- Compact miners such as the Bitaxe Gamma and NerdQaxe++ make it easier to explore Bitcoin mining at home with different hardware and power requirements.
- Beginners can start with a hosted solo-mining service, while more experienced users can run their own Bitcoin node for greater control.
- Estimating electricity costs and comparing hardware specifications can help you choose a miner that fits your budget and setup.
- Solo mining offers a hands-on way to learn about Bitcoin’s proof-of-work system, mining hardware, and how blocks are added to the network.
Bitcoin mining is often associated with large facilities filled with powerful computers, but it is also possible to try it from home with a much smaller device. Solo mining lets you connect your own miner to the Bitcoin network and compete with miners around the world to find the next block.
The appeal is simple: if your miner finds a block, you receive the full block reward of 3.125 BTC, plus transaction fees, instead of sharing the reward with other miners. Devices such as the Bitaxe Gamma and NerdQaxe++ have made this option more accessible to hobbyists, although the chances of finding a block with a small miner remain extremely low.
If you are considering solo mining in 2026, it is important to understand how it works, what equipment you need, and how much it costs to run. This article compares popular home miners, explains how to set one up, and looks at the odds and ongoing expenses before you invest.
What Is Bitcoin Solo Mining? Understanding the Lottery
Bitcoin mining uses specialized computers to perform repeated calculations until a miner finds a valid block. Solo mining means competing for that block reward without sharing it through a conventional pool payout system.
This approach is sometimes called lottery mining because a small miner can technically win a block, even though its chances are extremely low.
Pool Mining vs. Solo Mining
The main difference is how mining rewards are distributed.
In conventional pool mining, many miners combine their computing power. When the pool earns rewards, it distributes payments according to its payout method and each participant’s contribution. This generally provides smaller, more frequent payments.
Solo mining works differently. If your miner finds a valid block that the Bitcoin network accepts, you can claim the entire block subsidy and the transaction fees included in that block.
| Feature | Solo Mining | Conventional Pool Mining |
| Reward | Full block reward if successful | Shared according to the pool’s payout rules |
| Payout frequency | Unpredictable | Generally more frequent |
| Income consistency | Very low | More predictable, but not guaranteed |
| Fees | Depends on the setup or service | Depends on the pool |
| Best suited to | Hobbyists and risk-tolerant miners | Miners seeking more regular payouts |
Table 1. The main differences between solo mining and conventional pool mining.
You can solo mine through a service without operating your own mining server. For example, Solo CKPool connects miners to the Bitcoin network without sharing a successful block’s reward among a group of contributing miners. The service advertises a 2% fee on successful block rewards.
Alternatively, you can run your own Bitcoin node and compatible mining software. This gives you more control but requires additional hardware, configuration, and maintenance.
As of October 2026, Bitcoin’s block subsidy is 3.125 BTC, following the April 2024 halving. The winning miner can also claim the block’s transaction fees. According to Bitcoin.org’s halving guide, the subsidy will decrease again at the next halving, currently expected around 2028.
The Reality of Solo Mining Odds
A miner’s chances depend on its hashrate, which measures how many hashes it can calculate each second, relative to the total hashrate of the Bitcoin network.
A small home miner might produce a few terahashes per second (TH/s). The Bitcoin network operates at a scale measured in exahashes per second (EH/s), with one exahash equal to one billion terahashes.
The following estimates illustrate the difference. They assume a network hashrate of 900 EH/s, 144 blocks mined per day, and continuous operation.
The network figure is an example, not a live measurement.
| Miner Hashrate | Approximate Average Time to Find a Block |
| 1.2 TH/s | ≈14,200 years |
| 4.8 TH/s | ≈3,550 years |
| 12 TH/s | ≈1,420 years |
| 90 TH/s | ≈190 years |
Table 2. Illustrative solo-mining odds based on a 900 EH/s network hashrate. Actual odds change with network conditions.
These estimates are averages, not waiting periods. A small miner could find a block much sooner, but it could also run for its entire useful life without finding one.
This is why solo mining is often described as lottery mining. A miner’s low hashrate doesn’t make finding a block impossible, but it makes the probability very small. Buying a device should not be treated as a reliable way to earn Bitcoin.
The Best Solo Bitcoin Miners for 2026
Bitcoin mining requires hardware designed for the SHA-256 algorithm. Most small solo miners are compact ASIC devices built for experimentation, while larger machines offer more hashrate at the cost of higher electricity consumption, heat, and noise.
The following comparison includes representative models from the Bitaxe, NerdMiner and Canaan Avalon ranges. Prices are indicative and can vary by retailer, hardware revision, shipping, and taxes.
