Rough AI estimate of 650W 40TH mode puts it at $2.00 or \~ 2500 sats per day currently. Run it 200 days a year and you’ve got 500,000 sats. Maybe .01 BTC over 2 years. That ain’t bad!

RubDecent2168

The spec says: 30 TH/s @ 450W 40 TH/s @ 650W 50 TH/s @ 850W For all practical purposes all of that power will be turned into heat. So basically 100% efficient at converting electricity into heat.

Prestigious_Hair_656

It'll warm the room, just don't expect the heat to be free. You're basically paying your electric bill twice, once to the utility and once in wear on the machine. Pool payouts are tiny chunks every day or so, not waiting for a whole coin. You just need the miner, a power supply that can handle it, and an ethernet cable. If the efficiency is the same at 18W/TH, the 800W unit will be quieter and easier to run on a normal outlet without tripping a breaker. The bigger one just burns more power to spit out more heat, which only makes sense if you actually need to warm a garage.

startingtogocrazybro

The convenience is obvious, but locking liquid yield into non-liquid hashrate shifts all the market risk onto you. Once those rewards convert to TH, that capital is tied to the miner's efficiency, difficulty adjustments, and operational fees. I assume this is good for aggressive accumulators who already planned to reinvest every cent into power.

palmdata

miners are still doing the boring math: ~$36.5/PH/day means a 200 TH box is about $7.30 gross/day before power, pool fee, and rejects. wall watts plus a 24h accepted-share report beat the BTC headline.

palmdata

~929 EH/s and hashprice around $37/PH. a 200TH box is only ~$7.50 gross/day before power. next retarget looking soft +~3% from here, so budget the low case not the btc headline.

rwilley71

Start with a Bitaxe Gamma. It runs under $100 to purchase and mines around 1.2 -1.5 TH. You won’t pool mine anything but tiny sats that takes years to accumulate anything significant but works well as a solo miner. Just think of it as a lottery ticket that renews every 10 minutes.

933 EH/s and ~127.45T difficulty is the part most home miners miss: the box can be healthy and still earn less next retarget. At ~$37/PH/day, a 200 TH machine is only roughly $7.40 gross/day before power, pool fee, downtime and rejects. I’d budget from the low case, not the headline BTC price.

palmdata

hashprice around $38/PH/day puts a 216 TH box at only ~$8.20 gross/day. a 3.7 kW box burns ~89 kWh/day, so 6¢ power is ~$5.30 before pool fee, cooling and downtime. the wall meter and a 24h hash report tell you more than the BTC price headline.

14 TH/s for $12.99 on a mobile app should've been a red flag from space

HSuke

I'm not sure what there is to be impressed by. The lessons are super short and basic. There are plenty of free crypto lessons online already that go over topics in more detail. It's just a gateway to advertise for their virtual BTC mining product. You pay $21.99/TH for a 1 TH entry level miner. And the way your purchase these is by buying one of their NFTs that represents a purchase contract. I'm certainly not touching this. https://academy.gomining.com/articles/gomining-vs-cloud-mining

**Update: My NerdOCTAXe Hydro arrived today my first-day results, power, temps and a cooling scare** Quick follow-up to my earlier post. My **NerdOCTAXe Hydro** arrived today and I’ve spent most of the day setting it up and testing it. Overall, I’m pretty impressed so far. The unit arrived well packed with a **Mean Well LRS-350-12 PSU**, dual radiators and the hydro setup already assembled. The seller had handwritten a recommended setting of **850 MHz / 1200 mV**, but I decided not to jump straight to that and tested it incrementally. I did have one scare early on. At 800 MHz the ASIC temperature suddenly climbed to around **90°C** and the miner shut the ASIC power down as it should. At that point one radiator was warm and the other was cold. Both pumps were powered and vibrating, so I shut everything down, checked all the connections, moved/tilted the unit gently and restarted at the default 700 MHz. After that, both cooling loops started behaving identically. Both radiators are now within about a degree of each other and all four coolant tubes are around **33–34°C**. Since then the cooling has been rock solid. **One-hour test results:** **700 MHz** \~11.35 TH/s \~52°C ASIC **248 W at the wall** 0.08% rejects **750 MHz** \~12.17 TH/s \~53.5°C ASIC **271 W at the wall** 0.00% rejects **800 MHz** \~13.04 TH/s \~56.2°C ASIC **294 W at the wall** 0.00% rejects The power figures are measured at the wall with a **WiZ smart plug**, not the miner’s internal power estimate. At 800 MHz the miner itself was reporting around **16.6 J/TH internally**, while measured wall efficiency works out closer to **22.5–22.6 J/TH**. Noise is also better than I expected. I measured approximately **51 dB from about a meter directly in front of it**. I also discovered that my original pool connection was causing a surprisingly high rejected-share rate. I started on Public Pool and was seeing several percent rejected. I switched to a Frankfurt-based Stratum server at [stratum.bitaxe.de:3333](http://stratum.bitaxe.de:3333/), and rejects basically disappeared **0 rejects out of more than 1,200 shares** during the 750 MHz test and again 0 during the 800 MHz test. Latency has been around **40–50 ms from Sweden**. For now I’m leaving it at: **800 MHz / 1210 mV / \~13 TH/s / \~294 W at the wall** and letting it run overnight before even thinking about the seller’s 850 MHz recommendation. So after day one: a bit of excitement with the cooling loop, but once that cleared, the machine has been surprisingly stable, cool and quiet. I’ll update again after the overnight run if anyone is interested.

palmdata

for passive accumulation, the two numbers that matter are all-in ¢/kWh and the miner's J/TH. if a platform won't show the miner-side hash, payout formula, and every fee, walk. difficulty does the rest over time.

palmdata

fun if you treat it like a heat/noise hobby and run the numbers first. at ~$31–32/PH/day, a 30 J/T box burns 0.72 kWh per TH/day; at 8¢/kWh power alone is ~$0.058/TH/day, so it’s negative before pool fee and downtime. cheap or curtailed power changes the math.

palmdata

1) hashprice, then network hashrate and difficulty. Hashrate tells me when the fleet is coming online; difficulty tells me how fast the same box is getting squeezed. I also watch rejected shares and uptime because paper TH is useless if the site is fighting it.

abaird04

To account for any imbalance in the coins, use two coins. Only record the flips that result in either HT or TH. You decide which you want to count as 1 and which you want to count as 0. For any flips that are TT or HH, throw them out. That is the debiasing method.

