Can you solo mine Bitcoin with a Bitaxe Ultra?
Yes — a Bitaxe Ultra (498.85 GH/s) can solo mine Bitcoin (BTC) via a solo pool. At Bitcoin's 973.63 EH/s SHA-256 network that is about a 1-in-36,967 chance per year — expected one block roughly every 36,966 yr, for the full 3.1400 BTC (≈ 263,810 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 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 22 tracked models on Bitcoin, it ranks #22 in electrical efficiency (33,256,666,666.67 H/W) and #22 in raw hashrate (498.85 GH/s).
Electricity Operating Costs & Breakeven
Running a Bitaxe Ultra (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 the reward you can expect across that year is about $7.14 — 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 0.054 USD/kWh. Expected net operating margin at benchmark tariffs:
- At 0.040 USD/kWh (Hydro / Renewable): +0.01 USD / day
- At 0.069 USD/kWh (Standard Industrial): -0.01 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 106,811.59 USD at standard industrial power (0.069 USD/kWh), or 185,759.29 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 36,966 yr, real-world dispersion ranges across 5% and 50% quantiles:
- Lucky streak (5% Odds): Block within ~1,896 yr (1-in-20 fastest discovery, power cost: ~17,203 USD)
- Median expectation (50% Odds): Block within ~25,623 yr (Nominal median, power cost: ~232,474 USD)
- Bad luck streak (5% Odds): Can stretch up to ~110,741 yr (1-in-20 extended dry spell, power cost: ~1,004,734 USD)
High Variance Alert: In a 1-in-20 severe drought (~110,741 yr), cumulative electricity burned (~1,004,734 USD) will exceed the block reward value (263,810 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 NerdQaxe++ | 4.81 TH/s | 3,836 yr | 0.0261% |
| Bitaxe Supra Hex | 4.19 TH/s | 4,398 yr | 0.0227% |
| Bitaxe NerdQaxe | 2.40 TH/s | 7,671 yr | 0.0130% |
| Bitaxe Gamma | 1.10 TH/s | 16,806 yr | 0.0059% |
| Bitaxe Supra | 599.34 GH/s | 30,768 yr | 0.0033% |
How the odds have moved
Bitcoin's network hashrate climbed 9% since 2026-09-08, from 893.10 EH/s to 973.63 EH/s — so the same rig is now 9% less likely to find a block.
Where to point a Bitaxe Ultra 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 82 solo pools for Bitcoin with their stratum endpoints, fees, and pool hashrates — see Bitcoin solo mining pools:
- web.public-pool.io (Fee: 0% · Hashrate: 50.42 PH/s)
- pool.solomining.de (Fee: 0% · Hashrate: 7.91 PH/s)
- nexuspool.io (Fee: 0% · Hashrate: 5.80 PH/s)
How the odds are calculated
Solo mining is memoryless: every hash is an independent lottery ticket, so the wait for a block follows an exponential distribution rather than a fixed schedule. On average a block takes T = network_hashrate ÷ your_hashrate × block_time, and the probability of finding at least one within a window t is P = 1 − e^(−t/T). BackPoW uses this Poisson relation instead of a naive linear estimate. For this pair: daily chance 7.4e-06%, yearly chance 0.0027%.

BackPoW computes this from live network difficulty using a Poisson block-discovery model.
Is SHA-256 ASIC-resistant, and where does the Bitaxe Ultra stand?
SHA-256 is an ASIC-dominated algorithm. The Bitaxe Ultra delivers 498.85 GH/s (#22 of 22 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 on Bitcoin?
At 15 W, operating a Bitaxe Ultra 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 0.054 USD/kWh.
What happens if my Bitaxe Ultra 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 110,741 yr, accumulating roughly 1,004,734 USD in power costs.
