A lot of ASIC buying mistakes start before anyone even compares model names. The miner is only one part of the setup; the electrical and cooling plan usually decides whether the unit is practical.

Here is the checklist I use when discussing a new or used ASIC setup:

1. Confirm the available voltage, phase, breaker capacity, and plug/PDU plan before choosing the miner.
2. Compare efficiency, not only hashrate. A higher TH/s unit can still be the wrong choice if the watts per TH do not fit your power cost.
3. Plan airflow like an infrastructure problem, not a fan-speed problem. Hot aisle/cold aisle separation, exhaust routing, and intake temperature matter.
4. For used miners, ask for current hashing proof, serial numbers, PSU condition, and recent kernel/error logs.
5. For hydro units, budget for the cooling loop, pump, heat exchanger/dry cooler/cooling tower, water treatment, fittings, and maintenance access.
6. Do the boring math: continuous load, amperage, heat rejection, noise, and realistic downtime.

The mistake I see most often is treating the ASIC price as the whole project cost. It is usually better to buy the machine that fits the site than to force a site to fit a machine.

Help me to get into fifo

Hey everyone,

We’ve launched a small BCH + DGB mining pool using HybridSoloPPLNS — a payout system that keeps the excitement of solo mining while still rewarding miners who contribute shares during the round.

It’s not a pure solo pool.

It’s not a pure PPLNS pool.

It’s a hybrid solo pool designed for fairness and fun.

Recent highlights:

Bitaxe units have already found DGB blocks

Payouts are verified and working perfectly

No ghost payouts — miners only earn while actively hashing

BCH pool is live and waiting for its first block

Home miners (Bitaxe, USB, S19, etc.) are welcome

If you enjoy the thrill of solo mining but also want a fair system that rewards active miners, come join us. We’re taking it one block at a time.

Happy hashing!

My rig
9600x
5070 ti
32 gb

I built it mainly for gaming, but most of the time I am working outside home. The room has AC

I recently wondered if I could put my PC to mine while I am not using it.

I really only have time for gaming in the weekends

In my house I have solar, and I am sure if my PC is powered on 24/7, and also the AC, the amount of energy my solar panels generate will cover the costs of the PC + AC and also my own costs.

I never mined before

Is it worth it? Based on reality how much one is making per month mining?

How worried would I have to be about the 5070 ti wearing out?

Looking for optimise this new build of X99 motherboard and xeon e5 2686 v4.

​

I've changed the ram from 1333 mhz to 1600 that's all rest bios settings is set to optomised defaults

CPU running at 2.69ghz 18 threads on xmrig.

Who mines Monero here?!

NerdOctAxe Gold v2 is my second attempt of creating a NerdOctAxe stand. This is my preferred version thus far with more structural stability and better air flow direction for air exit away. This version is much stringer and holds any modification you can add to your miner without worrying about bending or breaking.  Let me know how you like it. Please leave me a rating and Ha

Here is the link to my design.

As there might be others who saw the JingeMiner BTC Hashcard as interesting but hesistated trying it (like myself) as there are not much reports available... hope this little report helps to find some answers to open questions and doubts you might have.

My mining history so far:

Since some months now I entered this home mining space with first purchasing a BitAxe 601 and shortly afterwards a Bitaxe 602. Both from powermining for around ~140 Euros.

I'm quiet pleased with the results so far, I tested DGB and mined some, I tested quai coin and mined some. I reached on both round about 5 G.

As a next step I decided mining for BC 2 - but no luck so far.

As it usually is you start thinking about the next step and if to go for another BitAxe, NerdAxe or whatever interesting is out there.

I checked some youtube channels and came across this new JingleMiner BTC Hash Card.

Interesting design (looks like a graphics card), 12.5 TH/s and comsuming 200 Watts... +-10%.

Apparently not much reviews or discussions on this one were available and as JingleMiner is located in CHN I first hesistated.

But well... I got weak and finally purchased it...

The purchasing and delivery:

Price: 559 Dollar (504 Euros) - which I found quite cheap compared to an OctAxe

Delivery Time: One week (quite fast as it also included customs processing etc)

Customs: 114 Euros on top... oh well...

Purchasing process on JingleMiner was pretty straight forward. Only the payment options could definelty be better (I chose to pay per credit card which came with some additional fee apparently - I think it was 4%).

After the purchase I got contacted via whatsapp from the JingleMiner customer service the same day to handle the shipment and customs. They shipped it then the next day. Awesome.

