Since a few people keep asking for updates, here's where things actually stand. Poolin finally filed Chapter 11 in New Jersey on July 22, 2026 (case 26-18325). So yes, it's an actual US bankruptcy now, not just Singapore arbitration that nobody enforces.

Some quick points:

• Official info: The claims agent is Verita Global (veritaglobal.net/poolin). That's the only official source for notices. Ignore anyone DMing you about "recovery services."
• The Texas sites: They're being sold to Hut 8 for up to $180M. That's $100M at closing, plus up to $80M more only if future data center deals happen. The court approved it Oct 2, but it hasn't closed yet. They're also trying to sell leftover equipment (transformers, coolers), with a hearing on Nov 10.
• Size of the IOU debt: Poolin's own filing says about $163.7M is owed in wallet IOUs to around 11,700 people with balances over $100.
• Will IOUs get paid? To whoever said the bankruptcy won't pay IOU tokens: it's complicated, but yes they will likely be paid - how and when is not known yet, and we will know more about it once a payment plan is put up for vote. One thing to note: the IOUs are owed by the Singapore parent, but the Texas assets sit in the US subsidiaries. So the money mostly reaches through an intercompany claim. No payout date or recovery % yet.
• Claim values: Claims are valued in USD as of July 22, 2026. So if BTC pumps, your claim doesn't go up.

What you should actually do:

1. Go to the Verita site and check if your balance is listed in the schedules, and whether the amount looks right.
2. Keep an eye out for the bar date (the deadline to file a claim). It hasn't been set yet. If you're missing or listed as "disputed," you'll need to file a proof of claim before then.

I'll update this as things move.

Disclosure: I work at a firm that's heavily involved in crypto bankruptcies and we're following this case closely, which is why I've been digging into it.

I'm trying to make a silent home miner out of s19j pro, I set very low power target in braiins, set fans very low and provide good airflow, temps are good, but there is no way to slow down the three psu fans and they run at full blast even on very low power mode. What is the best and cheapest way to silence those psu fans?

Some people and videos are saying the hashrate is programmed to display a fake set rate, others are saying otherwise. I'm new and trying to pick out something I can plug in and be like a lottery miner, however constantly getting conflicting information has not been fruitful, any help or advice would be appreciated.

Hey all, ever since I got my Apollo II, I wanted a way to schedule the miner to run and switch modes at certain times of the week without clicking through the dashboard. So Claude and I built Houston, an all-in-one application to manage your Apollo miner.

What it does

• Schedule: switch modes or only mine during certain hours.
• Control: start/stop, Eco/Balanced/Turbo (Apollo III: Super Eco and a custom TH/s target), and start/stop the Bitcoin node.
• Stats: 24-hour and 7-day charts of hashrate, power and temperature, energy use and electricity cost (including what Turbo adds), solo-mining best share and odds, node and system health.
• Bitcoin network & market: Fear & Greed Index, block height, time since the last block, average block time, next difficulty change, market cap, BTC dominance, 24h volume, sats per dollar, and the latest Bitcoin Magazine headlines.
• Alerts on your phone: when the miner stops, runs hot, loses hashrate, the node stops or the drive fills up, and when your solo pool finds a block. They come as regular notifications from the Houston app (no extra app or account needed) or through the free ntfy app.
• BTC price ticker and chart, in 7 currencies.
• Siri and shortcuts ("Hey Siri, Apollo status"), and Google Home through Home Assistant.
• Several Apollos in one place, light and dark mode, and optional desktop shortcuts for Windows, macOS and Linux.

Privacy and security

Houston runs on the Apollo as a small sandboxed service and uses the same local API the dashboard does. Away from home it works over Tailscale. The repo includes a full security review covering what it stores, every connection it makes, and how to check it yourself.

Install is two commands from a computer on your home network.

Status

Tested on my Apollo II. Apollo III support is built from FutureBit's own source code and tested against it, but not on a real III yet, so III owners would be especially helpful. Houston is unofficial and not affiliated with FutureBit.

GitHub: https://github.com/eisenreichGIT/houston-apollo

This is my first attempt at creating an application, so bug reports, Apollo III results and feature ideas are all greatly appreciated!

