Bitcoin Mining Hardware Guide

The best Bitcoin mining hardware has evolved dramatically since 2009

At first, miners used their central processing unit (CPU) to mine, but soon this wasn't fast enough and it bogged down the system resources of the host computer. Miners quickly moved on to using the graphical processing unit (GPU) in computer graphics cards because they were able to hash data 50 to 100 times faster and consumed much less power per unit of work.

During the winter of 2011, a new industry sprang up with custom equipment that pushed the performance standards even higher. The first wave of these specialty bitcoin mining devices were easy to use Bitcoin miners were based on field-programmable gate array (FPGA) processors and attached to computers using a convenient USB connection.

FPGA miners used much less power than CPU's or GPU's and made concentrated mining farms possible for the first time.

Today's modern and best bitcoin mining hardware

Application-specific integrated circuit (ASIC) miners have taken over completely. These ASIC machines mine at unprecedented speeds while consuming much less power than FPGA or GPU mining rigs. Several reputable companies have established themselves with excellent products.

Bitcoin Mining Hardware Comparison

Currently, based on (1) price per hash and (2) electrical efficiency the best Bitcoin miner options are:

AntMiner S7

AntMiner S9

Best Bitcoin Mining Hardware

Two major factors go into determining the best bitcoin mining hardware: (1) cost and (2) electricity efficiency.

Bitcoin mining is difficult to do profitably but if you try then this Bitcoin miner is probably a good shot.

ASIC Bitcoin Mining Hardware

Application-specific integrated circuit chips (ASICs) are bitcoin mining hardware created solely to solve Bitcoin blocks. They have only minimal requirements for other normal computer applications. Consequently, ASIC Bitcoin mining systems can solve Bitcoin blocks much quicker and use less less electricity or power than older bitcoin mining hardware like CPUs, GPUs or FPGAs.

As Bitcoin mining increases in popularity and the Bitcoin price rises so does the value of ASIC Bitcoin mining hardware. As more Bitcoin mining hardware is deployed to secure the Bitcoin network the Bitcoin difficulty rises. This makes it impossible to profitably compete without a Bitcoin ASIC system. Furthermore, Bitcoin ASIC technology keeps getting faster, more efficient and more productive so it keeps pushing the limits of what makes the best Bitcoin mining hardware.

Some models of Bitcoin miners include Antminer S5, Antminer U3, ASICMiner BE Tube, ASICMiner BE Prisma, Avalon 2, Avalon 3, BTC Garden AM-V1 616 GH/s, VMC PLATINUM 6 MODULE, and USB miners.

Bitcoin Mining Software

Now that you already know about the best Bitcoin mining hardware, we’re going to talk about Bitcoin mining software.

What is Bitcoin Mining Software?

Bitcoin mining hardware handles the actual Bitcoin mining process, but:

Bitcoin mining software is equally as important.

• If you are a solo miner: the mining software connects your Bitcoin miner to the blockchain.
• If you mine with a pool: the software will connect you to your mining pool.
• If you are cloud mining: you do not need mining software.

Importance of Bitcoin Mining Software

The main job of the software is to deliver the mining hardware’s work to the rest of the Bitcoin network and to receive the completed work from other miners on the network.

Bitcoin mining software monitors this input and output of your miner while also displaying statistics such as the speed of your miner, hashrate, fan speed and the temperature.

Bitcoin Wallets

One of the most important things you will need before using any kind of Bitcoin mining software is a wallet.

This is because all Bitcoin mining software will ask you for a Bitcoin address that will be used to send your mining rewards and payouts. Once you create or download a wallet you will be able to get a Bitcoin address from your wallet.

There are many Bitcoin wallets, but these are the ones we recommend if you are just starting out:

• Ledger Nano S – Secure Bitcoin hardware wallet for all platforms.
• Electrum – Simple Bitcoin wallet that works on Mac, Windows, and Linux.
• Mycelium – The most popular Bitcoin wallet on Android.
• breadwallet – The most popular Bitcoin wallet for iOS.

