Can you solo mine Bitcoin with a Bitaxe Ultra 1366?
Yes — a Bitaxe Ultra 1366 (425.55 GH/s) can solo mine Bitcoin (BTC) via a solo pool. At Bitcoin's 1089.78 EH/s SHA-256 network that is about a 1-in-45,828 chance per year — expected one block roughly every 45,827 yr, for the full 3.1400 BTC (≈ 259,574 USD) block. BackPoW computes this from live network difficulty using a Poisson block-discovery model. Realistically this is a hobby/lottery play rather than an income strategy.
Hardware Tier & Ecosystem Ranking on Bitcoin
The Bitaxe Ultra 1366 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 35 tracked models on Bitcoin, it ranks #34 in electrical efficiency (38,686,590,909.09 H/W) and #35 in raw hashrate (425.55 GH/s).
Electricity Operating Costs & Breakeven
Running a Bitaxe Ultra 1366 (11 W) pulls about 0.26 kWh per day (8.0 kWh per month). At the standard rate of 0.069 USD/kWh, electricity costs roughly 0.02 USD per day (0.55 USD/month or 7 USD/year). Statistically the reward you can expect across that year is about $5.66 — you would burn roughly 1x more in electricity than that reward is worth. That is an expected value averaged over far more time than the hardware will last, not income to plan around: the overwhelmingly likely outcome in any given year is no block at all.
The operational breakeven threshold is 0.059 USD/kWh. Expected net operating margin at benchmark tariffs:
- At 0.040 USD/kWh (Hydro / Renewable): +0.00 USD / day
- At 0.069 USD/kWh (Standard Industrial): -0.00 USD / day
- At 0.120 USD/kWh (Residential Grid): -0.02 USD / day
Break-even Coin Price Target: For this hardware to break even on electricity, Bitcoin must trade at or above 97,104.22 USD at standard industrial power (0.069 USD/kWh), or 168,876.91 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 45,827 yr, real-world dispersion ranges across 5% and 50% quantiles:
- Lucky streak (5% Odds): Block within ~2,351 yr (1-in-20 fastest discovery, power cost: ~15,640 USD)
- Median expectation (50% Odds): Block within ~31,765 yr (Nominal median, power cost: ~211,346 USD)
- Bad luck streak (5% Odds): Can stretch up to ~137,286 yr (1-in-20 extended dry spell, power cost: ~913,421 USD)
High Variance Alert: In a 1-in-20 severe drought (~137,286 yr), cumulative electricity burned (~913,421 USD) will exceed the block reward value (259,574 USD). Pool mining is recommended for risk-averse operators.
How other hardware compares on Bitcoin
Devices in the same hashrate class, solo mining Bitcoin at today's difficulty:
| Hardware | Hashrate | Expected block | Chance in 1 year |
|---|---|---|---|
| Bitaxe Gamma 601 | 1.20 TH/s | 16,263 yr | 0.0061% |
| Bitaxe Gamma | 1.10 TH/s | 17,773 yr | 0.0056% |
| Bitaxe Supra | 599.34 GH/s | 32,539 yr | 0.0031% |
| Bitaxe Supra 401 | 598.44 GH/s | 32,588 yr | 0.0031% |
| Bitaxe Ultra | 498.85 GH/s | 39,094 yr | 0.0026% |
How the odds have moved
Bitcoin's network hashrate climbed 3% since 2026-09-22, from 1052.97 EH/s to 1089.78 EH/s — so the same rig is now 3% less likely to find a block.
Where to point a Bitaxe Ultra 1366 at Bitcoin
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 81 solo pools for Bitcoin with their stratum endpoints, fees, and pool hashrates — see Bitcoin solo mining pools:

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 6e-06%, yearly chance 0.0022%.
Frequently Asked Questions: Bitaxe Ultra 1366 on Bitcoin
Can you solo mine Bitcoin with a Bitaxe Ultra 1366?
Yes — a Bitaxe Ultra 1366 (425.55 GH/s) can solo mine Bitcoin (BTC) via a solo pool. At Bitcoin's 1089.78 EH/s SHA-256 network that is about a 1-in-45,828 chance per year — expected one block roughly every 45,827 yr, for the full 3.1400 BTC (≈ 259,574 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 Ultra 1366 stand?
SHA-256 is an ASIC-dominated algorithm. The Bitaxe Ultra 1366 delivers 425.55 GH/s (#35 of 35 models on Bitcoin). 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 Ultra 1366 on Bitcoin?
At 11 W, operating a Bitaxe Ultra 1366 consumes 0.26 kWh/day (8.0 kWh/month). At standard electricity (0.069 USD/kWh), the power bill is 0.02 USD/day (0.55 USD/month). The operational breakeven threshold is 0.059 USD/kWh.
What happens if my Bitaxe Ultra 1366 encounters a severe dry spell on Bitcoin?
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 137,286 yr, accumulating roughly 913,421 USD in power costs.
