The Antminers' cases show evidence of being moved and re-setup a few times (because they have been) but all issues are cosmetic only. The biggest blemish is a rip in the plastic protective layer over one of the status LCDs on the front of the S4 units. Asking $1300 for the whole bundle, local cash at pickup or delivery within 50 miles of 60169.
In November, Venezuela’s secret police raided the house of two brothers in Caracas and found more than 90 mining terminals. The agents demanded $1,000 in bribes for each machine, according to the brothers, who spoke on the condition of anonymity because they fear arrest. The brothers said they paid the bribes to stay in business.
Authorities confiscated 300 mining terminals, according to photos published on Rico’s Instagram account, Criptonoticias reported. The models included Antminer S4s, produced by Beijing-based Bitmain, and SP31 Yukons, manufactured by Israel-based Spondoolies.
On the third one, they don't state how many miners were seized but you can presume they were a lot of them
With the arrests, authorities also seized mining machines as well as four laptops. The two bitcoin miners are awaiting prosecution at Tribunal Séptimo de Control, or the Seventh Control Court in Carabobo.
A minimum of 1470 Bitcoins has to be dumped on the market just to cover electricity cost
Unpleasant Truth... 3975 BTC are mined every day 24x60/9.06x25=3974 (24 hours x 60 minutes / ~9.06 average time between blocks x 25 BTC block reward) Assuming that the mining farms in China are using the most efficient ASIC miner available on the market, that is to say the Antminer S4, it would cost about 37%* of their mined Bitcoins just to cover the electricity cost at a rate of $0.08/kWh which is the average electricity price in China and India. So everyday, a minimum of 37% of the newly created coins has to be dumped on the market. Which is 1470.75 BTC or 423,576 USD. In an ideal world where everyone uses the most efficient ASIC miner, lives in China or India, and holds all their mined coins (and only dump as much as they need to cover the electricity), a minimum of $423,576 worth of Bitcoins has to be bought everyday on the market to maintain a stable price (no price drops). Which in fact is more likely to be double $423,576 as miners also want to make a profit (by dumping more of their BTC for $). Also, miners are located all around the world (higher electricity rates) and not everyone uses the most efficient Bitcoin miners (Bitcoin miners have to cover for the hardware cost too!). *S4specsare2TH/sfor1.38kW/hatarateof$0.08/kWh,BTCpriceat$288,difficultyat40,640,955,016.58andblockrewardof25BTC:(1.38*0.08*24)/(86400/(40640955016.58*2^32/(2*10^12))*25*288)~37%
Bitmain is a technology company specializing in high-speed, low-power custom chip design and development, successfully designed and produced a variety of ASIC custom chips and integrated systems. Bitmain was founded in 2013. In the same year, it launched the first generation bitcoin mining machine of the ant mining machine series - Antminer S1. After more than five years of development, the antminer series bitcoin mining machine passed S1, S2, S3, S4 Iterations of multiple models of S5, S7 and S9, the latest bitcoin mining models are S15 and T15, which will be sold on November 8, 2018. The Antminer S15 adopts a new 7nm chip process. The official evaluation of the S15 is durable, energy saving. Emphasizing the characteristics of "high performance, more durable, and more power saving". From the officially announced parameters, the Antminer S15 is built in. Standard and low-power mining modes. The officially announced parameters have a unit-to-power ratio of 57J/T in standard mode, and the unit-to-power ratio of low-power mode has reached 50J/T. Compared to the products in the current market, in terms of Bitcoin miners, this unit power consumption ratio has set a new record. Antminer S15 official parameters, https://preview.redd.it/9fgwfaqp6bd21.jpg?width=1015&format=pjpg&auto=webp&s=8239da7bcece1abb80f1fb56708e02fa111a150b Recently, the Antminer S15 has sent to Cybtc for testing. Please see the third-party independent review by us. I. Unpacking: Because the Antminer S15 adopts a new all-in-one and parallel fan design, the packaging box has changed from the previous generations. The previous cuboid has changed into a square-like style. The packaging material is still packaged in an industrial carton, and the box is marked manufacturer information, logistics warehousing logo, mining machine specification model and strip identification code, outer box size: 486*388*265, weight about 8.7kg. The interior of the two pieces of styrofoam is firmly packed in the box from the upper and lower sides to ensure the safety of the mining machine during transportation. There is also a gap around the pearl foam for easy access. Take out the styrofoam on one side to see the main body of the mining machine. The mining machine is wrapped by an anti-electrostatic bag. Compared with the box, the mining machine looks very small and only takes up about half of the box space. The Antminer S15 changed the style of single-tube with double cooling fans as S1-S9 models, and became a dual-fan parallel single-side air intake and adopted the integrated machine design of the mining machine + power supply. The whole machine size is 279*175*221mm, weight 7.13 kg. https://preview.redd.it/k0xp89yy6bd21.jpg?width=640&format=pjpg&auto=webp&s=5504d958a4cc6fdb1c01783b777e60483ea7ef9a The Antminer S15 is small and neat, the air inlet side and the mining machine interface side are on the same side, the fan is removed from the air outlet side, and a