Is the Bitaxe Gamma worth it?+
The Bitaxe Gamma delivers exceptional value for home Bitcoin miners seeking a balance of hashrate, efficiency, and affordability. At 1.2 TH/s with only 17W power consumption and 15 J/TH efficiency, it matches the industrial-grade Antminer S21 Pro's efficiency at a fraction of the cost. While traditional ROI calculations show modest daily earnings of approximately $0.02-$0.05, the real value lies in solo mining potential where a single block find rewards 3.125 BTC plus transaction fees. Multiple Bitaxe miners have won full blocks in 2024 and 2025, proving the "lottery mining" approach delivers life-changing payouts for lucky miners. For Bitcoin enthusiasts who value decentralization, education, and the chance at a massive reward, the Bitaxe Gamma is absolutely worth the investment.
How much money can you make with Bitaxe Gamma?+
Earnings from the Bitaxe Gamma depend on your mining strategy. Pool mining generates approximately $0.05-$0.06 per day per TH/s before fees, translating to roughly $1.50-$2.00 monthly for a single Gamma running at default settings. However, solo mining offers a fundamentally different proposition: while daily predictable income is near zero, hitting a block delivers the full 3.125 BTC reward plus transaction fees, worth approximately $200,000-$300,000 at current prices. The odds of finding a block with a single Bitaxe Gamma are roughly 1 in 4.6 million per day, but real miners have beaten these odds in both 2024 and 2025. Think of it as a perpetual lottery ticket that costs only $2-$4 monthly in electricity.
Who makes the Bitaxe Gamma ASIC chip?+
The Bitaxe Gamma utilizes the BM1370 ASIC chip manufactured by Bitmain, the same 5nm chip found in the industrial Antminer S21 Pro. While Bitmain designs and produces the chip, the Bitaxe itself is an open-source project created by the Open Source Miners United (OSMU) community, originally developed by electrical engineer @skot9000. Since the BM1370 is not sold individually, most chips are harvested directly from Antminer S21 Pro hashboards. Various manufacturers and resellers like Solo Satoshi, DTV Electronics, Altair Technology, and others assemble and sell complete Bitaxe Gamma units, each adding their own quality control, warranties, and sometimes custom enhancements like improved heatsinks or cases.
What is the most powerful Bitaxe?+
The Bitaxe GT currently holds the title as the most powerful single-board Bitaxe, delivering approximately 2.4 TH/s using dual BM1370 chips. For multi-chip configurations, the Bitaxe Supra Hex offers 4.2+ TH/s with six BM1368 chips. The standard Bitaxe Gamma 601/602 produces 1.2 TH/s at stock settings but can be overclocked to reach 1.8-2.0+ TH/s with proper cooling upgrades like the Ice Tower heatsink or Argon THRML cooler. Among single-chip Bitaxe models, the Gamma remains the most powerful and efficient, outperforming the older Supra (600-700 GH/s) and Ultra (400-500 GH/s) models significantly.
How to set up Bitaxe Gamma?+

The included power supplies from Solo Satoshi provides 5V at 6A (30W), offering headroom for stock operation and light overclocking. The device uses a 5.5x2.1mm center-positive barrel jack connector. Critical requirements include stable voltage that doesn't drop below 5V under load, quality construction with over-current and short-circuit protection, and global voltage compatibility (100-240V AC input). For overclocking, upgrade to an industrial-grade power supply like the Mean Well LRS-50-5 (50W). Never use a 12V power supply as incorrect voltage will permanently damage the device. When running multiple Bitaxe units, the Mean Well LRS-350-5 can power up to 6 overclocked Gammas with proper wiring.
Is Bitaxe Gamma profitable?+
Traditional profitability metrics show the Bitaxe Gamma generates approximately $0.02-$0.05 daily profit after electricity costs at typical residential rates, resulting in decades-long theoretical ROI. However, this misses the point of "lottery mining." Solo mining offers binary outcomes: either you earn nothing or you win the entire 3.125 BTC block reward plus transaction fees, worth $200,000-$300,000. Real Bitaxe miners have won multiple blocks in 2024 and 2025, proving the model works. The Bitaxe Gamma consumes only 17W, costing approximately $2-$4 monthly in electricity, far less than typical lottery ticket purchases. Beyond direct profit, miners gain educational value learning about Bitcoin's proof-of-work, support network decentralization, and own a device that may appreciate in value. For those prioritizing guaranteed income over potential jackpots, pool mining on platforms like Ocean or Braiins provides small but consistent satoshi payouts.
How loud is the Bitaxe Gamma?+
With our Dark Horse heatsink, the Bitaxe Gamma operates at approximately 35-40 dB at stock settings, comparable to a quiet library or a desktop computer's idle fan noise.