If you expect to earn a lot of money through mining then it would be smart to purchase a more secure wallet: a hardware wallet.Now that we understand mining software and how it helps in the mining process, and you got your Bitcoin wallet and address, let’s look at different software on different operating systems.

Bitcoin Mining Software for Windows

Bitcoin Miner

You can use Bitcoin Miner on Windows 10 and Windows 8.1.

It has an easy to use interface, power saving mode, mining pool support and fast share submission.

One useful feature is the profit reports feature because this feature will help you know if your mining is profitable or not. The latest version of this software is Bitcoin Miner 1.27.0.

BTCMiner is an Open Source Bitcoin Miner for ZTEX USB-FPGA modules 1.5.

BTCMiner comes with the following features:

• Dynamic frequency scaling in that BTCMiner automatically chooses the frequency with the highest rate of valid hashes
• Ready-to-use Bitstream i.e. no Xilinx software or license required.

It also comes with supported FPGA boards which contain a USB interface used for communication and programming.

CGMiner is arguably the most famous and commonly used among Bitcoin miners at the moment.

CGMiner is based on the original code of CPU Miner.

This software has many features but the main ones include:

• fan speed control
• remote interface capabilities
• self-detection of new blocks with a mini database
• multi GPU support
• CPU mining support

BFGMiner is more or less the same as CGMiner.

Cash Out your Coins

Once you have this setup and are mining, you may need to cash out some of your coins in order to pay off your expenses such as electricity.

For this you can use Buy Bitcoin Worldwide to find a Bitcoin exchange in your country.

How Does Cloud Mining Bitcoin Work?

If you want to invest in bitcoin mining without the hassle of managing your own hardware, there is an alternative. You can use the cloud to earn your coins.

Put very simply, cloud mining means using (generally) shared processing power run from remote data centres. One only needs a home computer for communications, optional local bitcoin wallets and so on.

However, there are certain risks associated with cloud mining that investors need to understand prior to purchase.

Here's why you might want to consider cloud mining:

• A quiet, cooler home – no constantly humming fans
• No added electricity costs
• No equipment to sell when mining ceases to be profitable
• No ventilation problems with hot equipment
• Reduced chance of being let down by mining equipment suppliers.

Here's why you might not want to consider cloud mining:

• Risk of fraud
• Opaque mining operations
• Less fun (if you're a geek who likes system building!)
• Lower profits – the operators have to cover their costs after all
• Contractual warnings that mining operations may cease depending on the price of bitcoin
• Lack of control and flexibility.

Types of cloud mining

In general, there are three forms of remote mining available at the moment:

1. Hosted mining
   Lease a mining machine that is hosted by the provider.
2. Virtual hosted mining
   Create a (general purpose) virtual private server and install your own mining software.
3. Leased hashing power
   Lease an amount of hashing power, without having a dedicated physical or virtual computer. (This is, by far, the most popular method of cloud mining.)

How to determine profitability

We have previously covered ways to calculate mining profitability. However, the web services offered are designed to work with your hardware parameters, not cloud-mining parameters.

Even so, you can still use these calculators by thinking clearly about the costs involved. Profitability calculators (for example, The Genesis Block) often ask for your electricity costs, and sometimes the initial investment in hardware. Effectively, you are being asked for your ongoing costs and your one-off investments.

Therefore, since the provider, not you, is paying the electricity bills, you can enter the monthly mining bill in place of the electricity cost.

The conversion process isn't completely straightforward, though. In the case of hardware miners, you can work out the monthly running cost by multiplying your electricity charge (ie: $ per KWh) by the power consumption of the unit and by a conversion factor of 0.744 (the ratio of seconds per month to joules of energy per KWh).

But, for cloud mining calculations, you need to do the opposite, because the provider gives you an (effective) monthly running cost. Hence, you need to calculate an equivalent cost per kilowatt hour to feed into the mining calculator. This is done by dividing (not multiplying) the monthly running cost by the 0.744 conversion factor mentioned above.

