Can you solo mine Quai-SHA with a Bitaxe NerdQaxe++?
Yes — a Bitaxe NerdQaxe++ (4.81 TH/s) can solo mine Quai-SHA (QUAI) via a solo pool. At Quai-SHA's 160.34 PH/s SHA-256 network that is about 717 blocks per year — expected one block roughly every 12.2 hours, for the full 10.9500 QUAI block. BackPoW computes this from live network difficulty using a Poisson block-discovery model. Realistically this is genuinely worth a patient solo run.
Hardware Tier & Ecosystem Ranking on Quai-SHA
The Bitaxe NerdQaxe++ is categorized in the Home / Solo Lottery Tier (Compact or low-power hardware optimized for decentralized solo lottery participation rather than commercial pool revenue.). Among all 5 tracked models on Quai-SHA, it ranks #2 in electrical efficiency (63,258,947,368.42 H/W) and #3 in raw hashrate (4.81 TH/s).
Electricity Operating Costs & Breakeven
Running a Bitaxe NerdQaxe++ (76 W) pulls about 1.82 kWh per day (55.5 kWh per month). At the standard rate of 0.069 USD/kWh, electricity costs roughly 0.13 USD per day (3.83 USD/month or 46 USD/year). Statistically that year returns 716.83 blocks, worth about $75.38 — expected revenue covers the power bill about 1.6x over.
The operational breakeven threshold is 0.113 USD/kWh. Expected net operating margin at benchmark tariffs:
- At 0.040 USD/kWh (Hydro / Renewable): +0.13 USD / day
- At 0.069 USD/kWh (Standard Industrial): +0.08 USD / day
- At 0.120 USD/kWh (Residential Grid): -0.01 USD / day
Break-even Coin Price Target: For this hardware to break even on electricity, Quai-SHA must trade at or above 0.00586 USD at standard industrial power (0.069 USD/kWh), or 0.0102 USD at residential power (0.120 USD/kWh).
Bankroll & Variance Risk Simulator
Solo mining block discovery follows a memoryless Poisson distribution. While the average wait is 12.2 hours, real-world dispersion ranges across 5% and 50% quantiles:
- Lucky streak (5% Odds): Block within ~37.6 min (1-in-20 fastest discovery, power cost: ~0 USD)
- Median expectation (50% Odds): Block within ~8.5 hours (Nominal median, power cost: ~0 USD)
- Bad luck streak (5% Odds): Can stretch up to ~2 days (1-in-20 extended dry spell, power cost: ~0 USD)
High Variance Alert: In a 1-in-20 severe drought (~2 days), cumulative electricity burned (~0 USD) will exceed the block reward value (0 USD). Pool mining is recommended for risk-averse operators.
Bitaxe NerdQaxe++ Price & Estimated ROI
Current market price: $340–$460 (estimated market price, median $400) (Hardware price estimated). Mined against its most profitable coin instead of solo, it would pay itself back in about 12.4 years.
How other hardware compares on Quai-SHA
Devices in the same hashrate class, solo mining Quai-SHA at today's difficulty:
| Hardware | Hashrate | Expected block | Chance in 1 year |
|---|---|---|---|
| Bitaxe NerdOctaxe | 9.61 TH/s | 6.1 hours | 100.00% |
| Bitaxe NerdQaxe++ Rev 6.1 | 6.00 TH/s | 9.8 hours | 100.00% |
| Bitaxe NerdQaxe | 2.40 TH/s | 1 days | 100.00% |

How the odds have moved
Quai-SHA's network hashrate fell 36% since 2026-09-08, from 250.17 PH/s to 160.34 PH/s — so the same rig is now 36% more likely to find a block.
How the odds are calculated
Each hash is an independent attempt, so block discovery is memoryless and follows an exponential distribution. The average time to a block is T = network_hashrate ÷ your_hashrate × block_time. The chance of hitting at least one block within a period t is then given by the Poisson relation P = 1 − e^(−t/T) — the realistic probability, not a misleading linear one. For this pair: daily chance 85.95%, yearly chance 100.00%.
Frequently Asked Questions: Bitaxe NerdQaxe++ on Quai-SHA

Is SHA-256 ASIC-resistant, and where does the Bitaxe NerdQaxe++ stand?
SHA-256 is an ASIC-dominated algorithm. The Bitaxe NerdQaxe++ delivers 4.81 TH/s (#3 of 5 models on Quai-SHA). It belongs to the Home / Solo Lottery Tier, built for compact, decentralized solo attempts rather than commercial pool income.
What is the operating power cost and breakeven electricity rate for a Bitaxe NerdQaxe++ on Quai-SHA?
At 76 W, operating a Bitaxe NerdQaxe++ consumes 1.82 kWh/day (55.5 kWh/month). At standard electricity (0.069 USD/kWh), the power bill is 0.13 USD/day (3.83 USD/month). The operational breakeven threshold is 0.113 USD/kWh.
What happens if my Bitaxe NerdQaxe++ encounters a severe dry spell on Quai-SHA?
Block discovery is an independent Poisson process with no memory. In a 1-in-20 bad luck drought (5% worst luck), finding a block can stretch up to 2 days, accumulating roughly 0 USD in power costs.