honeycomb-shaped baffle is used. https://preview.redd.it/ex187jf27bd21.jpg?width=640&format=pjpg&auto=webp&s=e8210c514e186dae075d9b986f7682a49141aa6a The advantage of the all-in-one design is that the wire connection is reduced. The appearance of the mining machine is more compact, and the use and operation and maintenance are more convenient. The connection between the Antminer S15 mining machine and the power supply uses a clip-connected design, and the controller and the power board are still connected by flat signal cable. https://preview.redd.it/85cz4u4c7bd21.jpg?width=640&format=pjpg&auto=webp&s=ab87c2f4c2943f0e9eb3dbbe2576f9d043add399 The nameplate of the mining machine body is marked with the model number, hash rate, and identification bar code. If the bottom part can increase the anti-slip mat, it is better to strengthen the stability of the mining machine when it is placed horizontally. The mining machine supports the erect and horizontal two ways. On the rack, the miner can choose the placement method according to the size of the mine rack. https://preview.redd.it/wxavyize7bd21.jpg?width=640&format=pjpg&auto=webp&s=5ab2335eabb3b13731284f89805abcb131bfbda4 II. Antminer S15 installation: The design of the Antminer S15 all-in-one machine reduces the link of the power line of the plugging and unloading machine. As long as it is placed in the rack, plug in the power cable and the network cable to complete the hardware installation. Find the mine IP address. Antminer S15 mining machine is automatically assigned IP mode, you can enter the local router to view the IP address named "antMiner". Or use the ant official mining machine management software BitmainMinerTool to scan the IP address of the current mining machine. You can also use the management software to set the mining pool address and worker name, update the firmware, etc. When the number of mining machines is large, you can also use the mining machine. IP report button to find the IP address of the mining machine. To view the real-time status of a single mining machine, you need to enter the mining machine control page. First, enter the mining machine IP into the control page home page, and then enter the default user name and password (the default is root) to enter the mining machine control page. The new mining machine needs to modify the name of the mining pool and miners, click on the “Miner Configuration” page to modify the main mining pool address and worker name, and modify the two alternate mining pool addresses and miners' names as needed. Antminer S15 has built-in standard and low-power mining modes, so you can easily select any mode mining on this page according to your needs. After each setting is completed, click “Save&Apply” to save the settings and apply. After saving, the miner will restart the mining procedure. After about a few minutes of normal operation of the mining machine, you can enter the mining operation interface “Miner Status” to check the operation of the mining machine, including running time, hash rate, Chip status, operating frequency, PCB board and chip temperature, fan speed and other parameters information. III. Review: The Antminer S15 has standard mining mode and low power consumption mode. Therefore, we tested the two modes for 24 hours respectively. The test environment temperature is about 17 degrees, and the noise value is around 36 decibels. https://preview.redd.it/2wzornwmabd21.jpg?width=640&format=pjpg&auto=webp&s=62e6e57755d70d526eeda4066a31b042473871a8 After the mining machine is turned on, the fan runs at full speed, the power consumption of the boot is about 25W and further increases slowly, and the noise level is up to 81.2 dB. Standard mode test Power consumption: The miner's chip is fully operational, and the control page power is 28T. The measured power consumption of the miner is 1610-1620W, which is in line with the officially announced 1596W ±7% level. Noise: Due to the low ambient temperature, the number of fan rotations is basically stable at around 3120 rpm. The noise value of the operating environment is measured to be 76.5 decibels. The distance of the mine is 27.7 meters, and the noise level is properly controlled. Temperature: Antminer S15 has a total of four mining boards. There are four temperature-sensing modules distributed on each calculation board. The chip temperature is at least 44 degrees and the highest is 78 degrees. Thanks to the Exposed Die package, the outlet temperature is about 42 degrees. The power outlet temperature is about 28 degrees. https://preview.redd.it/h71plzf0bbd21.jpg?width=641&format=pjpg&auto=webp&s=588728e6a87b510d5cc65eb41a1ffe80d6435f17 Because the Antminer S15 adopts the one-piece design, We also test the contact temperature of the power supply and the mining machine's power board. It can be clearly seen that the temperature values of each point are different. https://preview.redd.it/4ghcl4i3bbd21.jpg?width=990&format=pjpg&auto=webp&s=a344917e4a3b529aef58127f5e5c8fdaa61c62fa Hash rate: After 24 hours test in the btc.com mining pool, the average hash rate of the Antminer S15 in 24 hours was 28.56 TH/s. Thus calculate the unit energy efficiency ratio = 1620W / 28.56 ≈ 56.72W / T, and the official published data 57 J / T consistent. Low power mode test Power consumption: After checking the option behind “Low Power Mode” on the Antminer S15 Pool Settings page and saving the application, the miner can run in low power mode. After the power of the mining machine control page reaches 17T, the measured power consumption is up to 836.6W, and the running data meets the official data of 775W ±7% - 900W ±7%. Noise: As the power and power