Risk vs reward

When engaging in any type of cryptocurrency mining there are risks, but profitability is possible if you make the right choices. In this article, we've given you some pointers on how to decide which way to go.

In your test calculations, you will likely see that some cloud mining services will be profitable for a few months, but, as the difficulty level of bitcoin increases, you would probably start to make a loss in four to six months and beyond.

A possible remedy to this situation is to reinvest what you have made into maintaining a competitive hashing rate, but this is highly speculative.

As mentioned above, the risk of fraud and mismanagement is all too common in the cloud mining space. Investors should only invest in cloud mining if they are comfortable with these risks – as the saying goes, never invest more than you are willing to lose.

Investigate social media channels, speak with former customers and ask pointed questions of operators prior to investing. Ultimately, you should practice the same kind of due diligence that you would for any investment.

Bitcoin Mining Hardware ASICs

Hobby Bitcoin mining can still be fun and even profitable if you have cheap electricity and get the best and most efficient Bitcoin mining hardware.

It’s important to remember that 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 are better off buying bitcoins.

Bitcoin Mining Hardware Comparison

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.

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

The Dragonmint 16T miner.

Originally, Bitcoin’s creator intended for Bitcoin to be mined on CPUs (your laptop or desktop computer). However, Bitcoin miners discovered they could get more hashing power from graphic cards. Graphic cards 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 all serious Bitcoin mining is performed on dedicated Bitcoin mining hardware ASICs, usually in thermally-regulated data-centers with access to 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 0.4527678% daily increase in network hash rate. 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 0.3403% per day over the past year. 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 to Find the Best Bitcoin Miner

There are some important 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 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.

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 a miner based on only price or only hash rate. The best ASIC miner is the most efficient bitcoin miner. Aim for value.

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. One 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.

Just Want Bitcoins?

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.

Get $10 worth of free bitcoins when you buy $100 or more at Coinbase.

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 – 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 of 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 of cooling fans to keep your hardware working.

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 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

Using a Bitcoin USB miner with your computer was once a profitable way to mine bitcoins. Today, however, USB miners don’t generate enough hashing power to mine profitably. If you just want to get a Bitcoin miner USB to learn, eBay is a good place to buy a cheap Bitcoin miner.

Halong Mining

The world of crypto was in disbelief when Halong Mining, a new ASIC startup, announced their brand new Dragonmint T16. Halong claimed 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 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. 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 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. 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 Twitter 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 Bitcoin 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 TH/s, it is the most 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 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? An incredibly profitable ASIC! The T16 is 30% more efficient than its competition.

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 Antminer 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, next 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. 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.

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

ASICs rendered GPUs useless. 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 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.

Beginner’s Guide to Mining Bitcoins

Last updated on May 18th, 2018 at 03:08 pm

One of the biggest problems I ran into when I was looking to start mining Bitcoin for investment and profit was most of the sites were written for the advanced user. I am not a professional coder, I have no experience with Ubuntu, Linux and minimal experience with Mac. So, this is for the individual or group that wants to get started the easy way.

1. Get a Bitcoin mining rig

Bitcoin mining is a very competitive niche to get into. As more and more miners come on board with the latest mining hardware the difficulty to mine increases each day. Before even starting out with Bitcoin mining you need to do your due diligence. This means you need to find out if Bitcoin mining is even profitable for you.

The best way to do this is through the use of a Bitcoin mining calculator. Just enter the data of the Bitcoin miner you are planning on buying and see how long it will take you to break even or make a profit. However, I can tell you from the get go that if you don’t have a few hundred dollars to spare you probably won’t be able to mine any Bitcoins.

Once you’ve finished with your calculations it’s time to get your miner. Make sure to go over our different Bitcoin mining hardware reviews to understand which miner is best for you. Today, the Antminer S9 is the newest and most powerful miner.