ExtensionHat5598

Odds are crazy low but you only need to get lucky once. Friend of a friend in my mining group hit one with a single Bitaxe after like 4 months running it. He was at 1.2 TH/s I think. For 13.8 TH you got a little better shot but still its basically lottery

Choice_Camel_3166

Thanks, that’s exactly the kind of real-world information I was looking for. Good to hear it’s actually holding 13.5–13.9 TH/s at around 235 W. I’ll keep the air-bubble issue in mind when mine arrives. How long have you been running it altogether, and what temperatures are you normally seeing?

perplexed_dawning_li

The pump on mine started making a clicking noise after about two weeks. Turned out it was just a tiny air bubble stuck in the loop, tilting the unit 45 degrees while it was running sorted it out. Getting a steady 13.5-13.9 TH/s at the wall, power hovers right around 235W so the advertised numbers are pretty close. Solo mining on one of these is a lottery ticket but someone has to hit the block eventually.

EveningStock9152

Actually, there are some pretty insane real-world examples. People have found Bitcoin blocks with solo mining setups that were **way below 20 TH/s**. A Bitaxe running at roughly **0.5 TH/s** found a block in July 2024. There have also been solo block finds around **1 TH/s, 1.2 TH/s, 6 TH/s, 10 TH/s and \~17 TH/s**. The \~10 TH/s case is especially crazy — at the time, the Bitcoin network was running at hundreds of EH/s, so the miner represented an almost microscopic fraction of the total hashrate. That’s what makes solo mining with these little machines interesting. You’re not realistically “competing” with the big miners — you’re basically buying an absurdly cheap lottery ticket that happens to make you a valid block candidate. And every once in a very long while, one of these tiny miners actually hits it. So yeah, the odds are ridiculous, but there are real examples of **sub-20 TH/s miners finding full Bitcoin blocks**, including setups below **1 TH/s**.

labatte

You can get a 1TH/s miner for pretty cheap, and run it as a solo miner (not part of a pool) in the hopes of hitting the lottery. Yeah, you’ll probably never find a block, but a simple lottery miner running 24/7 will cost you about $0.06/day in electricity. It’s cheaper than buying a $2 powerball ticket, which you also will never win, but at least you can see your Bitcoin miner as contributing to the strength of the network you are invested in.

riscten

There are sites out there putting numbers on what you're trying to do. Like [https://www.asicminervalue.com/](https://www.asicminervalue.com/) and [https://hashrateindex.com/rigs](https://hashrateindex.com/rigs) Ultimately what matters for you will be acquisition cost and TH/s. Since power is free, you can ignore power consumption. Find the cheapest miner you can have delivered to you with the highest hashrate. Then figure out how much work, space and attached hardware you'll need to pay for to make it all work. At $40K investment you're basically starting a business, so get those spreadsheets out or get a Claude Pro subscription and get those prompting skills to use. There's also a billion Youtube videos covering this. A lot have outdated numbers, but you'll get a good idea of the maintenance work involved and the noise levels. Hodlers are all for independent miners, especially solo miners. We need more of you guys to maintain decentralization, so you got all our support.

450 btc a day get mined right now, and after the next two halvings that is closer to 110 a day. from the shop side the interesting number is that a single S21 at 200 TH against 900 EH/s earns about 0.0004 btc a day, so a whole coin takes years of uptime. supply gets tighter faster than most people plan around.

palmdata

the honest comparison is cost per coin, not cost per machine. take your kWh rate times the J/TH and you get a mining cost per btc, then compare that to spot. under about 6 cents a kWh most modern boxes still beat buying, above 15 cents they do not, and that is before the 10 to 15 percent you lose to downtime and derate in a hot month.

palmdata

one 3.2 kW machine is 27 amps at 240v, so it is a dedicated 40 amp circuit and about 11,000 btu of heat per hour in the room. that is the real wall at home, not the price. at 12 cents a kWh a 20 J/TH box needs roughly 60 dollars a day per PH to break even, so the price move helps but it does not fix a residential panel.