consumption are reduced, the fan speed is basically stable at around 2400 rpm, the measured operating environment noise value is 77 decibels, and the distance measured by the mining machine is about 66 decibels at a distance of 2 meters. The noise level and the standard mode. At the same level. Temperature: The four mining board chips have a minimum temperature of 25 degrees and a maximum of 62 degrees. The outlet temperature is about 30 degrees, which is slightly lower than the standard mode. The temperature of the power outlet is about 20 degrees. https://preview.redd.it/r4f2ww96cbd21.jpg?width=641&format=pjpg&auto=webp&s=ae3051c74634ac9d98373d71e8fee3f542d455c5 Contact point temperature value between the power supply and mining machine mining board. https://preview.redd.it/fskmubi8cbd21.jpg?width=990&format=pjpg&auto=webp&s=a1616d21af2b87bc0996f1ce388b3ab9983d33dd Hash rate: After 24 hours of testing in the btc.com mine, the average 24-hour power was measured at 17.5TH/S. Thus calculate the unit energy efficiency ratio = 836.6W / 17.5 ≈ 47.8W / T, lower than the official published data 50 J / T. IV. Summary: Two built-in mining modes. The power consumption per unit of power in low-power mode is lower than 50W/T, which is better. The lower the power consumption ratio, the lower the price of the shutdown. One machine design reduces the wire, beautiful and convenient. Exposed Die package improves heat dissipation, increasing the number of chips per unit volume and reducing heat sinks, reducing overall weight. The new AWP8 power supply is used, easy to assemble and disassemble. The machine noise is lower and the temperature is lower than other mining machines. The calculation power of the whole machine is stable and fluctuating. Finally, exposed power connectors may cause problems if touch the iron on the shelf. Maybe it can have improvement. The Antminer series mining machine has evolved from S1 to S15, and the computing power has evolved from S180's 180G/360W to S15's 28000G/1600W. This is not just a digital evolution, but also the ups and downs of the Bitcoin industry. The mining machine is upgrading. Bitcoin is advancing, leaving many stories in the chain, the currency circle and the mining ring than the ten-year journey of holding the currency. In the two-year life cycle of S9, S9's bitcoin mining machine market share is far ahead, and currently in the market background of the rising bitcoin computing power, the depressed bear market and more new mining machines, Whether the ant S15 can create a new benchmark for the bitcoin mining machine, time will give us the answer.

At what price will Bitcoin fail to function? My estimate: ~$100.
I'll begin with my conclusions: If the Bitcoin network consisted solely of 'Titanium ASIC' miners, the most powerful and energy efficient mining machine I know of, then the price point at which electricity costs begins to exceed rewards is $71/BTC (based on yesterday's network figures; more on that later). More realistically though, most miners aren't running highly efficient Titanium ASICs, hence I estimate ~$100/BTC as the turning point. I say 'fail to function' in my title, because who will continue to mine at a pure loss? It would be irrational - the rational action would be turn off the machine until the value of the rewards increases. Note: This is not the same as sunk costs in buying hardware - because in that case even if you never get back how much you paid, you're still making something. Perhaps, you might counter, Bitcoin enthusiasts will continue to mine at a loss. Well consider this: To sustain just 1% of the current network hash rate, you would require 559 Titanium ASICs costing over one million dollars in yearly electricity cost (at $0.10/kWh) - and that's a best case scenario. Let's assume that's the case - you have Bitcoin Enthusiasts contributing the equivalent of 559 Titanium ASICs hashing power for free out of their pocket. That's a 99% drop in hash rate. The time to a difficulty retarget is 2016 blocks, or at 10minutes/block that's 2 weeks. But if the hash rate were to drop by 99% within that two week period, then the block time would balloon out to 16.66 hours - making the block retarget ETA up to 3.8 years! If transactions took 16.66 hours just to get a single confirmation (if they had first priority), then how would use of Bitcoin remain practically feasible? Would people still have confidence in the system and the developers for allowing this to happen? How difficult or costly would it be to launch a 51% attack? Now, on to the calculations, and a few less optimistic alternate scenarios: Network hash rate at time of calculation: 335,365,290.09 GH/s 335,365,290.09 GH/s / 6000GH/s = 55894.215 'Titanium ASIC' miners 55894.215 x $5.28 daily electricity cost (At $0.10/kWh) = $295121.4552/day in electricity costs = $1776.87709485/block (avg. time of 8.67 minutes) $1776.87709485 / 25BTC block reward = $71.04/BTC = break even point. The above does not account for pool fees or transaction fee revenue or more importantly variance in kWh rates ($0.10/kWh is nonetheless pretty low worldwide), and hardware cost is irrelevant to this calculation. Without doing all the math again, here's some other popular mining machines for comparison: $113.07 (SP35 Yukon) $193.84 (CoinTerra TerraMiner IV) $385.89 (Antminer S1) I've also just seen the 'Antminer S4' mentioned in /Bitcoin, so just for comparison a Titanium ASIC is almost twice as energy efficient as an Antiminer S4 (2200W vs. 4200W for 6TH/s) - it's less efficient than the SP35 Yukon. If I've made any miscalculations here or have left anything important out, feel free to correct me.
