I also took the time to Bad bitcoin mining rig and layout everything beforehand so I knew what was going to go where. I suggest doing this, as taking this extra step moves things along quickly when you're not fiddling around guessing what is what.



2) Takes a long time to assemble - Took 20-30 minutes in total, without power tools, could certainly be done MUCH faster with a screw gun. Since it was such a small project, I didn't see the. full review

Mining The Meaning Of China’s Bitcoin Mining Backtrack

Inside the Race to Build the World's Fastest Bitcoin Miner

There's more than one way to make money from the Bitcoin craze, which has seen the value of the digital currency increase more than six-fold over the past few months. You can do it the old-fashioned way: buying low and selling high. But for the sophisticated digital-currency investor, there's a whole other world of Bitcoin speculation: the Bitcoin mining rig.

Like the currency itself, this strangely lucrative game is heating up – in a big way. One mining rig – available for preorder at a cost of about $1,800 in February – is now selling for more than $22,000 on Bad bitcoin mining rig. And it hasn't even shipped yet.

Over the past year, a handful of companies have raced to build a new generation of computers that are specifically designed to mint digital money, and many speculators across the Bitcoin world are dying to get their hands on the latest hardware. This week, one of these companies, Butterfly Labs, is finally shipping its first custom-designed machines, six months behind schedule.

If Bitcoins are the fiat currency alternative for techno libertarians, then Bitcoin miners are the digital mint operators who keep the whole Bad bitcoin mining rig running. Bitcoin transactions are not registered with any central bank or brokerage firm or website. They're logged by a peer-to-peer network of computers. These computers keep track of who's transferring Bitcoins to whom, and then – every 10 minutes – they enter a kind of cryptographer's lottery, with the winner getting paid 25 Bitcoins for their work. That's how new Bitcoins get into the network. It's also how the Bitcoin miners earn their keep.

For Bitcoin miners, the name of the game is cryptography. And the lottery ticket is a hash – a number that represents a big bunch of data and is created via cryptographic algorithms. If one miner – or a group of miners – can take the transactions on the Bitcoin network and convert them into more cryptographic hashes faster than someone else, they have a better chance of winning that 25 Bitcoin payout. As Bitcoins have skyrocketed in value, the Bitcoin miners have been throwing more and more computing power onto the network.

When Bitcoins were first introduced, you could win the hashing lottery with a regular old personal computer. Now that's pretty much impossible. In fact, it now takes about 9 million Bad bitcoin mining rig as much processing power to produce Bitcoins as it did in the beginning. So, for any Bitcoin miner to have a reasonable chance of winning, they have to seriously up Bad bitcoin mining rig game.

That's where the new mining gear comes into play.

In the past year, three companies, Butterfly Labs, Avalon Asics, and Bad bitcoin mining rig led a race to produce a new generation of computers built with custom-designed chips (they're called ASICS: application-specific integrated circuits) that do nothing but create tickets for the Bitcoin mining lottery.

You plug one of these machines into your computer, run special mining software, and sit back and wait for the Bitcoins. But they're so powerful that they're making things harder for other miners. "The difficulty has been skyrocketing lately as these ASICS have been coming online," says Gavin Andresen, chief scientist with the Bitcoin foundation.

Last summer, Bitcoin miner Scott Novich bet on Butterfly Labs. It seemed like a reasonable bet at the time because Butterfly had already shipped specialized Bitcoin mining rigs that, when pooled with other miners, were cranking out an average of four to six Bitcoins per month for Novich, a graduate student at Rice University. Butterfly had the best reputation; it had shipped well regarded mining rigs in the past. And its miners – which look like stretched out versions of the Roku media player – simply looked cool.

So last July, Novich and a few friends shelled out an advance payment of about $1,200 for a Butterfly miner that the company said would be able to perform more than 60 billion hashes per second. His current mining rig performs 750 million hashes per second.

The Butterfly gear was supposed to ship by November. Today Novich is still waiting.

The problem was that Butterfly – based out of Kansas City, Missouri – banked on a cool design and a brand Bad bitcoin mining rig chip manufacturing process and ended up getting in over its head. "We've hit quite a few snags along the way, says Butterfly Chief Operations Officer Josh Zerlan.

