Ghosted by OneMiners - owed thousands.

To be clear, I am making this post in the hopes that a little public social pressure might help OneMiners realize that they need to be talking to their disgruntled customers, and doing the right thing with money owed and not refunded.

Longer story:

  • 31st May we purchased a Z15 420s. It was and still is listed as new and available on the website. https://oneminers.com/collections/zcash-miners/products/antminer-z15-420-kh-s
  • 10 days after order and still no updates on shipping, I contacted them. They said new miners were no-longer available but they had refurbished secondhand units we could have, came with full warranty and were discounted over new.
  • After some frustrating back and forth, and chasing, arguing over discount, trying to understand the condition of the machines, it all getting too hard and me eventually deciding I didn't want the secondhand machine, they sent it to me.
  • 15th July the machine finally arrived. It was battered, missing the cover, and not well package. I fired it up and it appeared to mine okay. But within the first few days we noticed one of the ASIC chains running at odd frequencies, and eventually the miner would just XXX out the whole chain, leaving the machine running at about 2/3 speed.
  • At this point, OneMiners still hadn't issued the refund for accepting the second hand machine, and still haven't. I have emailed them almost every day chasing them for this refund, and they've agreed to it, but have not done anything.
  • We're also left with a second hand machine that while covered by warranty, will cost hundreds of dollars to return, and they will not cover the courier fees. I also do not trust that if they get the machine back, they won't simply ignore me.
  • Finally, as part of the 31st May Order, we also purchased a Z15 Pro 840s as part of the August Batch. When all this started to go so wrong and felt so off, I asked them to cancel this order. They have refused. Instead they've told me (when they were still emailing me) that the August batches would be received by them in September, and likely shipped in late September or October. This was not clear when we bought it. And I now I have serious concerns we will get the machine or our money back here either.

TLDR: Purchased 2 miners from OneMiners. One shipped as a damaged secondhand unit and we were not refunded the difference in price agreed from new. The other August Batch machine is in doubt as they've said August Batch orders won't likely arrive till October.

I want my money back and I want to walk away from all this. They haven't replied to any emails from me in two weeks now, so here we are.

Air flow inside the box

I recently got two miners and decided to build a soundproof enclosure for them, but I still haven’t figured out the airflow.

The enclosure will have two identical miners placed one above the other. How would you design the air intake and exhaust so that there is enough airflow while still maintaining good noise reduction and acoustic insulation?

Thanks for any tips!

Help Nano 3s

Good evening everyone, I need help, the charger of my Nano 3s is dead, I thought about buying the one from MeanWell however I have a problem with the mother cable of the Nano3s since this one has a white cable and I don’t know where to connect it, I wouldn’t want to ruin the transformer just arrived and much less the miner.

Has anyone ever had this problem?

Help

Hey, 17M here and I am new to the whole process of crypto but I am pretty knowledgeable but that’s besides the point. I have just ordered myself a bitaxe miner and I’m not sure if I should run it solo or a pool? if I should do a mining pool I’m not sure to do which one. I’m just confused on what I should do either solo or pool? also what are the payouts for each?

Antminer L9 vs S19 XP Hydro 295T – What’s the best pick over the next 1-1.5 years?

Hey everyone,
I’m currently planning a mining setup to deploy over the next 1 to 1.5 years.
My Setup & Constraints:
Electricity: Solar power plant no cost

Power Supply: 63A panel (~25 kW total capacity on 3-phase, or ~14.5 kW on single-phase).

Because operational costs are zero, my decision comes down strictly to capital expenditure, daily yield, and long-term accumulation over a 12 to 24 month horizon.
I’m weighing two specific deployment options that max out my available power:
Option A: 8x Antminer L9 (Scrypt - LTC / DOGE / BEL)
Total Hashrate: ~132 GH/s – 140 GH/s total

Power Draw: ~27.2 kW total (~3,400W per unit)

Hardware Cost: ~$16,800 ($2,100 per unit)

Strategy: Mine Scrypt (merged mining DOGE + LTC + BEL) to build a massive stack before any potential market expansion. Air-cooled, plug-and-play setup.

Option B: 4x Overclocked Antminer S19 XP Hydro 295T (SHA-256 - Bitcoin)
Total Hashrate: ~1.3 to 1.4 EH/s (1,300–1,400 TH/s total) via custom firmware tuning/overclocking (~330–350 TH/s per unit).

Power Draw: ~24 to 26 kW total (~6,000W–6,500W per overclocked unit).

Hardware Cost: ~$4,400 ($1,100 per unit) + dry cooler/hydro container infrastructure costs.

Strategy: Max out raw BTC terahashes. Cheaper upfront hardware cost with massive Bitcoin accumulation, but requires managing a hydro cooling loop.

The Questions for You:
ROI & Yield: At $0 electricity, does 1.3+ EH/s of raw overclocked BTC hydro power outperform 8x L9s on Scrypt over a 12–18 month horizon?

CapEx: Option B saves over $10k on hardware costs compared to Option A. Is it smarter to put that saved $10k directly into buying spot BTC/DOGE, or should I re-invest it into more miners?

Infrastructure & Reliability: How reliable is pushing 4x Hydro units at 6kW+ each on a 63A connection compared to the simplicity of running air-cooled L9s?

Given $0 power and a 63A limit, which setup would you choose for maximum return over the next 1-2 years?
Looking forward to hearing your insights!

Is eliteclouds reliable?

I'd like to know if it's reliable to invest through this website with the GPU rental service they mention. Could you give me some feedback?