Select miner

AntMiner S9

Antminer R4

Antminer T9

AntMiner S7

AntMiner S5

Antrouter R1

As a side note it’s important to state that in the past it was possible to mine Bitcoins with your computer or with a graphics card (also known as GPU mining). Today however, the mining niche has become so competitive that you’ll need to use ASIC miners – special computers built strictly for mining Bitcoins.

2. Get a Bitcoin wallet

First thing you need to do is get a “Bitcoin Wallet“. Because Bitcoin is an internet based currency, you need a place to keep your Bitcoins. Once you have a wallet make sure to get your wallet address. It will be a long sequence of letters and numbers. Each wallet has a different way to get the public Bitcoin address but most wallets are pretty straight forward about it. Notice that you’ll need your PUBLIC bitcoin address and not your PRIVATE KEY (which is like a password for your wallet).

If you’re using a self hosted wallet (i.e. you downloaded a program to your computer and are not using an internet based service) there’s one additional very important step. Make sure you have a copy of the wallet.dat file on a thumb drive and print a copy out and keep it in a safe location. You can view a tutorial on how to create a secure wallet here. The reason is that if you computer crashes and you do not have a copy of your wallet.dat file, you will lose all of your Bitcoins. They won’t go to someone else, they will disappear forever. It is like burning cash.

3. Find a mining pool

Now that you have a wallet you are probably roaring to go, but if you actually want to make Bitcoin (money), you probably need to join a mining pool. A mining pool is a group of Bitcoin miners that combines their computing power to make more Bitcoins. The reason you shouldn’t go it alone is that Bitcoins are awarded in blocks, usually 12.5 at a time, and unless you get extremely lucky, you will not be getting any of those coins.

In a pool, you are given smaller and easier algorithms to solve and all of your combined work will make you more likely to solve the bigger algorithm and earn Bitcoins that are spread out throughout the pool based on your contribution. Basically, you will make a more consistent amount of Bitcoins and will be more likely to receive a good return on your investment.

When choosing which mining pool to join you will need to ask several questions:

• What is the reward method? – Proportional/Pay Per Share/Score Based/PPLNS
• What fee they charge for mining and withdrawal of funds?
• How frequently they find a block (means how frequently I get rewarded)?
• How easy it is to withdraw funds?
• What kind of stats they provide?
• How stable is the pool?

To answer most of these questions you can use our best Bitcoin mining pools review or this excellent post from BitcoinTalk. You can also find a complete comparison of mining pools inside the Bitcoin wiki. For the purpose of demonstration I will use Slush’s Pool when mining for Bitcoins. Once you are signed up with a pool you will get a username and password for that specific pool which we will use later on.

Follow the link to go to their site and click the “Sign up here” link at the top of their site and follow their step by step instructions. After you have your account set up, you will need to add a “Worker”. Basically, for every miner that you have running, you will need to have a worker ID so the pool can keep track of your contributions.

4. Get a mining program for your computer

Now that you’ve got the basics covered we’re almost ready to mine. You will need a mining client to run on your computer to that you will be able to control and monitor your mining rig. Depending on what mining rig you got you will need to find the right software. Many mining pools have their own software but some don’t. You can find a list of Bitcoin mining software here.

I’m using a mac so I will use a program called MacMiner. The most popular program I’ve found for a PC are BFGMiner and 50Miner . If you want to compare different mining software you can do this here.

5. Start mining

OK, so hopefully now everything is ready to go. Connect you miner to a power outlet and fire it up. Make sure to connect it also to your computer (usually via USB) and open up your mining software. The first thing you’ll need to do is to enter your mining pool, username and password.

Once this is configured you’ll basically start mining for Bitcoins. You will actually start collections shares which represent your part of the work in finding the next block. According to the pool you’ve chosen you will be paid for your share of coins – just make sure that you enter your address in the required fields when signing up to the pool. Here’s a full video of me mining in action:

Conclusion – perhaps it’s better just to buy the coins?

