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.

Bitcoin.com Now Offers Mining Servers at Discounted Rates

The mining sector within the bitcoin economy has grown exponentially as the digital currency’s value continues to make mining operations more lucrative. With the recent surge in bitcoin’s price and mining revenue, Bitcoin.com is offering discounted Avalon 6s and Bitmain Antminer S7s for purchases of 100 servers or more .

Bitcoin Mining More Profitable Than Ever

As the price of bitcoin continues to rise there are still significant benefits to using older mining devices especially if operators have access to low electrical costs. Currently, Bitcoin.com has connections to a large supply of older generation bitcoin mining servers which include the Bitmain’s Antminer S7 and Canaan’s Avalon 6. We are offering mining server purchases of 100 servers or more for less than $70 per TH/s (vs. $90+ per TH/s for new miners).

Used Mining Servers Available to Bitcoin.com Readers

Canaan-Creative’s Avalon 6 Series

The Avalon 6 bitcoin mining server which consists of 80 A3218 18nm chips was developed by the reputable mining manufacturer Canaan-Creative. The 3.65 TH/s mining servers can be tethered together in managed clusters utilizing the Avalon 6s USB hub connectors. The Canaan miners are controlled by a standard Raspberry Pi, and they are powered via 4 PCI-E 6 Pin adapters.

Canaan-Creative’s Avalon 6 Series

Canaan’s Avalon 6 has received great reviews since it was released and is said to be a “tough contender” among miners with roughly the same amount of TH/s. The miner’s reviews also say the versatile machine has many customization options that will bolster all types of mining set-ups and facilities.

Bitmain’s Antminer S7 Series

The Antminer series is well known among mining enthusiasts, and the S7 series is no different. The Antminer stock S7 utilizes 162 of the company’s BM1385 16nm ASIC chips at a hashrate of 4.86 TH/s. The miner is ideal for those who have access to low-cost electricity with the miner’s excellent power consumption using only 1210 Watts. The BM1385 ASIC chipsets typically produce 32.5 GHS per chip at optimal settings.

Bitmain’s Antminer S7 Series

Bitmain’s S7 also has solid reviews detailing the Antminer S7s performance. The S7 is known for being a “solid performing Bitcoin ASIC miner” that also allows for tweaks and modifications. Furthermore many have said the Antminer S7 is a reliable machine with controller options that are vigorous and has been considered one of the “best bitcoin mining servers available to end users” when it was released.

The Thriving Used Miner Market Grows More Attractive Worldwide

For operators with lower energy costs, the merits with purchasing older generation miners are significant. This is because they can offer a more profitable return on investment (ROI) due to the hardware’s substantially lower cost per terrahash, relative to new servers.

We think it’s an excellent chance for bitcoin enthusiasts and organizations to join the ever growing bitcoin mining economy and were pleased to offer some of the best prices in the industry.

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.

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.

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.

Repair the Yahoo Search App.

Yahoo Search App from the Google Play Store on my Samsung Galaxy S8+ phone stopped working on May 18, 2018.

I went to the Yahoo Troubleshooting page but the article that said to do a certain 8 steps to fix the problem with Yahoo Services not working and how to fix the problem. Of course they didn't work.

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

Bitcoin Mining Pools

Now that you have Bitcoin mining hardware, your next step is to join a Bitcoin mining pool.

What is a Mining Pool?

Mining pools are groups of cooperating miners who agree to share block rewards in proportion to their contributed mining hash power.

While mining pools are desirable to the average miner as they smooth out rewards and make them more predictable, they unfortunately concentrate power to the mining pool’s owner.

Miners can, however, choose to redirect their hashing power to a different mining pool at anytime.

Pool Concentration in China

Before we get into the best mining pools to join, it’s important to note that most mining pools are in China. Many only have Chinese websites and support. Mining centralization in China is one of Bitcoin’s biggest issues at the moment.

