Bitmain Antminer S7-LN ASIC Bitcoin Miner @ 2.7TH/s with Power Supply Free Ship

Hobby Bitcoin mining can still bitmain Antminer S7-LN ASIC Bitcoin Miner @ 2.7TH/s with Power Supply Free Ship fun and even profitable if you have cheap electricity and get the best and most efficient Bitcoin mining hardware. It’s not ideal for the average person to mine since China’s cheap electricity has allowed it to dominate the mining market.

If you want bitcoins then you are better off buying bitcoins. What is an ASIC Bitcoin Miner? Since it’s now impossible to profitably mine Bitcoin with your computer, you’ll need specialized hardware called ASICs. However, Bitcoin miners discovered they could get more hashing power from graphic cards. Nowadays all serious Bitcoin mining is performed on dedicated Bitcoin mining hardware ASICs, usually in thermally-regulated data-centers with low-cost electricity. Don’t Get Confused There is Bitcoin mining hardware, which mines bitcoins. There are also Bitcoin hardware wallets like the Ledger Nano S, which secure bitcoins.

Check Profitability You can use our calculator below to check the mining hardware above. Input your expected electricity price and the hash rate of the miner for an estimate. Profitability Factors The Bitcoin price and the total network hash rate are the two main factors that will affect your profitability. Our calculator is more accurate than most others because ours assumes the 0. This has been the average daily increase over the past 6 months. Most other calculators do NOT include this metric which makes mining appear way more profitable than it actually is. The Bitcoin Price Bitcoin mining is a booming industry, but the Bitcoin price increasing can help make up some of these losses.

The Bitcoin price is increasing at an average of 0. Try messing with the calculator using different prices. Know your Competition It may seem easy to just spin up a miner. But you NEED to take a look at just how serious mining is. The video below offers an inside look at one of China’s largest mines. How many hashes per second can the Bitcoin miner make? More hashes cost more, which is why efficiency is crucial.

You’ll want to buy the most efficient bitcoin mining hardware possible. Right now, this is the Halong Mining Dragonmint T1. Since miners use a large amount of electricity, you want to buy one that converts the most amount of electricity into bitcoins. How much does the bitcoin miner cost?

Cheap mining hardware will mine less bitcoins, which is why efficiency and electricity usage are important. The fastest and more efficient mining hardware is going to cost more. Don’t try to buy a miner based on only price or only hash rate. The best ASIC miner is the most efficient bitcoin miner. Bay’s customer protection ensures you’ll get a working product.

Other bundled equipment may be included with your purchase depending on the seller. We recommend purchasing the Dragonmint or the Antminer S9. If you just want bitcoins, mining is NOT the best way to obtain coins. Buying bitcoins is the EASIEST and FASTEST way to purchase bitcoins.

Hardware Profitability You can use a bitcoin mining profitability calculator to determine your estimated cost of return on your mining hardware. Be sure to take electricity costs into account. Most mining hardware appears profitable until electricity costs are accounted for. Most Efficient Bitcoin Miners Good Bitcoin mining hardware needs to have a high hash rate.

But, efficiency is just as important. An efficient Bitcoin miner means that you pay less in electricity costs per hash. To improve your efficiency, there are also companies that will let you order hardware to their warehouse and run the miners for you. You could also cloud mine bitcoins. But both options are a lot less fun than running your hardware!

Halong Mining is the newest mining hardware company. They have the best miner available. Unfortunately, they already sold out of their first batch but a new batch should be available for sale soon. Bitmain makes the Antminer line of Bitcoin miners. Bitmain is based in China and also operates a mining pool. Its hardware is not available for purchase.

Bitcoin rigs need special power supplies to funnel and use electricity efficiently. Bitcoin hardware can easily overheat and stop working. Buy a sufficient amount of cooling fans to keep your hardware working. You may want generators as a backup in case your main source of electricity goes down. It’s still technically possible to mine bitcoins without dedicated mining hardware. However, you’ll earn less than one penny per month. Mining bitcoins on your computer will do more damage to your computer and won’t earn a profit.

So, it’s not worth it unless you’re just interested to see how the mining process works. You’re best bet is to buy dedicated hardware like the Antminer S7 or Antminer S9. USB Bitcoin miners are available to buy, but they don’t really generate any significant profits. They’re a good choice if you just want to fool around with Bitcoin mining and miners like the Antminer S9, S7, S5, Antminer R4, SP20, and Avalon6 are too expensive for you. You should buy one to learn how mining works, but other than that don’t expect much! If you are serious about making profit then check out better Bitcoin mining hardware. You can always check the profitability of a USB miner using our mining calculator.

