Bitaxe Solo Mining Setup: Unboxing to First Share Guide

So you’ve got a Bitaxe sitting on your desk and you’re ready to jump into the world of Bitcoin solo mining. Good choice. The Bitaxe isn’t going to make you rich, but it’s probably the most honest introduction to solo mining you can get without spending thousands on an industrial ASIC.

I remember unboxing my first Bitaxe Ultra. Held it in my hand, thinking “this tiny thing is going to mine Bitcoin?” It felt almost ridiculous. But once I got it running and saw my first valid share hit CKPool, something clicked. That’s your hashrate, working against Bitcoin’s difficulty, taking shots at finding a block. Sure, your odds are astronomical, but you’re actually doing it.

This guide walks through the entire setup process for a Bitaxe, from physically connecting the hardware to configuring the firmware and pointing it at a solo mining pool. I’ll also tell you honestly which Bitaxe models make the most sense right now, and which ones you should probably skip.

Understanding What the Bitaxe Actually Is

The Bitaxe is an open-source Bitcoin mining device built around a single ASIC chip. It’s basically a miniaturized version of industrial mining hardware, designed for hobbyists who want to participate in Bitcoin mining without the noise, heat, and power draw of a full-sized ASIC.

Different Bitaxe models use different chips. The Bitaxe Supra uses a BM1366 chip from Bitmain’s S19 series. The Bitaxe Gamma uses a BM1370 from the S21. The older Bitaxe Ultra uses a BM1366 as well, but with slightly different configuration.

Here’s what matters for solo mining: these devices produce between 400 GH/s and 1.2 TH/s depending on the model and how hard you push them. That’s nothing compared to modern mining farms, but it’s enough to submit valid shares to a solo mining pool and technically have a shot at finding a block.

Your odds? Astronomically low. With 1 TH/s, you’re looking at roughly one block every 6,000+ years on average at current difficulty. But the point isn’t guaranteed returns. The point is understanding how Bitcoin mining actually works, running your own hardware, and maybe—just maybe—getting lucky one day.

Bitaxe Models: Which One to Actually Buy

Not all Bitaxe models are created equal. Some deliver better efficiency, some are easier to find, and honestly, some just aren’t worth the money anymore.

Bitaxe Supra (My Top Pick)

The Bitaxe Supra uses the BM1366 chip and delivers around 500-600 GH/s at reasonable power consumption (15-20W). It’s widely available, well-supported in the firmware, and strikes a good balance between performance and efficiency.

If you’re new to Bitaxe mining, start here. The community support is strong, troubleshooting is straightforward, and replacement parts are easy to find if something goes wrong.

Bitaxe Gamma (Best Performance)

The Gamma uses the newer BM1370 chip and can push up to 1.2 TH/s when overclocked. Power consumption goes up to 25-30W, but you’re getting double the hashrate of the Supra.

This is the model to get if you want maximum performance from a Bitaxe. Just know that pushing it hard generates more heat, so you’ll need better cooling—either a larger heatsink or a more aggressive fan setup.

Bitaxe Ultra (Older Generation)

The Ultra was the original high-performance Bitaxe, but it’s been largely replaced by the Supra and Gamma. It delivers similar hashrate to the Supra but with slightly less efficient firmware support.

If you find one cheap, it’s not a bad pickup. But if you’re buying new, skip it and go straight to the Supra.

Stay Away From: Bitaxe Max

The Bitaxe Max uses the older BM1397 chip and maxes out around 400 GH/s. It was fine a couple years ago, but in 2026 it’s just not worth it. You’re paying similar money for significantly less hashrate, and the efficiency isn’t good enough to justify the lower performance.

If someone offers you a Max for dirt cheap (under $50), maybe. Otherwise, skip it.

Bitaxe Solo Mining Setup: Unboxing and Hardware Assembly

When your Bitaxe arrives, you’ll have a small PCB with an ASIC chip, a heatsink, a fan (usually 40mm), and a power connector. Some versions ship fully assembled, others require you to attach the heatsink and fan yourself.

What You Need

• Your Bitaxe board
• A 5V USB-C power supply (minimum 3A, preferably 4A or higher for overclocking)
• Wi-Fi network access (the Bitaxe connects via ESP32 Wi-Fi)
• A computer or phone with a web browser

Most phone chargers won’t cut it. You need a proper power supply that can deliver stable amperage. I’ve seen people try to run a Bitaxe off a cheap 2A charger and wonder why it keeps rebooting. Don’t be that person.

