Mining bitcoin in college (free electricity!)

I am working with a friend to set up a bitcoin mining rig our university. I'm a business major, but my friend is in engineering and has unlimited free access to a 220v power supply. Would it be worth buying 100 AntMiner S9's on eBay and making our own rig?
The math breaks down as follows according to https://www.cryptocompare.com/mining/calculatobtc?HashingPower=1350&HashingUnit=TH%2Fs&PowerConsumption=137500&CostPerkWh=0&MiningPoolFee=1
1350 TH/s hashrate (with 100 S9s at 13.5 TH/s for each unit)
Electricity cost is zero.
Predicted payout is $3,390/month.
Am I missing something? It seems too good to be true, making 4k/month with only 10k up front.

EDIT: Assume the rig was well hidden and not discovered for a few years.

Antminer T19 May Not Affect Bitcoin Hash Rate but Keeps Bitmain Ahead

The Antminer T19 by Bitmain may not have a big impact on the Bitcoin network, and it comes out amid the firm’s internal and post-halving uncertainty.
Earlier this week, Chinese mining-hardware juggernaut Bitmain unveiled its new product, an application-specific integrated circuit called Antminer T19. The Bitcoin (BTC) mining unit is the latest to join the new generation of ASICs — state-of-the-art devices designed to mitigate increased mining difficulty by maximizing the terahashes-per-second output.
The Antminer T19 announcement comes amid the post-halving uncertainty and follows the company’s recent problems with its S17 units. So, can this new machine help Bitmain to reinforce its somewhat hobbled position in the mining sector?
T19: The cheaper S19
According to the official announcement, the Antminer T19 features a mining speed of 84 TH/s and a power efficiency of 37.5 joules per TH. The chips used in the new device are the same as those equipped in the Antminer S19 and S19 Pro, though it uses the new APW12 version of the power supply system that allows the device to start up faster.
Bitmain usually markets its Antminer T devices as the most cost-effective ones, while the S-series models are presented as the top of the line in terms of productivity for their respective generation, Johnson Xu — the head of research and analytics at Tokensight — explained to Cointelegraph. According to data from F2Pool, one of the largest Bitcoin mining pools, Antminer T19s can generate $3.97 of profit each day, while Antminer S19s and Antminer S19 Pros can earn $4.86 and $6.24, respectively, based on an average electricity cost of $0.05 per kilowatt-hour.
Antminer T19s, which consume 3,150 watts, are being sold for $1,749 per unit. Antminer S19 machines, on the other hand, cost $1,785 and consume 3,250 watts. Antminer S19 Pro devices, the most efficient of three, are considerably more expensive and go for $2,407. The reason Bitmain is producing another model for the 19 series is due to what is known as "binning" chips, Marc Fresa — the founder of mining firmware company Asic.to — explained to Cointelegraph:
“When chips are designed they are meant to achieve specific performance levels. Chips that fail to hit their target numbers, such as not achieving the power standards or their thermal output, are often ‘Binned.’ Instead of throwing these chips in the garbage bin, these chips are resold into another unit with a lower performance level. In the case of Bitmain S19 chips that don’t make the cutoff are then sold in the T19 for cheaper since they do not perform as well as the counterpart.” The rollout of a new model “has nothing to do with the fact that machines are not selling well,” Fresa went on to argue, citing the post-halving uncertainty: “The biggest reason machines probably are not selling as well as manufacturers would like is because we are on a bit of a tipping point; The halving just happened, the price can go anyway and the difficulty is continuing to drop.” Product diversification is a common strategy for mining hardware producers, given that customers tend to aim for different specifications, Kristy-Leigh Minehan, a consultant and the former chief technology officer of Genesis Mining, told Cointelegraph:
“ASICs don’t really allow for one model as consumers expect a certain performance level from a machine, and unfortunately silicon is not a perfect process — many times you’ll get a batch that performs better or worse than projected due to the nature of the materials. Thus, you end up with 5–10 different model numbers.” It is not yet clear how efficient the 19-series devices are because they have not shipped at scale, as Leo Zhang, the founder of Anicca Research, summed up in a conversation with Cointelegraph. The first batch of S19 units reportedly shipped out around May 12, while the T19 shipments will start between June 21 and June 30. It is also worth noting that, at this time, Bitmain only sells up to two T19 miners per user “to prevent hoarding.”
Hardware problems and competitors
The latest generation of Bitmain ASICs follows the release of the S17 units, which have received mostly mixed-to-negative reviews in the community. In early May, Arseniy Grusha, the co-founder of crypto consulting and mining firm Wattum, created a Telegram group for consumers unsatisfied with the S17 units they purchased from Bitmain. As Grusha explained to Cointelegraph at the time, out of the 420 Antminer S17+ devices his company bought, roughly 30%, or around 130 machines, turned out to be bad units.
Similarly, Samson Mow, the chief strategy officer of blockchain infrastructure firm Blockstream, tweeted earlier in April that Bitmain customers have a 20%–30% failure rate with Antminer S17 and T17 units. “The Antminer 17 series is generally considered not great,” added Zhang. He additionally noted that Chinese hardware company and competitor Micro BT has been stepping on Bitmain’s toes lately with the release of its highly productive M30 series, which prompted Bitmain to step up its efforts:
“Whatsminer gained significant market share in the past two years. According to their COO, in 2019 MicroBT sold ~35% of the network hashrate. Needless to say Bitmain is under a lot of pressure both from competitors and internal politics. They have been working on the 19 series for a while. The specs and price look very attractive.” Minehan confirmed that MicroBT has been gaining traction on the market, but refrained from saying that Bitmain is losing market share as a result: “I think MicroBT is offering option and bringing in new participants, and giving farms a choice. Most farms will have both Bitmain and MicroBT side by side, rather than exclusively host one manufacturer.”
“I would say that MicroBT has taken up the existing market share that Canaan has left,” she added, referring to another China-based mining player that recently reported a net loss of $5.6 million in the first quarter of 2020 and cut the price of its mining hardware by up to 50%.
Indeed, some large-scale operations seem to be diversifying their equipment with MicroBT units. Earlier this week, United States mining firm Marathon Patent Group announced that it had installed 700 Whatsminer M30S+ ASICs produced by MicroBT. However, it is also reportedly waiting for a delivery of 1,160 Antminer S19 Pro units produced by Bitmain, meaning that it also remains loyal to the current market leader.
Will the hash rate be affected?
Bitcoin’s hash rate plummeted 30% soon after the halving occurred as much of the older generation equipment became unprofitable due to the increased mining difficulty. That spurred miners to reshuffle, upgrading their current rigs and selling older machines to places where electricity is cheaper — meaning that some of them had to temporarily unplug.
The situation has stabilized since, with the hash rate fluctuating around 100 TH/s for the past few days. Some experts attribute that to the start of the wet season in Sichuan, a southwest Chinese province where miners take advantage of low hydroelectricity prices between May and October.
The arrival of the new generation of ASICs is expected to drive the hash rate even higher, at least once upgraded units become widely available. So, will the newly revealed T19 model make any impact on the state of the network?
Experts agree that it won’t affect the hash rate to a major degree, as it’s a lower output model compared with the S19 series and MicroBT’s M30 series. Minehan said she doesn’t expect the T19 model “to have a huge impact that’s an immediate cause of concern,” as “most likely this is a run of <3500 units of a particular bin quality.” Similarly, Mark D’Aria, the CEO of crypto consulting firm Bitpro, told Cointelegraph:
“There isn’t a strong reason to expect the new model to significantly affect the hashrate. It might be a slightly more compelling option to a miner with extraordinarily inexpensive electricity, but otherwise they likely would have just purchased an S19 instead.” Bitmain continues to hold leadership despite internal struggle
At the end of the day, manufacturers are always in an arms race, and mining machines are simply commodity products, Zhang argued in a conversation with Cointelegraph:
“Besides price, performance, and failure rate, there are not many factors that can help a manufacturer differentiate from the others. The relentless competition led to where we are today.” According to Zhang, as the iteration rate naturally slows down in the future, there will be more facilities using “creative thermal design such as immersion cooling,” hoping to maximize the mining efficiency beyond just using most powerful machines.
As for now, Bitmain remains the leader of the mining race, despite having to deal with the largely defunct 17 series and an intensifying power struggle between its two co-founders, Jihan Wu and Micree Zhan, which recently resulted in reports of a street brawl.
“Due to its recent internal issues, Bitmain is facing challenges to keep its strong position in the future thus they started to look at other things to expand its industry influences,” Xu told Cointelegraph. He added that Bitmain “will still dominate the industry position in the near future due to its network effect,” although its current problems might allow competitors such as MicroBT to catch up.
Earlier this week, the power struggle inside Bitmain intensified even further as Micree Zhan, an ousted executive of the mining titan, reportedly led a group of private guards to overtake the company’s office in Beijing.
Meanwhile, Bitmain continues to expand its operations. Last week, the mining company revealed it was extending its “Ant Training Academy” certification program to North America, with the first courses set to launch in the fall. As such, Bitmain seems to be doubling down on the U.S.-based mining sector, which has been growing recently. The Beijing-based company already operates what it classifies as “the world’s largest” mining facility in Rockdale, Texas, which has a planned capacity of 50 megawatts that can later be expanded to 300 megawatts.