Folding at home. Then I was curious, since this was a resource (compute), could I passively earn? Found BTC in 2012. Relapsed in 2014. Woulda coulda millionaire billionaire story. Been clean for about 2 years. Got a new car out of it tho. Last time I sold BTC (6 over 6 months... About 8-9 years ago), I was houseless, living in my $500 ride. McDonald's bathroom hot water towel showers. Sleeping a few blocks from my tech job ($16/hr managing a production art lab). I didn't realize that was a $60k job the way my output was. Car got stolen. Went to Louisiana and was a plug for a while. Got kicked out of the trap, back to West Coast. By then my previous gig and career prior that were but a distant memory. Continued hustling- enrolled in college. Spent all my grants, tuition and scholarship money on mining equipment and buying BTC. My apartment was just mining gear in the second bedroom, a mattress no box in the main, a computer in the living room, and a table and chair for it. 95°F in snowy winter with the heat off. Sold equipment when my 42 TH/s was no longer profitable. A year later my auction house $250 special got stolen from my parking lot. Sold nearly all my crypto for ~$38k. Original investment (equipment, electricity, buying crypto) roughly ~$9-11k. About a %245 return. Not bad. Bought a new car for uhhh $29k down. Was wild taking the Greyhound 200 miles away because this happened during COVID, and due to the chip shortage, there were zero cars in the make model trim color package I wanted. Rep that held the car for me picked me up from the bus station in the whip. 33 miles on the odo. Told him to pick up his greasy fries out of my cup holder. Broke the dealerships money counter with the small bill bonanza Bodega haul. That left me with enough BTC to take a vacation for a few weeks to just lay on a beach and not really dent it, because I sold at a point right before it corrected and just re bought. But... Relapsed again. This time due to university pressure. I had stopped hustling on the street and was hustling scholarships, just investing in stocks, BTC, and oh wait I didn't actually stop hustling... Just feeding my addiction with petty exchanges. Relapsed hard into what would be a 6 week supply, in the face every 3-4 days. String of love letters. Then vendor disappeared. Then a market. Left with nothing but some fucking memories? Kind of... None of those friends during the fast times and $5 bags stuck around. I knew that's how it went, wasn't my first rodeo, but I was a different person now- in uni, new ride, purpose on my shoulders. Fed into the relapse. Took a year off during my undergrad. Got a job. Two years later was two years ago. Decided I have what I needed in life finally. Put everything I had down on a nice two story in the safest part of town, 12 minutes from work. New car. Two beautiful dogs. The best health insurance. Got my weight and health under control. How much BTC am I holding? $500 worth. How far would I be without crypto? I mean hell I might have made it to here, but crypto was my safety net during at least half a dozen critically devastating points in life. It facilitated the absolute worst and abhorrent vices. When I was done hanging myself and didn't somehow die, it gave me that same rope and I was able to climb into whatever crumbs are left of the American dream. Did I answer the question? I forgot what we were talking about.

The mechanics are working against you here, and it's worth knowing why before you go looking for someone. Almost nobody mines a block alone. Small miners point their machines at a pool, and the pool pays them out of its own wallet, so those coins were never fresh coinbase anyway, they're just ordinary transfers. And the amounts are nothing. I run a small miner at home, 4.63 TH/s, and it earns about 237 sats a day. There is no local guy sitting on a pile of coins he mined himself. The ones actually collecting block rewards are companies with accountants and compliance people, and they are not meeting anyone in a parking lot. Which means whoever answers an ad like yours is, almost by definition, not a miner.

BTCGlobeLive

Nothing has to give, and that's the genuinely surprising part. A chip is a 100% efficient heater, exactly like the element it replaces. Every watt that goes into an ASIC comes back out as heat - computation doesn't consume energy in the thermodynamic sense, it just borrows it on the way through. So a kWh through a miner heats your tank the same as a kWh through a resistive coil, and the bitcoin is genuinely free on top. That part of the pitch is real physics. The catch isn't energy, it's the two things below. **What the heat is worth.** I run a small miner here, so these are measured rather than estimated: 4.64 TH/s at 86.75 W, read off the machine tonight. Against the network as it stands right now (block 962,175, difficulty 127.5 trillion, about 888 EH/s) that's 235 sats a day for 2.08 kWh. Which means **each kWh routed through it produces about 7.2 cents of bitcoin** at today's price. Someone above measured 8 kWh a day for their tank - at that rate, roughly 58 cents a day, or $210 a year, against a unit that costs maybe $1,400 more than an ordinary heater. Six or seven years, and that's assuming difficulty stands still, which it never does. **The comparison that actually decides it** is the heat pump point made further up, and it's the strongest objection in this thread. A resistive heater is ~100% efficient; a heat pump is ~300-400%, so it does the same job on a quarter of the electricity. Set the two against each other: * mining heater: earns ~$0.072 per kWh it burns * heat pump: saves you 3 of every 4 kWh, worth 0.75 x your electricity price They break even at about **9.6 cents/kWh**. Below that, the mining heater is ahead. Above it, the heat pump wins and no amount of bitcoin closes the gap. With a current-generation ASIC (13 J/TH rather than my 18.7) that crossover moves up to roughly 14 cents. So the honest version: it's not a scam and nothing violates physics, it's just that the competition isn't a dumb resistive tank, it's a heat pump - and which one wins is decided entirely by your local power price. Anyone can redo that arithmetic with their own rate in about a minute.

Azelphur

Bitcoin miners used as heating has been around for ages, this concept is not new, at all. People were doing it back in the early 2010's. The first law of thermodynamics is the law of conservation of energy, that is, you cannot create or destroy energy, merely change its state. When you put electrical energy into a Bitcoin miner, that energy has to go somewhere, you cannot consume it. The answer to where it goes is heat, all of it. "Yea Azelphur but what about the fans that's kinetic", shut up fans goes to friction goes to heat. Everything goes to heat. In terms of performance, it really depends how much energy the water heater leaks. But, I don't imagine that running water past a heater element or over a hot chip is significantly different, so I'd guess about the same. So the questions to ask are: - How much more than a comparable unit does this heater cost? Their website says it's 3.3kw. Gemini tells me that a 3.3kw electric water heater costs between $150 and $400. We'll pick the $275 midpoint? So it's $2,000 - $275 = $1,725 more expensive - How much money will I earn from the mining? This is tricky, because it depends how long it needs to run, which is dependent on how much hot water you use. Their website reckons $326.32/yr, given the current mining scenario and their 140TH/sec, that's around 15 days of mining, at 3.3kw that's around 1,200kWh/yr, which is a reasonable enough number I think. I'm think the $326.32/yr number maths out. - $1,725 difference divided by $326.32/yr profit works out at around a 5 year break even time, although this doesn't account for difficulty changes. Real world? After doing the math? My tl;dr would be: - If you must install an electric heater, sure, it's a reasonable value proposition. It'll probably take more than 5 years to return a profit, but I'd think it'd return a profit eventually - Heat pump will probably save you more money if you can get one.