To conclude this article here’s something to consider. Perhaps it would be more profitable for you to just buy Bitcoins with the money you plan to spend on Bitcoin mining. Many times just buying the coins will yield a higher ROI (return on investment) than mining. If you want to dig into this a bit deeper here’s a post about exactly that.

I contacted Samsung thru their Samsung Tutor app on my phone. I gave their Technican access to my phone to see if there was a problem with my phone that stopped the Yahoo Search App from working. He went to Yahoo and I signed in so he could try to fix the Yahoo Search App not working. He also used another phone, installed the app from the Google Play Store to see if the app would do any kind of search thru the app. The Yahoo Search App just wasn't working.

I also had At&t try to help me because I have UVERSE for my internet service. My internet was working perfectly. Their Technical Support team member checked the Yahoo Search App and it wouldn't work for him either.

We can go to www.yahoo.com and search for any topic or website. It's just the Yahoo Search App that won't allow anyone to do web searches at all.

I let Google know that the Yahoo Search App installed from their Google Play Store had completely stopped working on May 18, 2018.

I told them that Yahoo has made sure that their Yahoo members can't contact them about anything.

I noticed that right after I accepted the agreement that said Oath had joined with Verizon I started having the problem with the Yahoo Search App.
No matter what I search for or website thru the Yahoo Search App it says the following after I searched for
www.att.com.

I tried to search for things like www.homedepot.com. The same thing happened. It would say WEBPAGE NOT AVAILABLE. The only thing that changed were all the upper and lower case letters, numbers and symbols.
Then it would again say
could not be loaded because:
net::ERR_CLEARTEXT_NOT_PERMITTED

This is the same thing that happened when Samsung and At&t tried to do any kind of searches thru the Yahoo Search App.

Yahoo needs to fix the problem with their app.

The ETF and You: What Bitcoin’s Big News Means 07.03.2016.

The latest news in the Bitcoin space is one that has been in the making for four years: the Winklevoss’ twins Bitcoin ETF will soon be accepted, or rejected, by the Securities and Exchange Commission (the SEC). This decision will leave ripples in Bitcoin’s history, and it’s the first step to legitimizing Bitcoin’s acceptance with the general public.

Bitcoin: the Technology That Just Won’t Die 17.01.2017.

Like most Bitcoin fans out there, I talk about Bitcoin a lot. From the person sitting next to me on the plane to the waiter serving my table drinks, every chance I get I end up talking about Bitcoin. This isn’t something I intentionally force on people, it’s something that just naturally ends up fitting into so many different conversations and every time a Bitcoin conversation starts, I eventually am asked the same question.

Best Bitcoin Mining Hardware for 2018 – Bitcoin Miner Reviews

The following page reviews the best hardware available today in order to make some sort of a profit with Bitcoin mining.

If you’re completely new to Bitcoin mining please read our “Is Bitcoin mining still profitable?” post before moving on. It will give you a good idea about the profitability of mining and will make you think twice before entering this very competitive niche.

If however, you are aware of the competitive nature of Bitcoin mining and still want to get in the game, here you will be able to find the best Bitcoin mining hardware available. The good news is that there are not many mining hardware companies left that make ASIC miners so choosing will probably be easy. That’s also the bad news. Even though many websites state long lists of Bitcoin mining hardware, only a handful of mining rigs can deal with the rising Bitcoin mining difficulty that’s out there these day.

How to compare Bitcoin miners

Below is a side by side comparison of all relevant miners. Underneath the table you’ll be able to see a summarized review of each of the miners. Keep in mind that in order to see how profitable you can be with any Bitcoin miner you’ll need to use a Bitcoin mining calculator based on your electricity cost, the Bitcoin exchange rate and the increase in difficulty throughout time. Since not all of these variables are known you will have to guess some as best as you can.