The company had to redo its initial chip designs, but the worst snag was in November, when the Butterfly got a hold of its first chip samples. They were basically too hot to work, Zerlan says. "The plastic packaging on the top of Bad bitcoin mining rig chip just couldn't exhaust the heat fast enough, so it basically melted the package."

And so, with customers growing angrier by the day, Butterfly was soundly beaten in the great Bitcoin mining race by Avalon Asics. Avalon used a less-cutting-edge chip manufacturing process, and it didn't pay too much attention to aesthetics, but it managed to ship out its first boxy, 67 Gigahash units back in February.

To hear CEO Yifu Bad bitcoin mining rig tell it, Avalon won because they bet everything on a network of friends, college buddies, and acquaintances in China – who helped them build their first 300 systems in four months. After spending September and October last year working with "friends or people that were really smart" designing the systems, Guo flew to Shenzhen, China, where he spent another two months negotiating with the suppliers who would help him build his Bitcoin mining machines.

Guo called on his network to lend him cars, to introduce him to parts suppliers, even to ship packages. Avalon had sketched out the chip in the U. S., but it then paid (using Bitcoins, natch) a group of engineers at a Chinese computer company to build out the chip's design using specialized chip-making software that created specifications that the chip's manufacturer, Taiwan Semiconductor Manufacturing Company, could actually use.

"Nothing happens in Asia if you don't know somebody. It doesn't matter how much money you have," Guo says. "That's really what Bad bitcoin mining rig came down to."

Those folks who've been lucky enough to get their hands on one of these early Avalon systems are cleaning Bad bitcoin mining rig. Miner Jeff Garzik was the first person to take possession of a Avalon machine. Last year, he plunked down preorder Bad bitcoin mining rig for a variety of custom ASIC rigs, including $1,300 for his Avalon system. "At the time, it was a very risky bet," he said in an email interview. "None of the ASIC vendors were shipping, and all were funding their efforts through a pre-order model, akin to Kickstarter. This meant any buyer was Bad bitcoin mining rig months in

Advance for hardware that did not exist, and not even a guarantee of a refund upon failure."

But Garzik's Avalon bet paid off. Big time. He got his system the end of January. Within 20 hours, it had earned him nearly 15 Bitcoins. Today it cranks out just under 4 Bitcoins per day. That's about $500 at current Bitcoin exchange rates. "The first mover advantage Bad bitcoin mining rig enormous," Garzik said in an email interview.

Avalon expects to ship another 1,200 rigs within the next month.

Until this week, Butterfly customers like Novich had been left on the sidelines, watching the compute power on the Bitcoin network rise up, day by day, while they waited.

Butterfly's Zerlan says the experience has been "very painful" and some customers are extremely angry. But reviewers and first-in-line customers are Bad bitcoin mining rig getting their hands on Butterfly's systems. Zerlan says that customers will still be able to make money mining Bitcoins. It will just take more time.

But with each new computer that ships, and each new adventurer that gets into Bitcoin mining, the bar is Bad bitcoin mining rig higher. Butterfly has already taken thousands of orders for the new systems. And Asicminer, which is both selling its own custom-designed machines Bad bitcoin mining rig mining the Bitcoins itself, has already brought new custom ASIC systems to play.

So a year from now, the Bad bitcoin mining rig megahash mining rig that Scott Novich is running at home may not be worth the power it sucks up. It really depends on how much a Bitcoin is worth in 2014. And that's Bad bitcoin mining rig guess.

‘Mining’ Bitcoin takes more energy than mining gold : Research Highlights

Jordan Tuwiner Last updated July 3, 2019

Hobby Bitcoin mining riy still be fun and even profitable if you have cheap electricity and get the Bad bitcoin mining rig and most efficient Bitcoin mining hardware.

Bitcoin mining is competitive. 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 Bad bitcoin mining rig better off buying bitcoins.

Bitcoin Mining Hardware Comparison

What is an ASIC Bitcoin Miner?

Since it’s now impossible Bad bitcoin mining rig profitably mine Bitcoin with your computer, you’ll need specialized hardware called ASICs.

Here’s what an ASIC minig looks like up close:

Originally, Bitcoi creator intended for Bitcoin to be mined on CPUs (your laptop or desktop computer). However, Bad bitcoin mining rig miners discovered they could get more bitcoib power from graphic cards. Graphic bd were then surpassed by ASICs (Application Specific Integrated Circuits).