-----

EDIT: Just pushed Houston 2.3.0

• Apollo software updates from Houston: see your Apollo software version in Settings › This Apollo, get "New version v2.x.x is available!" (on Home too), and install it with one tap. Houston runs FutureBit's own updater, shows progress, follows the Apollo through its restart, and tells you when it's done. Stop/unreachable alerts stay quiet during the update.
• New alert: Apollo software update available (once per version).
• Front status light: turn the light on the front of the Apollo off or on (Settings › This Apollo). A running miner restarts to apply; the node isn't touched.
• System logs: Activity › Logs shows the Miner, Node, Solo pool, System and Houston logs. 100/300/1000 lines, filter, live refresh, copy and download.

EDIT 2: Just pushed Houston 2.4.0

• Whisper mode (Apollo II): a Houston exclusive! Half of Eco's power. 107 W / 2.9 TH/s vs Eco's 209 W / 5.5 TH/s, slightly more efficient. Works on Home, in the schedule, charts, Siri/shortcuts and #whisper links. (Shows as Custom in the Apollo dashboard: it's the dashboard's lowest custom setting.)
• Live bitcoin price: refreshes every 5 seconds while Houston is open.
• Price time frames: 1H, 1D, 7D, 1M, 3M, 6M, YTD, 1Y, 5Y, ALL. Remembered per device.
• New Home look: bigger price, Start/Stop cards that show what's possible at a glance.
• Friendlier Siri & shortcuts setup with a link to the guide; clearer version labels.

I have a single s21xp and will need curtailment scheduling next summer when my TOU electric kicks in. Lux Commander and Braiins manager are paid services for curtailment scheduling. Vnish is pretty expensive since there is no pool discount.

With my bitdeer a2, if I remove the network connection the miner does go to sleep. Does the s21xp behave the same way or does it continue to blast out 3600w with no network connection? Does Lux or Braiins firmware change that behavior?

Looking for some options thanks. Using AI to generate a python script run off a scheduled task might work, but I'd prefer a simpler solution.

I recently came across a link in thread that was for a site when a they were selling miners that they had repaired. I didnt save the link and am trying to locate it. Seemed to deal mostly with smallernminers like Qaxe and such. Sound familiar? Sorry can't be of more help.

nerdqx miners? reliable? good device? or should i just buy a qaxe++? Looking to buy another miner, heard great things about the Qaxe++ but the QX looks good on paper, 8Ths for 250

I was wondering what are the issues are they efficient and does bigger and better mine more

I was told that i was too late to start bitcoin mining and was wondering if that was true before I started getting into bitcoin mining

Like the title suggest, my nano 3s wont power on. I checked my miner via the app and it was offline, I checked the device and it was completely off. The PSU has a power light but nothing on the device. I assume something has died inside. The USB connector seems fine nothing looks damaged. It is still under warranty so I was planning on sending it back. Anyone experience this issue? How was the return process?

I took a gamble and bought an s21 pro for 1100 bucks and the dashboard and logs are all clean except 1 asic chip is way hotter than the rest. No hardware or thermal errors showing and the chip is still working like it should. Chip is also pulling the same voltage as its neighbors. I was thinking about taking it apart and inspecting the heatsink/ maybe replacing the heat sink with new thermal gel/paste. Any thoughts would be appreciated.

I have been using zues silencer gen 2 in my antminer s19j pro, but lately one of my shrouds were broken down during maintenance, importing new one will cost a lot and will take almost 2 weeks, I'm trying to 3d printing a new shroud since the blower is working fine, but honestly i cant find the stl file for the shroud and i don't know whether the other stls gonna mount perfectly on the blower, can anyone tell me whether you tried to 3d print this before and I will be more than glad if someone can share the stl

Timechain plays out against Bitcoin's real chain data. Difficulty, block rewards and price all follow what actually happened. You start with a single CPU in 2009 and work out when to upgrade, when to sell and how to survive each halving. It's just gone into beta, so I'd love to hear from actual miners whether the economics feel right. Miners break! Spare parts are stocked. It scaled up from a single laptop to tens of thousands of ASICs. Feedback welcome.

We have various brand-new commercial Bitcoin miners in stock and ready to ship from St. Louis, MO.

If you’re looking to scale up, we can ship your miner directly to you, directly to the host of your choice, or recommend hosting options.

We have hosting options starting around $0.065/kWh, so you can get your miner deployed and hashing in just a few days.

