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.