Building a mining rig for 100k USD.

Ok so basically my question is this:
How do you build the most efficient Bitcoin mining rig with 100k USD?
I've been trying to do some research but I really want some info from people who have/have had mining rigs in the past. I wanna know what are some potential issues that could arise?
I want to know if it's most cost effective to buy a bunch of GPU's and set them up with some mining motherboards or is it better to buy a pre-built machine like the AntMiners?
If I'm building a rig for 100k and plan to pay for electricity using the bitcoin mined each month then how much money do I need to have as backup to make sure I can pay for electricity if BTC price drops significantly?
Just anything useful that someone who plans to build a rig should account for.
Also: Yes I acknowledge that BTC is very unstable and that even though mining right now (for 10K/BTC) is profitable it could be the case that later on I'm mining in the negative for several months or years.
Thanks.

A 14-year-old's experience with Bitcoin

First-time poster here, don’t bully me, apologies for the potentially atrocious formatting :) TL;DR at the end
So in the wake of Bitcoin’s explosive rise in value and media attention, I’ve been encouraged by others to share my experience over the past few years as a miner. Here's my story (it's kinda long, you've been warned)

Humble Beginnings

It all started almost three years ago in the beginning of 2015 when Bitcoin flew under my radar. Looking into it, I admittedly wasn’t drawn in because of the decentralisation or the anonymous payments, I was hooked on the idea that anyone could get their hands on some just by running a program and leaving it to do its own thing. I know, how shallow of me. But the idea of making even a bit of money without ‘any work’ was convincing enough for 11-year-old me to do more digging into the matter.
To my disappointment, I soon found out that the era of mining Bitcoins with a PC’s CPU or GPU was long obsolete and instead it was all ASICs at that point.
So that summer, for my twelfth birthday, I got a little ASIC machine for €60, an Antminer U3. This little thing took up less space than a graphics card but could mine at 60 GH/s. Because, at the time, I didn’t have a controller device that could be kept up and running all day long so it could run the program that mined Bitcoin using the U3, I went ahead and got a Raspberry Pi. After setting up the Pi and installing all the necessary stuff (took an awfully long time), I connected it to AntPool and plugged the U3 in. Two days past and the mining pool sent the first Bitcoin I ever received to my wallet (I was using Blockchain.info). It was just 30 cents worth of BTC but I felt a bit of a rush because I was earning a bit of money through this completely new thing and the idea of that was thrilling.
Let’s back up for a second. I just used the term ‘earning’ as if I was profiting, and naive me 2 years ago was no different. In reality, I was at first oblivious to the fact that I was most likely LOSING money overall because of how much energy that little sucker was taking in. But, I was comforted thinking that using that machine was just a practical way of learning about this modern currency and that the loss of several cents’ worth of energy was acceptable in the name of education and learning.
Fast forward ten months to the wonderful summer of 2016. I had recently turned 13 and the Antminer U3 had been running on and off throughout. Various pauses and breaks in mining would be observed, as I had to manually get everything up and running after frequent breaks in the Internet connection. You’d expect my newly-turned-teenage brain to lose interest in Bitcoin as it does with many other gimmicks, but – even surprising myself – I miraculously didn’t. Good thing I maintained interest thinking about it now, not so good at the time for my parents. Why do I say this? I felt like it was time to get a little upgrade in my hardware.

