r/BitcoinMining

I have around 300 s19s/21 boards USA

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?

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. 😏

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! 🎉

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.

Reproducible kit (load gen, orchestrator, sampler, both configs, per-box setup): https://github.com/Mecanik/mkpool-vs-ckpool-benchmark

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.

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?

Not financial advice, obviously, but the way I see it, mining profit all comes down to rig and setup costs + kWh. So, basically, Mined BTC value - Rig/Setup - hosting costs (kWh). And the math between home mining and hosted diverges across pretty much the entire equation, and there's a big difference between hosts.

Home mining has a cheaper rig startup (at least, it should or it's not even in the running), but residential rates are commonly $0.15+, which makes it unprofitable immediately. At some point, you're even cutting into your rig cost and actually spending money to mine.

Compass is big, you buy your rig, and the kWh works out around $0.08 for the S21 XP lisintg. About breakeven WITHOUT the rig. So, you will pay to mine for a while, but may break even eventually, a few cents at a time.

SimpleMining is tiered, which is nice, unless you are starting small. If you start with one rig, you are at that $0.08, plus the cost of buying your rig from them. The kWh goes down to $0.07 with larger setups, but that requires a larger upfront expenditure, so you'll be profiting more with a larger upfront spend, but it will take a while to break even.

Epic Mining has the same type of setup. You buy your rig from them, but they come in as low as $0.06 per kWh, making earnings higher, but you still have to worry about breakeven with the cost of their equipment. Logically, it should come quicker with the lower kWh, but it's going to take some time.

I feel like the biggest differences between these companies (aside from rig cost and kWh) is what rig you actually end up owning and its cost/value, and that Epic Mining is the only one that says they use fully green energy (Compass doesn't say and SimpleMining is mixed with gas and coal), if that matters to you.

So, with my understanding, am I right in thinking that hosted mining is the only possibility of breaking even when compared to home mining? Is the lower rate of Epic Mining the most likely way to break even, or are you better off with a lower-priced rig and $0.08 kWh?

If I were to lazy-rank this right now, I would say it's:

1. Epic Mining - lowest kWh makes for fastest breakeven, plus I own my rig

2. SimpleMining - slower breakeven, but I still own my rig

3. Compass Mining - similar to SimpleMining, but depends more on your setup

4. Home Mining - literally just for the sake of control or the experience, because it's gonna be tough to break even with normal residential power rates, but you still own BTC and your rig

Of course, any of these things are still investments and you could see them skyrocket if hashprice rips.

Is this a reasonable understanding, or do none of these actually have the chance of breaking even? Is it all just buying to hold and hope for a Bitcoin bull run?

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??

If there isn't any then for solo mining

Hello, i bought some M21 and S19, but they've had problems. I use a 190V to 227V transformer because the voltage here is low, but I've been having problems for a while. What setup do you use to get the "good" power from the utility company?

No, I can't call them to measure it, and I also don't know if it could be harmonics or surges. My electrical panel has a surge protection device (SPD) and an residual current device (RCD).

I was reading about toroidal transformer but i don't have money now to buy one (i'm from brazil, its like R$15.000,00 =~ US3.000,00)

Its used miners, but i have a lot of problems that the seller say it's working well, but when i test it, it has failures and i return then to the seller. failures like board didn't recognized, boards failing, and restarting miners.

energy stays at 226v

i already have return 7 machines (5x m21, 2x s19), only one m21 keep working good.