Hersh-_-

Because that method only works if it's a perfect 50% chance for H or T. Unfortunately we live in reality and our coins/flips are not perfectly equal probabilities so you need to correct for the bias. Let the probability of a heads be P. H=P H+T=1 T=1-P P does not necessarily equal 1-P however, if you flip a coin twice: HH=P^2 TT=(1-P)^2 HT=P(1-P) TH=(1-P)P Therefore the probability of HT and TH is the same no matter the probability of H or T That is why you ignore any HH or TT, and associate each HT or HT with a 1 or 0 to generate your random string

Hersh-_-

Flip a coin twice and calculate bits according to the von Neumann method where HH and TT are ignored and HT=1 and TH=0

lifeanon269

Hopefully you didn't input your dice rolls directly into the online website and instead you used an offline amnesiac system and copied over the tool for offline use from his below repository, correct? https://github.com/iancoleman/bip39 Or by using ColdCard's python script here: https://coldcard.com/docs/rolls.py Also, both these tools are compatible with any hardware wallet that can import a seed phrase since after inputting your dice rolls as entropy into the tool, it will provide you with the valid seed phrase for import. Since you need to type and input every dice roll into the tool itself, might as well use both tools at that point since if you took the effort to set up an offline computer to run an offline website or python script, simply copying and pasting the dice rolls into both isn't much more effort at that point and removes the need to trust either one individually. Or, if you aren't technical and wanted to avoid needing to use an offline amnesiac computer to validate/generate a seed phrase with third-party tools, there are a myriad of ways to create a seed phrase from dice or coin flips that map directly to the BIP-39 word list. Then most HWW will be able to calculate the checksum for the 24th word. To avoid bias with coin flips, you can flip a coin twice and if it is HH or TT, discard the result. If it is HT, write down a 1, if it is TH, write down a 0. This removes bias from the coin to give you an even 50/50 chance. Bias in dice is inherently trickier to remove, so for anyone going the dice route, I highly recommend at the very least using casino dice.

junkhead_7

The sheer amount of miners doesn't matter. What matters is the TH/s. If mining becomes unprofitable, a lot of miners will leave. Some malicious actors can join mining with a lot of mining power and state-of-the-art machinery in order to coordinate a 50+1 attack while shorting Bitcoin - because rest assured it'll tank like crazy in case there will ever be a double spend.

magma_lakes

Flip a coin and use the von Neumann method to generate random bits where 0 and 1 have a 50/50 chance of appearing, even if your coin is biased: HT -> 0 bit TH -> 1 bit HH -> reject TT -> reject The reason this is unbiased even if the coin is biased is simple. If P(H) = p, then it must be that and P(T) = 1 - p. So, the probability of getting HT is P(HT) = p(1 - p), and the probability of getting TH is P(TH) = (1 - p)p, which are both clearly the same, P(HT) = P(TH) = p - p\^2. Given that 2 coin flips are needed for a single bit, and that half of all flips end up getting rejected - on average - the expected total number of coin flips is 1024. The von Neumann method can also be applied to dice.

DiamondHandsDarrell

A bit serious and a bit tongue in cheek, but how many Tera hashes is that? A $72 miner, The Bitaxe Gamma delivers 1.2 TH/s of real ASIC hashpower at just 18W. I don't need to get all of them, just one wallet would work. Again, I don't understand it enough, but why not leave it on a Secure computer in a secure wallet that's backed up or on a major exchange such as Coinbase?

magma_lakes

Generate your wallet by tossing a coin using the von Neumann extractor method, in order to cancel out any bias the coin may have. Toss the coin twice, if you get: HT -> 0 bit TH -> 1 bit HH -> reject TT -> reject Repeat that 256 times. This guarantees that - even if the coin is biased - you are still mathematically guaranteed to have a 50/50 chance of obtaining a 0 or 1 bit. You can then use that private key to generate a public key and address on an offline Linux PC, or an entire Bitcoin wallet, if you so desire.

Tokentactico

Anyone in the mining side of this can tell you the real green flag isn't the flag emoji, it's the halving math nobody wants to model out. I run a small setup (~80 TH, mixed efficiency around 14 W/TH) and even now, with electricity around $0.047/kWh, my margin per TH is thin but positive, maybe a few cents a day after maintenance fees. The problem is April 2028: subsidy gets cut in half again, difficulty almost certainly keeps climbing regardless, and unless BTC price appreciates enough to offset that, the same rig goes from marginally profitable to actively costing more in maintenance than it produces. Nobody posting "number go up" charts is pricing that in. If you're evaluating BTC as a long term hold versus a productive asset, mining hardware specifically has an expiration date built into the protocol that equities don't.

You bought a currency that provided equivalent amount of TH/s of mining power, and got rewarded accordingly on their Wallet

Halving math on this cuts both ways for miners specifically, worth separating from the "just sell BTC" question since a lot of people in mining threads conflate the two. If you're mining, the thing that actually forces the sell decision isn't price, it's your all-in cost per TH versus reward per TH. Take a rough mid-efficiency rig at 12 W/TH, $0.05/kWh electricity: that's about $0.0144/TH/day just in power, before hosting or maintenance fees. Reward per TH scales with (BTC price × block subsidy) / network difficulty. Difficulty has kept climbing basically every quarter this cycle regardless of price, so your reward per TH has been shrinking even in months where BTC went up. The April 2028 halving cuts the subsidy in half again. Unless price has appreciated enough by then to offset both the halving and whatever difficulty does between now and then, a bunch of mid-and-lower-efficiency hashrate goes cash-flow negative on electricity alone, not just unprofitable on ROI. That's usually what actually triggers hashrate coming offline and difficulty dropping, not sentiment. For someone just holding coin with no mining exposure, none of that math applies to you directly, it only matters insofar as a wave of miner capitulation can spike volatility short term. So the "time to sell" question really has two separate answers depending on whether you're holding the asset or holding the machines producing it. Worth being explicit about which one you are before taking advice from either camp.

Your numbers are off. My axe miner is 500 gigahash and this says chance is about 1 in 10 million per day. For 1 TH it should be about 1 in 5 million, not 1 in 5 billion like you wrote. Definitely better than the lottery.

