Bitaxe Gamma 602 on Fractal — Mining Truth Benchmark & Specifications

Consolidated PoW oracle metrics for operating a Bitaxe Gamma 602 on Fractal (FB) at live network difficulty and benchmark industrial electricity (0.069 USD/kWh):

Can you solo mine Fractal with a Bitaxe Gamma 602?

Yes — a Bitaxe Gamma 602 (1.30 TH/s) can solo mine Fractal (FB) via a solo pool. At Fractal's 129.31 PH/s SHA-256 network that is about 7 blocks per year — expected one block roughly every 52 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 602 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 #1 in electrical efficiency (86,597,333,333.33 H/W) and #7 in raw hashrate (1.30 TH/s).

Electricity Operating Costs & Breakeven

Running a Bitaxe Gamma 602 (15 W) pulls about 0.36 kWh per day (11.0 kWh per month). At the standard rate of 0.069 USD/kWh, electricity costs roughly 0.02 USD per day (0.76 USD/month or 9 USD/year). Statistically that year returns 7.04 blocks, worth about $16.51 — expected revenue covers the power bill about 1.8x over.

The operational breakeven threshold is 0.126 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): +0.02 USD / day
• At 0.120 USD/kWh (Residential Grid): +0.00 USD / day

Break-even Coin Price Target: For this hardware to break even on electricity, Fractal must trade at or above 0.2061 USD at standard industrial power (0.069 USD/kWh), or 0.3584 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 52 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 ~36 days (Nominal median, power cost: ~1 USD)
• Bad luck streak (5% Odds): Can stretch up to ~155 days (1-in-20 extended dry spell, power cost: ~4 USD)

High Variance Alert: In a 1-in-20 severe drought (~155 days), cumulative electricity burned (~4 USD) will exceed the block reward value (2 USD). Pool mining is recommended for risk-averse operators.

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 602 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

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 1.91%, yearly chance 99.91%.

Frequently Asked Questions: Bitaxe Gamma 602 on Fractal

Can you solo mine Fractal with a Bitaxe Gamma 602?

Yes — a Bitaxe Gamma 602 (1.30 TH/s) can solo mine Fractal (FB) via a solo pool. At Fractal's 129.31 PH/s SHA-256 network that is about 7 blocks per year — expected one block roughly every 52 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 602 stand?

SHA-256 is an ASIC-dominated algorithm. The Bitaxe Gamma 602 delivers 1.30 TH/s (#7 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 602 on Fractal?

At 15 W, operating a Bitaxe Gamma 602 consumes 0.36 kWh/day (11.0 kWh/month). At standard electricity (0.069 USD/kWh), the power bill is 0.02 USD/day (0.76 USD/month). The operational breakeven threshold is 0.126 USD/kWh.

What happens if my Bitaxe Gamma 602 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 155 days, accumulating roughly 4 USD in power costs.