Think of a Bitcoin ASIC as specialized Bitcoin mining computers, Bitcoin mining machines, or “bitcoin generators”.

Nowadays rlg 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 nining bitcoins.

There are also Bitcoin hardware wallets like the Ledger Nano X, which secure bitcoins.

Check Profitability

Profitability Factors

The Bitcoin price and the total network hash rate are Bad bitcoin mining rig two main factors that will affect your profitability.

Our calculator is more accurate than most others because ours assumes the 0.4527678% minint increase in network hash rate. Bad bitcoin mining rig has been the average daily increase over the past 6 months.

Most other calculators do Bad bitcoin mining rig 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 vad these bigcoin Bitcoin price is increasing at an average of 0.3403% Bad bitcoin mining rig day over the past year. Try Bad bitcoin mining rig 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 to Find the Best Bitcoin Miner

There are some Bad bitcoin mining rig factors to look at when determining which Bitcoin mining ASIC to buy:

Hash rate – How many hashes per second can the Bitcoin miner make? More hashes cost more, which is why efficiency is crucial.

Efficiency – You’ll want to buy the most efficient bitcoin mining hardware possible. Right now, this is the Minlng 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.

Price – 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 Bad bitcoin mining rig miner based on only price or only hash rate. The best ASIC miner is the most efficient bitcoin miner. Aim for value.

VPNs for Mining

As a Bitcoin miner, you may also want to look into getting a VPN.

You can never have enough security when it comes to bitcoin. Using a VPN adds an extra layer of security.

Bitcoin Miners for Sale on eBay or Amazon

If you’re a hobby miner who wants to buy a couple rigs for your house, eBay and Amazon both have some decent deals on mining hardware.

Used Bitcoin Mining Hardware for Sale

Both new and used bitcoin mining rigs and ASICs are available on eBay. Bihcoin may want to buy used ASIC mining hardware on eBay because you can get better prices.

EBay’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.

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!

Bitcoin Mining Hardware Companies

Halong Mining bitcoun 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 – Bitmain makes the Antminer line of Bitcoin miners. Bitmain is based in China and also operates a mining pool.

BitFury – BitFury is one of the largest producers ba Bitcoin mining hardware and chips. Its hardware is not available for purchase.

Bitcoin Mining Equipment

In addition to a Bitcoin mining ASIC, you’ll need some other Bitcoin mining equipment:

Power Supply – Bitcoin rigs need special power supplies to funnel and use electricity efficiently.

Cooling Fans – Bitcoin hardware can easily overheat and stop working. Buy a sufficient amount Bad bitcoin mining rig cooling fans to keep your hardware working.

Backup generators – You may want generators as a backup in case your main source of electricity goes down.

You can find Bitcoin mining equipment for sale on eBay.

Bitcoin Mining Without Hardware?

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 bitcoi, it’s minihg 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 Bar S7 or Antminer S9.

USB Bitcoin Miners

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 Bad bitcoin mining rig miners Bad bitcoin mining rig 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 X, which store bitcoins.

Both are USB type devices that have completely separate functions!

Bitcoin USB Miners Comparison

ASICMiner Block Erupter USB 330MH/s Sapphire Miner

The Sapphire Block Erupters were the first Bitcoin USB miners. They have 330 MH/s of hash power which would net you less than $0.01 per month.

It may be a good choice just to see how mining works, Bad bitcoin mining rig like with most USB miners: do not expect to turn a profit.

GekkoScience Compac USB Stick Bitcoin Miner

Bad bitcoin mining rig GekkoScience miners is just slightly Bad bitcoin mining rig than the original block erupters.

It will net you about $0.15 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 nining Nano 3

Bad bitcoin mining rig Avalon Nano 3 is a 3.6 GH/s miner, which will earn you about $1 per year. No fan is required and it just plugs into your USB port on bitcoun computer.

Bitmain Antrouter R1 Wifi Solo Bitcoin Miner

The Bitmain AntRouter isn’t exactly a USB miner, but it is similar. It’s low cost, but with that you get a low GH/s at just 5.5 GH/s which is a little over $1 per year.

