Can you solo mine Quai-SHA with a NerdMiner NerdQaxe+?
Yes — a NerdMiner NerdQaxe+ (2.50 TH/s) can solo mine Quai-SHA (QUAI) via a solo pool. At Quai-SHA's 149.55 PH/s SHA-256 network that is about 436 blocks per year — expected one block roughly every 20.1 hours, for the full 9.7800 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 NerdMiner 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 9 tracked models on Quai-SHA, it ranks #8 in electrical efficiency (49,950,000,000.00 H/W) and #5 in raw hashrate (2.50 TH/s).
Electricity Operating Costs & Breakeven
Running a NerdMiner NerdQaxe+ (50 W) pulls about 1.20 kWh per day (36.5 kWh per month). At the standard rate of 0.069 USD/kWh, electricity costs roughly 0.08 USD per day (2.52 USD/month or 30 USD/year). Statistically that year returns 435.54 blocks, worth about $34.18 — expected revenue covers the power bill about 1.1x over.
The operational breakeven threshold is 0.078 USD/kWh. Expected net operating margin at benchmark tariffs:
- At 0.040 USD/kWh (Hydro / Renewable): +0.05 USD / day
- At 0.069 USD/kWh (Standard Industrial): +0.01 USD / day
- At 0.120 USD/kWh (Residential Grid): -0.05 USD / day
Break-even Coin Price Target: For this hardware to break even on electricity, Quai-SHA must trade at or above 0.00710 USD at standard industrial power (0.069 USD/kWh), or 0.0123 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 20.1 hours, real-world dispersion ranges across 5% and 50% quantiles:
- Lucky streak (5% Odds): Block within ~1.0 hours (1-in-20 fastest discovery, power cost: ~0 USD)
- Median expectation (50% Odds): Block within ~14.0 hours (Nominal median, power cost: ~0 USD)
- Bad luck streak (5% Odds): Can stretch up to ~3 days (1-in-20 extended dry spell, power cost: ~0 USD)
High Variance Alert: In a 1-in-20 severe drought (~3 days), cumulative electricity burned (~0 USD) will exceed the block reward value (0 USD). Pool mining is recommended for risk-averse operators.

How the odds have moved
Quai-SHA's network hashrate climbed 4% since 2026-09-22, from 144.04 PH/s to 149.55 PH/s — so the same rig is now 4% less likely to find a block.
Where to point a NerdMiner NerdQaxe+ at Quai-SHA
Solo mining still runs through a solo pool: it handles the block template and pays the full reward to whoever finds the block. BackPoW tracks 7 solo pools for Quai-SHA with their stratum endpoints, fees, and pool hashrates — see Quai-SHA solo mining pools:
- stratumx.org (Fee: 0% · Hashrate: 6.55 PH/s)
- 2miners.com (Fee: 1.5% · Hashrate: 2.11 PH/s)
- k1pool.com (Fee: 2% · Hashrate: 1.46 PH/s)
How the odds are calculated
Because each hash succeeds independently, finding a block is a Poisson process — there is no 'due' block, only an average rate. The mean time between blocks is T = network_hashrate ÷ your_hashrate × block_time, and the realistic chance of at least one block over a period t is P = 1 − e^(−t/T). That is why a longer run raises your odds but never guarantees a block. For this pair: daily chance 69.65%, yearly chance 100.00%.
Frequently Asked Questions: NerdMiner NerdQaxe+ on Quai-SHA
Can you solo mine Quai-SHA with a NerdMiner NerdQaxe+?
Yes — a NerdMiner NerdQaxe+ (2.50 TH/s) can solo mine Quai-SHA (QUAI) via a solo pool. At Quai-SHA's 149.55 PH/s SHA-256 network that is about 436 blocks per year — expected one block roughly every 20.1 hours, for the full 9.7800 QUAI block. BackPoW computes this from live network difficulty using a Poisson block-discovery model.
Is SHA-256 ASIC-resistant, and where does the NerdMiner NerdQaxe+ stand?
SHA-256 is an ASIC-dominated algorithm. The NerdMiner NerdQaxe+ delivers 2.50 TH/s (#5 of 9 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 NerdMiner NerdQaxe+ on Quai-SHA?
At 50 W, operating a NerdMiner NerdQaxe+ consumes 1.20 kWh/day (36.5 kWh/month). At standard electricity (0.069 USD/kWh), the power bill is 0.08 USD/day (2.52 USD/month). The operational breakeven threshold is 0.078 USD/kWh.
What happens if my NerdMiner 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 3 days, accumulating roughly 0 USD in power costs.