Been mining for about 2 years now and I've been using the S5 since its release with positive results. Even with free electricity the difficulty increase is grinding my payouts to a halt and I've been considering another miner but nothing seems to have the hash power to offset the difficulty for long. Currently the S4 looks good as I've seen prices as low as $495. Is anyone considering buying any new hardware or is the consensus buying bitcoin outright now that the difficulty is so high? Thanks for any insight!
I have 2 1/2 Antminer s3s "think a board is burnt on one" and an Antminer s4+. In the good times I was mining nearly 1btc a month. I moved and never hooked back up the miners. My electric rate is about 10 cents a kw/h. The calculators say I will be slightly losing by running them. With bitcoin on the rise do y'all think it is worth it to fire them back up? I live in the suburbs of New Orleans so heating my house would not be beneficial right now. I could always put them in my shed though.
Overview - Table of Contents Introduction to Earning in Bitcoin Work for Bitcoin Sell for Bitcoin Affiliate Programs Gambling Bitcoin Mining Hardware Mining Cloud Mining Introduction to Earning in Bitcoin Bitcoin is the most popular digital currency in the world today. Bitcoin cloud mining is the fastest way to immediately begin earning bitcoins. Bitcoin is built using very complicated cryptographic principles, and supported by countless individuals and companies from all around the world. By early 2016, total Bitcoin market capitalization had crossed USD 7 Billion, making it almost as valuable as the GDP of a small country like Bahamas. All the other digital currencies together do not constitute even 20% of Bitcoin’s market capitalization, underlining the its dominance and importance in the world of digital currencies. With such a huge amount of world’s capital available in the form of Bitcoins, the number and types of opportunities to earn in bitcoins are increasing by the day. In this article we will discuss such opportunities that help us earn bitcoins. We will start with the easiest, or the one that is applicable for the maximum number of people, and then move to the tougher ones. In the end we will cover earning bitcoins by mining. Bitcoin mining is not an easy way to earn bitcoins, but we do have a number of easier ones we will discuss first. So lets start with ‘earning bitcoins by offering your services’ Work for Bitcoin Perhaps the easiest way to earn bitcoins is to work online or in real life for bitcoins. Because of the huge size of the bitcoin eco-system, a number of such opportunities and jobs are available. With Billions of dollars invested in Bitcoin by tens of thousands of people, there is a real market in Bitcoin, where you can find jobs for freelancers, software developers, writers, and others who get paid in bitcoins for their services. Software development, writing, design, making websites or apps, audio transcription, are some of the most active types of jobs. You can easily discover the types of jobs by going over the more popular job boards for bitcoin related work. The following job boards or forums are some of the best places to look for such jobs or gigs. Freelancing XBTfreelancer Cryptogrind Bitlancerr Coinality Bitgigs Jobs4Bitcoins Rein Project Crypto Jobs List Market Places OpenBazaar Purse.io Bitify /bitmarket 21 Market Video Streaming Watchmybit Streamium.io Tasks Bitasker BitforTip WillPayCoin File/Image Sharing Supload.com SatoshiBox JoyStream Advertising CoinAd A-ads Coinzilla.io Also, check BitcoinGames for ideas on earning bitcoin and blockchain game assets. Sell for bitcoin You can also get Bitcoin by selling your old laptops, phones or other items for Bitcoins. Such types of transactions are happening more and more, and a lot of buyers are already buying anything from iPhones to even cars by paying with Bitcoins. For Americans, Craigslist.com is your best bet when you want to find such buyers. You can mention in your ad that you are willing to take payment in Bitcoin. This way if anyone wants to buy the item for you for Bitcoin, they can contact you and make an offer. The same principle applies to other online marketplaces such as gumtree for UK, kijiji for canda etc. Affiliate Programs Affiliate programs allow a promoter of a business or product to earn money or bitcoins by refering new clients to such businesses or products. For example, amazon.com has a popular affiliate program, where you can earn commission ranging from 2% to 