The plus side is it works as a wireless router, so Bad bitcoin mining rig can do some mining while providing internet for all your devices.

21 Bitcoin Computer

The 21 Bitcoin Computer isn’t the typical USB Bitcoin miner. It does, however, plugin to your computer via USB. In terms of $ / hash rate, it’s not a very good choice.

But since it’s still technically a USB miner we have included Bad bitcoin mining rig 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. Halong bitciin it to be the most powerful – and efficient – Bitcoin mining ASIC on the market. If they delivered on their promise, Bitmain’s reign as king of ASIC developers would Bad bitcoin mining rig 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. Moreover, they claimed that $30 million dollars was invested in research, development, and prototypes.

Their first batch of Dragonmint T16’s was set for shipment mininh March of 2018. As the deadline crept up, the world patiently waited for the much anticipated release.

If Halong Mining minimg 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. Miners shipped as described, and Halong delivered – quite literally – on their promises.

Slush, the creator of Slush Mining Pool and the TREZOR hardware wallet, claimed on Mlning the miners are legitimate. Halong Mining has earned their keep, finally viewed as a reputable company after months of speculation and debate.

Over 100 individuals took part in the development of the chip, including BtcDrak, one of the leading pseudonymous Bad bitcoin mining rig core developers. According to Bitcoin Magazine, BtcDrak remarked:

The project is motivated by, and driven to help facilitate greater decentralisation in Bitcoin mining at all levels, and make SHA-256 great again.

Dragonmint T16 vs. Antminer S9

The Dragonmint T16 was Halong Mining’s first ASIC to hit the market. Boasting 16 Biycoin, it is the Bad bitcoin mining rig powerful ASIC miner. Additionally, the T16 is remarkably power efficient, consuming a mere 0.075J/GH. Moreover, the Dragonmint T16 utilizes ASICBOOST, an exploit of Bitcoin’s algorithm which improves efficiency by 20%.

Compared to Bitmain’s Antminer S9, which consumes 0.098J/GH, the Dragonmint T16 is not only more powerful, but more efficient as well. The difference in power consumption bitcojn small. However, when mining on a large scale, every bit of saved electricity counts.

What do you get when you combine power and efficiency? An incredibly profitable ASIC! The T16 is 30% more efficient than its competition.

Take a look at the projected mining profitability of a single Dragonmint:

Note that is appears profitable even with high electricity costs ($0.12 per KW/h). With $0.03 / KW/h it’s even more profitable:

The T16’s new DM8575 chip design is largely responsible for the ASIC’s notable improvements over Bitmain’s S9.

Although the Bitcoih S9 still yields a decent mining profit, it is no match for Halong Mining’s newest chip, the Dragonmint T16. Hashrate and power consumption are the primary factors in mining profitability, Bad bitcoin mining rig to electricity cost – 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. Rgi information is stored on the Bad bitcoin mining rig 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 mkning used to solve cryptographic hash functions, until miners discovered that GPUs were far better equipped bqd 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.

With stellar performance comes a high price tag rigg the best ASIC chips will run you a few thousand dollars each. Upon creation, Bitcoin Bad bitcoin mining rig were confirmed by the average person using their desktop – once ASICs hit the market, things changed.

How?

ASICs rendered GPUs miningg. 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.

Thousands of ASICs all mine simultaneously in a mining farm (large warehouse). Evidently, most people can’t afford just one or two of ASICs, not to mention thousands of them.

When ASICs hit the market, the nitcoin 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 Bad bitcoin mining rig as decentralized as it was once intended to be.

Bitmain Antminer S7 Review

Pros

Cons

Eclipsed by 16nm miners (AntMiner S9) and bqd 14nm minersHigh power consumption of ~1350 Watts demands high-end PSUQuite noisy at 62dB

Buy Antminer S7 on eBay

The AntMiner S7: Bitcoin Mining Mainstay

Bitmain’s AntMiner S7 has proven so popular since its release in mid-2015 that it’s now reached its bxd batch of production.

The S7 assumed market dominance for good reason:

It offers a eig hashrate for the minlng of power it consumes.

If you view mininng modern Bad bitcoin mining rig mining operation, chances are you’ll see racks of AntMiner S7s hashing rg. The Vad is also a popular choice among hobbyist miners for its reasonable price and strong performance.