Getting an upgrade

Days passed with me comparing every ASIC miner I could at that price point. It was then I set my eyes upon the Antminer S7 (same folks who did my U3, nice). I had put it up against a plethora of other miners and I figured the S7 was my best bet; the thing costs only about 10 times that of my U3 but could run at 4.73 TH/s, almost 80 times as powerful. The only problem being its power consumption was at 1300 watts, which would put a massive dent in the electricity bill and eliminate any profit I would make. Fortunately, I had a secret weapon up my sleeve – or rather my mum did. She had rented out an office outside our apartment where she would keep files and paperwork. The office’s electricity bill was a flat rate as far as I’m aware and it ended up being my saving grace because it virtually got rid of the “oh no I’m actually going to be losing money because of how much electricity I’m eating up” factor, making this whole hardware upgrade viable.
After convincing my parents, they finally agreed to shell out the requested amount, with the initial investment being paid back with time. I went to a local Bitcoin vendor and purchased 1 BTC for about $665 in cash (sigh yes, I know. $665 dollars). Shortly after, I used about 0.9 BTC to purchase the Antminer S7 and a 1600W power supply for a grand total of $600. The products would be made and shipped from China so I was definitely in for a wait.
A month passes and the package arrives at last. I connected all the wires from the power supply into the S7 and – with great anticipation – I plugged it into the wall to start its first ever run. And what do you know? An extremely loud and high-pitched whirring sound blasted out from the fans on both the power supply as well as the S7. After killing the thing, I questioned my choices. I couldn’t dare put that thing anywhere near my mum’s office in the event it drive everyone in the building absolutely nuts. I was at a loss. However, I soon recovered from my temporarily debilitated state and got working on a solution.
The first idea that came to my mind: change the fans. The stocks fans were by Evercool and spun at around 3000 RPM. The power supply used a small, robust fan that looked like a cube that must’ve spun at extremely high speeds judging by how high the sound it produced was. I got my parents to give me some more funding so I could acquire the replacement fans and I did. Bust. After installation and testing, none of the fans would work. I managed to configure the S7 to connect to my Antpool account and the machine would manage mining for several minutes running at peak performance but ultimately be automatically cut off because of how hot the machine was getting (I’m talking about 80 degrees Celsius kinda hot in that thing). The fans got refunded and I was back to the drawing board.
After combing through some forum posts and videos, I came across this video and a forum post in which people have their mining rigs placed inside a ventilated, muffled cabinet. Undertaking a project like this would be time-consuming and risky but I had no better ideas so I decided to go through with the idea anyway.
Firstly, I sought out a cabinet with suitable dimensions. I managed to get just what I needed at a second-hand IKEA shop. Great. Secondly, I went ahead and acquired some sound-absorbing acoustic foam from a local provider. Fantastic. Finally I had to get a ventilation system going within the cabinet, otherwise, all the hot air would roast the machine alive in there in a bloody mess. With the help of my dad, we found a pair cabinet fans on the Internet that were close to silent but could circulate the air well enough.
Eventually, all the materials came and, with the help of my parents, put everything together. The process took quite long time and we had a couple hiccups along the way, but we got it done and it came out pretty nice.
The moment of truth came and, to my relief, it ran so much quieter than without the cabinet. It was nowhere near silent but it reduced the noise a great deal. Soon after, I got the thing into the office and set everything up from there. Unfortunately, I was forced to underclock it because you could still hear the machine’s whining from outside the thin office door. Gunning the hashrate down about 25% to 3.7TH/s, I could lower the fan speed without risking the machine burning up. Sure, I wasn’t getting the full potential of the machine but I didn’t complain because electricity was not an issue there and it was still a whole lot better than my U3. With it up and running, I could leave it there, periodically checking to see if it was mining on Antpool.

The aftermath

In the months that followed, I was getting a solid $2.5 worth of BTC on daily basis. Half a year later, May of 2017, I had accumulated a satisfactory $600. I thought, “At this rate, I’d be able to pay my parents’ investment back in a few months” (the total investment came close to $900). Bitcoin had risen to over $1500 so I was already over the moon at that point because of how well everything was going. Little did I know…
I hit 0.5 BTC midway through September this year. The price of BTC had dropped after a sudden rise to $5000, but I couldn’t have asked for more. Although I possessed only half the amount of BTC I paid for the machine, its value was over twice that of the initial investment. I thought BTC would level off at around $4000 but nope.
In the month of October, the price skyrocketed. Since September, I had only mined 0.017 BTC but the value was already over $3000. It was just a matter of selling it, but I decided to hodl. Good thing I did.
As of November 5, I have approximately 0.52 BTC mined in total from my S7, valued at $4000. If I were to sell it right now, I’d have a profit of over $3100. And as for my miner, it’s churning out 0.0006 BTC daily, sounds like nothing but it’s still the equivalent of $5 today and I couldn’t be happier, at least with the miner and Bitcoin.
You remember that $665 for 1 BTC that I mentioned earlier? In hindsight, it would’ve been such a better idea to just keep that one Bitcoin and not do anything with it until today (in the interest of making much more money), as I’d theoretically have upwards of $7000. The idea of that still haunts me sometimes if I dwell on it too long but knowing that I’m in possession of an already hefty amount, the pain of it had numbed slightly. It’s not all doom and gloom for me from the exponential increase in Bitcoin’s value, however. Those first $0.3 payments from my humble little U3 all those years ago now are now the equivalent of over $6 today!
Bitcoin and everything it encompasses has been and still is a journey of discovery and an adventure. Looking back, starting with a modest €60 Antminer U3 to having a sum of Bitcoin equivalent to two extremely high-end gaming rigs (first thing I could think of as a comparison, sorry) has been something I can’t really describe. Through the course of the past few years, I’ve learned more about technology, I’ve unexpectedly gotten insight into economics and business and – of course – I’ve made a lot of money (if I decide to stop hodling that is).
Also, props to my parents for keeping an open mind throughout, I know some parents would be horrified at their kids being involved in something that has been used in some less-than-savoury ways and it's great knowing mine have been supportive all the way.
TL;DR got into Bitcoin mining 3 years ago at age 11 with an Antminer U3 that ran at 60 GH/s, got an Antminer S7 (4.73TH/s) and built a sound-muffling, ventilated cabinet for it. Am sat here today with $3000 profit if I decide to sell right now.