Edit: I just checked and the Bitmain Antminer S21 Hyd (335Th) can hash 355 TH/s and costs $4,200. Current BTC hashrate is 647.84 EH/s. [https://www.coinwarz.com/mining/bitcoin/hashrate-chart](https://www.coinwarz.com/mining/bitcoin/hashrate-chart) [https://koinly.io/blog/best-crypto-mining-hardware/](https://koinly.io/blog/best-crypto-mining-hardware/) 647.84 x 0.51 = 330 EH/s 330,000,000 / 355 = 929.577 929,577 units x $4,200 = $3.9 billion So it looks like a 51% attack could be achieved for under $10 billion by a motivated entity with sufficient resources.

Numerous_Ruin_4947

I realize that. ChatGPT does help to create a rough framework which can be tweaked. For example, the Antminer S19 XP Hydro can hash at 255 TH/s. 609 EX/s x 0.51 = 310.59 EX 310.59 x 1,000,000 = 310,590,000 TH/s 310,590,000 / 255 = 1,218,000 Antminer S19 XP Hydro costs around $5,000-$6,500. I'll use $6,000 1,218,000 units x $6,000 = $7.3 billion It would take around 1.2 million Antminer S19 XP Hydro ASIC appliances to hash 51% of the current BTC hash rate. What if an entity with enough resources starts to manufacture these ASIC appliances in secret? Perhaps their upfront cost would be $5-10 billion. And daily costs of around $8-16 million. These numbers may not exactly be accurate, but it would cost less than $20 billion potentially to perform a 51% attack. For how long can the attack be executed and what can be prevent it? A fork?

# Calculation Breakdown: # 1. Current Bitcoin Hash Rate: * As of recent data (which fluctuates), Bitcoin's total hash rate is around **440 EH/s**. * To control 51%, you need to acquire approximately **224 EH/s**. # 2. Hash Rate of Mining Equipment: * A common miner like the **Antminer S19 Pro** produces around **110 TH/s** (terahashes per second). * 1 EH/s = 1,000,000 TH/s, so you would need around **2 million Antminer S19 Pros** to achieve 224 EH/s. # 3. Electricity Costs: * The Antminer S19 Pro consumes about **3,250 watts (3.25 kW)**. * At 224 EH/s, the total power consumption would be about **6.5 GW** (gigawatts). * At a price of $0.05 per kWh, daily electricity costs alone would be: 6.5 GW×24 hours/day×1000 kWh/GW×0.05 $/kWh=≈7.8 million dollars per day6.5 \\, \\text{GW} \\times 24 \\, \\text{hours/day} \\times 1000 \\, \\text{kWh/GW} \\times 0.05 \\, \\text{\\$/kWh} = \\approx 7.8 \\, \\text{million dollars per day}6.5GW×24hours/day×1000kWh/GW×0.05$/kWh=≈7.8million dollars per day

New 110TH S19 Pro is about $3k So $16M worth of equipment.

>Every miner on the network has the same chance to find a block. That's just not true. The chance is determined by their machines hash rate. A modern machine crunching 300 TH/s versus a nerd miner V2's 70 KH/s has one billlion times greater chances to find a block; simply by doing a billion times more work, and being a billion times more efficient. What you're saying is like someone who buys one lottery ticket is is just as likely to win as someone who buys a million of them; you're just wrong.

onetruecharlesworth

https://start9.com/ Personal preference, I run extras just to help secure the network. I run a small 4TH antminer in my utility room for a small loss each month for the same reason. I’m heavily invested in BTC so I figure I should do my part in protecting that investment.

Buy the apollo 2 full node/low TH miner it’s perfect for ya

They are good for longer than 1-2 years. The less powerful machines are still profitable in bull markets. For example, taking the original numbers, with BTC at $60k, and cost of BTC at $35k with the best machines, you could still make something more than $0 using a machine of ~50% TH/s against the cutting edge.

drunkmax00va

The Antminer S21 operates at a speed of 200 TH/s. For your Nerdminer to perform the same amount of work that the S21 does in a single second, it would need to run continuously for about 100 years.

KneeGrowslaya

Actually i saw this yesterday and ran the maths. If it was 10 bitmain ks5 pros with 21 TH/s and the power consumption of 3400W each it is actually not that much off. The power consumed equals 17,36 MW/h and they could have potentially mined 45 000 kaspa at current difficulty. The 100k comes from a fact that this probably happened a month or two before the article was posted when yield was much much higher, they could have mined literally 100k kaspa. Not a 100k worth of kaspa but a LOT

tldr; Toronto-based Bitcoin mining company Bitfarms reported a $27 million net loss in Q2 2024, with a 16% decline in revenue to $42 million quarter-over-quarter, attributed to reduced block rewards from the BTC halving event. The loss per share was 7 cents, including a $1 million non-cash expense for revaluing warrant liabilities. The company produced 614 BTC at an average cost of $30,600 per BTC, with total cash cost per BTC rising to $47,300. Despite challenges, Bitfarms is pursuing expansion and efficiency improvements, aiming for 21 EH/s and 21w/TH by year-end. The firm is also facing a hostile takeover attempt from Riot Platforms. *This summary is auto generated by a bot and not meant to replace reading the original article. As always, DYOR.

It’s me. I’ll have you know I mine over 2TH/s an hour!

miros2424

No, they have diminishing returns with difficulty rising all the time. I did the calculations with present day difficulty. In 3 years they are worth less than 1/10 the cost. For example the 95TH/s miner was 5000$ over 3 years ago and required 5 of them to make 1 bitcoin in 1 year consuming 10,000$ of electricity. That is 35,000$/bitcoin.

NiagaraBTC

My 100TH miner was getting about 15000 sats per day before the Halving +it's off now for the summer so not sure currently, but it would be less). Cut in half it would be 7500. 7500*0.06= 450 The 6TH miner would definitely earn *less than* 450 sats ($0.30) per day.