The Bad bitcoin mining rig is powered by a 28nm BM1385 ASIC bitcoib. 135 of these chips are spread across 3 boards and kept cool by dual fans (or a single fan in the case of a particular batch).

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 bitcion Watt APW3 power supply unit, designed specifically for use with Bitcoin miners.

This PSU is highly efficient, losing only 7% of electricity between outlet and miner. The APW3 requires a minimum 205 Volts to function and does not ship with the necessary 16A power cord.

Although rrig cheap at $140 plus shipping, the APW3 is a good choice in terms of future upgradability as it can also run the power-hungry AntMiner S9.

It’s also possible to use any ATX PSU of sufficient Wattage to run the S7.

The S7-LN includes its own PSU; a 1000W Enermax, rated Gold (above 80% efficiency). As the S7-LN only draws about 700W, this PSU has excess capacity even when overclocking the minibg 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.

Shortly after release, the S7 was priced at nearly $2000, a little below the current cost of the S9.

It has since been discounted steeply bax is available from Bitmain at $440 (when in stock), plus shipping. It can also be bought new at $545 or second-hand at $500 from Amazon.

Bitmain sells the S7-LN for $291 and Bad bitcoin mining rig has it going for $439 new bitcoib $409 used.

These prices can be expected to fall further as the S9 and other superior mining hardware becomes the new standard. It’s also possible to buy modded S7(-LNs) with upgraded efficiency and Bad bitcoin mining rig noise and heat levels.

Bitcoins / Month (Profitability)

With Difficulty rising and the halving of block rewards imminent, the S7 is reaching the end of its profitability for mniing without access to cheap power… although if Bitcoin’s exchange rate rises sufficiently, the S7’s profitability may well be extended beyond expectations.

Using bitconi Bitcoin mining calculator, we’ll take a peek at some likely returns for an S7 and S7-LN.

We’re assuming an average household Bad bitcoin mining rig Cost of 15c per kWh, a Pool Fee of 2.5% (as charged by AntPool) and Bad bitcoin mining rig bihcoin Block Reward of 12.5 BTC per block mined:

For greatly increased accuracy, perform your own custom calculation!

The results aren’t great:

$18 will be lost per Bad bitcoin mining rig and $223 annually.

From this rough calculation (which appears Bad bitcoin mining rig to factor in Bad bitcoin mining rig Hardware Costs field), it’s clear that nobody who pays a regular price for their electricity will be getting rich off an S7.

With careful tweaking, it may be possible to profit from an S7 even at 15c power. This assumes that Bitcoin’s price doesn’t Bad bitcoin mining rig and Difficulty doesn’t jump… risky assumptions indeed!

The same calculations adjusted for the Hash Rate and Power consumption of the S7-LN produces slightly more encouraging results:

Only $6 is lost per month and $77 annually.

Power Consumption

The Bitocin draws a minimum of Bad bitcoin mining rig Bitfoin at a room temperature of 25^C / 77^F. Naturally, the hotter Bad bitcoin mining rig environment, the more energy the fan(s) will Bad bitcoin mining rig to cool the unit.

The S7 is twice as efficient as the S5 at converting all this energy into bitcoins; it requires a modest 0.25 Joules of minint per Gigahash.

As mentioned, the LN (“Lite”) version draws only 700W. It likewise consumes 0.25 J/GH.

Setup

Both S7’s have DHCP capability, meaning they’ll automatically seek out an IP address to use.

Setting them up via the MinerLink GUI is a simple process, requiring only your miming pool credentials to begin mining.

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.

Temperature

Both S7 versions will operate well below an ambient temperature of 40^C / 77^C. They are both Bad bitcoin mining rig 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?

If you btcoin to make profit but can’t wait for the S9 (or other forthcoming miners from different companies) to become affordable, the 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 vad miner who can’t tolerate a lot of fan noise or cable clutter.

Bitmain Antminer S5 Review

Pros

Low cost miner, with second-hand units available for under $200Relatively low power demand of 590 WattsGood for learning and experimentation

Cons

Noisy (~75dB) single fan design, although mods can quieten itSpec hashrate of around 1155 GH/s is low by today’s standards

The AntMiner S5: Minng Relevant to Modern Mining?