Why is GPU Bitcoin mining all of a sudden so popular again?

I see people popping up with mining rigs made entirely of GPUs and I cannot get an answer anywhere. Last i heard the difficulty was so high that an ant miner could get you more hash an hour than a GPU could a day.
Has the difficulty dropped - if so why? Last i saw bitcoins were worth about $1,000 a pop and that was less than 2 weeks ago (I believe)

Building mining rig

Hi guys!
Me and two other friends are thinking about getting into the mining business.
We’ve read us up a little bit, but I’d say we’re pretty much still in the “nooby”-phase. Our train of thought was that we’re too late for the party regarding mining bitcoin, so we decided to go for the more “underdog” – Litecoin(?)
We’ve read a little bit about it, and understood that we need powerful GPUs for the mining, while the CPU can be low budget.
The plan is to start of with building a rig for around 6000$/5400€. If things go well - by that I mean If we are to mine Litecoins well worth the money, the plan is to expand it with more rigs.
Here is a list I thought would be powerful enough for the first rig, but I haven’t looked at “bang-for-the-buck”, or specific items that’s especially good for this type of mining, if there is any?
Motherboard - ASUS ROG Maximus IX Apex, Socket-1151
CPU – Intel Pentium G4400 Skylake (randomly picked a cheap one I found.)
RAM – HyperX Fury DDR3 1866MHz 16GB (Do this need to be high-end?)
GPU - 4x INNO3D GeForce GTX 1080
PSU - EVGA GQ 1000W Hybrid Modular 80+ PSU
HDD – Random 500GB HDD (whatever I find that works.)
Couple of questions:
Thank you so much in advance, I know there’s a lot of questions, and I’d be more than happy and grateful if any of you took your time to even answers half of them!

Introducing Block Town: Using Bitcoin Mining for Sustainable Living

Hey y'all, I've been mulling over an idea I've had for some time, and I wanted to share it with the community for feedback, ideas, insights, and whatever else it inspires you to think.
I call it Block Town, and don't worry--I'm not shilling an ICO. It would be a sustainable living community model that's centered around Bitcoin mining.
"Lol dude wtf btc mining is the farthest thing from sustainable." Exactly. That's why I want to turn something that's becoming an environmental issue into one that cuts back on waste with three simple ingredients: micro homes, ASIC miners, and solar panels.
The Home Each home would be roughly 300-500 square feet, depending on the number of residents. Each home would come equipped with a solar paneled roof and a Bitcoin mining setup replete with AntMiner S9s. I haven't hashed out (seriously no pun here) the number of miners per home, but I'm leaning towards something like 5. As you can probably guess, the miners will draw their energy from the panels, in effect neutralizing mining energy consumption.
The miners would, in turn, serve a few roles. 1) They would provide heating for the house, 2) they would provide heating for the house's water supply, and 3) they would provide funding for the community, its residences, and the property owner.
Mining Profit Allocation If each house comes with 5 AntMiner S9s, I've estimated that this will net $20,000 in income for the house a year (give or take--this is a rough estimate). Profits from each house will be divided as follows: * 20% to the resident of the house * 20% to a community fund * 20% for maintenance of the mining systems * 40% to the landlord If the resident can maintain his/her own system, the maintenance fee is cut in half and they will be able to keep this 10% (the reason to still take 10% is to make sure there is enough money for the community's complete maintenance).
The Benefits of This System With a system like I just described, you could effectively mine Bitcoin with 0 energy costs while also using the excess heat from the miners to heat both the home and its water supply. I believe that this model has the potential to provide low-cost heating solutions while also giving residence the potential to earn passive income. Moreover, the community fund can be used for any number of initiatives--Block Town has the potential to grow into a full scale cooperative living community if its residents wish to take it there.
A few challenges: start up costs, maintenance, reliable sunlight. To solve the later, I've thought that a great launching place would be New Mexico, Arizona, Nevada, or Texas. With these, however, comes the danger of overheating systems, but climate control measures (e.g., placing the rigs underground, insulating them inside the house) can be implemented.
So what do you guys think? I want honest opinions, why it will work, why it won't work, obstacles I haven't looked into, insights to improve the model, anything. The thought that I could actually make this a reality gets me juiced-up. I'm committed to making this happen, because I believe a system like this could actually make for sustainable living and, on a mass scale, possibly make mining sustainable, too.

Is it worth it to start a rig these days?

Looking and feeling like I'm a couple of months/years behind things, but at this point, would it still be worth it to build a mining rig and start mining at a higher level from the basic single machine and GPU generating a couple dollars a day now?
Complexity will only get worse from this point but with a descent rig, the ROI should only be a couple of months before it's basically printing money at a nice rate. If bitcoin drops in value (heaven forbid a price crash), these rigs can be used to mine other coins for growing values.
The other thought about mining rigs, instead of building one, would be an investment into something like an AntMiner. But that'll put me into a corner of only mining one particular coin, and when it's done, it's done. Correct?

Profitable Mining Rig 2017

I found a profitable Bitcoin ASIC miner (AntMiner S9) But I don't want to mine Bitcoin because of the difficulty I'm afraid in a short time this miner won't be profitable anymore. I was wondering if anyone knows of or has built a profitable Dogecoin Mining rig?
Much Thanks, Such Knowledge, Wow Thanks,

USB Bitcoin mining worth doing ?

