Can you solo mine Fractal with a Bitaxe NerdQaxe?
Yes — a Bitaxe NerdQaxe (2.40 TH/s) can solo mine Fractal (FB) via a solo pool. At Fractal's 153.88 PH/s SHA-256 network that is about 12 blocks per year — expected one block roughly every 31 days, for the full 6.2500 FB (≈ 2 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 Fractal
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 Fractal, it ranks #5 in electrical efficiency (43,710,545,454.55 H/W) and #4 in raw hashrate (2.40 TH/s).
Electricity Operating Costs & Breakeven
Running a Bitaxe NerdQaxe (55 W) pulls about 1.32 kWh per day (40.2 kWh per month). At the standard rate of 0.069 USD/kWh, electricity costs roughly 0.09 USD per day (2.77 USD/month or 33 USD/year). Statistically that year returns 11.74 blocks, worth about $28.64 — you would burn roughly 1x more in electricity than that reward is worth.
The operational breakeven threshold is 0.059 USD/kWh. Expected net operating margin at benchmark tariffs:
- At 0.040 USD/kWh (Hydro / Renewable): +0.03 USD / day
- At 0.069 USD/kWh (Standard Industrial): -0.01 USD / day
- At 0.120 USD/kWh (Residential Grid): -0.08 USD / day
Break-even Coin Price Target: For this hardware to break even on electricity, Fractal must trade at or above 0.4534 USD at standard industrial power (0.069 USD/kWh), or 0.7886 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 31 days, real-world dispersion ranges across 5% and 50% quantiles:
- Lucky streak (5% Odds): Block within ~2 days (1-in-20 fastest discovery, power cost: ~0 USD)
- Median expectation (50% Odds): Block within ~22 days (Nominal median, power cost: ~2 USD)
- Bad luck streak (5% Odds): Can stretch up to ~93 days (1-in-20 extended dry spell, power cost: ~8 USD)
High Variance Alert: In a 1-in-20 severe drought (~93 days), cumulative electricity burned (~8 USD) will exceed the block reward value (2 USD). Pool mining is recommended for risk-averse operators.
Bitaxe NerdQaxe Price & Estimated ROI
Current market price: $220–$320 (estimated market price, median $270) (Hardware price estimated). Mined against its most profitable coin instead of solo, it would pay itself back in about 46.6 years.
How other hardware compares on Fractal

How the odds have moved
Fractal's network hashrate climbed 22% since 2026-09-08, from 125.95 PH/s to 153.88 PH/s — so the same rig is now 22% less likely to find a block.
Where to point a Bitaxe NerdQaxe at Fractal
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 10 solo pools for Fractal with their stratum endpoints, fees, and pool hashrates — see Fractal solo mining pools:
- jackpool.ru (Fee: 0.5% · Hashrate: 582.05 TH/s)
- pool.kryptex.com (Fee: 1.5% · Hashrate: 18.83 PH/s)
- hashpoolpro.com (Fee: 2% · Hashrate: 4.22 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 3.16%, yearly chance 100.00%.
Frequently Asked Questions: Bitaxe NerdQaxe on Fractal
Can you solo mine Fractal with a Bitaxe NerdQaxe?
Yes — a Bitaxe NerdQaxe (2.40 TH/s) can solo mine Fractal (FB) via a solo pool. At Fractal's 153.88 PH/s SHA-256 network that is about 12 blocks per year — expected one block roughly every 31 days, for the full 6.2500 FB (≈ 2 USD) block. BackPoW computes this from live network difficulty using a Poisson block-discovery model.
Is SHA-256 ASIC-resistant, and where does the Bitaxe NerdQaxe stand?
SHA-256 is an ASIC-dominated algorithm. The Bitaxe NerdQaxe delivers 2.40 TH/s (#4 of 5 models on Fractal). 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 Fractal?
At 55 W, operating a Bitaxe NerdQaxe consumes 1.32 kWh/day (40.2 kWh/month). At standard electricity (0.069 USD/kWh), the power bill is 0.09 USD/day (2.77 USD/month). The operational breakeven threshold is 0.059 USD/kWh.
What happens if my Bitaxe NerdQaxe encounters a severe dry spell on Fractal?
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 93 days, accumulating roughly 8 USD in power costs.