Physical Assembly

If your heatsink isn’t already attached, you’ll need thermal paste. Apply a small amount (about a rice grain) to the center of the ASIC chip, place the heatsink on top, and secure it with the provided screws. Don’t overtighten—you can crack the chip.

Attach the fan to the heatsink. Most Bitaxe fans connect via a 2-pin JST connector on the board. Make sure the fan is blowing air toward the heatsink, not away from it. I’ve seen setups where the fan was mounted backward and the chip was thermal throttling within minutes.

Once everything is secured, connect your USB-C power supply. The Bitaxe should power on immediately, and the fan should start spinning. If the fan doesn’t spin, double-check your connection and make sure your power supply is delivering enough amperage.

Firmware Configuration and Wi-Fi Setup

The Bitaxe runs custom firmware based on ESP-Miner. The device creates its own Wi-Fi access point when it first boots up, which you’ll connect to for initial configuration.

Connecting to the Bitaxe

Power on your Bitaxe and wait about 30 seconds. On your phone or computer, look for a Wi-Fi network named something like Bitaxe_XXXX where XXXX is a unique identifier.

Connect to that network. The password is usually “bitaxe1234” or listed in the documentation that came with your device. Once connected, open a web browser and navigate to 192.168.4.1.

You should see the Bitaxe web interface. It’s a simple dashboard with tabs for Settings, System, and Logs.

Wi-Fi Configuration

Go to the Settings tab and find the Wi-Fi section. Enter your home Wi-Fi network name (SSID) and password. Save the settings and reboot the device.

After the reboot, the Bitaxe will connect to your home network instead of broadcasting its own access point. To find its new IP address, check your router’s DHCP client list or use a network scanner app.

Once you have the IP address, enter it into your browser. You should see the same web interface, but now it’s accessible from your home network.

Updating Firmware

Before configuring mining settings, check if your firmware is up to date. The Bitaxe firmware gets regular updates that improve stability, efficiency, and hashrate.

Go to the System tab and check the current firmware version. Visit the official Bitaxe GitHub or community forums to see if a newer version is available. If so, download the .bin file and upload it through the web interface.

Firmware updates typically take 1-2 minutes. Don’t power off the device during an update or you risk bricking it.

Configuring Your Bitaxe for Solo Bitcoin Mining

Now comes the fun part: pointing your Bitaxe at a solo mining pool and watching it submit shares. You’re not going to point this thing directly at your own Bitcoin node (unless you really want to, in which case check out our guide on how to solo mine Bitcoin by running your own full node).

Most Bitaxe miners use CKPool’s solo mining service. It’s free, reliable, and specifically designed for solo miners. When you find a block, CKPool takes a 0.5% fee and sends the remaining 99.5% of the block reward directly to your wallet.

Getting Your Bitcoin Wallet Address

You need a Bitcoin wallet address where block rewards will be sent if you ever find a block. This should be a wallet you control, not an exchange address.

Hardware wallets are best (Ledger, Trezor), but any non-custodial wallet works. If you’re unsure which wallet to use, check our solo mining wallet guide for recommendations.

Copy your Bitcoin address. You’ll need it for the pool configuration.

CKPool Configuration Settings

In the Bitaxe web interface, go to the Settings tab and find the Pool Configuration section. You’ll need to enter the following:

• Pool URL: solo.ckpool.org
• Port: 3333
• Username: Your Bitcoin wallet address
• Password: x (literally just the letter x, the password doesn’t matter for CKPool)

Double-check your wallet address. If you mistype even one character, any block you find will be sent to the wrong address and you’ll never get it back.

Save the settings and reboot the Bitaxe. After it comes back online, it should start connecting to CKPool and submitting shares.

For a deeper dive into how CKPool works and what happens when you submit shares, see our article on how solo mining pools actually work.

Monitoring Performance and Understanding Shares

Once your Bitaxe is connected to CKPool, the web interface will show live statistics: hashrate, temperature, fan speed, accepted shares, and rejected shares.