HI, I just start bitcoin mining for a week with my single rx480 using NiceHashMinier. I am very interested with USB bitcoinmining. I want to build a small USB mining rig with raspberry pi or AntMiner U3 because it I dont have much space for a mining rig. I have a bugdet around $100 and I just wonder if it is worth doing ?

Am i missing something or am i good to go?

Ok so for quite some time now i've been thinking about investing in a miner. I've heard everywhere that now it's too late unless you want to invest 10s of thousands of dollars. But i was still sceptical as to why and did quite some reasearch and put in the appropriate stats: https://www.coinwarz.com/calculators/bitcoin-mining-calculato?h=4730.00&p=1293.00&pc=0.10&pf=1.00&d=1123863285132.97000000&r=12.50000000&er=5628.66150000&hc=635.00
It definitly suggest i'll make profit, and pretty damn fast too. I live in a pretty large house in sweden, so cooling shouldn't be a problem since rn it's about 0c degrees in the morning and it'll only get colder. Electricity costs are quite standard and noise is not at all. I'm thinking of buying an Antminer S7, although i suppose it would be difficult to find it + a powersupply for the price tag i put on it (635 dollars), but i did find this: http://www.ebay.com/itm/1600W-ATX-Mining-Power-Supply-SATA-6-GPU-Bitcoin-BTC-Rig-Ethereum-Miner-S7-/112496276815 http://www.ebay.com/itm/Bitmain-AntMiner-S7-4-7TH-s-Bitcoin-Miner-ASIC-WORK-GOOD-No-PSU-/222676802534?hash=item33d8925be6:g:HtoAAOSw62VZwcxg
So i just want to ask am i golden or have i missed a vital piece of information? I know mining will get harder over time but the bitcoins are also rising, and oh also what's the risk? I mean the bitcoin price has a risk of collapsing any moment.

How much of a difference would 13,774 average computers make mining for XT pools?

Edit: Apparently, even if we all had high end graphics cards, the answer is "effectively no difference". If, however, we all invested in a bitcoin miner ASIC (even a low end one), that could make a difference.
I'm going to pick one up from here unless anyone has any better suggestions: http://smile.amazon.com/Bitmain-AntMiner-Bitcoin-Miner-Version/dp/B00TWK9208?sa-no-redirect=1
Looks like older ASICs (which are cheaper but less energy efficient) are the best option if we're willing to mine at a loss: http://smile.amazon.com/AntMiner-S3-441Gh-0-77W-SHA-256/dp/B00NZDBWKG?sa-no-redirect=1
It's also been pointed out that gpu and cpu mining is more profitable on altcoins and so, if we were to all mine one of them, we could then donate the proceeds to cloud mining on an XT pool.
There are 13,774 subscribers to this subreddit. Even though the vast majority of us don't have hardware that would be cost effective for mining, I think many of us would be willing to mine at a loss just to show support for XT.
While, of course, one mediocre mining rig wouldn't make a noticeable difference, what about a ton of us?
Cheers!

How do multiple mining rigs work relating to earnings?

I really hope this is the right place to post this. I tried to find another subreddit specifically about mining, but nothing showed. Maybe I didn't look enough.
Anyways, thanks to the crazy price increase, I now have enough money to buy about 4 AntMiner S9's. I heard this was the best one around, correct me if I am wrong please.
Basically, back in 2015 when I had enough bitcoin to make me a millionaire in todays rate (so happy about that), I remember being pretty fluent in the whole mining setup with independent vs pool mining. I don't remember much anymore. However, I do remember that one is better if you are mining with something more powerful and one is better if you are mining just with a computer (I believe this was the pool).
So TDLR theoretically if I had 4 of those AntMiners and was mining a block independently would I make more than if I mined with a pool? This was something to do with block shares I think? And is 4 miners a notable amount at all? Everything I have found about mining says it's not profitable anymore, but then why are organizations mining with buildings full of rigs?
I'm sure I can figure out something with the electricity issue too. Hell, I could have a big windmill in my front lawn, why not. Curb appeal if I decide to sell the house right?

How should I invest in bitcoin?

Hi I’m looking to get into bitcoin and I have around $1500 to spend, I’m fairly new to the crypto currencies although I have been buying and selling in lite coin for about a month. My question is should I invest in a nice mining rig like an ant miner s9? Or should I put my money straight into bitcoin?

[uncensored-r/CryptoCurrency] Introducing Block Town: Using Bitcoin Mining for Sustainable Living

The following post by LeDoduSuisse is being replicated because some comments within the post(but not the post itself) have been openly removed.
The original post can be found(in censored form) at this link:
np.reddit.com/ CryptoCurrency/comments/7uvk8f
The original post's content was as follows:
Hey y'all, I've been mulling over an idea I've had for some time, and I wanted to share it with the community for feedback, ideas, insights, and whatever else it inspires you to think.
I call it Block Town, and don't worry--I'm not shilling an ICO. It would be a sustainable living community model that's centered around Bitcoin mining.
"Lol dude wtf btc mining is the farthest thing from sustainable." Exactly. That's why I want to turn something that's becoming an environmental issue into one that cuts back on waste with three simple ingredients: micro homes, ASIC miners, and solar panels.
The Home Each home would be roughly 300-500 square feet, depending on the number of residents. Each home would come equipped with a solar paneled roof and a Bitcoin mining setup replete with AntMiner S9s. I haven't hashed out (seriously no pun here) the number of miners per home, but I'm leaning towards something like 5. As you can probably guess, the miners will draw their energy from the panels, in effect neutralizing mining energy consumption.
The miners would, in turn, serve a few roles. 1) They would provide heating for the house, 2) they would provide heating for the house's water supply, and 3) they would provide funding for the community, its residences, and the property owner.
Mining Profit Allocation If each house comes with 5 AntMiner S9s, I've estimated that this will net $20,000 in income for the house a year (give or take--this is a rough estimate). Profits from each house will be divided as follows: * 20% to the resident of the house * 20% to a community fund * 20% for maintenance of the mining systems * 40% to the landlord If the resident can maintain his/her own system, the maintenance fee is cut in half and they will be able to keep this 10% (the reason to still take 10% is to make sure there is enough money for the community's complete maintenance).
The Benefits of This System With a system like I just described, you could effectively mine Bitcoin with 0 energy costs while also using the excess heat from the miners to heat both the home and its water supply. I believe that this model has the potential to provide low-cost heating solutions while also giving residence the potential to earn passive income. Moreover, the community fund can be used for any number of initiatives--Block Town has the potential to grow into a full scale cooperative living community if its residents wish to take it there.
A few challenges: start up costs, maintenance, reliable sunlight. To solve the later, I've thought that a great launching place would be New Mexico, Arizona, Nevada, or Texas. With these, however, comes the danger of overheating systems, but climate control measures (e.g., placing the rigs underground, insulating them inside the house) can be implemented.
So what do you guys think? I want honest opinions, why it will work, why it won't work, obstacles I haven't looked into, insights to improve the model, anything. The thought that I could actually make this a reality gets me juiced-up. I'm committed to making this happen, because I believe a system like this could actually make for sustainable living and, on a mass scale, possibly make mining sustainable, too.

