Can You Still Make Money Mining Bitcoin After the Halving? 2026 Real-World ROI
After the April 2024 halving, the block subsidy dropped to 3.125 BTC and every miner’s “daily yield” instantly halved. Everyone knew it was coming, but when it actually landed — compounded by BTC sliding from 110K in late 2025 to 75K by mid-2026 — the entire mining ROI model got rewritten. Small farms that printed money in 2024 began burning cash by 2026, while miners who picked the right rig at the right power price compressed their payback period to under 14 months. This piece runs the May 2026 numbers (S21 Pro hardware, multiple electricity tiers, major public pool data) to answer “can you still mine?” — not as macro narrative, but as one machine, one kilowatt-hour, one month of profit.
The four variables of 2026 mining economics
Mining ROI hinges on four variables, all four of which are moving in 2026:
Variable one: BTC price — BTC traded between 73K and 78K in May 2026, above the halving level (~65K in April 2024) but well below the 2025 peak (110K). The dollar value mined per machine per day is 12-20% higher than at halving but 30-35% below the 2025 peak.
Variable two: network hashrate — May 2026 hashrate sits near 750 EH/s, up 25% from 600 EH/s at the halving. Network growth has clearly decelerated through late 2025 as price pressure pushed marginal miners offline — annualized hashrate growth fell from 40% to 15-20%.
Variable three: rig efficiency — mainstream rigs moved from 21.5 J/TH (S19 XP, 2024) to 13.5 J/TH (S21 Pro, 2026), a 37% efficiency improvement. Same output, 37% less power — the biggest variable shift of the last two years.
Variable four: electricity cost — large US farms 0.04-0.07 USD/kWh, parts of Central Asia and South America 0.025-0.04 USD/kWh, European residential 0.15-0.30 USD/kWh. The most sensitive variable: a single cent per kWh determines whether you’re net positive or net negative.
For the full halving-cycle logic, Bitcoin halving cycle compares the price paths across all four halvings.
A real S21 Pro calculation across electricity tiers
The S21 Pro is the dominant 2026 model, with specs:
- Hashrate: 234 TH/s
- Power draw: 3500 W
- Efficiency: 15 J/TH (realised running)
- Per-unit price: 3,800 USD (May 2026)
Assumed May 2026 averages:
- BTC price 75,000
- Network hashrate 750 EH/s
- Daily yield per TH/s after difficulty adjustment: 0.0000004 BTC
- Pool fee: 1.5%
- Maintenance and depreciation: 0.005 USD per TH per day
Monthly ROI by electricity tier:
| Electricity (USD/kWh) | Daily power | Daily gross | Daily net | Monthly net | Payback (months) |
|---|---|---|---|---|---|
| 0.025 | 2.10 | 7.02 | 4.92 | 147 | 25.8 |
| 0.035 | 2.94 | 7.02 | 4.08 | 122 | 31.1 |
| 0.045 | 3.78 | 7.02 | 3.24 | 97 | 39.2 |
| 0.055 | 4.62 | 7.02 | 2.40 | 72 | 52.8 |
| 0.065 | 5.46 | 7.02 | 1.56 | 47 | 80.9 |
| 0.080 | 6.72 | 7.02 | 0.30 | 9 | 422 |
| 0.100 | 8.40 | 7.02 | -1.38 | -41 | Loss |
What the table says about 2026 mining:
- Below 0.04 USD/kWh: stable profit, 25-39 month payback
- 0.04 to 0.06 USD/kWh: marginally profitable, 40-50 month payback (near rig lifespan)
- 0.06 to 0.08 USD/kWh: “depends entirely on BTC price” zone
- Above 0.08 USD/kWh: no new buildouts viable, old rigs going offline
- Above 0.10 USD/kWh: structurally a loss — residential mining is unviable in 2026

The “daily slice” after halving
A more visceral number — how much BTC does one S21 Pro actually mine in a day in May 2026?
Theoretical daily yield = 234 TH/s ÷ 750,000,000 TH/s × 144 blocks × 3.125 BTC × 90% (pool and orphan adjustment)
Plugging in: 234 / 750,000,000 × 144 × 3.125 × 0.9 ≈ 0.0000935 BTC ≈ 0.0001 BTC
So roughly 0.0001 BTC per day, or 7.5 USD gross at 75K BTC. That number is roughly half of the equivalent in March 2024 (pre-halving): the same machine on the same power was earning around 0.00017 BTC per day, or roughly 11 USD gross at the 65K BTC price.
