Can you solo mine DGB-SHA with a NerdMiner NerdOCTAxe Rev 3.1?
Yes — a NerdMiner NerdOCTAxe Rev 3.1 (12.00 TH/s) can solo mine DGB-SHA (DGB) via a solo pool. At DGB-SHA's 33.58 PH/s SHA-256 network that is about 150 blocks per year — expected one block roughly every 2 days, for the full 247.9300 DGB 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 DGB-SHA
The NerdMiner NerdOCTAxe Rev 3.1 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 15 tracked models on DGB-SHA, it ranks #9 in electrical efficiency (49,980,000,000.00 H/W) and #1 in raw hashrate (12.00 TH/s).
Electricity Operating Costs & Breakeven
Running a NerdMiner NerdOCTAxe Rev 3.1 (240 W) pulls about 5.76 kWh per day (175.3 kWh per month). At the standard rate of 0.069 USD/kWh, electricity costs roughly 0.40 USD per day (12.10 USD/month or 145 USD/year). Statistically that year returns 150.30 blocks, worth about $126 — 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): +0.11 USD / day
- At 0.069 USD/kWh (Standard Industrial): -0.05 USD / day
- At 0.120 USD/kWh (Residential Grid): -0.35 USD / day
Break-even Coin Price Target: For this hardware to break even on electricity, DGB-SHA must trade at or above 0.00390 USD at standard industrial power (0.069 USD/kWh), or 0.00678 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 2 days, real-world dispersion ranges across 5% and 50% quantiles:
- Lucky streak (5% Odds): Block within ~3.0 hours (1-in-20 fastest discovery, power cost: ~0 USD)
- Median expectation (50% Odds): Block within ~2 days (Nominal median, power cost: ~1 USD)
- Bad luck streak (5% Odds): Can stretch up to ~7 days (1-in-20 extended dry spell, power cost: ~3 USD)
High Variance Alert: In a 1-in-20 severe drought (~7 days), cumulative electricity burned (~3 USD) will exceed the block reward value (1 USD). Pool mining is recommended for risk-averse operators.

How the odds have moved
DGB-SHA's network hashrate fell 18% since 2026-09-22, from 41.08 PH/s to 33.58 PH/s — so the same rig is now 18% more likely to find a block.
Where to point a NerdMiner NerdOCTAxe Rev 3.1 at DGB-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 36 solo pools for DGB-SHA with their stratum endpoints, fees, and pool hashrates — see DGB-SHA solo mining pools:
- sololuck.io (Fee: 0% · Hashrate: 165.40 TH/s)
- grandpool.io (Fee: 0.01% · Hashrate: 660.51 TH/s)
- fenixpool.com (Fee: 0.5% · Hashrate: 808.41 TH/s)
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 33.73%, yearly chance 100.00%.
