Description
Why the Bitaxe — The Open Source Bitcoin Miner Built for Solo Mining
The Bitaxe is the most popular open-source Bitcoin miner on the market — a single-chip solo bitcoin miner that puts real ASIC hashpower on your desk for under $200 CAD. Whether you choose the Supra or Gamma, you are running the same silicon that powers industrial Antminer fleets, hacked down for home miners by D-Central Technologies, a pioneer in the Bitaxe ecosystem since the early days of the OSMU movement.- True Solo Mining, No Middlemen — Run your own ASIC miner pointed at the Bitcoin network. No pool politics, no custodial risk. If your Bitaxe finds a block, the entire 3.125 BTC reward goes straight to your wallet. Bitaxe devices have confirmed multiple solo block finds, with combined payouts exceeding $1 million USD.
- 100% Open-Source Hardware — Every schematic, every line of firmware, fully public — firmware under GPL-3.0, hardware under CERN-OHL-S. You own the hardware and the code. Audit it, modify it, improve it. This is Bitcoin mining the way it should be.
- Plug-and-Play in Under 5 Minutes — Connect power, join WiFi, enter your wallet address. AxeOS handles the rest. No Linux terminal, no command line, no mining pool accounts required.
- Silent Desktop Operation — At 35-40 dB, the Bitaxe is quieter than your laptop. Run it 24/7 on your desk, shelf, or nightstand without anyone noticing. Designed for home miners, not data centers.
- Two Generations of ASIC Power — Choose between the Supra (BM1368, 625-775 GH/s) for an efficient entry point, or the Gamma (BM1370, 1.0-1.2 TH/s) for maximum hashrate from a single chip. Both use the same silicon that powers industrial Antminer fleets — hacked down for your desktop.
- Backed by Canada’s Bitcoin Mining Hackers — D-Central Technologies has been in the Bitcoin mining industry since 2016. We created the original Bitaxe Mesh Stand, developed custom heatsinks, and our ASIC repair team has serviced thousands of mining machines. When you buy a Bitaxe from D-Central, you are buying from builders who live and breathe this technology.

Available Models: Supra and Gamma
Both models share the same form factor, case options, and cooling ecosystem. The difference is under the hood — the ASIC chip generation.Bitaxe Supra — BM1368
Built around the BM1368 chip from Bitmain’s 5nm process node (the same generation that powers the Antminer S21). The Supra delivers 625-775 GH/s at approximately 12W — an efficient starting point for solo mining. Lower power draw means lower heat and quieter operation, making it ideal for spaces where every watt matters.Bitaxe Gamma (600 Series) — BM1370
The flagship single-chip Bitaxe. The BM1370 comes from Bitmain’s 5nm process node (the silicon behind the Antminer S21 Pro). It pushes 1.0-1.2 TH/s at ~18W stock for industry-leading ~15 J/TH efficiency (up to ~21W overclocked). If you want maximum hashrate from a single open-source ASIC chip, the Gamma is the clear choice. With overclocking and upgraded cooling, the Gamma can push well beyond 1.2 TH/s.Cooling Options

How much does a Bitaxe earn per day?
In pool mining mode, a Bitaxe Gamma earns approximately $0.04-$0.05 CAD/day in BTC before electricity. But most Bitaxe owners solo mine — meaning you earn nothing day-to-day unless your miner finds a full block, which pays the entire 3.125 BTC block reward. At current prices, that is over $300,000 CAD. The Bitaxe is a lottery miner: the ticket costs about $2-4/month in electricity.What are the chances of finding a Bitcoin block?
A Bitaxe Gamma at 1.2 TH/s has roughly a 1-in-3.5-million chance per day of finding a block against the current network. That translates to approximately 0.01% probability over a full year. Despite these long odds, Bitaxe devices have confirmed multiple solo block finds, with combined payouts exceeding $1 million USD. Every hash has an equal, independent chance — and every hash strengthens the decentralization of the Bitcoin network.What power supply does the Bitaxe need?
Both the Supra and Gamma require a 5V power supply with a 2.1/5.5mm barrel connector. A 5V/6A (30W) PSU is recommended for stock operation. For overclocking, use a 5V/8A (40W+) PSU. Never use a 12V power supply on a Bitaxe — it will destroy the hardware instantly. D-Central sells compatible power supplies for both North American and European plugs.Bitaxe Gamma vs Supra — which should I buy?
The Gamma (BM1370, 1.0-1.2 TH/s, 15 J/TH) is the best all-around choice with the highest hashrate and best efficiency from a single chip. The Supra (BM1368, 625-775 GH/s, 17 J/TH) draws less power and runs cooler — great if you want lower electricity costs or plan to run multiple units. For new solo miners, the Gamma is the clear recommendation.Can I overclock my Bitaxe?
Yes. AxeOS supports overclocking through the web interface. A Bitaxe Gamma can be pushed from stock 1.2 TH/s to 1.5-2+ TH/s by increasing the ASIC frequency and core voltage. Requirements: upgraded cooling (Ice Cooler Tower or Argon THRML), a robust 5V/8A PSU, and temperature monitoring (keep below 75°C). Increase frequency in 25 MHz steps, waiting 15-20 minutes between changes for stability. Or skip the DIY and get the Modern Minibit Gamma — pre-overclocked and ready to mine at nearly 2 TH/s.Which mining pool should I use?
For solo mining (recommended for Bitaxe), the two main options are Solo CKPool (solo.ckpool.org) — 2% fee, robust infrastructure, 14+ confirmed block finds — and Public Pool (web.public-pool.io) — fee-free and self-hostable. For pool mining with predictable small payouts, Ocean and Braiins are solid choices. Solo mining is the primary use case for the Bitaxe — every hash counts.How do I update AxeOS firmware?
Open your Bitaxe’s AxeOS web interface in a browser (type the device’s IP address into the address bar). Go to Settings, scroll to “Latest Releases,” and upload the new firmware file. The update takes about 60 seconds. Always use official firmware from the AxeOS GitHub releases page. If your web interface is unreachable, use the Bitaxe Web Flasher to factory-reset and reflash.Is the Bitaxe worth it?
If you are looking for daily profit, the Bitaxe is not the right tool. But if you understand it as a lottery ticket that costs $2-4/month in electricity with a chance at 3.125 BTC, a way to support Bitcoin decentralization by running your own miner, a hands-on tool for learning how mining works, and a beautifully engineered piece of open-source hardware — then absolutely. Multiple solo miners have won full blocks worth $250,000+ USD with devices exactly like this one.My Bitaxe is showing 0 hashrate — what do I do?
Common fixes: (1) Confirm your WiFi is 2.4 GHz — the Bitaxe does not connect to 5 GHz networks. (2) Move closer to your router if signal is weak. (3) Check that your mining pool URL and port are entered correctly in AxeOS. (4) Try a different USB/power supply — underpowered PSUs cause instability. (5) Restart the Bitaxe and your router. If the issue persists, reflash the firmware using the Bitaxe Web Flasher. Still stuck? D-Central’s repair team is here to help.Why buy from D-Central?

Got my first two of three and got to say they work great. One I replaced the plastic clips holding the heatsink with tiny nuts and bolts. Replaced the stock fan with 40x40x20mm noctua fans and they run great! I have a hard time getting decent uptime because I keep changing settings, but they ran for 4 days no issue last weekend, hashing away at 1.2Th/s each.
Part of the fun is modding it to make it run better and faster, adding heatsinks, better paste, cooler, fans, power etc.
If you love tinkering, overclocking and miss mining from the old GPU days, this is a nice project to play with.
And there is always that slim chance of finding a BTC block, or BCH if you want to go down that route!