Don’t Get Confused There is USB Bitcoin mining hardware, which mines bitcoins. There are also Bitcoin hardware wallets like the Ledger Nano S, which store bitcoins. Both are USB type devices that have completely separate functions! The Sapphire Block Erupters were the first Bitcoin USB miners.

It may be a good choice just to see how mining works, but like with most USB miners: do not expect to turn a profit. 15 per month, which is more than a dollar per year! The company claims that the device runs completely silent. It works with just one USB port.

The Avalon Nano 3 is a 3. No fan is required and it just plugs into your USB port on any computer. The plus side is it works as a wireless router, so you can do some mining while providing internet for all your devices. The 21 Bitcoin Computer isn’t the typical USB Bitcoin miner.

It does, however, plugin to your computer via USB. But since it’s still technically a USB miner we have included it in this list. If you’re not impressed, we don’t blame you! USB Bitcoin mining was only profitable when Bitcoin was in its early years.

If you just want bitcoins then invest in serious mining hardware or just buy bitcoins. Halong Mining The world of crypto was in disbelief when Halong Mining, a new ASIC startup, announced their brand new Dragonmint T16. Bitcoin mining ASIC on the market. If they delivered on their promise, Bitmain’s reign as king of ASIC developers would come to an abrupt end. Unsurprisingly, many prominent members of the Bitcoin community were in disbelief, as cryptocurrency in general has been plagued by fake startups and ICO scams. In an effort to build trust with their potential buyers, Halong Mining released videos of their ASICs running as advertised.

30 million dollars was invested in research, development, and prototypes. Their first batch of Dragonmint T16’s was set for shipment in March of 2018. As the deadline crept up, the world patiently waited for the much anticipated release. If Halong Mining really did produce the most efficient SHA-256 miner to date, the startup would prove their skeptics wrong and dethrone Bitmain, a company only concerned with their monopoly on the market. After prominent members of the Bitcoin community doubted Halong’s legitimacy, including Cøbra, the company proved them wrong. Slush, the creator of Slush Mining Pool and the TREZOR hardware wallet, claimed on Twitter the miners are legitimate. Halong Mining has earned their keep, finally viewed as a reputable company after months of speculation and debate.

The project is motivated by, and driven to help facilitate greater decentralisation in Bitcoin mining at all levels, and make SHA-256 great again. Antminer S9 The Dragonmint T16 was Halong Mining’s first ASIC to hit the market. Additionally, the T16 is remarkably power efficient, consuming a mere 0. Compared to Bitmain’s Antminer S9, which consumes 0. GH, the Dragonmint T16 is not only more powerful, but more efficient as well. The difference in power consumption seems small.

However, when mining on a large scale, every bit of saved electricity counts. What do you get when you combine power and efficiency? The T16’s new DM8575 chip design is largely responsible for the ASIC’s notable improvements over Bitmain’s S9. Although the Antminer S9 still yields a decent mining profit, it is no match for Halong Mining’s newest chip, the Dragonmint T16. Halong Mining’s Dragonmint T16 is clearly superior to Bitmain’s best ASIC miner.

ASICs’ Impact on Cryptocurrency Bitcoin is based on blockchain technology, a decentralized platform which takes power away from a central authority and gives it to the average person. Sensitive information is stored on the blockchain rather than large data centers, and is cryptographically secured. A vast amount of people, known as miners, all work together to validate the network, instead of just one person or government. In the beginning, CPUs were used to solve cryptographic hash functions, until miners discovered that GPUs were far better equipped for mining. As block difficulty increased, miners turned primarily to GPUs. Eventually, technology was developed solely for mining, known as ASICs, or Application Specific Integrated Circuits.

Their hashrates are significantly higher than anything GPUs are capable of. ASIC chips will run you a few thousand dollars each. ASICs hit the market, things changed. ASIC developers, including Bitmain, granted early access to large mining cartels rather than the average person. Nowadays, a large majority of Bitcoin mining takes place in China where electricity is cheap.

Evidently, most people can’t afford just one or two of ASICs, not to mention thousands of them. When ASICs hit the market, the blockchain’s validation process became more centralized than decentralized, as the majority of validation is done by a single mining company, rather than being spread out amongst many miners. Unfortunately, Bitcoin is no longer as decentralized as it was once intended to be. It offers a high hashrate for the amount of power it consumes. The S7 is also a popular choice among hobbyist miners for its reasonable price and strong performance. The S7 is powered by a 28nm BM1385 ASIC chip.

The strong metal casing features a tongue and groove system which allows for the neat arrangement of multiple miners. Power Supply Recommended for use with the S7 is Bitmain’s high quality 1600 Watt APW3 power supply unit, designed specifically for use with Bitcoin miners. The APW3 requires a minimum 205 Volts to function and does not ship with the necessary 16A power cord. It’s also possible to use any ATX PSU of sufficient Wattage to run the S7. As the S7-LN only draws about 700W, this PSU has excess capacity even when overclocking the unit above its default 600M frequency. It also adds quite a lot of weight to the unit, increasing its shipping cost.

