Bitaxe Gamma Review 2025
- Published on
- Reviews
The Bitaxe Gamma is the latest iteration of the Bitaxe series, marking its fifth major revision. This model features the BM1370 ASIC from the Antminer S21 Pro. According to Bitmain, the BM1370 boasts an efficiency of 15 J/TH, and the Bitaxe Gamma comes quite close to achieving that.
The Antminer S21 Pro has a total rated hashrate of 234 TH/s, with three hashboards containing 65 chips each—195 chips in total. The Bitaxe Gamma, in contrast, uses a single BM1370 chip, which translates to roughly 1.2 TH/s per unit. Since the BM1370 is a newly released chip and isn’t yet available for individual purchase, the most reliable source for them is directly from an S21 Pro.
Notably, the BM1370 has a different footprint and pinout compared to previous Bitaxe models, which used chips like the BM1368, BM1366, BM1397, and BM1387.
The Bitaxe Gamma outperforms every other small-scale miner in terms of efficiency. It delivers up to 1.2 TH/s while consuming just 17W, achieving an impressive 15 J/TH efficiency. That’s the same efficiency as the Bitmain Antminer S21 Pro—an industrial-grade miner that costs thousands of dollars (they mount the same chip, the BM 1370). Yet, the Bitaxe Gamma is available for a fraction of that price.
In this review, I’ll be testing the Bitaxe Gamma 601 by DTV Electronics. As official Bitaxe resellers and members of the Open Source Miners United (OSMU), we manufacture a custom version featuring an original case and high-quality assembled components.

Bitaxe Gamma: What It Is?
The Bitaxe Gamma is a compact, single-chip, extremely efficient Bitcoin miner designed for domestic use. Simply keep it powered and connected to a mining pool, and it will generate satoshis in exchange for the electricity it consumes. You can use it to mine in solo mode, or pooled mining mode.
It’s about the size of a Raspberry Pi and uses so little power that the cost is almost negligible—comparable to a light bulb. You can even run it on solar power for zero energy costs.
Unlike industrial miners, the Bitaxe Gamma is quieter and consumes far less electricity while maintaining the same efficiency as high-end models like the Antminer S21 Pro, thanks to its advanced chip. This means you get professional-grade mining performance at a fraction of the cost.
This review focuses on a special version by DTV Electronics, which comes with unique features we’ll explore in detail.
Bitaxe Gamma Main Features
The Bitaxe is an open-source mining project originally developed by @skot9000, an electrical engineer dedicated to Bitcoin and open-source technology.
Open-Source & Community-Driven
@Skot9000 made the entire project freely accessible, sharing the electronic schematics, component sourcing guide, and even the open-source firmware, AxeOS—the official software that powers all Bitaxe models.
One of the biggest advantages of the Bitaxe Gamma is its customizability. Anyone can build, modify, and enhance both the hardware and software. That’s exactly what we’ve done at DTV Electronics with our own custom version of the Bitaxe Gamma.
Form Factor
This special edition of the Bitaxe Gamma by DTV Electronics features a sleek, black enclosure, carefully 3D printed, sanded, and coated for a smooth, professional finish.
- The case optimizes airflow, keeping the internal heatsink cool while maintaining a compact size.
- Unlike open-frame versions, this edition is fully enclosed, making it safer for home use—no exposed electrical parts, reducing the risk of accidents.
- The Bitaxe Gamma and OSMU logos are displayed proudly, reinforcing its high-quality, open-source roots.
- Since this is an OSMU-approved design, it stands apart from low-quality imitations found online.
With built-in Wi-Fi, you only need one power cable—just plug it in, connect to your pool, and start mining.
Hashing Power
The Bitaxe Gamma is powered by a BM1370 ASIC chip from the Bitmain Antminer S21 Pro, one of the most efficient Bitcoin mining chips available.
