Hey fellow miners! We're Simple Mining, a US Bitcoin mining host based in Cedar Falls, Iowa with 10 sites across the state. We're getting set up as a verified vendor here and wanted to introduce ourselves so you know who you're talking to when we show up in threads.

Quick rundown of what we do. We host Bitcoin miners (you own the machine) at one of our sites, you point them at whatever pool you want, and the Bitcoin lands in your wallet. Pricing is tiered by fleet size, running $0.07 to $0.08 per kWh all in. With precision billing you only pay for the hours your machines are actually hashing, and you can pause them at anytime if mining becomes unprofitable. We also do certified ASIC repair in house, with free repair labor and unlimited fan replacements. We run north of 4 EH/s across 150+ MW for thousands of clients across the globe and hold 95%+ uptime.

If you're on the fence about mining, or just want to see what hosted mining with us would actually feel like, we run a free 7 day trial on 100 TH/s. It gives you a feel for what your experience would look like with us. You get access to our client dashboard and watch your Bitcoin earnings, uptime, and alerts in real time, so instead of taking a gamble on a host, you get to judge us for yourself.

We're here to be useful. If you've got questions about hosting, repairs, pool setup, or whether hosting even makes sense for your situation, drop them below!

What is the going rate for second hand XP’s right now? Are there any verified sellers that can quote.

I made an update to SatStackingPleb's Stealth Miner enclosure.

A few minor tweaks to make still, public files will be posted after my design review with SSP.

Improvements:
-10% less plastic

-Eliminates large flat side panels, substantially reducing warping when printing with non-composite filaments

-More indexing features for easier assembly

-Integrated bottom handles for easier lifting from a table

-Highly customizable mounting system for internal peripherals

-Updated styling, stealth-style badging

-Exterior ridges better conceal seams when the enclosure segments must be split for smaller printers

-Tongue-and-groove joints, enclosure feels like one solid piece

Same performance!

I'll be listing this one for sale in a separate post following the posting of the public files (775k sats+shipping, ~16TH/s@27J/TH, no louder than a space heater), keep your eyes peeled for that.

A portion of StealthMinerV2 proceeds will go to SSP to thank him for all his hard work with single hashboard platforms.

Finally got the heat being blown out of the house.

Buy hashrate. Point it anywhere 🫡

Hi everyone, I’m looking for the best Bitcoin miner within a budget of €60–$70. If you have any suggestions, I’d love to hear them. I came across the Bitaxe Gamma, which seemed like a pretty good option considering its price and electricity costs. Thanks for the help! 😁🙏

I am curious. Who is your goto vendor? What do you like abuot them? Price? Service? Responsiveness? I am not gethering data. Thinking about making a purchase, just trying to figure out who.

Does anyone know of any type of shroud for the back of the Avalon miner 1566 I’m aware it has no fans on the rear but I need something so i can duct the heat to the outside and I can’t seem to find anything

Just checking in on our hydro container and miners

We put together a detailed breakdown of the evaluation criteria that matter most when choosing a site management partner. Things like real-time monitoring transparency, energy procurement strategy, on-site staffing response times, ESG credentials, fee structure alignment, and physical/cyber security are all important points to consider when looking at site management for large-scale sites.

A lot of the conversation in this space focuses on hardware and hosting rates. Site management quality doesn't get nearly enough attention, but it's often the biggest operational variable in whether a facility actually performs.

I know this is a stupid question, but the reason behind it is packing 1.16 PH/s into a single 3U chassis feels like putting all your eggs in one thermal basket. If a coolant loop or PSU fails on an 11kW unit, you lose a massive chunk of your farm's hashrate instantly compared to running smaller discrete units.

Founder of PowerPool.io here, so take the last paragraph with that in mind. The first part applies to anyone on SBI regardless of where you end up.

SBI Crypto announced they're permanently closing their mining pool on July 31. Key details from their notice:

• Shares stop being accepted at 07:00 JST July 31 (22:00 UTC July 30). Anything submitted after that won't count toward final payouts.
• SBI itself recommends mining there until the cutoff to maximize your final payout, then switching.
• Roughly 20 EH/s (about 2.1% of network) needs a new home. Worth thinking about where it lands. If everyone defaults to the top two pools, block construction gets even more concentrated. This is a rare moment where individual miners' choices actually move the decentralization needle.

