z15 Pro, which does 840 kSol/s at 2,780 watts and is listed at $7,499. Zcash is a far smaller network than Bitcoin, so a price move hits revenue much harder and difficulty takes longer to respond.
A week ago that machine was grossing roughly $21.98 a day. Today it grosses about $37.09 a day. That is the ETF news showing up directly in a miner's earnings.
| Electricity price | Power cost/day | Profit a week ago | Profit 24 Aug | Profit/month | Payback on $7,499 |
|---|---|---|---|---|---|
| 3.64c Nigeria | $2.43 | $19.55 | $34.66 | $1,054 | 7.1 months |
| 4.80c OneMiners avg | $3.20 | $18.78 | $33.89 | $1,030 | 7.3 months |
| 7.00c | $4.67 | $17.31 | $32.42 | $986 | 7.6 months |
| 12.0c | $8.01 | $13.98 | $29.08 | $884 | 8.5 months |
Something jumps out immediately. The Z15 Pro is profitable at every power price in the table, even 12¢. Its break-even electricity price right now is around $0.56 per kWh — roughly ten times higher than a Bitcoin machine's. That is what happens when a coin price runs far ahead of its mining difficulty.
This window is real, and it is temporary. Zcash difficulty has been trending steadily upward through 2026, and a payback this short attracts machines fast. As difficulty climbs, gross revenue per machine falls, the break-even line drops back toward Bitcoin territory, and electricity becomes the deciding factor again — just as it already is on Bitcoin. Whoever locked in cheap power before the rush is the one still mining profitably after it.
8. What rallies do to machine prices and availability
The last link in the chain is demand. When mining gets profitable, people buy machines. Manufacturers raise prices, lead times stretch, and the good hosting capacity gets booked. This is a well-worn pattern:
What typically follows a strong price move
- New-generation ASIC prices firm up, and discounts on current stock disappear.
- Delivery windows push out from weeks to months as order books fill.
- Low-cost hosting capacity sells out first, because that is where the margin is.
- Older machines that were switched off get turned back on, pushing difficulty higher.
- Whoever secured hardware and a fixed power rate before the move captures the widest margin.
That is why the current sale pricing matters. The S23 Hyd is listed at $12,299, reduced from $15,000, and the S21 XP Hyd at $6,199, reduced from $8,859. Those are pre-rally prices sitting in a post-rally market.
9. Where OneMiners fits
Everything above reduces to one sentence: the coin price decides what mining pays, and the electricity contract decides how much of it you keep. The first one is out of anyone's hands. The second is a decision.
OneMiners runs 20 hosting sites across roughly 2,163 MW of contracted capacity, at an average all-in rate of $0.0480 per kWh. Rates are fixed on seven-year prepaid energy contracts, so a miner's cost side does not move when the market does.
| Site | Capacity | Rate per kWh | S23 Hyd profit/day at today's hashprice |
|---|---|---|---|
| Nigeria LOWEST | 33 MW | $0.0364 | $17.39 |
| Ethiopia (hydro) | 40 MW | $0.0399 | $16.94 |
| UAE (Dubai & Abu Dhabi) | 34 MW | $0.0420 | $16.66 |
| Finland & Norway Arctic | 58 MW | $0.0448 | $16.29 |
| USA regional (NY, GA, SC, Houston, TX, KS) | 336 MW | $0.0455 | $16.19 |
| Canada | 25 MW | $0.0476 | $15.92 |
| For comparison: a typical 12¢ commercial rate leaves $6.34 a day on the same machine. | |||

Does a higher Bitcoin price always mean higher mining profit?
Not permanently. Revenue rises the same day, but difficulty adjusts roughly every two weeks and takes part of it back. The lasting gain depends on how much of the increase survives the next few difficulty adjustments.
What is hashprice in simple terms?
It is the daily dollar revenue from one petahash per second of mining power, before electricity. Today it is $38.29. It goes up when the coin price goes up and down when difficulty goes up.
How do I know if my miner is profitable?
Use the break-even formula: hashprice divided by (24 × the machine's J/TH). That gives the highest electricity price the machine can pay. If your rate is below it, you are profitable. If it is above, you are not.
Why did Zcash rise so much more than Bitcoin?
Zcash is a much smaller market. Grayscale filing to list a Zcash ETF on NYSE Arca, plus reported institutional buying interest, moved a small market a long way. Small markets move further in both directions.
Is Zcash mining more profitable than Bitcoin mining right now?
Per machine, on paper, yes — because Zcash's price ran far ahead of its difficulty. That gap is the whole reason, and gaps like it close as more machines join. Treat it as a window, not a permanent state.
Should I buy a miner during a rally?
Buying into hype is how people overpay. What matters more than timing is the power price you secure, because that number stays with the machine for its whole life. A cheap contract makes a mediocre entry work; an expensive one ruins a good entry.
What share of mining cost is electricity?
For most operations, 70% to 85% of running cost. On an S23 Hyd at 12¢ per kWh it is currently about 72% of gross revenue. At 4.8¢ it is about 29%.
What happens to my miner if prices fall again?
Break-even lines drop, and the highest-cost machines are the first to switch off. Machines on fixed low-cost power keep running through downturns, which is also when hosting capacity becomes available and hardware gets cheap.
Does difficulty ever fall?
Yes. It falls when machines leave the network. Bitcoin difficulty is currently around 14% below its 2026 high, precisely because months of weak revenue pushed high-cost operations offline.
How much power does an Antminer S23 Hyd use?
5,510 watts, which is 132.2 kWh a day. At $0.0480 per kWh that is $6.35 a day. At 12¢ it is $15.87 a day for exactly the same work.
What is a realistic payback period on a new miner?
At today's hashprice and a 4.8¢ rate, an S23 Hyd pays back in roughly 26 months. At 12¢ the same machine needs over five years. Payback is set far more by the power contract than by the hardware.
Can I mine both Bitcoin and Zcash?
Not with the same machine. Bitcoin uses SHA-256 and Zcash uses Equihash, so each needs its own dedicated hardware. Some operators run both to spread exposure across two different markets.
Price decides what mining pays.
Electricity decides what you
keep.