What to Watch For

Hashrate: Should be relatively stable. A Bitaxe Supra typically runs at 500-600 GH/s, a Gamma at 800-1200 GH/s depending on settings. If your hashrate is jumping around wildly or dropping to zero, something’s wrong—usually cooling or power supply issues.

Temperature: ASIC chips run hot, but you want to stay under 70°C for long-term stability. If you’re consistently hitting 75°C+, improve your cooling. Add a bigger heatsink, increase fan speed, or point a desk fan at it.

Accepted Shares: This is the number of valid shares your Bitaxe has submitted to CKPool. Each share represents work that met the difficulty threshold. More shares doesn’t mean you’re more likely to find a block (your odds are purely based on hashrate), but it does confirm your device is working correctly.

Rejected Shares: Ideally zero. A rejected share means the work arrived too late or didn’t meet the difficulty. Occasional rejects (1-2%) are normal. If you’re seeing 5%+ rejects, check your network connection and make sure your firmware is up to date.

Best Shares vs Block Shares

You’ll also see a “Best Share” value in the web interface. This is the highest difficulty share your Bitaxe has ever submitted. Bitcoin’s current block difficulty is astronomically high—into the trillions—so your best share will almost certainly never come close to finding an actual block.

For context, at the time I’m writing this, Bitcoin’s difficulty is around 102 trillion. Your Bitaxe might submit shares with difficulty in the millions or low billions. That’s not even 1% of what’s needed to find a block.

But that’s solo mining. You’re playing the longest of long shots, and honestly, that’s part of the appeal.

For a detailed explanation of how difficulty impacts your chances, read our guide on how Bitcoin mining difficulty affects solo miners.

Overclocking and Efficiency Tuning

The Bitaxe firmware allows you to adjust core voltage and frequency to increase hashrate. This is overclocking, and it comes with trade-offs: higher power consumption, more heat, and potentially shorter hardware lifespan.

Should You Overclock?

Depends on your goals. If you’re running the Bitaxe for fun and education, stock settings are fine. If you want to maximize your (still incredibly slim) chances of finding a block, overclocking gets you more hashrate for a relatively small increase in power draw.

On a Bitaxe Supra, you can usually push from 500 GH/s to 600-650 GH/s by increasing the core frequency by 50-100 MHz and slightly bumping the voltage. Power consumption goes from 15W to 20W, which is still negligible.

On a Bitaxe Gamma, you can push from 800 GH/s to 1.2 TH/s, but power consumption jumps from 20W to 30W and heat becomes a real issue. You’ll need better cooling.

How to Overclock Safely

In the Bitaxe web interface, go to Settings and find the Performance section. You’ll see sliders for Core Voltage and Frequency.

Start by increasing frequency in small increments (25-50 MHz). Monitor temperature and hashrate stability. If the device stays under 70°C and hashrate is stable, you can try another small increase.

If temperature exceeds 75°C or the hashrate becomes erratic, back off. You’ve hit the thermal limit.

Increasing voltage gives you more headroom for higher frequencies, but it also increases heat output significantly. I generally don’t recommend voltage adjustments unless you have excellent cooling and you’re comfortable monitoring the device closely.

Realistic Expectations: Power Costs and Block Odds

Let’s talk honestly about what you’re getting into. A Bitaxe is not a profit-generating machine. It’s a learning tool, a conversation piece, and a lottery ticket with some of the worst odds imaginable.

Power Consumption and Electricity Costs

A Bitaxe Supra at stock settings draws about 15-20W. Over a month, that’s 14-18 kWh. At the U.S. average electricity rate of $0.15/kWh, you’re paying about $2-3 per month to run it.

A Bitaxe Gamma running overclocked at 30W costs about $3.50-4 per month.

These are small numbers. You’re not going to blow up your electric bill. But you’re also not making money. Even if Bitcoin is at $66,312 right now, your 600 GH/s isn’t going to mine you any meaningful fraction of a coin through traditional mining.

Your Actual Chances of Finding a Block

With 1 TH/s of hashrate, your expected time to find a Bitcoin block solo is currently over 6,000 years. That’s not an exaggeration. Bitcoin’s total network hashrate is above 700 EH/s (exahashes per second). Your 1 TH/s is 0.00000014% of the network.

