The Ultimate Guide to Bitcoin Solo Mining (2025 Edition)

Solo mining Bitcoin is one of the most exciting yet challenging approaches to earning BTC. Instead of joining a mining pool where rewards are shared, solo miners work independently to find blocks and claim the entire reward. That potential payoff comes with high difficulty — but for some, it’s worth the gamble.

Here’s everything you need to know about solo mining today: the best solo mining pools, tools for calculating your odds, and the top hardware to maximize your chances.

Best Solo Mining Pools

Technically, solo mining means mining entirely alone. But in reality, most solo miners still use specialized “solo mining pools” — servers that connect you directly to the Bitcoin network without splitting rewards.

Here are some of the most trusted options in 2025:

• Solo CKPool A widely respected choice for solo miners. Reliable servers and transparent payouts make it popular among serious miners.🔗 Visit Solo CKPool

• SoloPool.org Offers stable payments, low fees, and robust support. Ideal for miners who want independence with a safety net.🔗 Visit SoloPool.org

• Mining-dutch.NL Offers stable payments in a number of different crypto currencies, low fees, easy switching between which primary coin you are solo mining, lots of merge mining coins to mine at the same time as the primary coin, and robust support. Ideal for miners who want independence with a safety net.

Tools for Calculating Your Odds

Before investing in solo mining, you’ll want to know your chances. These calculators can help:

• SoloChance.com — Enter your hashrate and get a probability of finding a block over time.

• Solo Satoshi Calculator — Gives daily, monthly, and yearly odds and compares them to other scenarios.🔗 Try it here

• SoloLuck — Combines block data with hardware info for deeper analysis.🔗 Check SoloLuck

These tools are invaluable — they help you understand whether solo mining is worth the time, electricity, and hardware investment.

Top 5 ASIC Miners for Solo Mining

The hardware you choose can make or break your solo mining efforts. Here are the top ASIC miners in 2025 and why they stand out:

Top 5 Solo / “Lottery-Style” ASIC Miners (2025)

#	Miner	Hashrate / Power / Efficiency	Key Features / Notes	Strengths / Weaknesses
1	Bitaxe Gamma 601	~1.2 TH/s @ ~17 W (≈ 14–15 J/TH)	Single-chip design (BM1370), built-in WiFi, open firmware (AxeOS), compact form factor	Strengths:  • Exceptional efficiency (~12–15 J/TH) for its class. • Compact, silent, and low-power — perfect for home setups. • Open-source firmware (AxeOS) allows full customization and community support. • Stable performance with low thermal stress. Weaknesses:  • Very low total hashrate — solving a block solo is statistically rare. • Scaling multiple units adds cost and complexity. • Long-term performance decay (~5% over several years). • May produce minor fan noise under heavy load.
2	NerdQaxe++ Hydro	(Vendor listing) “4.8 TH/s, ~60 W, ~15 J/TH”	Multi-chip setup, requires stronger cooling, slightly more complex firmware tuning.	• Harder to manage than the Air cooled variant.
3	NerdMiner / NerdQaxe++	(~3–4 TH/s @ ~45–55 W, est.)	Shares core design with “++ Hydro” version, but with standard air cooling and simpler setup.	Strengths:  • Solid mid-tier solo miner — good compromise between performance and power use. • Easier to manage than the Hydro variant. • Can operate in small clusters for improved odds. • Growing online community for firmware mods. Weaknesses:  • Efficiency not as strong as Bitaxe models. • Cooling can be a limitation under sustained load. • Harder to manage than the Air cooled variant.
4	Nerdaxe Gamma 601	Same as Bitaxe Gamma 601	Essentially a re-branded Bitaxe Gamma — identical core (BM1370), minor firmware or packaging differences.	Strengths:  • Proven, stable design identical to Bitaxe Gamma 601. • Very low power use and high efficiency. • Open-firmware customization options remain available. • Reliable for small-scale home solo mining. Weaknesses:  • Offers no meaningful performance improvement over Bitaxe Gamma. • Possible confusion with firmware versions and branding. • Low absolute hashrate limits block success odds.
5	Lucky Miner LV07	~1 TH/s @ 25 W (≈ 25 J/TH)  🔗 Apexto Mining · asicminervalue.com	Compact WiFi miner with quiet fan, designed for plug-and-play home mining setups.  🔗 asic-miner-profitability.com · ZEUS MINING	Strengths:  • Easy to set up — true plug-and-play experience. • Very quiet (~38 dB), suitable for home or office. • Built-in WiFi and SOLO/pool mode switching. • Lightweight and portable. Weaknesses:  • Lower efficiency (~25 J/TH) compared to Bitaxe or NerdQaxe models. • Tiny chance of block discovery due to 1 TH/s speed. • Limited flexibility — less open firmware. • May run hot in sustained sessions. • Marginal profitability given power cost and BTC price.

 

Analysis & Recommendations

Efficiency matters a lot when your hashrate is small. Every joule per TH counts — Bitaxe Gamma 601’s ~14–15 J/TH remains the benchmark among small solo miners.

Raw hashrate helps, but scaling is expensive. Even going from 1.2 TH/s to 4.8 TH/s (NerdQaxe++ Hydro) increases odds fourfold, but heat, cost, and complexity rise even faster.

Ease of use and firmware support are critical. Miners with open software (like Bitaxe) let you tune performance and get community help — something closed systems like Lucky Miner lack.

Higher hashrates usually mean more heat and maintenance, so keep cooling and noise in mind when scaling multiple units.

Finally, remember: solo mining remains a statistical lottery. Even with the best small ASICs, finding a Bitcoin block solo is rare — but when it happens, it’s a huge win. Good Hunting!