- Processing Power: ~1.2 TH/s
- Efficiency: ~15 J/TH
- Power Consumption: ~17W
This is the same efficiency as the industrial-grade Antminer S21 Pro, which costs thousands of dollars. The Bitaxe Gamma delivers this level of efficiency at a fraction of the cost.
Power Consumption
The Bitaxe Gamma runs on just 17W, about the same as a standard smartphone charger.
- Runs 24/7 without significantly increasing electricity costs.
- The stock fan runs higher than the Supra or the Ultra due to the fact that the power (and subsequently heating) generated by the chip is far higher.
- Highly efficient, making it one of the most economical small miners available.
Connectivity
The Bitaxe Gamma is designed to work in almost any home setup.
- Wi-Fi (2.4 GHz) built-in for wireless mining.
- No Ethernet port—while Wi-Fi can sometimes have minor packet loss, this isn’t a major concern for a home miner.
- Best used in areas with strong Wi-Fi coverage for a reliable connection.
Mining Pool Compatibility
The Bitaxe Gamma supports Stratum v1, meaning it can connect to most Bitcoin mining pools, including:
- Solo mining & lottery pools like Public Pool, CK Pool & Kano Pool
- OCEAN (public mining)
- Braiins Pool (FPPS payout model)
- DIY mining with DATUM, allowing you to mine your own block
Software
The Bitaxe Gamma runs on AxeOS, the official open-source firmware for Bitaxe miners.
- Core mining software: ESP-Miner
- User interface: AxeOS, constantly updated with OTA (Over-The-Air) updates
- Fully open-source—anyone can contribute, improve, or modify the firmware
Like Bitcoin itself, everything is transparent and verifiable.
Genuine & High-Quality Build
DTV Electronics is an official member of Open Source Miners United (OSMU), a collective that promotes open-source mining solutions as an alternative to closed-source corporate models.
- No cheap knockoffs—our Bitaxe Gamma is built to last.
- Comes with a 12-month warranty—if something goes wrong, we’ve got you covered (overclocking will void the warranty)
- Available for purchase on our website with Bitcoin or through Amazon Prime (Fiat payments) for worldwide shipping.
If you’re looking for a low-cost, energy-efficient, and high-quality Bitcoin miner, the Bitaxe Gamma is one of the best options out there.
Bitaxe Gamma Unboxing
Now for the most important part—what’s inside the box?
The Bitaxe Gamma arrives double-boxed in a sleek DTV Electronics package, designed to highlight the key details of the device.
The front of the box prominently displays the Bitaxe Gamma name, the DTV Electronics logo, and the “Open Source Bitcoin Miner” tagline, reinforcing its fully open-source nature.
In the bottom left corner, you’ll find a note about the included multi-region power supply, ensuring that no matter where you are, you can start mining right away.
Turning the box around, the back panel features a product description and a component diagram, showcasing the internal hardware. This level of attention to detail is a nice touch.
Opening the package, a hard polystyrene shell protects the contents. Many open-source projects ship with minimal packaging, but that’s definitely not the case here—DTV Electronics has put real effort into safeguarding the miner during transit.
What’s Inside the Box?
Lifting the protective panel reveals everything you need to get started:
- User Guide Link – A multi-language manual for setup and troubleshooting.
- Bitaxe Gamma – Fully enclosed, featuring a high-performance cooling system, an ultra-quiet fan, and branded logos.
- Power Supply – A 5A, 25W adapter designed for stable operation.
- Five Plug Adapters – Supports outlets in USA, UK, Europe, Asia, and Oceania.
- 12-Month Warranty – Coverage for any potential issues.
The power adapter is well-built, with a durable, thick cable that remains cool even after continuous use. The five plug adapters make setup easy—just twist clockwise to lock and counterclockwise to remove, eliminating the hassle of choosing the right plug at checkout.
One thing to note: a USB Type-C cable is not included. Most people already have one, as it’s the global standard. The Bitaxe Gamma uses USB-C only for debugging, not for power—despite the USB-C standard supporting well over 240W, while this miner only requires 25W.