Could you get lucky and find a block tomorrow? Technically yes. Probability doesn’t care about averages. Someone with a single Bitaxe could find a block on their first share. But the odds are so low that you shouldn’t ever expect it to happen.

So Why Do It?

Because it’s fun. Because you’re actually participating in Bitcoin mining, not just speculating on price. Because running your own hardware and seeing shares hit the pool is more engaging than watching a number go up on an exchange.

And because there’s something deeply satisfying about knowing that technically, you could find a block. The odds are absurd, but they’re not zero.

If you want to understand what happens when you actually do find a block—and what the rewards look like—read our guide on understanding your solo mining block reward.

Troubleshooting Common Bitaxe Issues

Here are the problems I’ve run into (or seen others hit) most often when setting up a Bitaxe.

Device Won’t Power On

Check your power supply. Most issues trace back to using a phone charger that can’t deliver 3-4A consistently. Get a proper USB-C power supply rated for at least 20W.

Fan Not Spinning

Double-check the fan connector. It’s a small 2-pin JST plug that’s easy to accidentally leave loose. Also make sure your fan is actually functional—I’ve received DOA fans before.

High Rejected Share Rate

Usually a network issue. If you’re seeing more than 2-3% rejects, your Bitaxe isn’t submitting shares fast enough. Check your Wi-Fi signal strength. If the Bitaxe is far from your router, move it closer or add a Wi-Fi extender.

Hashrate Dropping or Unstable

Thermal throttling. Your ASIC is hitting its temperature limit and automatically reducing frequency to cool down. Improve cooling: better heatsink, faster fan, or just better airflow around the device.

Can’t Access Web Interface

Make sure your computer or phone is on the same network as the Bitaxe. If you’re trying to access it remotely, you’ll need to set up port forwarding on your router (not recommended unless you know what you’re doing).

Secure Your Winnings

Finding a solo block means receiving 3.125 BTC directly to your wallet — currently worth over $250,000. That amount should never sit on an exchange.

Two hardware wallets we recommend for solo miners:

Ledger Nano X (~$149) — Industry standard, supports BTC natively
Buy Ledger Nano X

Trezor Model T (~$179) — Open-source firmware, strong community trust

Frequently Asked Questions

How long does it take to see my first share on CKPool?

Depends on your hashrate and the pool’s difficulty setting. With a Bitaxe running at 500-600 GH/s, you should see accepted shares within the first few minutes of connecting. If you’re not seeing shares after 10-15 minutes, check your pool settings and make sure your wallet address is entered correctly.

Can I mine other coins with a Bitaxe?

No. The Bitaxe uses SHA-256 ASIC chips specifically designed for Bitcoin mining. You can technically point it at other SHA-256 coins like Bitcoin Cash, but Bitcoin is the most secure and widely adopted SHA-256 chain. Mining anything else is mostly pointless for a hobby miner.

What happens if I actually find a block?

CKPool will automatically send 99.5% of the block reward (currently 3.125 BTC plus transaction fees) to the Bitcoin wallet address you configured as your username. The remaining 0.5% goes to CKPool as a fee. You’ll also get your name on CKPool’s solo block finder leaderboard, which is pretty cool. But realistically, your odds of ever finding a block with a single Bitaxe are extremely low—we’re talking thousands of years of expected time. For more on what a block reward actually looks like, see our article on understanding solo mining block rewards.

Should I run multiple Bitaxe units to increase my chances?

If you want to, sure. Two Bitaxe Supras give you twice the hashrate and twice the chance of finding a block. But you’re still talking about astronomically low odds. Going from one unit to three or four might cut your expected block time from 6,000 years to 1,500 years, which is still effectively never. That said, some people enjoy running a small farm of mini-miners just for the aesthetic and the learning experience. Just don’t expect meaningful returns.

Is solo mining with a Bitaxe more like a lottery or actual mining?

It’s technically both. Every share you submit is a random attempt at finding a valid block hash. From a mathematical perspective, it’s functionally identical to buying lottery tickets, except the “tickets” are generated by your hardware doing real cryptographic work. Some people call it lottery mining for that reason. We have a whole article breaking down the difference between solo mining and lottery mining if you want to dig deeper into the semantics. Bottom line: with a Bitaxe, you’re playing an extremely long-odds game, but you’re doing it with real mining hardware.