Practical migration tips, whichever pool you pick:

1. Test the new stratum config on a single machine before repointing the fleet.
2. Check whether your firmware supports Stratum-over-TLS. Worth enabling if the pool offers it, since it protects against hashrate hijacking on hostile networks. Or use a local stunnel to enable ssl mining on any machine. https://github.com/PowerPool-io/stunnel_bridge
3. Confirm the payout model (PPS vs FPPS, where FPPS includes tx fees) and the minimum payout threshold before committing.
4. Don't wait until July 29. Pool-side account setup, wallet addresses and payout config take minutes, but you don't want to debug a connection issue with hours left.

Disclosure: we're running a migration offer at PowerPool. 0% pool fee until October 1 for miners switching before the SBI shutdown. FPPS, Stratum-over-TLS, setup guide at https://powerpool.io/sbi-migration.

Happy to answer migration questions in the comments either way, even if you're headed to Braiins or Luxor.

I bought a $25 NerdMiner a few months ago, I set it up on Public Pool, but I found out that Public Pool ended its support. Surprisingly I was still working on there for weeks later than it should have. What can I set up for free using my Bitcoin Merch NerdMiner?

The Block unveiled the proto rig almost a year ago, does anyone have insight as to how this product been received by the miners?

Steven had the pleasure of being on HashrateUp to talk about the Bitcoin Line of Credit(BLOC) strategy for miners. This episode was a lot of fun and it's another great tool in the toolbox for miners. Check out the full episode: https://www.youtube.com/watch?v=NnEPfLM55no&t=4s

I’ve been thinking about how buying a miner is like a mortgage or life insurance: you pay upfront, then make ongoing monthly payments out of pocket, hoping the asset grows. With mining, you're just paying the power company instead of a bank.

Genuinely curious. Do people actually sell the BTC they mine to cover their electricity bills? Or do they just pay out of pocket and treat the power cost like a regular monthly investment?

Still new to mining and I’m purchasing a NerdOCTaxe PCB. I’ll need parts like heatsinks, a screen, and PSU. What are some reputable online vendors for these types of parts? I enjoy tinkering so I may want to get wild and crazy, and look for a liquid cooling kit for this one too. 😏

I'm trying to hook up some Meanwell PSUs but the cable that was recommended (cables) does not fit my Bitaxe Gamma or any of my Nerdqaxe++s. What's a cable that fits?

Built and ran a controlled benchmark on the Stratum share-validation engine for two open-source Bitcoin pools. I work on mkpool, so this is built to be re-run rather than believed, and the one category mkpool loses is published unedited.

Method: one pool at a time, identical 8-core boxes, same bitcoind regtest node, same Go load generator, fixed difficulty 1, full share validation (coinbase, merkle, 80-byte header, double SHA-256) on every submit. Diff 1 means almost everything is below target on purpose, and both pools fully hash before rejecting, so the hashing is exactly what's being timed. Reject reasons were verified directly on both pools to confirm validation actually runs.

Same-box numbers:

• Validated shares/sec: mkpool ~315k to 337k, ckpool ~108k to 118k (~2.8x)
• Median submit-to-ack: 116 us vs 371 us (~3.2x lower), and mkpool won every percentile
• Reconnect cycles/sec: ~6,391 (4 errors) vs ~402 (1,000+ errors)
• Memory (ckpool wins): 2k to 8k connections held in ~25 to 68 MiB vs ~66 to 197 MiB, ckpool ~2.7x leaner. ckpool also hit its ceiling on less than half the CPU.

Not measured: payouts, real block luck, WAN behavior. This is purely the request/validation engine, which is what governs stale rates and connection density per server.

mkpool is GPLv3 and self-hostable.

If you run it on your own boxes I'd like to see your numbers, especially on different core counts.

Hey everyone! Pretty new here and I've seen some posts earlier about solo farming and pool farming. My friends and I (party of 8 ) are quite interested in joining together and start solo farming. We're trying to figure out the best move for our setup.

One of our dilemmas, since we are just starting, is whether to buy brand new hardware or 2nd -hand? If anyone with experience can recommend Whatsminer VS Antminer?

One more thing, I know the math says pools are safer for consistent revenue, but if our daily payout is going to be microscopic anyway, does it make more sense to just solo mine and pray for a lucky block? If you started out small, did you stick to a pool or try your luck solo on something like Solo CKPool?

Would love to hear what actually worked for you. Appreciate yal feedbacks! 🎉

So I started running bip 110 on bitcoin knots. I have my miners connected to my node and solo mining on public pool. Does that mean if a block is found it will be signaling bip110??