It would be interesting to see if future Bitaxe models support PoE+ (802.3at), which can deliver up to 30W (25.5W usable). This would allow both power and network connectivity through a single cable, removing the need for Wi-Fi. Who knows—maybe @skot9000 is already thinking about it?
Bitaxe Gamma Design
The Bitaxe Gamma stands out with a well-designed, fully enclosed polycarbonate shell, offering protection from accidental contact—whether from pets, kids, or just everyday use. But this isn’t just about aesthetics. The enclosure also plays a crucial role in airflow optimization, drawing in cool air from the top and expelling warm air through the side vents.
Efficient Cooling & Temperature Management
During testing in a 21°C room, the Bitaxe Gamma maintained a steady 55-60°C while hashing continuously for days. It has a higher temperature during hashrate compared to less powerful Bitaxes like the Supra. However, that’s far below the 70–90°C range typical of industrial ASIC miners. A lower operating temperature means a longer lifespan, less maintenance, and even potential for stable overclocking.
Side Panel Overview
Right Side (or Left, Depending on Perspective)
- Two exhaust vent strips for warm air release.
- USB Type-C port for debugging.
- Power input for connecting the adapter.
- Sound-absorbing feet that dampen vibrations from the top-mounted fan, making the Gamma nearly silent—only a faint buzz is noticeable up close.
Opposite Side
- Two additional exhaust vents.
- Small opening with two buttons:
- One for flashing the OS.
- One for resetting the device.
- These buttons are tucked away but accessible without tools, though most users won’t need them.
Back Panel & Vertical Setup
The back features the DTV Electronics branding. This side also allows the miner to be placed upright, saving desk space without needing an extra stand. However, vibration damping is reduced in this position, so it may generate slightly more noise compared to when placed flat on its shock-absorbing feet.
Bottom & Front Design
- The bottom panel houses:
- Additional exhaust vents.
- Version number and compliance labels (ROHS, CE).
- Recycling symbol and official Bitaxe seal of approval.
- Website URL and logos.
- The front panel has a stair-step design, sloping from the fan down to the OLED display. Two main stickers add the finishing touch:
- Bitaxe Project logo.
- OSMU (Open Source Miners United) emblem.
Everything about the Bitaxe Gamma reflects smart engineering, from its silent operation to its cooling efficiency, all while maintaining the open-source ethos.
Teardown
If you ever need to clean the device, inspect the internals, or upgrade components, simply remove the feet at the bottom and unscrew the casing. Inside, you’ll notice DTV’s signature deep blue PCB, a unique touch among Bitaxe models. The thermal paste between the heatsink and ASIC comes from a high-quality Swiss manufacturer, ensuring efficient heat transfer. The fan is also top-tier—it can reach high RPM when needed while remaining remarkably quiet.
Bitaxe Gamma First Set Up
Here’s how to get your Bitaxe Gamma up and running.
Getting Ready
Before plugging in the Bitaxe, make sure you have the following:
- Internet Connection – A stable internet connection is required. Fiber or ADSL is ideal, but Starlink and other satellite services should work too. The Bitaxe Gamma only supports 2.4GHz Wi-Fi, so check your router settings. If your 2.4GHz and 5GHz networks share the same SSID, consider separating them.
- Strong Wi-Fi Signal – A weak connection can cause the Bitaxe to drop off the network. If your router is behind multiple walls, consider moving the miner closer or using a Wi-Fi extender.
- Bitcoin Wallet – You’ll need an address to receive mining payouts. Since a Bitaxe earns small amounts daily, Lightning payouts are recommended for frequent withdrawals. If your pool supports BOLT12, Coinos is a solid choice. For solo mining, a standard on-chain Bitcoin address will work.
Once you have these ready, connect the Bitaxe Gamma to power.