KindlyBlacksmith4003

I see network hash rate at about 650 million TH/s. S21 Pro at 234 TH/s. So yes, the equivalent of about 2.8 million S21s.

GOMINING BEST BTC CLOUD MINING SERVICE AROUND!! GoMining NFT Crypto Cloud Mining I would recommend GoMining it uses NFT powered mining and is probably about one of the most legit cloud mining services I’ve used I currently get about about $10-$20 per day deposited into my BTC wallet the more you invest the more you make, you can upgrade your NFT by 2 ways you can upgrade your TH, which is the power your miner has,same way as like a real miner would have. You can also upgrade your W/TH, which is the amount of “power” your nft uses, the higher upgraded it is the less service fee you have to pay per day, which also increases your daily pay out. I’ve seen on the app some people that make upwards of $1,000, $5000 and even up to $15,000/day, yes it takes a lot of money to get to that point but it is possible, theres also discounts you can get from paying the maintenance fee in their crypto currency, its called GMT (GoMining Token) then there is also a “game” in which you click this button that says service daily and if you remeber to do this daily you’ll get 0.3% discount that is stackable as long as you tap the “service” everyday and that discount will go up to 3% maximum, then also as your level increases based on your total TH you will get a 0.6% discount whenever you get a total of 5TH, 10TH, 50TH, 100TH, 200TH, and so on till you reach level 20, there is also pool mining where you can combine your TH with other players with up to 50 players per pool and get rewarded if your pool mines the current block it’s randomly picked which pool wins and mines that current block but your pool has a better chance of mining the block the higher TH your mining pool has combined, but depending on weather you can get in a good pool that take the game serious and actually makes their pool a good and competitive to keep the total amount of TH up then you can make a lot pool mining but thats pretty general description of how it works and what to do to start out and give you the best shot at starting up, this is my referral link to anyone that would be open to trying this app it really does work and I’d recommend it to anyone GoMining https://gmt.io/?ref=8xL6i

One of the benefits of free incremental energy cost is that you definitely don't need to run S21s or similar. There's plenty of S19J's K's etc that list for hundreds of dollars. Even if you estimated an effective daily hashrate of 35 TH/s (25-33%), they'd be netting a million sats/year. That'd pretty much pay for a run of the mill last generation miner, plus they can claim depreciation on top of that. Honestly, if you had a 5 year payback, most companies would jump at the chance to increase revenue and margin for only capital investment with hardly any impact on COGS. Difficulty is set to make a gigantic jump next week, but that could be temporary without positive exchange rate variance.

LargeSnorlax

Electricity included in the rent ≠ you can run hundreds of dollars of extra electrical through your apartment People make this mistake all the time and buy expensive miners only for (big shock) their electrical to get cut off a month or two in because paying for routine electrical use doesn't mean they're going to fund your Bitcoin mining habit You're also not going to be able to run a s21 in an apartment without two things happening: - You going insane because of the noise - You getting noise complaints from neighbours above, below, and beside you https://youtu.be/e60ol6v5r_0?si=igvce1ksmbnvRsfN&t=161 An s21 sounds like a vacuum cleaner on at full volume, all day every day, if you'd be pissed hearing your neighbours operating a shopvac 24/7 then you'll understand what your neighbours are going to hear It's pointless to buy an Apollo II as well because you get 10 TH/s which is pointless, it's 1/20th the power of a s21 so you may as well just take the money it takes to buy one and buy Bitcoin with it If anything, use your graphics card and use nicehash to mine NEXA or something but mining is largely pointless these days even if you have "free" electricity

chuckrabbit

Sorry that can’t be right. Hash power has nothing to do with supply cap. Total network hash date deployed is already at ~6x10^20 H/s TH is 10^9, and network is about 600M TH/s.

tlztlz

Yes, as a funny doodad. An actual S19 Miner has around 140-200TH/s. This one has 80KH/s. So an S19 is 2\*10\^9 better. 2 billion times. 2 billion seconds equals around 60 years. This little bad boy needs to run 60 years nonstop what an S19 does in a second.

Corbimos

TH is TH. If you have 200TH of miners. It doesn't matter if its one unit, or 20 x 10TH units. They all produce the same amount of hashes. The power requirements are where you lose money, since 20 units would use more power than one unit. the difficulty affects the hash of all miners the same.

Corbimos

TH is TH. The profitability is all in energy efficiency. If you aren't paying for electricity, then it's the same to you. If you look at resale value, the 200 TH, more efficient model would probably sell for more. I'd go with that since you may not be able to mine for free forever.

4lt3r3dR341ity

Math equation is quite easy, Cost of equipment Hash power Electricity rate Current btc price For instance, currently 1Ph/s yields around $50-60 a day. One S19 miner is $500 for about 100 TH/s So $5,000 for 1 Ph/s Take you 10 months (at current price) to ROI on device cost, (you’d factor in your own expenses(elect rate)) Your biggest enemy isn’t the buy in cost, it’s electricity rate. Users who can do hydro electricity (at home let’s say) make a KILLING mining with ancient equipment. I’ve been able to sell a lot of “older” equipment to miners who do hydro electricity mining.

No, you will never find a block this way. A modern CPU can make a few million hashes a second. A decent GPU could do a billion. And an ASIC will do many trillion hashes a second. When someone solo mined a block with 17TH/s it made the news https://x.com/altair_tech/status/1667283976912863233 a miner like this could expect 1 block every 450 years.

With cutting-edge ASIC technology, it boasts a substantial 2 TH/s hash rate with an impressive energy consumption of 1800 W. Users can earn up to 2,000 BDAG daily, as X100 optimises your earning potential and optimises the mining process. You can also mine Bitcoin and Kaspa with BlockDag X100, as it is equipped with the SHA-256 algorithm. With advanced ethernet connectivity and enhanced heat dissipation, it is an ideal choice for pro miners.