12-10 23:33 - 'Lets have a discussion about energy consumption in bitcoin mining and what that means towards the carbon footprint today.' (self.Bitcoin) by /u/Cryptolution removed from /r/Bitcoin within 1-11min

'''
There was a [very good coindesk article in July 2014]1 that broke down the carbon footprint of the bitcoin mining network. At the date of the article, our hashrate was 146,505 TH/s. Now that we are at above 13 exahashes/s this represents a 94 fold increase hashing power.
[Here is the cost breakdown chart from the coindesk article]2 .
As you can see from this image, the carbon footprint of bitcoin in 2014 is a tiny fraction compared to the carbon footprint of the traditional banking system. Yet at a 0.78 Billion per year cost in 2014, at a 94 fold increase of power that would now be 73.32 billion, which would make bitcoin 9.52 billion more in electricity costs.
But this is trying to extrapolate data in a non-accurate way. In order to understand why this is inaccurate, we must look at how all of this technology works and how technology has scaled upwards while decreasing electricty consumption.
The bitcoin network at 13 exahashes is roughly 130 times greater than the largest super computer (Sunway, 93 petahashes per sec in china, see [top500.org]3 )
So when you make that statement, you think "wow, bitcoin must use a lot of energy to be 130 times more powerful than the largest super computer network!"
But, its not apples to oranges. These super computer networks are non-specialized hardware (comparably to bitcoin) in that they have generalized computing capabilities. This means that these systems require more standardized hardware so that they can preform a large amount of different computing functions.
So, for example, the largest Sunway supercomputer @ 93 petaflops (roughly 1/130th the power of the bitcoin network) preforms its calculations at 93,014.6 petahashes @ 15,371 kW = 93014000 Gh @ 15370000 watts. Doing the maths, this comes out to a 0.16524 W/Gh.
The AntMiner S9 currently operates at 0.098 Gh ....so nearly double the energy efficiency of what the most powerful super computer network in the world operates at.
You have the Dragonmint miner coming out Q1-Q2 in 2018 which uses 0.075J/GHs ....a 30% efficiency increase over the Antminer S9.
And next year japanese giant GMO is launching into the bitcoin mining business, stating they will be releasing a 7nm ASIC design, which is more than double the efficiency of the current 16nm design the Antminer S9 uses. This will mean a more than doubling of energy efficiency. They said they have plans after the release of the first product to research "5nm, and 3.5nm mining chips"
So, what is the point of understanding all of this? Well, you have to understand how technology scales (think Moore's law) to understand how we can achieve faster computational speeds (more exahashes per second) without increasing the carbon footprint.
So if you look at a proof of work chart, you'll see it has scaled linearly upwards since the birth of bitcoin. And it would be logical to assume that the more hashes per sec thrown into the network, that it would equate to more power being spent. Yet this is not true due to advancements in ASIC chip design, power efficiency, and basic economic fundamentals.
You see, as new miners come out, because they are more efficient, people can run much faster mining rigs at much lower cost. This immediately adds much more hashing power to the network, which decreases the profitability of old miners. And to give you an idea of how much more cost efficient these are, lets look at Antminers products.
S9 - 0.098 W/Gh
S7 - 0.25 W/Gh
Avalon6 - 0.29 w/Gh
You can see the S9 is 3 times more power efficient than the Avalon6. That translates to "It costs 3 times more to operate this equipment". That aint no small difference.
These differences, combined with energy costs are what forces miners to stop running old hardware and to upgrade to newer models or exit mining completely. So as new mining equipment hits the market, old less efficient mining rigs go offline. The amount of hashes per sec continues to climb, yet the actual power usage of the entire network does not scale at the same rate that the hashes per sec scale at, due to increased energy efficiency.
The question that I would like to see answered by the community is this -
What has changed between now and 2014 in terms of total watts consumed? How can we calculate the real carbon footprint of todays bitcoin mining network compared to this data from 2014?
What equipment was running in 2013-2014, what were their W/Gh and how many of these machines do we speculate are still running vs more efficient mining rigs powering the network today? What is the Th/S differences between these mining rigs, and how much more power do we contribute towards the network today because of these optimized rigs?
Mining is not my specialty and there are going to be many people here who are better suited to tackling these problems.
I think these questions need to be answered and articulated because these are questions that im starting to see a lot from the mainstream as criticism towards bitcoin. I know the generic answer, aka "Bitcoin mining still uses a fraction of the cost that the entire global banking system does", but we really need to do better than that. We need to examine the different power types used in bitcoin mining -
How much of bitcoin mining is from hydroelectric? Nuclear? Wind? Solar? Coal? Natural Gas? What regions contribute the largest hashing power and can we evaluate whether these regions are Hydroelectric, Coal, Nuclear etc dependent?
If we are to articulate effective arguments against those who naysay bitcoin over its carbon footprint, then we must do so with good data to backup our positions.
Hopefully the numbers above are accurate/correct. Honestly only spent a few minutes doing napkin math, so I expect there to be mistakes, please let me know and thank you very much all.

Questions post! (Newbie miner) Also potential build included at bottom.