First Boot
Every Bitaxe Gamma is tested at DTV before shipping, so it should power up without issues. When you plug it in, you should see:
Connecting to SSID: CPE
Configuration SSID: Bitaxe_XXXX The Bitaxe_XXXX network is the miner’s Wi-Fi setup interface. Connect to it from a laptop or phone, and a setup page should appear.
Connecting to Wi-Fi & Pool
Once connected to the Bitaxe_XXXX network, follow these steps:
- A setup page should open automatically. If not, enter
192.168.4.1in a browser. - From the sidebar on AxeOS, select network and then type your home Wi-Fi and enter the correct SSID and password. Then save and restart the Bitaxe.
- Type in a browser on the same network the IP address of the Bitaxe shown on the Bitaxe display. Configure now the pool settings from the
Settings: - (Optional) Set a fallback pool in case the main one goes down.
- Click Save & Restart—the Bitaxe will reboot and begin mining.
Confirming It’s Working
Once mining starts, the display should show:
- Mining URL – The pool it’s connected to.
- Bitaxe IP – The local IP for AxeOS settings.
- GH/s – Real-time hashing power.
- J/TH – Efficiency metric.
- Best – Highest share difficulty found.
- Temp – ASIC chip temperature.
If everything looks normal, your Bitaxe Gamma is mining successfully. You can then verify everyth
Solo Mining or Pool Mining?
Choosing between solo (lottery) mining and pooled mining is entirely up to the user. As of now, thousands of Bitaxes are hashing on Public Pool, which many refer to as a “solo mining” pool.
However, there’s an important distinction to make. Simply connecting to Public-Pool.io (stratum+tcp://public-pool.io:21496) with a Stratum address, Bitcoin address, and password isn’t truly solo mining. While most people call it solo mining because any block reward goes to a single miner’s address, real solo mining requires creating your own block template. Public Pool does allow this, but it requires running your own Bitcoin node and a Public Pool instance on your network by using a Bitcoin Node like Umbrel—something most users don’t do.
If you opt for pooled mining with OCEAN, for example, you’ll earn proportional to your hashrate. A single Bitaxe won’t make much, but those sats could appreciate over time. Plus, with Lightning payouts via BOLT12 offers, you can receive small daily payouts instead of waiting for a high on-chain withdrawal threshold. You can also create your own blocks with the DATUM protocol, which reduces pool fees. However, when a block is found, the reward is shared among all miners in the pool.
On the other hand, mining on CK Pool or Public Pool in “solo mode” means that if your Bitaxe finds a block (which, according to SoloChance.com, has odds of once every 25,348 years), you receive the entire block reward and subsidy, minus pool fees. It’s like playing the lottery every 10 minutes—exciting, but with slim chances. That said, a Bitaxe has found a block before using CK Pool. One miner with just 3TH of hashrate managed to solve the 290th solo block. So, there is always a chance.
In short, in my opinion, the most pure and best way to use a Bitaxe, while staying true to Bitcoin’s open-source ethos and decentralization, is to create your own block with your own node. This is not just theory—it’s practical and entirely possible.
With Umbrel, you can easily run a Bitcoin node, whether it’s Bitcoin Knots or Bitcoin Core, and set up Public Pool on your own network. By doing this, you compete directly with the entire Bitcoin network to find a block—no third parties, no intermediaries, just you and Bitcoin.
And let’s be clear: every block is always found by a single chip inside a machine—whether it’s a Bitaxe Ultra, an S21 Pro, or any other miner. The size of the miner only determines how often it gets a chance to solve one, but there is always a chance. If you find a block, you get the full reward, and in doing so, you contribute to truly decentralized mining, free from any centralized pool.
Is It Worth Getting a Bitaxe Gamma?
Many people ask, “How much money will I make with a Bitaxe Gamma?” The answer: it depends.
If you mine solo and hit a block, you get the full Bitcoin reward. If you mine in a pool, you earn small but steady payouts. Running multiple Bitaxes increases earnings, but the real value of Bitaxe goes beyond just profit.
