Looking for the most affordable Bitcoin ASIC Miner

I’m trying to put together some info for a thread about the cheapest Bitcoin ASIC miner available and its KWH consumption. It’d be great if you could share details about a model that’s suitable for apartment use too.

You need to narrow down your question. Miners range from ones giving ~500GHS pulling only 15W that cost just $40 to those producing far more speed, pull more power with a far higher price.

I would argue the 1tb bitaxe is good.

The ones from ~ 6-10THS, pulling a minimum 50W, that cost within $100-$200

Too small, waste of energy. The ones from ~ 6-10THS, pulling a minimum 50W, that cost within $100-$200, possible for that range?

No 6 th pulls 50 watts Think 12-15 watts a th. So maybe you can find a 6th unit at  85-100 watts ? I do know of any that exist. As for a 10th at 50 watts also does not exist. A 10th at 140 watts maybe. But it will be 850 dollars. https://www.futurebit.io/apollo-3. This is a 13 watt miner. 10-18th And cost way more than you want. Basically your gear simply does not exist.

The cheapest would be a broken antminer S5 that doesn't work and consumes 0 kWh a year. Cheapest is a broad term, cheapest per TH? cheapest entire miner? with no specific information you will not get the correct answer you are looking for. As for running them in the apartment, what is the restriction here? noise? power? space?

Looking at data on https://www.asicminervalue.com/efficiency/sha-256, there's no ASIC that meet your criteria. 50W with 6 TH/s means 8.3TH/s, but most efficient ASIC currently only have 9.5 TH/s. IMO the closest one to what you're looking for is Bitaxe Supra Hex 701. It has 4.2 TH/s with 75W usage. From quick search, it has price range $180-$250 (without other cost).

All information about ASICs is collected on this website. https://www.asicminervalue.com/ The Fluminer T3 (115 Th) and Canaan Avalon Q (90 Th), considered apartment ASICs, significantly outperform industrial ASICs in terms of cost per terahash. They pay for themselves over a long period of time. The cheapest option is to buy a used S19 ASIC for $200 and you will have 90-100 terahash. But this is not an apartment option.

Personally I'd checkout those from GekkoScience https://www.gekkoscience.com/shop/ good prices, excellent quality.

This is decent https://www.gekkoscience.com/product/terminus-a2z-6th/ If he runs at 5th he would likely use 80watts It is $380 This is cheaper https://www.gekkoscience.com/product/gekkoaxe-gt-2xbm1370-solo-miner/ It can do 2.5th and is under 200 But no one makes 6th for 50 watts under 200 here is my under clocked bitaxe from geckoscience I do about 13-15 watts and get about 0.90th I point it at cksolo in hopes of really good luck

I didn't mention, power supply is from a solar panel of 100 watt from not just a single panel. Bitaxe Supra Hex 701 with 4.2 TH/s and 75W mentioned by ABCbits is close to what i am asking. I appreciate everyone contribution to the thread, information gathered.

so will you charge a battery to mine because a 100 watt panel will not run a 75 watt miner well. https://www.gekkoscience.com/product/gekkoaxe-gt-2xbm1370-solo-miner/ this will work much better with a 100 watt panel if you are doing 100 watt panel to charger to battery to power supply to 5volt  miner you do not want to do 50 to 75 watt miner a 30 watt miner like the link above is better. how big is your battery 12v 100 amp or 12v 50 amp

Bitaxe Gamma 601 – Build your own homemade Bitcoin miner I consider such miners useless given the increasing difficulty of Bitcoin mining, but has anyone tried to build this ASIC themselves? If possible, you can get a cheap option without purchasing. It's easier to buy one ASIC, but for several devices it might be more profitable to make it yourself.

You can solder it at home. It has basically about 8 components you put toogether. But it is quite time consuming and prone to errors on first assembling + soldering. You will not save mostly any money because the most expensive part is the hashing chip itself or set of chips and this cost more than half of the miner so basically you are trying to save on few USD.

I don't see any difficulties for an experienced engineer. A beginner would have to buy a soldering station, which wouldn't be cost-effective even for 10 devices. And if I have a soldering station and the chip in that device is the most expensive, then I'll need to find a broken ASIC with several working chips. Then this idea would be profitable.

You are exactly correct and that is how these small miners are made. Just broken machine, respectively broken hash-board is enough. That is how they do it. And yes the idea is profitable. But if you compare that you would have full hash-board of these chips working it is profitable as well and slightly more

Related thread to this post, oneminers dot com is a probable scam mining company. I've seen some people buy the parts separately and assemble manually on either youtube or blog post. But the individual parts could be costly depending on where you live.

S21 ASIC parts are still expensive these days. But there are plenty of S19 series parts available for very little money. Can these devices use 19th-generation chips? It would look more interesting, although it would consume more electricity.

You are right that those are useless from perspective of making you rich. They will not change your life but these home made soldered open ASIC miner platform ASICs can be excellent for educational purposes and experimenting. You can get real hands on real mining of bitcoin that is profitable (few cents, but pofitable) and they have all components of mining. They. have real hashrate and you can solo mine or use pool and it is enought to already have some share from pool.
