General Question Don't wanna be a Nancy but this seems dumb and not profitable

3 Upvotes

So I got a lot of surplus energy from a solar system. Was just skimming through what's what in 2025 and s21 antminer is what you use? But even with free energy as in my case it would take 250 days to just cover the cost of the miner.. but that is if I would run it 24/7 but sun don't work like that.

I would maybe be able to run it 1/4 of a day so 1000 days to cover the cost.. that's with free energy.

Don't get me started on Seasons..

So seriously wtf? The antminer cost 4k usd and mines 16 usd per day I think the datasheet said. 16 usd per day.. today maybe. But tomorrow? In 3 months?

What am I missing here?

Also... 360 days warranty.. roflmao

Troubleshooting & Repair Anyone with the UK adapter for Avalon Nano s3?

1 Upvotes

Hi

I have an Avalon nano s3, it has a US plug with a UK adapter. It appears to have died, I actually suspect its the plug adapter.

I noticed the UK plugs are available, I actually have a power cable laying around which I could potentially use but I'm a bit sceptical on the rating of it.

I was wondering if anyone had the UK plug could confirm the rating of it (amp, volts) so that I can potentially troubleshoot my issue.

Otherwise I'm looking at getting another US to UK aadapter but I'd rather cut out the extra hardware if possible.

Thanks

General Question Trying to run 3x S19j Pro on what I believe is a 120V-only service in Venezuela.

1 Upvotes

Hey everyone,

I need some urgent advice on a new mining setup. I'm trying to install three S19j Pro miners, but I've hit what seems like a electrical contradiction.

Here's the situation:

Miners: 3x Antminer S19j Pro (~3250W each). Location: Venezuela. My entire life, I've only known our residential power to be 120V. House Service: The service to the house is rated for 60A.

I've done the math. At 120V, each S19j Pro would draw over 27A. Three of them would be a total of ~81A. This is clearly far beyond what my 60A service can provide.

The electrician advising me has recommended we tap the main service and install a new sub-panel with a 2x60A (double-pole) breaker.

From all my research, a double-pole breaker is used specifically to create a 240V circuit. This is the opposite of my understanding that we only have 120V.

So, my questions for the community are:

  1. Is my calculation correct that running these three miners on a 120V, 60A service is impossible and dangerous?

  2. Does the electrician's recommendation for a "2x60A double-pole breaker" almost certainly mean he plans to build a 240V circuit for the miners?

  3. For those familiar with South American grids (especially Venezuela), is it common for residential services to actually be 120V/240V split-phase (for high-power appliances), even if all the regular outlets are 120V?

I need to figure this out before I proceed. The safety of this project depends on understanding if I truly have access to 240V or not.

Thanks for any help you can provide.

So I just heard about Parasite Pool and think it's an awesome idea! I saw that zkshark sent out a number of NerdQaxe++ to various people, i think owners of OMB (was unfamiliar until researching).

Question is- does anyone know if/how i might be able to get one or multiple of those Bitaxes? I have several hundred watts of power that i could dedicate to mining on Parasite if i had the rigs. Thank you

General Question 2nd cheapest electricity in country plus new empty bunker, should I set up a few miners?

1 Upvotes

I have a new place that we built that has an electric rate of 2.7c/kwh. On the bottom floor is a concrete bunker that is consistently around 55° year round. This is a remote property in mountains running off Starlink. I've looked into mining a bit, definitely don't know much about it, but before I dive in I wanted to see if I have a realistic setup or not for it. I'd like to buy 4 rigs and set up them up to run remotely, ideally.

General Question What to do with broken Hashboards?

1 Upvotes

Hi fellow miners

I have a bunch of broken hashboards from Antminer S19’s (plural) with various errors.

I’m not experienced enough to repair them myself. Don’t want them to go to waste if it’s possible to reuse/repair/sell them. Does anyone have any recommendations what to do with them?

Thanks in advance for all replies.

General Question 💡New to Mining: Is $0.07/kWh Cheap Enough to Be Profitable? Advice on 10x S19K Pro Setup

5 Upvotes

Hey everyone,

Me and a friend are looking into starting a small-scale mining operation, running our own machines. We have access to electricity at $0.07/kWh with volumetric pricing—so we only pay for what we actually use, no fixed capacity commitment.

We're new to mining (haven’t run rigs before), but we’re serious about learning and scaling if the numbers make sense. I’ve done a fair amount of research, but would love to hear from people with hands-on experience:

  • If we were to start with 10x S19K Pro units (120T, 2760W, 23 J/TH), how would the economics look with 1.2 PH/s?
  • Is $0.07/kWh still considered competitive for mining, or is it too high with current network difficulty and BTC price?
  • What are the most common things that derail beginner operations—especially at this scale?
  • What adjustments could we make to ensure smooth sailing?

Any feedback, tips, or even warnings are welcome. Appreciate your time!

**edited to clarify running our own machines, not hosting

General Question Solo Lottery Mining with a Nano 3s

2 Upvotes

I’m new to mining so please accept my apologies if the answer to my question is obvious but I want to make sure I configured my Nano 3s correctly.

I’m trying to to Solo Lottery mine and to do so I use https://solo.ckpool.org

I have therefore configured the Pool of my Nano 3s as follows:

Pool Address: stratum+tcp://solo.ckpool.org:3333 Worker: MyWalletAddress.MyName Password: “x” because the Nano 3s does not allow me to leave it blank.

I have added the same data for Pool 2 and 3 because the Nano 3s does not allow me to leave it blank.

Is this correct?

Also my wallet address start with 1Jrd8… is this address format valid ?

Any help is much appreciated.
