BitAxe: the most affordable lottery on the planet (and it's a win for Bitcoin)

Hey folks, I've been checking out BitAxe miners lately and thought I'd put together a quick rundown of what’s available since I couldn’t find anything fresh on this forum. For those who aren't familiar, a BitAxe is a compact open-source ASIC miner that mines BTC solo over wifi. It runs on genuine Bitmain chips, priced between 50 and 250 bucks, and it barely uses any power. Here are the key models: BitAxe Ultra (BM1366 chip): about 500 GH/s, 12-15W, the most budget-friendly option to kick things off. BitAxe Supra (BM1368 chip): around 700 GH/s, 12W, offers better efficiency. BitAxe Gamma (BM1370 chip): around 1.2 TH/s, 15-20W, the best value for your money, in my opinion. BitAxe GT (BM1370 chip): roughly 1.5 TH/s, 18W, the Gamma is just pushed further. BitAxe Hex (6 chips): around 3-4 TH/s, 90W, for the serious players, lol. Let’s be honest about the chances here. A Gamma at 1.2 TH/s versus a network that’s over 700 EH/s gives you roughly a 1 in 1.6 million chance daily of hitting a block. Sounds grim, right?? But there are 144 blocks to find each day and you’re only spending about 3-4 bucks a month on power. If you actually find a block, that’s 3.125 BTC, which is over 200k at today’s prices. Good luck finding a lottery ticket with those odds for that price. But here’s the part that doesn’t get enough attention: decentralization. Currently, Bitcoin mining is dominated by massive farms in China and the US using machines that cost over 100k. If millions of folks run a small BitAxe at home, that means millions of independent mining nodes that can’t all be shut down at once. Even if each one is small, together they contribute real hashrate and, more importantly, they enhance the network's resilience.

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 smoothly.

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%

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

There have been a lot of inquiries about BitAxe lately. Since we don't know what thermal paste is used, we immediately replace it with Arctic MX-6 or Arctic MX-7 and forget about it for 1-2 years unless you plan to overclock the chip. 3-4 TH/s today already looks like a very small share and hoping for a profit from this is very optimistic.

this why buying a cheap one and doing the under clock with a lower fan speed is easy peasy. mine is running with no issues since october. will it hit a block i doubt it very much. and honestly is hitting a block going to really change my life a lot no it won’t. hitting ten blocks in ten days would be good and the 30 plus coins would work out for me.

To prevent oneself from being a victim of the miner maker from China, Eastern Europe, etc. Where is the best place to get the BitAxe, because i am working on getting one someday, to practically have the feelings of BTC mining, and who knows, maybe luck will be on my side when the lottery BTC wants to hit. Second. Where can I read to understand the ABC of BTC mining as a non tech savvy?

To purchase I went straight to the source: bitaxe.org ... go to BUY (there is a Vendors list, just select your region) As of 2nd: Try some AI maybe? I found it useful especially on explaining general things, plus you can make a specific questions.

So my aliexpress bitaxe arrived and its actually a 602 not the 601 I ordered but whatever lol. Plugged it in without touching anything and its pulling 1.77 TH/s at 26W stock which is not bad at all Anyone here familiar with the 602 ? Is it supposed to run at that speed or should I still downclock it like the older models ? For Myleschetty asking where to buy, bitaxe.org has a vendor list by region thats probably safer than aliexpress but hey... mine works so far

hard to say how they get those numbers as it uses the 1370 chip a 602 https://www.zeusbtc.com/Asic-Miner/Asic-Miner-Details.asp?ID=4014 a 601 https://www.zeusbtc.com/Asic-Miner/Asic-Miner-Details.asp?ID=3994 if you read the links above:  the 602 is 65 bucks and does 1.5 the 601 is 85 bucks and does 1.2 as to which is better the one that is still working in a year from now. it would be fun to know which one will last a year. my 601 is clocked at 800 gh and has run since October with zero issues. https://solostats.ckpool.org/users/bc1qns96gdmrd024q20kav0x6lrlfg72qg8avu54ug

Yeah it seems to have settled around 1.52 TH/s after a couple hours, the 1.77 was probably just the initial spike. Haven't touched the config at all gonna leave it like this for now and see how long it lasts Interesting that the 602 is cheaper but does more hashrate than the 601, you'd think it would be the other way around lol. I guess we'll find out in a year which chip survives

I run mine at 2.xx th 34w Has a raspberry pi ice tower 4 heat pipe cooler and noctua fan, plus a generic 60mm fan on the back. With a meanwell 5v PSU Been running for months like this without issue. Im finding more and more quality out of these bitaxe/nerdqaxe units then ever before Certain units are problematic, (octaxe for example) But my nerdqaxe++ is a. Rev 5.1 , running 7.5th at 150w artic p9 max fan, stock fan on the back, and a large fan to blow over everything Been running like this for almost 7 months no issue. At the prices of these units (bitaxe gamma 601/602 at $40 plus shipping online and nerds for $200 shipped (rev 6 better version) they are no brainers. The rev 6 nerd units run 6th out the box at 100w. Great stats btw Phil! 292G is great!,

But if you're lucky, the reward will be worth all the effort. This lottery mining is attractive due to its minimal costs: the device, the size of a flash drive, operates silently and uses pennies on electricity.

This thread is basically the exact use case that pushed me to build the calculator I posted about. The downclocking point from philipma1957 is the part I think a lot of people miss. Once you are already in lottery-mining territory, the extra few GH/s or even a few hundred GH/s often does not change the odds enough to justify extra heat, noise, rejects, or board stress. Stability and watts start mattering more than chasing the highest screenshot number. I also think the odds examples get stale fast because difficulty keeps moving. Instead of saving one static Gamma example, I put together a simple calculator where you can change hashrate, difficulty, watts, power cost, pool/service fee, and hardware cost: https://blockoddslabs.com/ Would be interested in feedback from people running these long term. If there is a better default assumption for BitAxe Gamma/Supra/Ultra power draw or a solo-pool fee field I should handle differently, I can adjust it.
