The NerdQaxe++ Rev 6.1 and Canaan Avalon Nano 3S represent two different philosophies in solo Bitcoin mining. The NerdQaxe++ is built for miners who want maximum hashrate and full control through an open-source web interface. The Avalon Nano 3S? It’s for people who want to plug in a device, open an app, and start mining — while heating their room.
Both are legitimate SHA-256 solo miners. But they target completely different users.
This comparison helps you figure out which camp you’re in.
TL;DR
Buy the NerdQaxe++ if you want the highest hashrate and best block-finding odds in a desktop solo miner. Buy the Avalon Nano 3S if you want the easiest possible setup, app-based control, and a device that doubles as a space heater.

Performance: NerdQaxe++ Takes the Lead
The NerdQaxe++ produces roughly 6 TH/s — about 67% more hashrate than the Avalon Nano 3S’s 3.6 TH/s. Against the current Bitcoin network at approximately 900 EH/s:
NerdQaxe++ at 6 TH/s: Statistical expectation of one block roughly every 340 years. Daily probability of hitting a block: ~0.00081%.
Avalon Nano 3S at 3.6 TH/s: Statistical expectation of one block roughly every 570 years. Daily probability of hitting a block: ~0.00048%.
The NerdQaxe++ gives you about 1.67x better odds. Combined with a lower cost per terahash (~$67 vs ~$83), the NerdQaxe++ is the stronger value proposition if raw mining performance is your priority.
The Heater Angle: Why the Avalon Nano 3S Is Different
Here’s where the Avalon Nano 3S stops being “just” a miner and becomes something genuinely unique.
At 75W, the Nano 3S produces a noticeable amount of heat. Canaan designed the device specifically to double as a room heater. The form factor, airflow design, and thermal output are all intentional. In a small room or home office, the Nano 3S provides real supplemental warmth during cold months.
Think about it this way: if you’re already running a small space heater in winter, that electricity is 100% “wasted” on heat. The Avalon Nano 3S converts that same electricity into heat plus a lottery ticket for 3.125 BTC.
You’re not paying extra for mining — you’re mining as a byproduct of heating your room.
This reframes the entire economics of the device. If the Nano 3S replaces even a portion of your winter heating, its effective mining cost drops toward zero.
The NerdQaxe++ at 80–100W also produces heat, of course. But it wasn’t designed with heating as a feature. There’s no heater mode, no thermal optimization for room warming, and the form factor is built for desk or shelf placement rather than heat distribution.
Setup and User Experience
This is where the two devices diverge most sharply.
Canaan Avalon Nano 3S — App-Based Simplicity:
The Nano 3S connects to your phone via Bluetooth. Download the Canaan app (available on iOS and Android), pair the device, connect it to your WiFi network, enter your Bitcoin address, select a mining pool, and tap “Start.” The app handles everything.
The device also features a built-in color screen that displays real-time hashrate, Bitcoin price, and mining status. No web browser needed. No IP address hunting.
No network configuration.
It’s the closest thing to a plug-and-play mining experience that exists today.
For someone who has never touched a miner, the Nano 3S setup might take 5 minutes with zero frustration.
App-controlled solo Bitcoin miner with 3.6 TH/s hashrate, designed to function as a space heater while mining. Simple Bluetooth setup makes it ideal for first-time miners.
NerdQaxe++ Rev 6.1 — Web Dashboard Control:
The NerdQaxe++ runs AxeOS, accessed through a web browser on your local network. After powering the device on, you connect to its WiFi access point (or plug in an Ethernet cable), navigate to its IP address, and configure settings through the AxeOS dashboard.
AxeOS is clean and well-designed, but it assumes a basic level of comfort with networking concepts. You need to know what an IP address is. You might need to check your router’s DHCP table. The dashboard itself is straightforward, but getting to it requires a few more steps than opening a phone app.
For a technically comfortable user, this is trivial. For someone who breaks into a sweat at the word “router,” the Avalon’s app-based approach will be less stressful.
The trade-off: AxeOS gives you far more control. You can tune frequency, voltage, fan speeds, and pool configurations in ways the Canaan app doesn’t support. Open-source firmware also means community-driven improvements, custom builds, and full transparency about what the device is doing. The Canaan app is simpler but more limited and completely closed-source.

Power and Electricity Costs
| kWh Rate | NerdQaxe++ Daily | NerdQaxe++ Monthly | Nano 3S Daily | Nano 3S Monthly |
|---|---|---|---|---|
| $0.10/kWh | $0.22 | $6.60 | $0.18 | $5.40 |
| $0.15/kWh | $0.33 | $9.90 | $0.27 | $8.10 |
| $0.20/kWh | $0.44 | $13.20 | $0.36 | $10.80 |
Running costs are comparable. The Nano 3S draws slightly less power, saving you $1–2 per month. But remember the heater argument: if the Nano 3S’s heat output replaces another heating source, the electricity cost isn’t incremental — it’s redirected from your heating budget.
Who Should Buy the NerdQaxe++?
- You want the highest hashrate in a desktop form factor. 6 TH/s is currently the best you can get in an open-source solo miner.
- You’re comfortable with basic networking. AxeOS is straightforward, but you should be okay with web interfaces and IP addresses.
- You value open-source firmware. Full transparency, community updates, and the ability to modify your device.
- You want Ethernet reliability. For a device running 24/7, a wired connection is more stable than WiFi.
- Cost per terahash is your primary metric. At ~$67/TH, the NerdQaxe++ offers better mining value.
Who Should Buy the Avalon Nano 3S?
- You want the easiest setup possible. Download an app, pair via Bluetooth, mine. No web dashboards, no networking knowledge required.
- You want a space heater that mines Bitcoin. If you live somewhere cold, the dual-purpose design is genuinely clever.
- You’re buying this for someone else. The app-based setup makes the Nano 3S the best gift miner on the market. Anyone can use it.
- You prefer mobile monitoring. Check your miner’s status from your phone anywhere in your home.
- You like the built-in display. The color screen showing hashrate and BTC price is a nice touch that the NerdQaxe++ lacks.
Our Verdict
These miners aren’t really competing with each other — they’re serving different needs.
The NerdQaxe++ is the performance choice. More hashrate, better efficiency, lower cost per terahash, open-source firmware, and Ethernet connectivity. If you’re optimizing for block-finding probability and you have some technical comfort, it’s the stronger miner.
The Avalon Nano 3S is the lifestyle choice. App control, Bluetooth setup, a color display, and genuine utility as a room heater. If you want a device that mines Bitcoin while warming your home office — and you never want to open a web dashboard — the Nano 3S delivers an experience no other solo miner matches.
Neither choice is wrong.
Pick the one that matches how you actually want to interact with your miner.