Can Bitaxe Gamma mine a Bitcoin block?+
Yes, the Bitaxe Gamma can absolutely mine a Bitcoin block, and multiple miners have proven this possible. Confirmed Bitaxe block wins include block #853,742 on July 24, 2024 (mined by a ~500 GH/s Bitaxe), block #887,212 on March 10, 2025 (mined by a 480 GH/s unit worth $258,000), block #889,975 in March 2025 (mined by a stock Bitaxe Gamma at 1.2 TH/s for 3.149 BTC), and multiple additional blocks throughout 2025. While odds for a single Bitaxe Gamma are approximately 1 in 4.6 million per day or 1 in 12,700 per year, every hash submitted is an independent chance at winning. Solo CKPool administrator Con Kolivas noted that total hashpower determines odds, and running multiple devices linearly increases your chances. The beauty of proof-of-work is its permissionless nature: even a tiny miner has a non-zero chance of finding the next block.
What is the difference between Bitaxe Gamma 601 and 602?+
The Bitaxe Gamma 601 and 602 refer to hardware revisions within the Gamma 600 series, with the 602 representing an incremental improvement over the 601. Both models use the same BM1370 ASIC chip and deliver approximately 1.2 TH/s at 15-17W. The 602 revision typically includes refined PCB layouts, improved component placement for better thermal management, and minor electrical optimizations.
What mining pools work with Bitaxe Gamma?+
The Bitaxe Gamma supports any Stratum V1 compatible mining pool through AxeOS. Popular solo mining pools include Public-Pool (public-pool.io, default on most devices, free, no registration) and Solo CKPool (solo.ckpool.org, 2% fee, robust infrastructure, multiple regional servers). For pool mining with regular payouts, options include Ocean Pool (supports DATUM for decentralized block templates), Braiins Pool, and ViaBTC. Configuration requires entering the Stratum Host URL, Port number, and your Bitcoin wallet address in the Stratum User field. Some users run their own mining pool software through Umbrel or Start9 home servers for maximum decentralization. Pool selection depends on your goals: solo pools offer full block rewards with no sharing, while traditional pools provide consistent small payouts based on your hashrate contribution. Geographic proximity affects latency, so choose pools with servers near your location for optimal performance.
How long does Bitaxe Gamma last?+
The Bitaxe Gamma is designed for continuous 24/7 operation with an expected lifespan of 3-7+ years under proper conditions. The BM1370 ASIC chip is built for industrial use in the Antminer S21 Pro and handles extended operation well. Longevity depends on operating temperature (keeping the ASIC below 65°C and voltage regulators below 80°C), power supply quality (stable 5V without voltage sag), dust management (periodic cleaning of heatsink and fan), and avoiding extreme overclocking. The ESP32-S3 microcontroller and other board components are rated for years of continuous use. Common failure points include fan bearing wear (easily replaceable), power supply degradation (solved by using quality PSUs), and thermal paste deterioration (re-application every 6 months to 1 year for overclocked units). The open-source nature means firmware improvements continue indefinitely, and replacement parts remain available.
Does Bitaxe Gamma need internet?+
Yes, the Bitaxe Gamma requires an internet connection to mine Bitcoin, as it must communicate with mining pools or nodes to receive work and submit shares. The device connects via Wi-Fi only (2.4GHz networks, not 5GHz) using its built-in ESP32-S3 microcontroller. No Ethernet port is available on standard Bitaxe Gamma models. Internet bandwidth requirements are minimal, approximately 10-20 KB per minute for pool communication. For initial setup, you connect directly to the Bitaxe's broadcast Wi-Fi network, then configure it to join your home network. Once configured, the Bitaxe operates independently without needing a dedicated computer, only requiring network connectivity and power.
Can I run multiple Bitaxe Gamma miners together?+
Absolutely! Running multiple Bitaxe Gamma miners is a popular strategy to increase solo mining odds linearly. Two Gammas double your chances, three triple them, and so on. Each device operates independently with its own power supply, Wi-Fi connection, and pool configuration. For organized setups, Solo Satoshi offers the Bitaxe Stackable Stand to securely mount multiple units while optimizing airflow. When running multiple units, ensure your Wi-Fi router can handle the connections (typically not an issue), verify your electrical circuit can support combined power draw (minimal concern at 17-20W each), and consider using a shared industrial power supply like the Mean Well LRS-350-5 which can power up to 6 overclocked units. All devices can point to the same wallet address on the same pool. Monitoring multiple Bitaxe units is straightforward through individual web interfaces or community tools that aggregate data. Many enthusiasts start with one Gamma and gradually expand their "farm" after experiencing the satisfaction of contributing to network security.
Can I solo mine with Bitaxe Gamma?+
Yes, solo mining is exactly what the Bitaxe Gamma was designed for, and it remains the most popular way to operate the device. Solo mining, often called "lottery mining," means your Bitaxe submits hashes directly to the Bitcoin network without sharing rewards with other miners. If your device finds a valid block, the entire 3.125 BTC block reward plus transaction fees goes straight to your wallet, currently valued between $200,000 and $300,000. The Bitaxe Gamma ships pre-configured to connect to Public-Pool, a free solo mining pool requiring no registration. Advanced users can maximize decentralization by running their own pool through Umbrel or Start9 on a personal Bitcoin node. Real Bitaxe miners have proven solo mining works, with confirmed block wins including block #853,742 in July 2024, block #887,212 in March 2025 worth $258,000, and block #889,975 also in March 2025 mined by a stock Bitaxe Gamma at 1.2 TH/s.
