BitAxe the cheapest lottery on Earth (and its good for Bitcoin)

[gaelium]

Hey everyone,

Been reading about BitAxe miners lately and figured I'd put together a quick comparison of whats out there right now since I couldnt find a recent one on this board
For anyone who doesnt know, a BitAxe is a small open source ASIC miner that solo mines BTC over wifi. It uses real Bitmain chips, costs between 50 and 250 bucks, and consumes almost nothing.

Here are the main models

BitAxe Ultra (BM1366 chip) : around 500 GH/s, 12-15W, cheapest way to get started
BitAxe Supra (BM1368 chip) : around 700 GH/s, 12W, better efficiency
BitAxe Gamma (BM1370 chip) : around 1.2 TH/s, 15-20W, best bang for the buck imo
BitAxe GT (BM1370 chip) : around 1.5 TH/s, 18W, the Gamma pushed harder
BitAxe Hex (6 chips) : around 3-4 TH/s, 90W, for the serious ones lol



Now lets be real about the odds. A Gamma at 1.2 TH/s against a network doing 700+ EH/s gives you roughly 1 in 1.6 million chance per day of finding a block. Sounds terrible right??
But theres 144 blocks per day and you're paying like 3-4 bucks a month in electricity. If you hit a block thats 3.125 BTC which is over 200k at current prices.

Try finding a lottery ticket with those odds for that price  
But heres the thing thats not talked about enough, decentralization.

Right now BTC mining is concentrated in huge farms in China and the US running machines that cost 100k+.
If millions of people run a little BitAxe at home thats millions of independent mining nodes that nobody can shut down at once.
Even if each one is tiny, together they add real hashrate and more importantly they make the network more resilient.

Thats kind of the whole point Satoshi had in mind when he wrote "one CPU one vote" right?

So yeah its a lottery but its a lottery that costs almost nothing, helps secure Bitcoin, and looks cool on your desk. Theres worse hobbies out there  

Anyone here running one long term? Curious about temperatures and reliability after a few months of 24/7 mining

I  have one online since October 2025.

The 1.1th model

I down clocked to  800gb and lowered the fan to 80%

It basically just runs and runs and runs.

If you buy a 1 chip model just down clock it lower the fan speed and let it run.

I use about 350 watts a day or 7 cents at 20 cent power per kwatt.

So for 73 dollars in power a year I get a shot at every block.

If you believe in btc and do not do this or no mining at all it is a bit selfish.

Folks, do be aware that being an open source design there are many many makers of them with most in China and eastern Europe. Many of the makers seem to have almost zero QC and as a result the miners can fail rather quickly. Follow Phil's advice and don't push them hard if you want them to last.

Lol,  just to clarify: there is no Czechoslovakia since 90s (it's now two separate countries Czechia and Slovakia).

I've bought my units from Spain (think it was from Bitronics) around jan-2025.
Down clocked both freq. and voltage (to be one step under the Default) and both are running sooth.

Thanks for the feedback

Honestly I heard about BitAxe randomly a while ago and thought it was just a gimmick at first but then I started digging and it grew on me, figured I'd share what I found

Good to hear that some of you are running them for months without issues, 8 months non stop is not bad at all.
The downclocking advice makes a lot of sense too, no point burning the chip just for a few extra GH when its a lottery anyway lol.

And yeah the comment about it being selfish not to mine if you believe in BTC hit me, never thought of it that way but its true

For the QC thing thats a fair warning I should have mentioned.
I actually just ordered a Gamma 601 from aliexpress so yeah we'll see what shows up... you never really know with chinese sellers  planning to do some testing when it arrives, max hashrate temps power draw etc.
 
Hoping to get around 1.8 TH/s out of it but if the chip is garbage well ... let's see 

Maybe I should have bought from Bitronics in Spain instead mmm

why run it at high speed it will break.

 800 to 900gh on a down clock fans at 80%

[gaelium]

Yeah no worries I'm not gonna run it at full speed 24/7 thats asking for trouble lol.

But when it arrives I just wanna push it once to see what the chip can actually do, max hashrate and power draw just for my own curiosity.
After that I'll downclock it like you said 800-900 GH/s and let it run quietly