The halving’s impact is exactly that direct: gross revenue halves, electricity doesn’t change, efficiency improvements don’t fully compensate — so miner profit drops by more than half, not just half. This explains why after the April 2024 halving, network-wide rig downtime briefly hit 10-15% (farms paying over 0.07 USD/kWh widely shutting off).
Pool selection: Foundry, AntPool, F2Pool data
Pool choice directly affects daily revenue stability. May 2026 comparisons:
| Pool | Network share | Fee | Settlement | Daily per TH/s (net) |
|---|---|---|---|---|
| Foundry USA | 32% | 1.0% | FPPS | 0.0000004001 BTC |
| AntPool | 18% | 1.5% | FPPS | 0.0000003981 BTC |
| F2Pool | 12% | 2.5% | PPS+ | 0.0000003939 BTC |
| ViaBTC | 9% | 2.0% | PPS+/PPLNS toggle | 0.0000003960 BTC |
| Binance Pool | 8% | 2.5% | FPPS | 0.0000003939 BTC |
Foundry is the most efficient pool right now — low fees, stable settlement, default for large farms. F2Pool and ViaBTC retain Chinese-community share but carry higher fees, which compounds against smaller miners.

Hidden costs that lengthen the payback period
The table above is an idealised model. Several hidden costs extend real payback periods:
- Hardware maintenance: S21 Pro averages 3-7 fault days per year, equivalent to 1-2% capacity loss
- Cooling costs: in southern climates, summer AC or immersion cooling adds 10-15% to total power
- Network and monitoring: 2-5 USD per machine per month
- Hosting rent: colocation farms typically charge 0.005-0.015 USD/kWh as a “management fee”
- Price volatility: slippage on BTC sold during drawdowns, roughly 2-3% per year
Adding these in, real payback periods typically run 15-25% longer than the table. A miner at 0.045 USD/kWh may see 47 months instead of 39 — approaching the economic life of the rig (48-60 months). The implication: real safe electricity ceiling for 2026 mining is roughly 0.05 USD/kWh; above that, only special situations are profitable.
For a granular electricity breakdown, Bitcoin mining electricity cost goes deeper.
ASIC vs GPU
The 2026 answer is clear: don’t GPU-mine BTC. ASIC long dominant, BTC GPU mining economically near-zero. Other GPU-mineable chains (KAS, ETC, RVN) have small caps, thin liquidity, long-term holding risk. Existing GPUs on NiceHash for electricity offset is fine, not as a primary vehicle.
Practical paths by scale
- Home miners (1-5 rigs): above 0.10 USD/kWh walk away; 0.08-0.10 only if rigs already owned; below 0.08 viable with long payback; alternative: holding BTC often outperforms.
- Mid-size farms (50-500): must secure 0.04-0.05 USD/kWh; prioritize on-site renewable consumption; FPPS pools; BTC futures hedge.
- Large farms (5000+): 0.03-0.04 USD/kWh table stakes; heat recovery, AI compute hybrid; equity/debt funding to reduce unit cost; waste-heat for greenhouse or district heating.
- Pure passive investors: listed miners (MARA, RIOT, CIPHER) or BTC spot ETFs (IBIT, FBTC). ETFs at Bitcoin spot ETF.
Twelve-month outlook
Four variables: BTC price (reclaims 100K → miners under 0.08 comfortable, drops below 60K → above 0.05 shutting off); network hashrate (decelerated, S23 at 10 J/TH could re-accelerate); energy policy (TX/WY welcoming, NY restricting, Europe trending restrictive); AI compute competing for electricity — 2026’s biggest wildcard, AI data centres pay 3-5x what miners pay, cheap power being absorbed, miner electricity floor lifting passively.
Most realistic counsel: use BTC spot ETFs or direct BTC holdings for price exposure first, treat mining as additional yield only when you have access to cheap power. The recurring halving lesson — block subsidy halves, players migrate from households to institutions to listed companies to energy operators. The migration continues.