Antminer S5 Bitcoin Miner Summarized Review

The Antminer S5 is the entry level Bitcoin miner for someone who isn’t ready to part away with more than a few hundred bucks. Users who have purchased it seem mostly pleased with the device. However this is an outdated device and with today’s mining difficulty and decreasing block reward you won’t make more than 0.05 BTC each money in revenue. This means you’ll need to run it for about one year and 8 months to get a full Bitcoin. Some customers also complained about the device being too noisy, but that’s just how a miner works – it’s loud and hot.

Avalon 6 BitcoinMiner Summarized Review

The Avalon 6 is a great contender for both S5 and S7 AntMiners. From the small number of reviews that can be found online people are saying that it’s not nearly as loud as your usual miner and the hash rate is pretty reasonable. However at the current price tag I see little reason to choose it over the competition, it’s $100 more than the S7 that brings to the table superior results.

Antminer S7 Bitcoin Miner Summarized Review

The Antminer S7 was the raining champion up until a few months ago. Even at today’s difficulty levels and with the block reward halving you can still make 0.15BTC a month. It’s not a lot at the moment but if the Bitcoin price continues to rise it may be a profitable investment.

However I wouldn’t suggest buying this rig due to the fact that it’s neither here nor there. It’s too expensive for an entry-level device and it’s too weak to generate any substantial amount of Bitcoins. Users who bought the device seem generally happy with it however it was first introduced on August 2015, so it’s not that new.

Antminer S9 Bitcoin Miner Summarized Review

The most advanced and most efficient Bitcoin miner today is the Antminer S9. If you’re serious about Bitcoin mining this is your rig. At the current difficulty this miner can mine around 0.02 Bitcoins every month which makes it seem like it would break even within a year. However we did not take into account the electricity costs, pool fees and hardware cost. Not to mention the fact the difficulty can rise and the Bitcoin price can drop.

It seems that even though this is the toughest miner out there, there’s only a small amount of time until it too will become outdated. Until that happens though, it looks like a pretty reliable piece of equipment.

Antminer R4 Bitcoin Miner Summarized Review

The Antminer R4 is intended for hobby mining – basically people who want to mine Bitcoins at home. Even though it can’t compete with the S9 it will probably be a good contender for the S7. The main advantage it has over other miners is the fact that it is has a specialized cooling unit that is much quieter than any other Bitcoin miner out there – since it’s made for a home environment.

According to our mining calculator this miner should break even in about 12 months. However if Bitcoin’s price continues to rise this miner may yet yield a good return on investment.

Avalon 7 Bitcoin Miner Summarized Review

The Aavalon 721 (or Avalon 7 as it is known commonly) is the latest Bitcoin miner supplied by Avalon in late 2016. It has a lower price tag than most of the advanced miners but is also less powerful. It seems to be a good choice for people who are looking for a cheaper entry level miner and don’t want to go for an Antminer S7.

According to our calculations, this miner should break even in about 24 months, making it a pretty risky investment. You can also connect up to 5 Avalon 721s in a row creating a powerful 30 TH/s mining rig.

Antminer T9 Bitcoin Miner Summarized Review

The Antminer T9 is a more reliable, cheaper version of the successful S9 model. However, the T9 uses almost 30% more power than the S9 making it much less attractive in terms of return on investment. If you want to get up and mining as soon as possible and reliability is more important to you than efficiency, then we’d say the T9 is a reasonable choice. If you don’t pay for power and just want a good, fast miner you can “fire up and forget,” the Antminer T9 will fit the bill nicely.

Mining Experiment: Running 600 Servers for a Year Yields 0.4 Bitcoin

Online backup provider iDrive (mascot shown above) conducted an experiment in which it used 600 quad-core servers to mine for Bitcoin. The result: Stick with custom ASICs. (Image: iDrive)

Can data centers tap unused server capacity to mine for Bitcoins? The question occurred to the team at the online backup service iDrive, which performs most of its customer backup jobs overnight, leaving its 3,000 quad-core servers idle for much of the day. So the company ran a test with 600 servers to see whether Bitcoin mining could become a secondary revenue stream.