Important note: I have tried searching for most of these questions, and as for earnings, the only things I can find are people from 2014-2015 saying that GPU mining is dead, and on the other topics, it's all very vague or overly complex answers which my brain can't wrap itself around.
So hopefully this post won't be totally trampled, as I will probably ask some really stupid question. Bear in mind, I recently discovered bitcoin mining about 10 days ago. Since then I've had some good replies from a miner on another subreddit, and he assures me that GPU mining is now back in action. This is ofcourse dependent on power prices, but with my 0.04$ kW/h, I was all good.
At first I didn't wanna go all-in with this, but seeing Bitcoin rise in prices, and being personally very sure that it'll keep rising, I'm more intrigued to up the ante.
I'll also try and update this post as it goes along with "yes/no" answers, as/if they get answered.
So, here we go!
First off, I wanted to ask questions in regards to Bitcoin mining and GPU mining. Personal opinions are of course welcome.
  1. Is GPU mining still viable? I've already been told by one person that it is, but would like to hear other people's opinion.
  2. Will Bitcoin mining become harder and less profitable in the near (2-3 years) future? The reason I ask this, is because I've read that only the chinese with the best ASIC's can keep earning money today, and for them, it also becomes harder every day, and they earn less and less. Hopefully this isn't true.
  3. As the price of Bitcoin goes up (if it does), will NiceHash mining become more and more profitable?
In this next section, I wanna dive a bit more into NiceHash, and what it is exactly.
From what I've read, it basically rents out your hashing power, so you're not really mining, despite the program being called "miner".
  1. Is there something I missed there, or is that correct? Are you just renting out your hashing power?
  2. If the above is right, does NiceHash always rent out your hashing power to whatever is most profitable?
  3. What exactly is Lbry, Lyra2REv2, Pascal, Equihash etc.? Are they pools? Algorithms?
  4. Say I go to the profibility calculator, and I see that Lyra2REv2 is the most profitable for my GPU, at 39.5%. Does this then mean that I should pick only that in my NiceHash algorithm settings? Or should I pick the ones who are at 29.8% (Lbry) and 23.8% (Equihash) aswell? Does that increase my gains?
  5. If the last one above was correct, would it then be best to check the calculator daily, and only select the algorithm that earns the most based on %?
  6. Is the NiceHash profitability calculator correct, or is it just very rough estimates? Can I really earn 1220$ worth in Bitcoin over 1 year on my GTX 1080ti? (disregarding Bitcoin price changes ofcourse)
Now I'd like to delve more into my own calculations, what I have per today, and what I would like to try out. I'm very glad if you could point out some huge flaws in my plan, and crush my dreams. I would appreciate that a lot more than just letting me try it and loosing tons of capital. Obviously, if there's a question of just risking it, I'll take this decision myself. But helpful input is always welcome!
My GPU, daily profit, power cost etc.
  • GTX 1080ti FE
  • Daily profit: 5-8$
  • Power cost: 0.04$ (I live in Norway)
  • Environment: Humid, cold, lot of wind
  • Living area: Above ground "basement"
So I don't know if all of the above matters, but that's at least something to go by. From what I can understand, these are good conditions. Correct me if I'm wrong.
I was curious as to what I could earn if I built a proper dedicated rig for pure GPU mining. So I went to a popular website we use called Komplett.no and checked out some prices. Here's what I got. Bear in mind that these are all new parts with at least 2 year warranty and 5 year customer warranty.
  • Mobo: ASUS Prime Z270-P, Socket-1151 (146$)
Picked this MOBO as you could have up to 8 (?) GPU's connected to it with some nifty connectors.
  • CPU: Intel Celeron G3930 Kaby Lake (60$)
Just found whatever CPU that was cheapest.
  • RAM: Crucial DDR4 2133MHz 4GB x2 = 8gb (85$)
Cheapest I could find for the MOBO.
  • SSD: Kingston A400 120GB 2.5" SSD (70$)
Also the cheapest. Could probably find something even cheaper on our "craigslist" but I guess it's best to have a new warranty.
  • PSU: Corsair AX1200, 1200W PSU (403$)
From what I understand, AX is platinum rated, and I assume this would be best if I'm going to maybe implement more than 2 graphics cards in the future? Or would it be best to buy 2 cheaper gold ones and connect them together? And do you get significant profit increases if you go up in rating? Or is too small to even bother?
  • GPU: 980GTX x2 on our "craigslists" (475$ for both)
This is probably where I'll have the hardest time deciding. I could go for 1080's, pay more, and earn more. If this was the case, I would also be able to buy them new with a warranty on them. The decrease in value would also not be as big as with 980's. But is it worth it? I can get 1080's used for around 595$, and probably around 540$ if I haggle a little bit.
Total: 1239$ for the 980 SLI build. According to the profitability calculator, this will earn me 2440$ per year before taxes, electricity bills etc. Biggest question is then: Is this total bogus, or is it roughly correct if Bitcoin stays at the price it is today/rises?
So that's all I have up until now! I haven't seen any post this long on this subreddit yet, so if this is considered "spam" or "2much" please feel free to delete it and toss me a warning. I'm just very excited about GPU mining, and instead of posting questions every day and so forth, I'd rather just ask everything in one post :)
Thanks for reading, and have a nice day!

