Bitaxe Gamma on Fractal — Mining Truth Benchmark & Specifications

Consolidated PoW oracle metrics for operating a Bitaxe Gamma on Fractal (FB) at live network difficulty and benchmark industrial electricity (0.069 USD/kWh):

Can you solo mine Fractal with a Bitaxe Gamma?

Yes — a Bitaxe Gamma (1.10 TH/s) can solo mine Fractal (FB) via a solo pool. At Fractal's 129.31 PH/s SHA-256 network that is about 6 blocks per year — expected one block roughly every 61 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 Gamma 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 Fractal, it ranks #5 in electrical efficiency (60,958,333,333.33 H/W) and #9 in raw hashrate (1.10 TH/s).

Electricity Operating Costs & Breakeven

Running a Bitaxe Gamma (18 W) pulls about 0.43 kWh per day (13.1 kWh per month). At the standard rate of 0.069 USD/kWh, electricity costs roughly 0.03 USD per day (0.91 USD/month or 11 USD/year). Statistically that year returns 5.95 blocks, worth about $13.95 — expected revenue covers the power bill about 1.3x over.

The operational breakeven threshold is 0.088 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): -0.01 USD / day

Break-even Coin Price Target: For this hardware to break even on electricity, Fractal must trade at or above 0.2927 USD at standard industrial power (0.069 USD/kWh), or 0.5091 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 61 days, real-world dispersion ranges across 5% and 50% quantiles:

• Lucky streak (5% Odds): Block within ~3 days (1-in-20 fastest discovery, power cost: ~0 USD)
• Median expectation (50% Odds): Block within ~43 days (Nominal median, power cost: ~1 USD)
• Bad luck streak (5% Odds): Can stretch up to ~184 days (1-in-20 extended dry spell, power cost: ~5 USD)

High Variance Alert: In a 1-in-20 severe drought (~184 days), cumulative electricity burned (~5 USD) will exceed the block reward value (2 USD). Pool mining is recommended for risk-averse operators.

Bitaxe Gamma Price & Estimated ROI

Current market price: $180–$260 (estimated market price, median $220) (Hardware price estimated). Mined against its most profitable coin instead of solo, it would pay itself back in about 45.1 years.

How the odds have moved

Fractal's network hashrate fell 48% since 2026-09-22, from 250.33 PH/s to 129.31 PH/s — so the same rig is now 48% more likely to find a block.

Where to point a Bitaxe Gamma 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 12 solo pools for Fractal with their stratum endpoints, fees, and pool hashrates — see Fractal solo mining pools:

• jackpool.ru (Fee: 0.5% · Hashrate: 708.08 TH/s)
• mining-dutch.nl (Fee: 1% · Hashrate: 501.82 TH/s)
• pool.kryptex.com (Fee: 1.5% · Hashrate: 31.11 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 1.62%, yearly chance 99.74%.

Frequently Asked Questions: Bitaxe Gamma on Fractal

Can you solo mine Fractal with a Bitaxe Gamma?

Yes — a Bitaxe Gamma (1.10 TH/s) can solo mine Fractal (FB) via a solo pool. At Fractal's 129.31 PH/s SHA-256 network that is about 6 blocks per year — expected one block roughly every 61 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 Gamma stand?

SHA-256 is an ASIC-dominated algorithm. The Bitaxe Gamma delivers 1.10 TH/s (#9 of 9 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 Gamma on Fractal?

At 18 W, operating a Bitaxe Gamma consumes 0.43 kWh/day (13.1 kWh/month). At standard electricity (0.069 USD/kWh), the power bill is 0.03 USD/day (0.91 USD/month). The operational breakeven threshold is 0.088 USD/kWh.

What happens if my Bitaxe Gamma 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 184 days, accumulating roughly 5 USD in power costs.