There are about 20 major mining pools. Broken down by the percent of hash power controlled by a pool, and the location of that pool’s company, we estimate that Chinese pools control

81% of the network hash rate:

The Biggest Mining Pools

The list below details the biggest Bitcoin mining pools. This is based on info from Blockchain’s pool share chart:

We strongly recommend new miners to join Slush Pool despite it not being one of the biggest pools. It was the first Bitcoin mining pool and remains one of the most reliable and trusted pools, especially for beginners.

BTC.com is a public mining pool that can be joined. However, we strongly recommend joining Slush Pool instead.

Antpool is a mining pool based in China and owned by BitMain. Antpool mines about 25% of all blocks.

ViaBTC is a somewhat new mining pool that has been around for about one year. It’s targeted towards Chinese miners.

Slush was the first mining pool and currently mines about 3% of all blocks.

Slush is probably one of the best and most popular mining pools despite not being one of the largest.

DiscusFish, also known as F2Pool, is based in China. F2Pool has mined about 5-6% of all blocks over the past six months.

BTC.top is a private pool and cannot be joined.

7. Bitclub.Network

Bitclub Network is a large mining pool but appears to be somewhat shady. We recommend staying away from this pool.

BTCC is a pool and also China’s third largest Bitcoin exchange. Its mining pool currently mines about 7% of all blocks.

Bitfury is a private pool that cannot be joined. Bitfury currently mines about 2% of all blocks.

10. BW Pool

BW, established in 2014, is another mining company based in China. It currently mines about 2% of all blocks.

Bitcoin Mining Pool Comparison

The comparison chart above is just a quick reference. The location of a pool does not matter all that much. Most of the pools have servers in every country so even if the mining pool is based in China, you could connect to a server in the US, for example.

Get a Bitcoin Wallet and Mining Software

Before you join a mining pool you will also need Bitcoin mining software and a Bitcoin wallet.

Mining Pools vs Cloud Mining

Many people read about mining pools and think it is just a group that pays out free bitcoins. This is not true! Mining pools are for people who have mining hardware to split profits.

Many people get mining pools confused with cloud mining. Cloud mining is where you pay a service provider to miner for you and you get the rewards.

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.

Which Countries Mine the most Bitcoins?

Bitcoin mining tends to gravitate towards countries with cheap electricity.

As Bitcoin mining is somewhat centralized, 10-15 mining companies have claimed the vast majority of network hash power.

With many of these companies in the same country, only a number of countries mine and export a significant amount of bitcoins.

China mines the most bitcoins and therefore ends up “exporting” the most bitcoins.

Electricity in China is very cheap and has allowed Chinese Bitcoin miners to gain a very large percentage of Bitcoin’s hash power.

It’s rumored that some Chinese power companies point their excess energy towards Bitcoin mining facilities so that no energy goes to waste.

China is home to many of the top Bitcoin mining companies:

It’s estimated that these mining pools own somewhere around 60% of Bitcoins hash power, meaning they mine about 60% of all new bitcoins.

Georgia is home to BitFury, one of the largest producers of Bitcoin mining hardware and chips. BitFury currently mines about 15% of all bitcoins.

Sweden is home to KnCMiner, a Bitcoin mining company based in Stockholm. KnCMiner currently mines about 7.5% of all bitcoins.

The US is home to 21 Inc., a Bitcoin mining company based in California.

21 runs a large amount of miners, but also sells low powered bitcoin miners as part of their 21 Bitcoin computer.

Most of the hash power from the 21 Bitcoin computers is pointed towards 21’s mining pool. 21 Inc. mines about 3% of all bitcoins.

Other Countries

The countries above mine about 80% of all bitcoins.

The rest of the hash power is spread across the rest of the world, often pointed at smaller mining pools like Slush (Czech Republic) and Eligius (US).

A Note on Pools

While we can see which mining pools are the largest, it’s important to understand that the hash power pointed towards a mining pool isn’t necessarily owned by the mining pool itself.