While an integral PSU makes for a compact and convenient miner, there are few other reasons to recommend such a setup. The S7-LN also excludes a cord. Price Note: Before you buy an Antminer S7 make sure you already have Bitcoin mining software and a Bitcoin mining pool. 2000, a little below the current cost of the S9. These prices can be expected to fall further as the S9 and other superior mining hardware becomes the new standard. Bitcoin’s exchange rate rises sufficiently, the S7’s profitability may well be extended beyond expectations.

Using our Bitcoin mining calculator, we’ll take a peek at some likely returns for an S7 and S7-LN. For greatly increased accuracy, perform your own custom calculation! With careful tweaking, it may be possible to profit from an S7 even at 15c power. 25 Joules of power per Gigahash. Setup Both S7’s have DHCP capability, meaning they’ll automatically seek out an IP address to use.

The units will automatically begin hashing upon powering up, which can be helpful in the event of power failure. S7 connectivity is via Ethernet only. They are both cooled by dual 12038 fans. Keeping the room in which they’re placed cool and dry will extend the life of these miners. A dry basement is an ideal location.

Verdict: Is the S7 Right for You? S7 is likely your best option. With access to inexpensive power and perhaps some intelligent tweaking, it’s possible that the S7 will pay for itself and become profitable. The S7-LN is slightly more efficient and certainly better suited to the home miner who can’t tolerate a lot of fan noise or cable clutter. At that time, it was one of the fastest and most efficient ASIC miners available, rivaled by the Spondoolies-Tech SP20.

However, the S5 has long since been surpassed by newer models. As a product of a 28nm fabrication process, the S5 can’t be reasonably expected to compete with modern 16nm or 14nm ASIC designs in terms of hashrate or power efficiency. Is there still a place for the venerable S5? If you’re a hobbyist miner on a budget, with no interest in the profitability of transmogrifying electricity into bitcoins, then the S5 is worth considering. Price Note: Before you buy an Antminer S5 make sure you already have Bitcoin mining software and a Bitcoin mining pool. 413, although there may be a waiting period before stock becomes available.

Remember to factor in shipping costs and possible customs duties. Power Supply The S5 will draw between 560 to 590 Watts at around 115 Volts. Any sufficiently-powered ATX Power Supply Unit will run the S5 without problems. A list of PSU ratings may be found here. Corsair has a good reputation among Bitcoin miners and other tech enthusiasts for building reliable hardware.

The Bronze series offers good value. One thing to note is that under-clocking the S5 is difficult without a special, 9 Volt-capable PSU. Our Bitcoin mining calculator is helpful for calculating the profitability of any Bitcoin miner, based on relevant data. Be sure to run your own calculations, using your local power rate, preferred mining pool and the price at which you intend to buy your S5. Note that in July 2016, the Block Reward will halve to 12. 5 BTC for every block solved.

In order to see any bitcoins from a single S5, you will need to join a Pool. The odds of solo-mining a block with a single or even several S5s are virtually zero. Red bracketed numbers indicate negative returns. 1400, the returns would remain negative. Power Efficiency The S5 will produce 1 Gigahash for every 0. This figure can be expressed as 0.

The S5’s real power consumption, as measured by your electric bill, will vary depending on your PSU’s efficiency and the ambient temperature. There are ways, ranging from simple to extreme, to manage the overclocking burdens. This video demonstrates oil immersion cooling. Casing The S5 is open at the top and bottom and the sides are constructed of fairly lightweight plastic. This limits the placement of the unit and somewhat reduces its safety. One upside of the plastic casing is that the unit only weight 2. Noise The noise from a stock S5’s 120mm fan has been compared to an industrial vacuum.

75 decibel fan with a quieter kind. Often a secondary fan is added to the back-end, where screw holes exist for this purpose. Setup The S5 will automatically search out an available IP address to use and features an intuitive control panel. F will prolong the lifetime of the S5. As with all miners, the lower the operating temperature, the higher they can be overclocked.

Verdict The S5 is unlikely to ever turn a profit, so it’s hard to justify the cost of buying one new. That said, a cheap, second-hand S5 in decent condition is a great tool for learning the ropes of Bitcoin mining. It represents a low-cost introduction to the complex business of Bitcoin mining. The S5 is also a good platform to experiment with hardware, firmware and software tweaks and mods. Spondoolies SP20 Review Spondoolies unfortunately shut down on May 4th 2016. In late 2014, they released the SP20. We are keeping the info here for historical purposes.