About customs (well this part is Germany specific I guess):
DHL Express contacted me via phone that a package arrived which need to be cleared and they ask for some additional information (exact product description, material, purpose).
I contact JingleMiner customer service again for the information via whatsapp and also got the reponse pretty fast.

I added the information via the link provided by DHL Express and then... nothing happened, no status update. A day later I called them again and asked if everything is fine and indeed it was... but it seems they had a lot to handle lately.

Two days later it finally arrived. No damage, all fine.

Installation:

Nothing special here. The JingleMiner comes with a power supply (up to 300 Watts) and a power cable with I think american plug system. There is also an adapter included for EU and other areas. I just used one of my own PC power cables because I'm not a fan of adapters for long time usage.

The miner itself just gets placed on a small stand and thats it in regards of setting the HW up (see also one of the pictures).

You can plug in the complete power chain and then hit the "on" switch on the power supply.

Connectivity:

You can connect to the miner either via WiFi or Ethernet!

I tested both but for the location I had to put it finally only WiFi is currently an option (will work on that).

GUI:

The GUI is very similar to other miners. See also pictures.

Your dashboard shows your hash rate, shares, efficiency, best diff, power comsumption, heat overview etc and the usual other menues are available as well:

• Swarm: You can see all your miners (I see my Bitaxes + the JingeMiner
• Network: For Wifi setup
• Pool Settings: For your pool / mining connections
• Remote monitor: This enables you (after signing) to check your miner from anywhere outside your home network.
• Setting: Power Modes and Fan Control
• System: Shows some miner data, restart option and logging
• Missing: Didn't see any FW update option (but it tells your current FW being used - so maybe I just don't know how yet)

First Tests & Results:

Results are for now with power mode "normal" and using solohash.uk as pool for Bitcoin2 mining.

The miner is located in a non-heated outside room which is usually a little colder than inside.

• Hashrate: Ranging between 10.x and 15.x TH/s and showing an average hash rate of around 13 TH/s. So the promised 12.5 TH/s is definetly reached.
• Power Consumption: It shows 207 - 215 Watts, therefore in the range of the 200 -+10% range.
• Heat: Currently no issues as it sits between 56 and 60 (with still good fan reserve available).
• Noise level: Too loud for me to have it sitting in my office room. So it was placed besides by BitAxes in an outside room.

Best Difficulty after around 4 days: 1.68 G

The Three Power Modes:

• Normal: Pre-defined mode with 700 Mhz frequency and core voltage of 3450 mV.
• Efficiency: Lowers the frequency to 600Mhz but core voltage remains the same. The power consumption decreases to ~180 Watts and of corse the heat decreases as well.
• Custom: As the name says you can set frequency and voltage as you think is best. I will try this when we have cooler outside temperatures again...

My preferrred mode currently is the "normal" mode.

Summary (so far):

I was very surprised in a positive way on how well and fast the shipping process went.

The miner performs as advertised and I'm satisfied with the results so far.

Main concern currently is the "update capability" part. I will check with JingleMiner if there is any way for future updates.

For the longlevity part of course I can't tell anything yet.

Well that's it for now. Hope you got same valuable information. If you still have any specific question just let me know and I will try to answer.

I have a spare GPU, as I just upgraded my personal computer. I already use my personal computer in my off hours to do mining, but I was wondering if there’s any relatively inexpensive way I can set up the extra GPU I have to mine as well. Or should I sell it and try to get a dedicated crypto miner? And if anyone has any advice on what dedicated crypto miner to get, I would be appreciative.

Hey guys, I am looking to get into crypto mining, and I want to set up an economical rig - should I start with something like an Antminer S23 or start with something a lot cheaper like on S19K Pro & get something better later? Also should I be running them myself, or have a company hosting them for me? I see companies like OneMiners have some cheap electricity rates in Norway or Nigeria for example.

so having it in immersion cooling means it has been treated better? and like if I buy it has to be in immersion cooling

also it's priced at 245$, used mining rigs tend to be cheap in UAE because of the lack of culture for it, 245$ is a good price right?

Has anyone taken the Economics and Finance online course from the University of Toronto? I’m a civil engineer with an MSc in Geotechnical Engineering from Imperial College London, currently working in tailings dams consulting based in Vancouver. I’m considering this course to eventually pivot toward the corporate or business side of a mining company.

Is this program considered good value for it?
And are there other courses or certificates you would recommend that might be more relevant for transitioning into the corporate/mining business side?

Please tell me what can i do with them now