There are a few cases, like with BitFury and KnCMiner, where the company itself runs the mining operation but doesn’t run a mining pool.

Bitcoin miners can switch mining pools easily by routing their hash power to a different pool, so the market share of pools is constantly changing.

To make the list of top 10 miners, we looked at blocks found over the past 6 months using data from BlockTrail.

The size of mining pools is constantly changing. We will do our best to keep this posted up-to-date.

If you cloud mine then you don’t need to select a pool; the cloud mining company does this automatically.

Why are Miners Important?

Bitcoin miners are crucial to Bitcoin and its security. Without miners, Bitcoin would be vulnerable and easy to attack.

Most Bitcoin users don’t mine.

However, miners are responsible for the creation of all new bitcoins and a fascinating part of the Bitcoin ecosystem.

Mining, once done on the average home computer, is now mostly done in large, specialized warehouses with massive amounts of mining hardware.

These warehouses usually direct their hashing power towards mining pools.

Antpool Review

Despite recent controversy, Antpool remains the largest Bitcoin mining pool in terms of its Bitcoin network hash rate. Antpool holds roughly 15% of the total hash rate of all Bitcoin mining pools.

About Antpool

Antpool mined its first block in March 2014, meaning that it emerged roughly four years after the first mining pool; Slushpool.

Antpool is run by Bitmain Technologies Ltd., the world’s largest Bitcoin mining hardware manufacturer, and a large portion of their pool is run on Bitmain’s own mining rigs.

Antpool supports p2pool and stratum mining modes with nodes that are spread all over the world to ensure stability (US, Germany, China etc.).

Also, Antpool’s user interface is surprisingly slick considering that the underlying company thrives mostly off of hardware sales.

How to Join Antpool

The pool is free to join and the process is simple.

First, you need to acquire Bitcoin mining hardware. Then you need to download mining software. If you need help deciding, I suggest you take a look at our hardware and software guides.

Hardware is important because it determines the size of your contribution to the pool’s hash rate. Software is important because it enables you to direct your hardware’s hash power towards the pool you prefer. So make sure to make the right choice in order to optimize your rewards.

What are Antpool’s Fees?

Antpool claims that it does not charge any fees for using its pool. Although there is some truth to this claim, it is not 100% correct.

While Antpool does not directly charge fees, it also does not disclose the Bitcoin transaction fees that are collected. Basically, clients are left in the dark. Currently, every Bitcoin block has a 12.5 BTC reward which Antpool does share with you when it finds a block.

Lately, however, Bitcoin transaction fees have been rising and an additional 1-2 bitcoins are collected per block by pools. At this time, Antpool keeps 1-2 bitcoins form transaction fees for itself, which are not shared with miners who have hash power pointed toward the pool.

It can be argued that these rates prevent the service from being usable for small-time and big-volume users. Consequently, some users on bitcointalk.org heed that the undisclosed fees make the service unwise to use for the time being.

What is the Payout Threshold?

The pool does not appear to have a payout threshold and pays out every day around 10 AM UTC.

The minimum withdrawal amount is 0.0005 BTC (other sources say 0.001 BTC).

Can you do Solo Mining on Antpool?

Solo mining means you mine for bitcoins without joining a pool. So if you use Antpool you are not solo mining by default.

Generally, you will receive more frequent payouts by joining a pool.

What is the Controversy around Antpool?

Antpool has refused to enable arguably beneficial upgrades to Bitcoin for reasons based on claims that have been largely disproved. Notably, this has taken place with somewhat of a vindictive attitude.

More specifically, the controversy revolves around Segwit – a feature that requires miner activation to be enabled. Despite the fact that most Bitcoin users want this feature activated, Antpool, among other pools, appears to be blocking this feature.

Antpool began signaling for Bitcoin Unlimited in early March 2017 for reasons that have not been elucidated by Bitmain CEO (and cofounder Jihan Wu).