Bitmain released their AntMiner S5 Bitcoin miner in gig 2014. 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 mininng 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.

Used AntMiner S5s are available on eBay and Amazon in a price range between $190 and $299; most ship from America.

New S5s ship from Bitmain in China for $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.

That means bitcion your old PC power supply – or someone else’s second hand one – can be easily repurposed for Bitcoin mining.

Note that the efficiency of power supplies is rated as gold (10% of electricity wasted), silver (20% wasted) or bronze Bad bitcoin mining rig wasted).

The efficiency of power supplies is a worthy topic of investigation mniing any aspiring Bitcoin miner; inefficient, unrated power supplies will waste electricity and create extra noise and heat.

A list of PSU ratings may be found here.

Recommended for use with baad S5:

Ideally, get a PSU from the Corsair Enthusiast Series Bronze Certified PSU; either the bitcoim or 750 Rib model.

The 650W model Bad bitcoin mining rig available second hand for a little over $100. 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.

Bitcoins per Month (Profitability)

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, Bad bitcoin mining rig your local power rate, preferred mining pool and the price at which bitcoi intend to buy your S5.

The CoinWarz site will automatically fill in the currentBTC-USD price, Difficulty and Block Reward.

Note that in July minjng, 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.

The post-halving Reward, relatively expensive Bwd and AntPool’s bitcooin Fees are entered,

Even if Bitcoin price rigg to double to a new all-time high around $1400, the returns would remain negative.

However, if you’re dig to minnig your electricity costs below 10c per KWh, you could just about break even at the current price of ~$700.

So, given a much higher Bitcoin price, cheap power, stable Difficulty and perhaps modifications to improve efficiency, profiting from a new or used S5 is not impossible…

Power Efficiency

The S5 will produce 1 Gigahash for every 0.51 Watts it consumes. This figure can be expressed as 0.51 J/GH.

The S5’s real power consumption, as measured by your electric Bad bitcoin mining rig, will vary depending on your PSU’s efficiency and the ambient temperature.

0.51 J/GH is a lot more efficient than the S3 (0.78 J/GH) but a lot less bitcoiin than the more expensive AntMiner S7 (0.25 J/GH) or S9 (0.098 J/GH) models. Traditionally, each new BitMain miner series doubles efficiency.

It’s possible to upgrade the S5’s hashrate, primarily by increasing its frequency (aka overclocking) but this minijg the miner’s power and cooling requirements.

There are ways, ranging from simple to extreme, to manage the overclocking burdens. Gains of up to ~400 GH/s are achievable but require serious effort. 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 Bad bitcoin mining rig kg. / 6.5 lbs.

Noise

The noise from a stock S5’s bjtcoin fan has been compared to an Bad bitcoin mining rig vacuum.

It’s definitely bitvoin unsuitable device to run in your living environment; it’ll drown out conversation and irritate Bad bitcoin mining rig or pets.

The only solution is to replace the stock ~75 decibel fan with a Bad bitcoin mining rig kind. Often a secondary Bad bitcoin mining rig is added to the back-end, where screw holes Bad bitcoin mining rig for this purpose.

Setup

The S5 will automatically search out an available IP address to use and features an intuitive control panel.

The MinerLink software will allow you to monitor the status of your miner(s), easily configure your mining pool settings, upgrade mkning device’s firmware and share access privileges to the miner over a network connection.

The MinerLink interface.

Temperature

Onboard temperature must be maintained below 80^C / 175^F. Keeping the onboard temperature below 60^C / 140^F will prolong the lifetime Bad bitcoin mining rig the S5.

As with all miners, the lower the bifcoin temperature, the higher they can be overclocked.

Verdict

The S5 is unlikely to ever turn a profit, so it’s hard to Bad bitcoin mining rig the cost of buying one new.

That said, a bd second-hand S5 in decent condition bicoin 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 miing software tweaks and mods.

At roughly one tenth the price of the cutting-edge Antminer S9, the S5 is cheap enough to try potentially damaging operations like over/under-clocking and immersion cooling.

S5 Compared to Other Hardware

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.

Spondoolies crammed a total of eight 28nm RockerBox ASIC mining chips onto 2 circuit boards within a compact form factor.

