Topic: The bitaxeHex: Open source Bitcoin miner based on six BM1366 ASICs (Read 227 times)

Well I guess the tiny size appeals. But the chimney can be built for as little as 500 if you use a plain s19. I used the s19xp so it is more efficient and cost more to build.

I am running the xp version pulls 600 watts and does 29th. I CAN go down to 350 watts and 16 th or up to 40th and use 830 watts.

It is hard to justify buying the smaller gear at the price point offerred.

If mining ever gets better the chimney will turn a profit.

There is a way to justify the smaller gear. If mining never gets better and you always solo mine.  Kind of a negative mindset.

tbf you probably wouldn't ever find a block even with an S21

i mean i get it, one has the potential to roi in a decent time period and the other is less likely unless bitcoin moons.

i'm just trying to explain why someone would get the hex over the chimney miner. there are a lot of reasons tbh. for example, there are gonna be people that just buy the chips themselves for $15 each then make a small batch, flip a couple and "get the miner for free".

at the end of the day, the chimney @ $1k is more than 2x the upfront cost of a bitaxe hex and if you don't have free power(almost no one does), then the monthly costs to operate it will be higher & noticeable. we live in an era where people complain about netflix raising the price $2 a month. so something that uses $300 more a month seems like a big difference to many people. the chimney miner will produce a lot more heat and noise as well. the hex just drastically lowers the barrier to entry and limits downside to $400 + electric. for the price of the bitaxe hex and 10¢ electric, you'd have to mine for 12 years to just match what the chimney would cost you in raw dollars.

i'm also guessing the price is gonna come down. you already have luckyminer bitaxe knock offs on aliexpress w/ 2 chips so it's only a matter of time till they copy this and undercut the market.

not hating on the chimney btw i'm just trying to explain the mindset of why someone would buy this over the chimney. ultimately, i think people new to bitcoin will start with stuff like this or the canaan avalon nano 3's then move up to stuff like the chimney or a full sized rig.

And you will likely never hit a block.  And if you mine to a pool at best it earns 18 cents with free power which means 7 years to break even

While the other one set to 20 th costing 1000  earns 1.20 a day with free power taking 3 years to break even.

I USED FREE POWER and a constant 6 cents a th to get those number's.

I have two nanos which are using 200 watts to do 6th on medium. With free power they earn 36 cents a day which is about $360 earned in $1000 days.


Hey I owned tons and tons of small gear medium gear big gear. I WILL LIKELY grab one of these.

my take:

the electric cost for a 60W miner in a year is between $50-$100 @ 10¢-20¢
the electric cost for 400-1000W is $350-$1800 @ 10¢-20¢

the appeal to the 60W miner is that it kind of just feels like a one time fee of $400 and then you're spending less than $5-10 a month in electric, which is not really noticeable to many people.

that and you get a device that'll be efficient for a long time, tbh i wouldn't be surprised to see people mining with these thru the 2032 halving

i'm personally waiting for the 0xAxe which will have 16 chips. there's also someone on the OSMU group working on a solderless ASIC module so eventually there's probably going to be a bitaxe version that's very easy to fix/upgrade.

they seem to be sold out.

I guess people were willing to pay 400 to get the 19 watts a th.


I still don’t understand the mind set of buying these over the chimney miners.

but they are smaller and look better.

Still 1000 usd for a 20th to 37th miner that does 20 watts th
vs 400 usd for 3th miner that does 20 watts a th

It looks quite nice:



I am so happy to see the original Bitaxe growing into such a great hasher....

This is the bitaxeUltra



Having an Open Source miner from software to hardware is fantastic. I never expected it to become actually a bit competitive with the current closed sourced ones, well done!

This bitaxeHex version seems to be the best one out there of the newer version of the original Bitaxe. It seems to have picked the interest of many tinkerers around the world by being open source.

According to them it should be closer to 60+ watts then 50. They have it at 3+TH/s @ 19W/Th

But the price is still a killer. At $400 even if it's only puling less then 1/2 the power of the Avalon Nano 3 its 3x the price.

And yes I know it's not a fair comparison just making the point that if I was looking for another thing to play with $130 + shipping with a power supply is a lot less then $400+ for something that although more efficient is still slower.....

Just my view. Will get one if / when the price drops or people are selling them after they are done playing with them like I did with my Nano.

now the time has finally come and the first of these miners are already being delivered
here the structure of the miner is basically relatively similar to the bitaxeUltra, i.e. 1 esp32 controller and the same chip - bm1366. now comes the difference: instead of one chip, six are now used!
the bitaxeHEX is supposed to have a hash rate of ~3th/s and the power draw should be around 50 watts