Antpool claims that it will only signal for Segwit if there is a hardfork, which is a proposition that most users oppose. Furthermore, allegations that the owner refuses to sell hardware to Segwit supporters have also begun to circulate.

By using Antpool, you allow the pool to decide your hardware’s approach to these matters, meaning that the pool that you used dictates the type of Bitcoin protocol that your hardware employs. If you wish to decide which implementation your hardware should signal for, you can use a pool that leaves the choice to its users, like the Slush mining pool.

Bitfury Information

According to BlockTrail, Bitfury is the third largest Bitcoin mining pool and mines about 11% of all blocks.

The main difference between the Bitfury pool and other mining pools is that Bitfury is a private pool.

Bitfury, the company, makes its own mining hardware and runs its own pool. So, unlike Slush or Antpool, Bitfury cannot be joined if you run mining hardware at home.

Bitfury 16nm ASIC Chip

Unrelated to its pool, Bitfury sells a 16nm ASIC mining chip.

Although Bitfury controls a large portion of the Bitcoin network hash rate, its committed to making Bitcoin decentralized :

BitFury is fundamentally committed to being a responsible player in the Bitcoin community and we want to work with all integrated partners and resellers to make our unique technology widely available ensuring that the network remains decentralized and we move into the exahash era together.

Valery Vavilov, CEO of BitFury

BTCC Mining Pool Review

BTCC Mining Pool is run by BTCC, a Bitcoin company based in China. The company also runs a Bitcoin exchange, wallet, prints physical bitcoins and more!

Worldwide Servers

BTCC runs servers all over the world so your mining hardware can connect easily to the BTCC pool.

So even though BTCC is based in China, don’t be worried that you can’t use or join the pool:

Our mining pool currently has customers from the United States, South America, Europe, China, and Africa.

Bobby Lee, BTCC CEO

Shared Transaction Fees

One great thing about BTCC pool is that it shares Bitcoin transaction fees with its miners.

In every Bitcoin block, around 1-2 BTC worth of transaction fees are also rewarded to the pool.

Some pools keep these fees for themselves and DO NOT share with their miners! BTCC evenly splits the transaction fees among its miners, just like it splits the 12.5 BTC reward.

Slush Pool Review

Slush Pool is run by Satoshi Labs and was the world’s first ever Bitcoin mining pool. It’s advanced yet also a great pool for beginners.

How to Join and Use Slush Pool

Slush Pool is easy to join.

• First, register an account.
• Configure your mining software to point your hardware’s hash power to Slush Pool.
• Enter your Bitcoin wallet address that will receive the payouts.

Here is a helpful video that shows you how to get started:

Slush Mining Pool URLs

According to Slush’s website, there are the current URLs for the mining pool. You will want to point your software towards the URL location closest to you. This will maximize your mining profits.

USA, east coast:

Europe

China, mainland

Asia-Pacific/Singapore:

What are Slush Pool’s Fees?

Slush Pool charges 2% of all payouts.

This may seem like a lot but unlike other pools it shares the transaction fees with its miners. At current levels, these amount to 1-2 BTC more per block.

Satoshi Labs

Satoshi Labs runs Slush Pool. They also make the Bitcoin TREZOR hardware wallet and Coinmap.org.

Ethereum Mining Pool

Many people want to use the pools above for Ethereum too. But, most of the pools listed above are only for Bitcoin mining. Please see our post on Ethereum mining pools for more info on ETH specific pools.

Litecoin Mining Pool

Like Ethereum, none of the pools above support litecoin. For LTC mining you will need separate hardware and a separate pool.

Bitcoin Mining Pool Taxes

You’ll have to consult an accountant or lawyer in your area. But most likely you will have to pay income tax on income from mining pools just like you would for any other type of income.

Welcome to the first Minecraft server denominated in cryptocurrency

The currency on this server are the Bits. A bit is a fraction of a Bitcoin (1/1000000) that you can obtain by killing monsters, trading with users or transfering from an outside wallet. All of it is stored on a standard Bitcoin wallet on the Blockchain.