The Bitaxe Series
The Bitaxe project develops open-source Bitcoin mining hardware designed for compact, low-power operation. Its devices are popular with enthusiasts who want to experiment with mining without investing in a large ASIC.
The Bitaxe Gamma 601 uses a single ASIC chip and typically produces around 1.0–1.2 TH/s while drawing roughly 17–20 W. Some listings price it below $105, making it an accessible starting point for a home mining experiment.
The Bitaxe Touch offers a display-focused design for users who prefer a more visible interface. It is a more premium option, with prices depending on the version and seller. Check the manufacturer’s or seller’s current listing before comparing it with the Gamma.
Both options are designed primarily for low-power experimentation. Their electricity costs are modest, but their low hashrate means that finding a Bitcoin block remains highly unlikely.
The NerdMiner Ecosystem
The NerdMiner ecosystem includes devices with multiple ASIC chips, allowing them to produce more hashrate than many single-chip miners.
The NerdQaxe++ Rev 7 is rated at approximately 4.8 TH/s, with a suggested price around $289. At this level, it offers more computing power than a Bitaxe Gamma, although the expected waiting time for a block remains extremely long.
The NerdOCTAxe Rev 3.1 Hydro is a higher-hashrate option rated at approximately 12 TH/s and 240 W in the configuration described in the proposed hardware list. Prices vary by seller and cooling configuration, so check current listings before buying.
Hydro-cooled hardware requires particular attention to the included cooling system and installation requirements. Before buying, confirm whether the price includes all necessary components and whether the power and cooling figures match the exact revision.
These miners can make a home setup more capable, but extra hashrate doesn’t guarantee a payout. Their main appeal remains the opportunity to experiment with Bitcoin mining at home.
Mid-Tier Home Miners
Users with more room, better ventilation, and a higher electricity budget can consider larger devices from Canaan’s Avalon range.
The Canaan Avalon Nano 3S is rated at 6 TH/s with power consumption around 140 W. Its price depends on the seller and current availability. It is still relatively compact, but it draws more power than the Bitaxe Gamma and produces more heat.
The Avalon Q offers substantially more computing power, with advertised specifications of approximately 90 TH/s and 1,674 W. It is a different class of home miner and requires more attention to electrical capacity, airflow, and noise. Its price also varies by seller and package.
Canaan’s product specifications are available through its official website. Check the exact model and current listing before buying, as specifications and prices can change.
A stronger miner improves the statistical chance of finding a block, but even a 90 TH/s device remains small compared with the total Bitcoin network. Higher power consumption also means that operating costs can become a major consideration.
How to Set Up Your Solo Miner Step by Step
Setting up a solo miner involves connecting the hardware, choosing how to access the Bitcoin network, and configuring a payout address. Most beginners can start with a hosted service, while more experienced users can run their own node and mining software.
Step 1: Connect to Power and Wi-Fi
Place your miner on a stable surface with enough space for air to circulate around the device. Connect the manufacturer-specified power supply, then follow the setup instructions to connect it to your home Wi-Fi network.
Choose a power supply with sufficient capacity for continuous operation. A common planning guideline is to leave around 20% headroom rather than run a power supply at its full rated output continuously. This is not a universal rule for every device, so follow the manufacturer’s electrical requirements.
A stable internet connection helps the miner receive new work and submit shares. Wi-Fi is sufficient for many small miners, while Ethernet may be useful if the device supports it and your network connection is unreliable.
After startup, open the miner’s local interface and check its hashrate, temperature, and connection status. Make sure the device remains within its specified operating range.
Step 2: Choose Your Setup: Node or Solo-Mining Service
There are two main ways to connect a miner to Bitcoin mining infrastructure.
Option A: Use a Hosted Solo-Mining Service
A hosted service is generally the easiest option for beginners because it provides the mining endpoint and handles the connection to the Bitcoin network.
With Solo CKPool, the service’s published configuration uses:
- Server: stratum.ckpool.org
- Port: 3333
- Username: Your Bitcoin payout address
- Password: x or another accepted value, following the service’s instructions
Enter these details into your miner’s pool configuration, save the settings, and check whether the device connects and submits shares. Solo CKPool advertises a 2% fee on a successful block reward, so review its current terms before connecting.
Option B: Run your own node and mining software
Advanced users can operate a Bitcoin node through a platform such as Umbrel or Start9’s StartOS. A node independently verifies blockchain data and connects to the Bitcoin network.
However, running a node alone does not automatically provide a complete mining setup. You also need compatible mining software that creates or distributes work to your device.
On Umbrel, Public Pool is an open-source solo-mining application designed to work with your own Bitcoin node. After installation, follow its instructions and enter the Stratum connection details provided by the application in your miner’s settings.