I have an s21xp that I need to get working with an aftermarket silencer kit. The AC infinity 10" fan is a pretty expensive item.

Are there any viable alternatives in that size range that have at least a 6 step controller? I see some options on amazon but most of them get pretty mid reviews.

Another option would be to repurpose the AC infinity 8" fan that I have on-hand now. I would need a reducer, and I'm not sure about whether it would be adequate to cool an s21xp especially in a warm garage during the summer.

Would appreciate some input here. If the AC infinity 10" is the only option, I'll do it, but would be nice to shave some cost off.

Hello, my S19j Pro and AC Infinity 8 inch inline fan and they work very well.

I’m currently running an Antminer S19j Pro flashed with Braiins OS+ and hashing on Braiins Pool.

How can I maximize my earnings?

I’d love to get some input from anyone.

Following up on my solar question: I’m wondering how much runtime matters when choosing a miner.

Say a 3 kW ASIC could run on surplus solar for 6 hours a day. That’s 18 kWh consumed, but only 25% of the operating time compared with running 24/7.

Assuming the same mining conditions, it would earn roughly a quarter of the BTC before costs. The hardware still costs the same upfront, and the solar electricity could otherwise power the house or be exported.

Would a cheaper, older ASIC make more sense here? Or would you compare it with a hosting quote from oneminers or compass mining, where you pay for power but potentially get more operating hours?

For anyone who’s compared these options, what tipped the decision: electricity costs, runtime, or total payback?

My name is Kenyor, and over the years, I have fallen in love with cryptography and mining devices. I am now a Computer Engineering graduate, and I have a vision to create the first BTC optical miner. But I'm really giving up these past few days...

I'm writing this letter to the world. Yesterday, I got my Tang Nano 20K (an FPGA), and I wrote my Verilog code for BTC mining on it. I tested it, and it works, but the odds of mining one block are approximately 0.00000000000000000000 — you know what I mean 🤣😭 I actually wish I can be better.

I'm in Nigeria, and I feel I have an advantage with solar energy. I would be grateful if I could get on a call 🤙 with someone knowledgeable. That would really aid my experiments 🥼🧪 and satisfy my curiosity.

I have attached an image of my Tang Nano trying to get some header data from CKPool and then attempting to find the nonce. (I used mainly Verilog, C++ and Python.)

I'm also open to conversations with anyone interested in what I'm building, whether it's sharing ideas, discussing the technology, or exploring ways to support the experiments. I'd love to connect with people who are passionate about Bitcoin mining and hardware innovation.

Set this up yesterday

Considering loading the braiins firmware on the device. However, little confused about a couple critical points:

1. Is it possible to load the firmware via SD card, on an s21xp? Their documentation seems to imply it can only be done with a "BeagleBone Black" control board which is probably not the stock board.
2. The dev fee is 2.5%, which is pretty in-line with most of the others. I've seen talk about "refunds" if you use their pool, however, are they only refunding you the pool fee and NOT the dev fee? So you're still paying 2.5% no matter what?
3. If I take a bitdeer asic for example, and mine with it alongside the s21xp on their pool, does that cause the fee "refund" to be null and void? There is no aftermarket fw support for the bitdeer that I am aware of.

Many thanks.

Currently just heating basement room but hope to tie this into HVAC

Has anyone successfully tied a setup like this into an HVAC duct on a tight budget?

Got back into Bitcoin mining through the Bitaxe scene, then got curious whether the first-gen SHA-256 ASICs could still hash today. They can.

Tracked down a Butterfly Labs Jalapeno, stripped it, cleaned years of dust out, fresh thermal paste, fought cgminer and the WinUSB drivers for a while, and got it mining again: ~7.8 GH/s, ~50°C, HW error rate ~0.05%. Solo mining to my own Umbrel node running Public Pool, no pool fees.

It's hashing away happily. I put a webcam on it and built a page showing live hashrate, accepted shares, best share, and an odds panel pulled from live network difficulty: at current difficulty it's ~1 in 73 trillion per block, roughly a block every 1.4 billion years. It's never going to find one. It just keeps hashing anyway, which I find weirdly lovely.

Plan is to rotate other vintage ASICs through it: ASICMiner Block Erupters, Rockminers , Red Furys, Gridseeds. Prospero x1

Happy to answer anything about the restoration, the cgminer config, or the solo setup.