Decentralizing Bitcoin Mining
Traditional mining is controlled by a few large, closed-source companies. Bitaxe is open-source and low-cost, allowing anyone to participate, helping distribute hashrate worldwide without expensive mining farms.
Energy-Efficient & Home-Friendly
The Bitaxe Gamma consumes just ~15W of power, about as much as an LED light bulb. It’s easy to run at home without worrying about electricity costs or excessive heat. Plus, setup is simple: just plug it in, connect to Wi-Fi, and start mining.
No Hidden Fees or Hashrate Tax
Unlike some mining firmware that secretly takes a percentage of your hashrate, Bitaxe lets you keep 100% of what you mine.
Great Educational Tool
Mining is Bitcoin’s most physical aspect. Bitaxe provides a hands-on way to learn about Bitcoin, making it ideal for self-education or teaching others, including kids.
Supports Lightning Payouts
Many pools allow Lightning withdrawals, so you can receive small daily Bitcoin payments instead of waiting months or years to hit an on-chain payout threshold.
Bitaxe is more than just a miner—it’s an open-source project that puts mining power back into the hands of individuals, making Bitcoin stronger, more decentralized, and accessible to everyone.

One of the strongest aspects of the Bitaxe Gamma is its efficiency, which is outstanding at just 15 J/TH, even better than the Supra that reaches 17 J/TH, . The economic efficiency (cost per terahash) is quite good at $166/TH, making it more attractive from a pure cost perspective compared to the Bitaxe Supra and other home miners. There is simply isn’t something quite as good as the Gamma at the moment
Interest Ratio (Efficiency × Economic Efficiency) → Lower is better
The Interest Ratio, indicates how “costly” a miner is in terms of power, efficiency and upfront price. Lower values mean better efficiency per dollar spent. Here the Gamma shines at 2490.
- For comparison, the Bitaxe Supra performed much worse at 4250.
Price Weighted Interest Ratio (Efficiency × Economic Efficiency × Price) / 1000 → Lower is better
As the title says, the Price Weighted Interest Ratio is a metric that helps compare Bitcoin miners by considering their efficiency, cost, and overall value. A lower value is better because it means the miner provides better energy and cost efficiency relative to its price. The Gamma scored 498, a quite good number.
- In comparison, the Bitaxe Supra scored 637.5, which is worse than the Gamma.
Lower values are better, meaning the miner offers good efficiency at a reasonable price.
3-Year Possession Cost (Monthly Electric Bill × 36 + Price) → Lower is better
- The Bitaxe Gamma costs just $266 over 3 years.
This is way lower than:
- Canaan Avalon Nano 3: $570
- Antminer S9i: $5446
Overall, while the upfront cost per terahash is high, the efficiency, long-term cost, and decentralization benefits make the Bitaxe Gamma an attractive option—especially for hobbyists and home miners.
Bitaxe Gamma Alternatives
While the Bitaxe Project remains the only open-source Bitcoin mining initiative, its success has inspired larger companies to also introduce small home miners. Here’s how some of them compare:
- Bitaxe Supra – The 3rd generation and most efficient Bitaxe model, delivering 0.6 TH/s at 17 J/TH. It underperforms the Gamma in efficiency but comes at a lower price.
- Canaan Avalon Nano 3S – The second-generation small miner from Canaan, capable of hashing 6 TH/s at 23.3 J/TH. A closed-source alternative with solid performance, much better than the Avalon Nano 3 but with a tag price much higher than the Bitaxe Supra and even of its predecessor.
- Braiins BMM 101 – Offers 1 TH/s at 35 J/TH, but is both less efficient and more expensive (and closed-source, too).
While these alternatives exist, Bitaxe remains unique due to its open-source design, efficiency, and affordability, making it the go-to choice for truly decentralizing Bitcoin mining.