This approach offers more control over your mining operation, but it requires a synchronized node, compatible software, and ongoing maintenance. If you are new to Bitcoin nodes, start with the service option and consider a self-hosted setup after you understand the basics.
Step 3: Enter Your Bitcoin Wallet Address
Your miner needs a valid Bitcoin payout address so that a successful block reward can be directed to a wallet you control.
A self-custody wallet is a practical choice because you control the keys needed to spend the Bitcoin. Create or select a wallet, back up its recovery information securely, and copy the receiving address into the miner’s configuration.
For Solo CKPool, the payout address is entered as the username. Other services and self-hosted software may use different configuration fields, so follow the relevant instructions.
Never enter your wallet’s recovery phrase or private key into a miner’s configuration page. A payout address is public information and is all the miner should need for this purpose.
Double-check the address before saving the settings. If your miner finds a valid block, the block’s payout information determines where the reward goes.
Managing Solo-Mining Costs and Expectations
The cost of solo mining includes hardware, electricity, cooling, maintenance, and any fees charged by a mining service. Before buying a device, estimate the running cost and decide how much you are comfortable spending without receiving a reward.
Electricity Consumption
Electricity is one of the main recurring expenses. You can estimate the monthly cost with this formula:
Monthly cost = Power in kW × Hours per day × Days per month × Electricity rate per kWh
For example, a 12 TH/s NerdOCTAxe running at 240 W uses 0.24 kW. At 24 hours per day for 30 days, it consumes 172.8 kWh.
At $0.12 per kWh, the monthly electricity cost is approximately $20.74.
A smaller Bitaxe can cost roughly $1 to $2 per month to run at this electricity rate. However, these figures cover only the miner’s electricity use. They exclude the purchase price, network equipment, additional cooling, shipping, taxes, and possible repairs.
Use your actual electricity rate when calculating costs. If your local rate is higher, your monthly bill will increase accordingly.
Maintenance
Home miners need regular checks to keep operating safely and consistently.
Clean dust from the fan, heatsink, and ventilation openings when needed. A monthly inspection is a reasonable starting point, although dusty rooms may require more frequent cleaning. If you use compressed air, switch off and unplug the miner first, then follow the manufacturer’s cleaning instructions.
Keep the device in a well-ventilated area and avoid blocking its airflow. Larger ASICs produce more heat and noise, so choose a location that can handle continuous operation without affecting your home’s comfort or safety.
Check the power supply and cables for damage or unusual heat. Use the specified adapter, avoid overloaded extension leads, and make sure the electrical circuit can support the device. For higher-power miners, seek qualified help if you are unsure about your electrical setup.
Finally, protect your wallet recovery phrase and keep your mining software updated. Download software only from trusted sources, and do not share private keys or recovery information with a mining service or support representative.
Final Thoughts
Bitcoin solo mining can be a useful way to learn about proof-of-work and experiment with mining hardware at home. It suits hobbyists who can afford the equipment and electricity without expecting a payout. It is not a good fit for anyone who needs predictable income or expects a small miner to recoup its purchase price through block rewards. The main risk is spending more on hardware and electricity than the experience is worth to you. For more background on Bitcoin, explore our Bitcoin Hub.
Frequently Asked Questions
Still have questions about Bitcoin solo mining? These answers cover the costs, hardware, and potential rewards to consider before setting up a home miner.
Is Bitcoin Solo Mining Profitable?
Bitcoin solo mining is generally difficult to make profitable with small home miners because their chances of finding a block are extremely low. Hardware costs, electricity bills, and service fees can add up without generating any Bitcoin. It is better suited to hobbyists who want to learn about mining rather than rely on it for regular income.
How Long Does It Take to Mine 1 Bitcoin Solo?
There is no fixed time to mine 1 BTC through solo mining. A successful miner receives the block subsidy and transaction fees, but finding a block depends on its hashrate relative to the total Bitcoin network hashrate. A small miner could operate for years without finding a block, while a successful block can earn more than 1 BTC at the current subsidy.
Can You Mine Bitcoin at Home With a Small Miner?
Yes. Devices such as the Bitaxe Gamma and NerdQaxe++ allow users to experiment with Bitcoin mining at home. They need a compatible power supply, an internet connection, and a mining configuration. However, their relatively low hashrates make finding a Bitcoin block unlikely.
Is Solo Mining Better Than Pool Mining?
It depends on your goal. Solo mining offers the chance to receive the full block reward if your miner finds a valid block, but payouts are unpredictable. Pool mining combines computing power from multiple miners and typically provides smaller, more frequent payments. Pool mining may suit those seeking more regular rewards, while solo mining is often better for experimentation.