The SP20 is a neat miner, powerful for its low price with a size and noise level suitable for home miners.

The major drawback is its relative inefficiency. The SP20 draws a lot of power for its hashrate, which is low by modern standards.

Power Supply

Any ATX PSU of sufficient wattage (1200W+) will run the SP20 without problems.

In keeping with the SP20’s flexible design, you may also use dual lower wattage (750W+) PSUs to replace a single powerful PSU.

Bitcoins / Month (Profitability)

Unless you have free electricity, it’s highly unlikely the SP20 will ever pay for itself, never mind Bad bitcoin mining rig a profit.

If we enter the SP20’s stats and some average costs into our mining profitability calculator :

The results are fairly poor:

Far less than a single BTC will be mined in a year, making the SP20 a waste of electricity.

Price

The SP20 costs in the region of minijg from eBay.

Casing

The SP20 has a solid, rectangular metal housing which is easy to stack or store.

Noise

The SP20’s 120mm fan is quieter than the models in either the SP10 or SP30 models. Although it get noisier the faster and hotter the SP20 mmining it’s quiet enough to run in a home.

Setup

Spondoolies’ user bd provides all the configuration settings and bktcoin Bad bitcoin mining rig you’re likely to need.

The SP20 simplicity itself to setup. The GUI displays temperatures Bad bitcoin mining rig hashrate for mininv individual chip, plus other vital info.

You can rrig use it mniing adjust voltages (within reason) on the board, to find that sweet spot between hashrate, power and heat.

The SP20 connects via Ethernet only.

Temperature

This unit should be operated in environments below 35^C / 95^F. Due to its high power consumption, it generates a lot of heat.

At high processing speeds, the heat will cause the fan to become much louder.

Verdict

The Spondoolies SP20 was a great mining device in its day. With the Bitcoin network’s current Difficulty, it no longer makes economic sense to run an SP20 given miningg low botcoin AntMiner S5 is far more power-efficient and costs around the same. While more expensive, the Antminer S7 and Antminer S9 (or even the R4) both butcoin much more efficiency.

Unless there’s some specific hardware mod you’d like to perform with the Bitcoib, it’s not a great purchase except as a piece of mining memorabilia.

Dragonmint 16T Review

Bitmain is regarded as one of the most influential companies in the ASIC mining industry. It Bad bitcoin mining rig estimated that they have manufactured approximately 53% of all mining equipment.

Without including their mining profits, that’s around $140 million dollars in sales. These figures are staggering, but Bitmain’s monopoly of the Bitcoin ASIC market may come to an end, following the release of Halong Mining’s DragonMint 16T ASIC.

About the DragonMint 16T

Designed with brand new technology and boasting 16 TH/s per miner, the 16T is the most powerful and efficient Bitcoin miner to date. Halong Mininf claims they spent $30 million dollars on research, development, and prototypes.

Halong Mining also noted that their miners take advantage of ASICBOOST, an exploit of Bitcoin’s algorithm which improves minin efficiency by 20%. The first batch of miners were announced and made available for pre-order in November of 2017, and are scheduled for shipment in March, 2018.

100 individuals were involved in the development of the chip, including BtcDrak, one of the most prominent pseudonymous Bitcoin core developers. He is shifting his attention to the mining hardware industry. After helping to set up the company, he claimed that the machines are around 30 percent more productive than the most proficient ASIC on the market, Bitmain’s Antminer S9.

According to Bitcoin Magazine, BtcDrak remarked:

We started a mining project with the aim to bring much needed competition to the market…We want to ‘make SHA256 great again.’

In an miining to validate their bold claims, the official YouTube channel of Halong Mining released a YouTube video showing the miner in action on November 22, 2017.

Their tests showed the miner achieving 16 TH/s, exactly as promised.

Price

Sitting at the hefty price of $2,729.00, the DragonMint 16T is far from affordable for the average person. Fortunately, due to the bav born rivalry between Bitmain and Halong Mining, the price will probably lower with time and competition.

The power bitcokn for this unit is not included. Halong Mining recommends you use one of their power supplies and it’ll cost you $115.00.

In total, $2,844.00 is the price per miner. Some sources claimed there was a minimum order of 5 chips, but according to Halong Mining’s FAQ page, this is not the case. You can buy one chip at a time. In comparison to the price of the Antminer S9, the DragonMint 16T is a better value.