20% for refering clients to products listed on amazon.com. Amazon normally pays in dollars, but there are a number of other sites and businesses which pay you in bitcoin for acting as their affiliate. Some of the more popular affiliate programs that pay out in Bitcoin are by the sites: cex.io, coinbase.com, okcoin.com and namecheap.com, among others. You can find a larger list of such affiliate programs on the bitcoin wiki page for Affiliates. Gambling We do not recommend gambling for every player or every user; we find that gambling is only suitable for people who know how to win at it. However, if you are one of such lucky users who have some tricks up their sleeves, and can manage to win at games such as poker, then you will find that earning bitcoins is not that hard. One of the many applications of bitcoin since the very beginning have been in betting games or gambling. Because of the relative anonymity of bitcoin, and the lower fees, it is very suitable for gambling related applications. Indeed, one such game, satoshiDICE, has been running since 2012, and has paid out a huge number of bitcoins in innumerable transactions to its winners. There are many such games, which you can find be googling. If you want to gamble totally anonymously, you can play gambling or betting games that are available only on darknet or .onion sites. Such sites allow you to browse them anonymous by operating on the tor network, which is a secure network that allows users to browse .onion websites without exposing their own IP address. Bitcoin Mining For each block that is added to the Bitcoin Blockchain, a number of bitcoins are rewarded to the creater of that block. This reward is currently, as of June 2016, 25 bitcoins per block, and it halves every four years. The next halving will be in July 2016. Creating or finding the new blocks, and therefore winning the reward of 25 bitcoins for each block you create, is called bitcoin mining. To do bitcoin mining successfully, you need very powerful computers, which compete with other computers to find the next block. The speed or power of computer that do bitcoin mining is calculated in hashes calculated per second. There are two ways to do bitcoin mining: one is to own hardware or computers that do the mining, and second is to hire the hardware from a third party, usually online, and do the mining on the cloud. Let us discuss the advantages and disadvantages of both in next two sections. Hardware Mining When you own the hardware that does the calculations and mining of bitcoins, its called hardware mining. Hardware mining is the more popular or prevalent of the two types of mining we mentioned. One of the biggest factors which comes into play when doing bitcoin mining using your own hardware is the price of electricity. If you pay top price for electricity, then bitcoin mining may not be your cup of tea. Another related factor is infrastructure needed to cool the hardware; since every cpu generates some amount of heat, you may need to cool the hardware in case they become too heated. No wonder that some of the most successful miners work from China, specially Tibet, where they can get cheap electricity, and their cooling costs are low due to high altitude which reduces the ambient temperature for them. For a more in-depth information on how to setup your hardware mining equipment, have a look at the Antminer setup page. Currently, based on (1) price per hash and (2) electrical efficiency the best Bitcoin miner options are: AntMiner S7 AntMiner S7 Bitcoin Miner 4.73 Th/s 0.25 W/Gh 8.8 pounds Yes $479.95 AntMiner S7 Bitcoin Miner 0.1645 AntMiner S9 AntMiner S9 Bitcoin Miner 13.5 Th/s 0.098 W/Gh 8.1 pounds Yes $1,987.95 AntMiner S9 Bitcoin Miner 0.3603 Avalon6 Avalon6 Bitcoin Miner 3.5 Th/s 0.29 W/Gh 9.5 pounds No $499.95 Avalon6 Bitcoin Miner 0.1232 Cloud Mining There are a number of service providers that allow you to rent computational hardware from them, which can then be used to do bitcon mining. Some of these services are designed with bitcoin mining in mind, whereas others such as Amazon AWS are general purpose services that can also be used to do bitcoin mining. Some of the cloud mining services which can be used to do bitcoin mining on the cloud are: Hashflare Review: Hashflare offers SHA-256 mining contracts and more profitable SHA-256 coins can be mined while automatic payouts are still in BTC. Customers must purchase at least 10 GH/s. Genesis Mining Review: Genesis Mining is the largest Bitcoin and scrypt cloud mining provider.