Trusted cloud mining services in overview

https://hashflare.io/3724EA75 (founded 2013): Contracts (One-year contracts): SHA-256: 1.5$ for 10 GH/s -> 150$ 1TH/s -> 1950$ 13TH/s (Yet 1950$ is only 1-year rental whereas your rig will stay yours forever) Fees: 0.0035 USD per every 10 GH/s (currently approx. 30% of daily earnings) ->Hashflare Profit: 3.79$-1.5$(Hardware)-1.2775$(Maintenance)=1.01$/year per 10 GH/s -> 1313$/year per 13 TH/s
SHA-256 (real S9 Miner): 2000$ 13TH/s (cf. Hashflare 1950$) Fees: 0.003$ USD per every 10 GH/s (currently approx. 25% of daily earnings) ->S9 mining rig(1400w with 0.1$ Cost pet KW/h) Profit: 3.79$-1.53$(Hardware)-1.095$(Maintenance)=1.16$/year per 10 GH/s -> 1508$/year per 13 TH/s (cf. Hashflare 1313$) But keep in mind that you can sell your hardware at any time as it stays yours forever (not 1-Year Contract) Profit w/o hardware: 3.79$-1.095$(Maintenance)=2.7$/year per 10 GH/s -> 3510$/year per 13 TH/s
*As you pay only for the hardware, you have to pay for the maintenance fees in both cases.
Conclusion: If you decide to buy your own hardware it will will stay yours forever. Nevertheless, keep in mind that you need a storage place for your mining rig and have to deal with the noise, so it should not be turned on 24/7 in your apartment.
Scrypt: 7.5$ for 1 MH/s -> 3750$ for 500 MH/s Fees: 0.01$ per every 1 MH/s (currently approx. 62% of daily earnings) ->(cf. real miner only 15%) Profit: 9.54$-7.5$(Hardware)-5$(Maintenance)=-2.96$/year per 1 MH/s -> -1480$/year per 500 MH/s)
Scrypt(real L3+ Miner): 5$ for 1 MH/s -> 2500$ for 500 MH/s Fees: 0.0038$ per every 1 MH/s (currently approx. 15% of daily earnings) ->L3+ mining rig (800w with 0.1$ Cost pet KW/h) Profit: 9.54$-5$(Hardware)-1.387$(Maintenance)=3.153$/year per 1 MH/s -> 1576$/year per 500 MH/s But keep in mind that you can sell your hardware at any time as it stays yours forever (not 1-Year Contract) Profit w/o hardware: 9.54$-1.387$(Maintenance)=8.153$/year per 1 MH/s -> 4076.5$/year per 500 MH/s
Conclusion: At this point I strongly advise not to buy any Scrypt contracts on Hashflare since you will end up losing money by doing so unless LTC suddenly skyrockets.
As other Hashflare contracts (Zero-fee contracts) are not profitable in my opinion, I will only briefly summarize the results: ETHASH: 2.2$ for 100 KH/s -> 220$ for 10 MH/s -> yields approx. 153$/year (0.51ETH), thus you will lose 67$ unless ETH goes magically up X11: 3.2$ for 1 MH/s -> 320$ for 100 MH/s -> yields approx. 60$/year (0.2 DASH), thus you will lose 260$ unless DASH goes magically up EQUIHASH: 2$ for 1 H/s -> 200$ for 100 H/s -> yields approx. 127$/year (0.54 ZEC), thus you will lose 73$ unless ZEC goes magically up
To sum it up, of course you can try your luck and hope that one of the altcoins will skyrocket to the moon and then you will make some money by joining these contracts. Nevertheless, you could also simply buy the following altcoin and make some money by simply holding the altcoin currency on an exchange. So as far as I am concerned, the only reasonable contract in Hashflare at the moment is the SHA-256 Contract.
https://www.eobot.com/new.aspx?referid=261758 (founded 2013): Eobot offers several contracts like Cloud Folding, SETI, Scrypt etc. Though they are not very profitable and thus I dont want to discuss them in detail. The only reasonable contract would be the SHA-256 5-Year Rental: 6.8$ for 10 GH/s (cf. Hashflare only 1.5$) but also keep in mind that it is a 5 Year Contract and not one year contract(cf. 1.5$*5=7.5$ for 5-Year Hashflare SHA-256).
SHA-256 5-Year Rental: 6.8$ for 10 GH/s Fees: 0.0021$ per every 10 GH/s (cf. Hashflare 0.0035$) Profit: 3.79$-(6.8$/5=1.36$)-0.77$(Maintenance)=1.66$/year per 10 GH/s -> 2158$/year per 13 TH/s (cf. Hashflare 1313$)
https://www.hashnest.com/(founded 2013): Hashnest belongs to BitMain(world's foremost producer of ASIC bitcoin mining hardware) and offers you different cloud mining possibilities. What is interesting about this site is the fact that you can buy other people´s cloud mining power vice versa (can sell it back at any time) on the Market. It is very beginner-friendly since they have the possibility to start with as little as 8000 Satoshi and buy 1 GH/s. Yet keep in mind that the withdrawal fee is 20.000 Satoshi, so you should invest at least 40.000 Satoshi in order to make some money after the withdrawal fees are deducted.
Contracts (lifetime): AntL3+: 7$ for 1 MH/s -> 3500$ for 500 MH/s (cf. L3+ mining rig discussed above) Fees: 0.0027$ USD per every 1 MH/s (currently approx. 10% of daily earnings) Profit: 9.57$-7$(Hardware)-0.98$(Maintenance)=1.59$/year per 1MH/s -> 795$/year per 500 MH/s (cf. Hashflare - 1480$) But keep in mind that you can sell your hardware at any time and it is a lifetime contract so it stays yours forever (no 1-Year Contract) Profit w/o hardware: 9.57$-0.98$(Maintenance)=8.59$/year per 1MH/s -> 4295$/year per 500 MH/s
AntS9: 3.51$ for 10 GH/s -> 351$ 1TH/s -> 4563$ 13TH/s (cf. Hashflare 1950$) Fees: 0.0019$ USD per every 10 GH/s (currently approx. 18.5% of daily earnings) Profit: 3.79$-3.51$(Hardware)-0.69$(Maintenance)=-0.4$/year per 10 GH/s -> -533$/year per 13 TH/s But keep in mind that you can sell your hardware at any time and it is a lifetime contract so it stays yours forever (no 1-Year Contract) Profit w/o hardware: 3.79$-0.69$(Maintenance)=3.1$/year per 10 GH/s -> 4300 $/year per 13 TH/s (cf.

This review should not be taken as financial advice, merely an analysis of current options. Since cryptocurrencies are highly volatile, cloud mining as well as mining in general involve certain risks e.g. difficulty increase, price drops etc. If you have any additional information or questions feel free to comment and I will try to answer as soon as possible :)

What is the best USB stick for bitcoin mining right now? How long will ASIC miners be useful?