So… an entity with >$17.5B, 10 GW of power generating capability, and the ability to somehow manipulate the supply chain to buy $17.5B worth of current gen mining equipment without raising suspicion (or to build a supply chain capable to manufacture at least 650,000,000 TH/s of mining without raising suspicion). That and it all has to go online within a very short timeframe, or else you’ll garner suspicion, and older miners being recommissioned to defend the network. I mean, yeah, it’s *possible*. Not probable though.

CockroachSeparate827

I just read the press releases for the mining groups and add it up. You have a site here at 650 MW and a site there at 900 MW and before long you're looking at real fuckin power. I would know more exactly but the bitcoin mining companies sued the federal government to keep their power use secret. The minimum credible figure for Texan mining alone is 2200 megawatts as of October 2023, but this does not include a survey of all the Texas sites nor a report on the expansions made since then. Since we know that Texas is less than 10% of global hashrate, we know global hashrate is wasting over 20 gigawatts. Another approach is as follows: Global hashrate: 659 exahash/sec This is 659 million terahash per second. One of the top mining units for efficiency is a WhatsMiner M56S++, a watercooled 5.55 KW unit with 230TH/sec. 659 million divided by 230 x 5.55 KW gives 15 terawatts, assuming the most efficient newest miner is doing all the mining. Yet another underestimate of power wasted.

DiedOnTitan

Number of Bitmain S19 units required = 585,840,000 TH/s (current hashrate) / 110 TH/s = 5,325,818 units 5.3 million S19 miners to support current hashrate of 585 EH/s. There are like 1,000 available on eBay for \~$1,000 a pop second hand. For new Bitmain S21 at 234 TH/s cost is $6,300 = 2.5 million units. = $15 billion dollars. before electric, wiring, housing and cooling. Even if supply were available (not close) you would only double the mining rate and cause the network to take 20 minutes per block for 2 weeks after pulling out. Satoshi's game theory makes this economically utterly impractical and just about theoretically impossible.

Less than 14 w, so approx. 122 kw hours, so at $0.07 like $8, or $12 at 0.10, etc. In terms of earnings, current rate is \~80 SATs/TH/day, so 0.5 TH is \~14600 SATs per year (\~$13.60). So, slight profit if electricity is low enough, but the SATs will probably be worth more in the future. You're not going to justify the cost of the unit itself in this equation, as even if electricity were free, it would take years to pay for itself. That's probably why a lot of people just solo mine, or if buying it anyway, maybe add some hashrate to other hashrate they are generating to get to payouts (ex. I have an S17Pro I'm mining with to Ocean... every 0.5 TH/s helps.). Keep in mind the BM1366 is the same ASIC chip from the S19XP, so this is a similar boat the big industrial miners are in, just at a different scale. The nice thing about solo mining (or mining with Ocean or certain other pools), is that you're adding hashrate to the non-centralized side of the equation. That's worth something, too. And, maybe you'll find a block as a big bonus.

Here's a copy of a post I made a few months ago. TLDR, you can make a profit in fiat while still being worse off in terms of BTC earned. "I bought a S19J Pro 13 months ago. Here's the numbers... I bought a S19J Pro Bitcoin miner to use as a garage heater in February 2023. I've been tracking its earnings on a spread sheet. It's had roughly 99% up time since I got it. I ran it overclocked for the majority of the time at 4000w and 125TH. In the summer months, I underclocked it at 1700w and 70TH. My residential electricity rate is right around $0.08 kWh. Here's the numbers using a current BTC price of $62,801 * I spent $2454.41 for the miner and everything I needed to get it up and running (control board for overclocking, wire, outlet, breaker, AC Infinity fan, fan shroud, etc.) * I spent a total of $2,434.56 in electricity. * Total expense = $4,888.97 * As of today, I earned 8,372,182 sats. That's worth $5,257.81. * Mining profit = $368.84 * If I were to sell the used equipment today, I'd get roughly $1,368.35 or 2,178,866 sats. * Total profit from mining and selling used equipment = $1,737.19 or 2,766,182 sats. * Total BTC accumulated = 10,551,048 sats worth $6,626.16 Not bad, right? I made $1737 over the course of a year while heating my garage. In USD, that's a net gain. However, if we do the math on BTC earned from mining vs. using the money spent on the equipment and electricity to buy BTC... * $2454.41 spent on the equipment in Feb 2023 would have bought approximately 10,751,441 sats. * $2,434.56 spent on electricity would have bought approximately 7,329,100 sats if I purchased BTC on the 1st of every month. * Total BTC from buying = 18,080,541 sats, worth $11,354.76. * Total profit buying BTC = $6,465.79 * Net loss from mining vs. buying = -7,529,493 sats or -$4,728.60 In my case, I would have made a lot more money and bitcoin if I just bought it. But I wouldn't have had a heated garage either. However, many of the months, I didn't need a heated garage and ran the miner anyway. :) Would I have paid to heat my garage without the miner? Probably not. Either way, I had fun tinkering with it. It was a great learning experience, and I'm still happy I did it. To those thinking about spending a large sum of money starting up a mining business, you seriously need to run the numbers. This situation would have worked out even worse if I bought more miners, infrastructure to support them, and had rent to house them. With the halving coming up in about a month, I will most likely become unprofitable and will be shutting down unless BTC doubles from here or difficulty drops."