The result: running Bitcoin mining software on those 600 quad-core servers for a year would earn about 0.43 Bitcoin, worth a total return of about $275.08 at current prices on major Bitcoin exchanges.

"Its a waste of time, so any other company thinking about mining with their infrastructure, learn from us," said iDrive's Matthew Harvey. "Don't do it. You need custom machines to effectively mine bitcoins and generate a real ROI."

The iDrive test-drive reinforced a common theme on Bitcoin mining forums: To earn money by mining, you need to invest in highly-customized computers using ASICs (Application Specific Integrated Circuits) to crunch data for creating and tracking bitcoins.

Bitcoin is sometime referred to as the “Internet of money,” a platform using cryptography and software to offer an alternative currency and payment-tracking system. At its heart is a huge distributed computing network that verifies each transaction. Participants in this online ledger are rewarded with new bitcoins, which are issued about every 10 minutes.

Miners Upgrade to Powerful Hardware

Over the past year, the computing power supporting the bitcoin network has soared. The cryptocurrency is now supported by a powerful global network backed by 150,000 petaflops per second of computing power, roughly 600 times the combined power of the all the supercomputers in the Top500 list. Practitioners of Bitcoin mining – the term for using data-crunching computers to earn newly-issued virtually currency – are adopting more powerful hardware, pooling their efforts and seeking to slash their power bills.

Most serious Bitcoin miners have graduated from CPUs and GPUs to specialized chips such as FPGAs (Field Programmable Gate Arrays) or ASICs that can be optimized for specific workloads. This has led to the emergence of a new class of hardware vendors selling custom hardware for bitcoin mining.

The horsepower required to succeed in Bitcoin is highlighted by the iDrive simulation, which used 600 servers.

"Our study projected a year of mining at 100 percent processing power 24/7 and the assumption that the difficulty of mining (the calculating of hashes) would increase linearly," iDrive noted in a blog post describing its experiment. "In the end, we learned a lot about the interesting process of bitcoin mining, however, for us, the pros did not outweigh the cons. So, IDrive decided to stick with that we do best."

They're not the only ones who've contemplated repurposing powerful equipment to pursue cryptocurrency, The 4,000-core Odyssey supercomputer at Harvard was secretly used to mine Dogecoin, the ironic virtual currency used primarily for online tipping. The covert miner has had their computing privileges at the university suspended.

Bitminter - bitcoin minting the easy way!

Sign up and point your ASIC machines to mint.bitminter.com:3333 with your user name and a dummy (x or 123) password. Or use a specific region:

• us1.bitminter.com:3333 (United States)
• us2.bitminter.com:3333 (United States)
• ca1.bitminter.com:3333 (Canada)
• eu1.bitminter.com:3333 (Europe)

A closer server can slightly reduce stale (rejected) work. A reject ratio around 0.10% is normal. Check live stats to see your reject ratio in the current shift.

If you have firewall issues try port 443 instead of 3333.

New users can mine with just the user name. That's because you start out with a worker that has the default setting enabled. To use a specific worker mine with your user name, an underscore, then a worker name, e.g. John_asic3. There is no password check. You can put X or 123 as password.

What is BitMinter?

Bitminter is a bitcoin mining pool that aims to make it easy for anyone to make bitcoins. Bitminter is one of the oldest pools. Since we opened in 2011 over 450 000 people have registered accounts with us. We hope that you will join us too!

What do I need?

ASICs took over in 2013. Mining one bitcoin with just a PC now takes millions of years. You'll want a 1 TH/s or faster ASIC machine to start a small mining-at-home operation. Have a look at Antminer from Bitmain and AvalonMiner from Canaan. Used ASICs are available at ebay and similar places.

Reward System

Your work is recorded in shifts. When we create a new block you get a share of the income proportional to how much of the work in the last 10 completed shifts is yours. This reward system is known as PPLNS with shifts. 99% of the mining income (including transaction fee income) is paid out to users. Donations are optional and will unlock various perks.
