In the ever-evolving world of cryptocurrency, Bitcoin mining has long been seen as a resource-intensive endeavor—requiring massive rigs, industrial power supplies, and technical know-how. But what if you could start mining Bitcoin (BTC) profitably from your home, without breaking the bank? Enter the Canaan Avalon Nano 3S, a compact, energy-efficient mini Bitcoin miner priced at just $399. This tiny powerhouse is redefining what’s possible for individual miners, especially those interested in solo mining, home-based setups, and contributing directly to the Bitcoin network.
This in-depth guide explores how the Avalon Nano 3S makes profitable Bitcoin mining accessible, its performance metrics, setup process, and real-world mining potential—all while supporting the decentralized ethos of Bitcoin.
What Is the Canaan Avalon Nano 3S?
The Canaan Avalon Nano 3S is a compact ASIC (Application-Specific Integrated Circuit) miner designed specifically for Bitcoin’s SHA-256 proof-of-work algorithm. Unlike traditional mining rigs that fill garages with noise and heat, this device measures just a few inches and plugs directly into a standard USB power source via a USB-C to DC barrel connector.
Despite its size, it delivers a hashrate of 110 GH/s with a power consumption of approximately 28W, making it one of the most efficient small-scale Bitcoin miners on the market. It's not meant to compete with warehouse-sized mining farms—but it is engineered for individuals who want to mine Bitcoin independently, whether solo or in a pool.

Setting Up Your Avalon Nano 3S
Setting up the Avalon Nano 3S is surprisingly simple:
- Power Supply: Use a reliable 12V/3A power adapter (not included). A standard USB-C wall charger may not provide enough stable power.
- Network Connection: Connect the miner to your router via Ethernet using a USB-to-Ethernet adapter (also not included).
- Configuration: Access the miner’s web interface by finding its IP address on your network. Default login credentials are usually
root/root. - Mining Pool or Solo Setup: Input your chosen mining pool’s server address and your Bitcoin wallet address. For solo miners, configure it to point directly to your self-hosted full node.
Once configured, the miner begins hashing immediately. The entire process can take under 15 minutes for tech-savvy users.
Solo Mining vs. Pool Mining: Which Is Right for You?
One of the most compelling features of the Avalon Nano 3S is its flexibility in mining modes.
Pool Mining
- Pros: Steady, predictable income. Rewards are distributed based on contributed hashrate.
- Cons: Requires trust in the pool operator; small miners earn fractions of BTC over time.
Popular pools like CKPool and Braiins Pool support small ASICs like the Nano 3S and offer low or zero fees, maximizing profitability.
Solo Mining
- Pros: Full block rewards (6.25 BTC + transaction fees) if you solve a block. Greater privacy and decentralization benefits.
- Cons: Extremely low probability for small miners due to network difficulty.
While hitting a full block with 110 GH/s is statistically rare, tools like SoloLuck.com can estimate your expected time-to-mine based on current network conditions. Many enthusiasts enjoy the thrill and ideological purity of solo mining—even if profits come slowly.

Mining Efficiency and Profitability Analysis
Let’s break down whether mining with the Avalon Nano 3S is truly profitable.
Key Metrics:
- Hashrate: 110 GH/s
- Power Draw: ~28W
- Power Cost Assumption: $0.10/kWh (average U.S. residential rate)
Using these figures:
- Daily power cost ≈ $0.067
- Estimated daily revenue (as of mid-2025): $0.80–$1.20 depending on BTC price and network difficulty
- Net daily profit: ~$0.75
At this rate, the $399 upfront cost pays for itself in roughly 14–18 months, assuming stable conditions.
But profitability isn’t just about direct returns. The Avalon Nano 3S also runs a full Bitcoin node, allowing users to:
- Validate transactions independently
- Enhance personal security
- Contribute to network decentralization
This dual functionality adds significant value beyond raw mining income.
Performance: Heat and Noise Levels
One major advantage of mini miners like the Nano 3S is their suitability for home environments.
- Noise Level: Barely audible—comparable to a quiet fan or refrigerator hum.
- Heat Output: Minimal. Surface temperature stays below 50°C (122°F) under normal operation.
You can safely place it on a desk, bookshelf, or closet without disturbing household members or requiring special cooling solutions.
Internal Design and Build Quality
A teardown reveals high-quality components and efficient board layout. The device uses advanced chip packaging techniques to maximize thermal dissipation within a constrained space. While not user-upgradable, the build suggests durability and long-term reliability—important for continuous 24/7 operation.
Canaan, as one of the earliest ASIC manufacturers (founded in 2013), brings years of experience to this product line, lending credibility to its engineering claims.
Avalon Nano 3S vs. Previous Models
Compared to its predecessor, the Avalon Nano 3, the Nano 3S offers:
- Higher hashrate (up from 88 GH/s)
- Improved energy efficiency (~0.25 J/GH vs. ~0.32 J/GH)
- Better firmware stability and remote management options
These upgrades make the 3S a clear step forward for hobbyist miners seeking optimal performance per watt.
Should You Buy the Canaan Avalon Nano 3S?
If you're looking for quick riches, this isn’t the device for you. However, if you value:
- Decentralized participation
- Educational value
- Low-noise home mining
- Supporting the Bitcoin network
Then yes—the Avalon Nano 3S is an excellent entry point.
It’s ideal for:
- Crypto newcomers wanting hands-on experience
- Developers running full nodes
- Privacy advocates avoiding third-party custody
- Passive income seekers with low-risk tolerance
And remember: every hash contributes to network security.
Frequently Asked Questions (FAQ)
Can I mine Bitcoin profitably with just one Avalon Nano 3S?
Yes, but profitability depends on electricity costs and BTC price. At $0.10/kWh and current network conditions, you can expect small but consistent daily gains after break-even (~14–18 months).
Does it really run a full Bitcoin node?
Yes! When paired with a Raspberry Pi or similar device running Bitcoin Core, the miner can connect directly to your node, enabling true peer-to-peer mining.
Is solo mining realistic with such low hashrate?
Statistically, solving a full block may take years. However, many users enjoy the philosophical alignment with Bitcoin’s original vision—mining without intermediaries.
How do I track my earnings?
Use pool dashboards (like CKPool) or set up local monitoring tools via SSH access to view real-time stats including accepted shares and estimated payouts.
Do I need additional accessories?
Yes—you’ll need a 12V power adapter and USB-to-Ethernet adapter separately. Consider using a smart plug or watt meter (available on Amazon) to monitor power usage accurately.
Is this suitable for beginners?
Absolutely. The setup is beginner-friendly, especially with online tutorials and community support available across forums and YouTube.
