Bitaxe Gamma Review - Solo Mining Bitcoin for $1.80 a Month
When everything else in my home mining operation shut down for the summer - the Nano 3S's, the Nano 3, the Avalon Q - the Bitaxe Gamma stayed on. At roughly $1.80 a month to run, it costs less than a cup of coffee. Here's why it's my favorite miner in the lineup and the only one I run year-round.
Bitaxe Gamma - Specs
What the Bitaxe Gamma actually is
The Bitaxe is an open-source, single-ASIC Bitcoin miner built by the community and made for home enthusiasts. The Gamma variant uses Bitmain's BM1370 chip - the same chip family used in high-end industrial miners - crammed into a small, USB-C powered board. It connects to your network over WiFi and can be pointed at any mining pool or solo pool.
This is not a profitable miner by any standard measure. At 1.2 TH/s, your share of the Bitcoin network hashrate is microscopic. But that's not really the point.
How I have it set up - Umbrel solo mining node
My Bitaxe Gamma is pointed at my own personal Bitcoin node. I run Umbrel OS on a mini PC, and from the Umbrel app store I installed the Bitcoin Node app and the Public Pool app. Public Pool lets you run your own solo mining pool locally, and the Bitaxe connects to it the same way it would connect to any external pool.
What this means is that when my Bitaxe finds a block - and yes, statistically this is an astronomically rare event - the full block reward goes directly to my wallet. No pool cut. No shared payout. Just the full 3.125 BTC.
Will that ever happen? Honestly, probably not in my lifetime at 1.2 TH/s. But someone with a Bitaxe found a block in 2024. People win the lottery. The Bitaxe is my lottery ticket that I run for $1.80 a month.
The math is unfavorable. The attitude is everything. Use the solo mining calculator to see your actual odds at your hashrate. Then decide if that's worth $1.80/month to you. For me it absolutely is - but I went in knowing exactly what I was signing up for.
Noise - genuinely near silent
I have the Bitaxe Gamma on my desk in my home office. It is quieter than my laptop fans. It is quieter than the ambient hum of my monitor. On the rare occasion when I remember it's running, I have to look over and check the LED to confirm. My wife, who successfully evicted a Nano 3S from our bedroom, has never once noticed or mentioned the Bitaxe. That should tell you everything about the noise level.
Open source hardware - a big deal if you care about this
The entire Bitaxe design is open source. The hardware schematics, firmware, and software are all publicly available. This is unusual in the mining industry, which tends to treat everything as proprietary. It also means a strong community of people who tinker with the hardware, improve the firmware, and build variations. If you're the type who likes to understand what your hardware is actually doing, the Bitaxe ecosystem is excellent.
The verdict
What I like
- ~$1.80/month to run - essentially free to operate
- Near completely silent
- USB-C power - no special wiring needed
- Works with personal solo node (Umbrel + Public Pool)
- Fully open source hardware and firmware
- Active, enthusiastic community
- Actually fun - it's the hobby aspect of mining distilled
What to know
- 1.2 TH/s is a tiny fraction of network hashrate
- Solo block find is statistically very unlikely
- Not a profitable miner - this is pure hobby
- WiFi setup can be finicky on some networks
Who should buy one
The Bitaxe Gamma is for people who want to participate in Bitcoin mining at home without spending serious money on electricity or hardware. It's for people who understand they're buying a learning experience and a lottery ticket, not a business. It's for people who think it's genuinely cool to have a tiny open-source device on their desk hashing away at the same proof-of-work problem the entire Bitcoin network is solving.
If that's you, buy one. You won't regret it.