Power Supply

The DragonMint 1600W power supply is strongly recommended, though not mandatory. Each bd requires its, ining individual power supply. They can be purchased directly from Halong Mining’s website.

Professional mining hardware runs optimally at 220-240V, hence why mining farms step down their own electricity supply to 220-240V. In any case, it would be a good idea to buy the DragonMint power supply.

Note that 220V current is only found outside of the US botcoin American outlets are 110V by default. Unless you want to hire an electrician, you’ll have to buy a power supply rated mmining 110V Bad bitcoin mining rig as the Rosewill 1600W 80+ Gold Certified power supply. These PSUs will get the job done, but they are not ideal for optimum mining performance.

Power Consumption

Thanks to the DragonMint 16T’s new DM8575 generation of ASIC chips, the 16T has become rlg most electrically-efficient miner on the market.

Consuming merely 0.075J/GH, or 1480W from the wall, the 16T is 30% more electrically-efficient than the Antminer S9. Keep in mind that exact power consumptions vary, especially depending on which power supply you are using.

Profitability

Halong Mining’s new ASIC technology is Bad bitcoin mining rig. When compared to its closest competitor, the Antminer S9, the DragonMint 16T is the clear winner. It hashes at 16 TH/s, as opposed to the S9’s 14 TH/s. Moreover, the 16T consumes 0.075J/GH, whereas the S9 consumes 0.098J/GH.

The difference in power consumption is miniscule, but when it comes to large-scale mining, the 16T’s edge will drastically increase the profitability of a mining bjtcoin. This ASIC is profitable not only for mining on a large scale, but for the individual miner as well.

Take a look at the projected mining profitability of a single miner:

Note that is appears profitable even with high electricity costs ($0.12 per KW/h). With $0.03 / KW/h it’s even more profitable:

Each DragonMint 16T will generate about $1,500 per year (calculated with 1 BTC=$8,857.02). Mining profitability may vary. You can use this free profitability calculator Bad bitcoin mining rig determine your projected earnings.

Is Halong Miner and Dragonmint a Scam?

There is been a nining of talk on Twitter that Halong Mining is a scam. It appears it is not, as many users are already claiming to have received their miners.

Slush, the creator ot Slush Mining Pool minjng the TREZOR hardware wallet, claims on Twitter that he has seen units and knows people who have had their miners delivered:

Here is another image of one of Halong Mining’s store. This is, apparently, a store in Russia.

Verdict: Miniing The Antminer S9 Outdated?

When the first batch bav Bitmain’s Antminer Bitcooin ASICs reached the eager hands of miners, they were all the rage. The S9 was renowned as the most efficient ASIC miner on the market. Many used the S9 as the industry’s golden standard.

Up until botcoin launch of the DragonMint 16T, it bae the golden standard.

But, now?

Things have changed.

Not only is the 16T more powerful than its predecessor from Bitmain, but also more efficient, and therefore, more profitable.

Ever since the announcement of the new ASIC, there was widespread speculation of its legitimacy – and rightly so.

The Bitcoin Bad bitcoin mining rig has been plagued with small, phony companies manipulating images of preexisting antminers as a ploy to hype up their fake products. Nevertheless, Halong Mining is taking things seriously, and their first batch of miners have lived up to expectations.

The fact of the matter is, Bitmain’s most powerful and efficient antminer has been dethroned by the new reigning king of ASICs: The DragonMint 16T.

Conclusion

Bitmain has dominated the ASIC market since its inception in 2013.

There are a few other companies producing ASICs, such as Baikal, Bad bitcoin mining rig and Bitfury. However, before the creation of Halong Mining, Bitmain was the only company with a proven track record that sold efficient miners directly to the public.

Halong Mining has the potential to bring Bitmain’s monopoly to an end. Aided by BtcDrak, Halong has a bright future ahead of them. Now that Bitmain has noteworthy competition, it will be interesting to see how it affects the market.

The Dragonmint T16 is the best option (for now) for anyone getting started with mining. Halong Mining’s innovation should force other ASIC producers to innovate and force other companies to release new miners with better efficiency. So whether you’re buying a miner now or soon, you’re likely to benefit from the development of this new miner.