# Dont feel Bad I Also Got Wrecked Mining Bitcoin with Compass Mining Alright folks, buckle up for a tale of woe and financial ruin. If you're thinking about mining Bitcoin, you might want to sit this one out and just HODL. In October 2022, I thought I was being smart. I dropped $79,500 on six shiny new Antminer S19XP 140 TH units, direct from Bitmain. Each one cost me $13,250. I figured with an all-in hosting fee of $0.065/kWh, I'd be rolling in Bitcoin. Spoiler alert: I was dead wrong. # The Initial Costs I forked out $56,312.50 upfront: * 65% of the hardware cost: $51,675 * First month’s installment: $4,637.50 * Hosting deposit for six machines: $873.38 (refundable after 12 months) * Hosting prepayment for six machines: $873.38 (first month covered) Then, I had monthly installment payments of $4,637.50 from July 2022 to November 2022. # The Delay from Hell Here's where things went off the rails. The first miner didn't come online until June 30, 2023. Yeah, you read that right. By the time all six were finally hashing, it was the end of 2024. What the actual \[expletive\]? # The Financial Sinkhole These miners were supposed to be my golden ticket. Instead, they turned into a financial black hole. Now, they're worth about $3,500 each. # The Hosting Nightmares Hosting invoices started stacking up as miners came online: * October 2022: $145.56 (1 miner) * November 2022: $291.13 (2 miners) * December 2022: $436.69 (3 miners) * You get the drift... # The Customer Service Dumpster Fire Compass Mining’s customer service is a joke. They didn't keep their promises, and their delays cost me big time. If there's a class action lawsuit against these clowns, count me in. # The Bottom Line I ended up with machines worth a fraction of what I paid and a huge chunk of BTC lost to electricity costs and depreciation. Mining Bitcoin turned out to be a dumpster fire of an investment. If you're thinking about mining, just don’t. Save yourself the pain and stick to buying and holding Bitcoin. Trust me, you'll sleep better at night. Don't make the same mistake I did. Learn from my disaster. Stay away from Compass Mining and think twice before jumping into Bitcoin mining.

They are still profitable.. run them on ultra low with custom firmware. They get down to 21w a TH which is the same as a s19XP. For reference stock is 34w a TH..

Not an idiot is a good way to stack. I have a T19 84th bumped to 90TH @ 3300Watts. I use Braiins pool and make around $3.70 a day. I'm going to miss those $7.00 days for sure. My electric is generally $7.98 a day but I feel its ok I get a low income discount. People say why not just DCA but I get introuble with my addictive personality and buy more then I should. Crazy as it sounds, mining helps me regulate that thrill of buying BTC.

I agree... I'll get as much out of my S19 XP 141 TH as possible and then re-evaluate. I find most people think of mining as profits like a business on a month to month basis. I think about it like stacking bitcoin for the future. So I pay the costs out my pocket with fiat, that is my bitcoin price. One day that mined btc will go up on value and justify the costs of today. I may be seeing things wrong but I get the feeling that lots of people aren't seeing the long-term vision. Or I'm an idiot

In my country it is, the machines cost $1,500 and currently produce $230 per month. In the United States the machines cost $800 depending on how many TH they are.

You can actually work out how much power that was consumed from the block itself. First, get the target of the block. A 256-bit value that the nonce the miners are brute-forcing must be lower than. This is the value that gets set every 2 weeks, as part of the difficulty adjustment, so each block takes approx. 10 mins to mine. In the case of block 841395, the target was 386085339 (or 0x170331db). Then you split the target into 2, the first bit is your exponent (0x17) and the second bit is your coefficient (0x0331db - You need to prefix with 0x). The target representation is therefore: target = coefficient * 2 ** (0x08 * (exponent - 0x03)) For block 841395, that was: 0x331db0000000000000000000000000000000000000000 An Antminer S21 can do 17.5 joules per terahash (J/TH). joules_per_terahash = 17.5 # An Antminer S21 consumes 17.5 Joules per terahash joules_per_block = (2 ** 256 / target) / 10 ** 12 * joules_per_terahash kwh_per_block = joules_per_block * 2.7777778 * 10 ** -7 Therefore, we can convert the joules consumed to kW's to approximate the amount of energy consumed in the creation of the block. In this example, it was 1,839,495 kW. The price of power is extremely diverse, ranging from 0p to 0.10p/kWh (maybe more?). The network self-balances itself by having miners turn off once unprofitable. I think it's fair to assume that the average Bitcoin miner is operating around 0.05p/kWh (this is a guess). Excluding tx fees, 3.25 BTC were paid out. Therefore, if we divide the tota amount of power used to mine the bitcoin by 3.25, we get the amount of kWh/BTC = 695,370. Then we multiply this by 0.05p = £28,300. So, excluding tx fees, 1 BTC has a basement power input price of £28,300, based on information baked into the block itself. Hope this was useful. Comments and discussion are helpful.

500 Sats takes about 2-4 days running a BTC miner at 2TH/s. Put it in that perspective.

The beauty of BTC is that we can know with precise accuracy how much energy it uses because we know the hash rate and how much energy miners use per TH/s on average. Big banks are a black box. Even if BTC did use more electricity per transaction, there is zero transparency in conventional banking, so we can'tactually know. BTC can also be altered by concensus of the network to be more efficient if this turns out to be important.

Wait a minute. There have only been 282 non-pool mined blocks in the history of Bitcoin? There's no way in hell that's true. In the early days there were TONS of people solo mining. I'd be willing to bet there have been 282 solo blocks solved on ckpool.... Fun fact. I solved a block on CKPool in 2017 :) I had 256 TH/s running at the time. The difficulty of the solve was over 7 Trillion with a required dififculty of ~5 Trillion. I fell out of my chair when I was looking through my miners in Awesome Miner to see the biggest solve submitted to the pool and "Number of blocks solved" equaled "1" The pool runner gives a reward to the person who solves the block. I believe it was .25 BTC. He also gave me a free license for AwesomeMiner to use with my GPU machines. Apparently he had a hand in writing that software.

120 TH/s is about 3kW. 120PH/s would be 3MW. That's only like 3000 family homes.

Why are all antminers like the 19 series still ridiculously high? My T19 is basically worthless $3.00 a day but sells for $500 and who the hell wants to spend $1800 for a 120TH model that makes .50 cents more? Then there are the used 200TH models for $4500 thats just stupid. Ebay still trying to sell used S9 models for $200 LOL. Ebay sellers are a joke.
