Can you solo mine eCash with a NerdMiner NerdQaxe+?
Yes — a NerdMiner NerdQaxe+ (2.50 TH/s) can solo mine eCash (XEC) via a solo pool. At eCash's 62.15 PH/s SHA-256 network that is about 2 blocks per year — expected one block roughly every 166 days, for the full 1,812,500.0000 XEC (≈ 12 USD) 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 eCash
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 eCash, 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 2.20 blocks, worth about $26.33 — you would burn roughly 1x more in electricity than that reward is worth.
The operational breakeven threshold is 0.060 USD/kWh. Expected net operating margin at benchmark tariffs:
- At 0.040 USD/kWh (Hydro / Renewable): +0.02 USD / day
- At 0.069 USD/kWh (Standard Industrial): -0.01 USD / day
- At 0.120 USD/kWh (Residential Grid): -0.07 USD / day
Break-even Coin Price Target: For this hardware to break even on electricity, eCash must trade at or above 0.00000758 USD at standard industrial power (0.069 USD/kWh), or 0.0000132 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 166 days, real-world dispersion ranges across 5% and 50% quantiles:
- Lucky streak (5% Odds): Block within ~9 days (1-in-20 fastest discovery, power cost: ~1 USD)
- Median expectation (50% Odds): Block within ~115 days (Nominal median, power cost: ~10 USD)
- Bad luck streak (5% Odds): Can stretch up to ~1.36 yr (1-in-20 extended dry spell, power cost: ~41 USD)
High Variance Alert: In a 1-in-20 severe drought (~1.36 yr), cumulative electricity burned (~41 USD) will exceed the block reward value (12 USD). Pool mining is recommended for risk-averse operators.

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 0.6008%, yearly chance 88.93%.
Frequently Asked Questions: NerdMiner NerdQaxe+ on eCash

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 eCash). 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 eCash?
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 0.060 USD/kWh.
What happens if my NerdMiner NerdQaxe+ encounters a severe dry spell on eCash?
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 1.36 yr, accumulating roughly 41 USD in power costs.