Level System

The level system is different that in a vanilla server. You gather experience from killing mobs and is never lost. Your XP allows you to become stronger and gain extra health.

BitQuest is made having the concept of fun in it. Bots and AFK farming are strictly banned.

How Bitcoin Mining Works

Where do bitcoins come from? With paper money, a government decides when to print and distribute money. Bitcoin doesn't have a central government.

With Bitcoin, miners use special software to solve math problems and are issued a certain number of bitcoins in exchange. This provides a smart way to issue the currency and also creates an incentive for more people to mine.

Bitcoin is Secure

Bitcoin miners help keep the Bitcoin network secure by approving transactions. Mining is an important and integral part of Bitcoin that ensures fairness while keeping the Bitcoin network stable, safe and secure.

Bitcoin mining is the process of adding transaction records to Bitcoin's public ledger of past transactions or blockchain. This ledger of past transactions is called the block chain as it is a chain of blocks. The block chain serves to confirm transactions to the rest of the network as having taken place.

Bitcoin nodes use the block chain to distinguish legitimate Bitcoin transactions from attempts to re-spend coins that have already been spent elsewhere.

What is Bitcoin Mining?

What is the Blockchain?

Bitcoin mining is intentionally designed to be resource-intensive and difficult so that the number of blocks found each day by miners remains steady. Individual blocks must contain a proof of work to be considered valid. This proof of work is verified by other Bitcoin nodes each time they receive a block. Bitcoin uses the hashcash proof-of-work function.

The primary purpose of mining is to allow Bitcoin nodes to reach a secure, tamper-resistant consensus. Mining is also the mechanism used to introduce Bitcoins into the system: Miners are paid any transaction fees as well as a "subsidy" of newly created coins.

This both serves the purpose of disseminating new coins in a decentralized manner as well as motivating people to provide security for the system.

Bitcoin mining is so called because it resembles the mining of other commodities: it requires exertion and it slowly makes new currency available at a rate that resembles the rate at which commodities like gold are mined from the ground.

What is Proof of Work?

A proof of work is a piece of data which was difficult (costly, time-consuming) to produce so as to satisfy certain requirements. It must be trivial to check whether data satisfies said requirements.

Producing a proof of work can be a random process with low probability, so that a lot of trial and error is required on average before a valid proof of work is generated. Bitcoin uses the Hashcash proof of work.

What is Bitcoin Mining Difficulty?

The Computationally-Difficult Problem

Bitcoin mining a block is difficult because the SHA-256 hash of a block's header must be lower than or equal to the target in order for the block to be accepted by the network.

This problem can be simplified for explanation purposes: The hash of a block must start with a certain number of zeros. The probability of calculating a hash that starts with many zeros is very low, therefore many attempts must be made. In order to generate a new hash each round, a nonce is incremented. See Proof of work for more information.

The Bitcoin Network Difficulty Metric

The Bitcoin mining network difficulty is the measure of how difficult it is to find a new block compared to the easiest it can ever be. It is recalculated every 2016 blocks to a value such that the previous 2016 blocks would have been generated in exactly two weeks had everyone been mining at this difficulty. This will yield, on average, one block every ten minutes.

As more miners join, the rate of block creation will go up. As the rate of block generation goes up, the difficulty rises to compensate which will push the rate of block creation back down. Any blocks released by malicious miners that do not meet the required difficulty target will simply be rejected by everyone on the network and thus will be worthless.

The Block Reward

When a block is discovered, the discoverer may award themselves a certain number of bitcoins, which is agreed-upon by everyone in the network. Currently this bounty is 25 bitcoins; this value will halve every 210,000 blocks. See Controlled Currency Supply.

Additionally, the miner is awarded the fees paid by users sending transactions. The fee is an incentive for the miner to include the transaction in their block. In the future, as the number of new bitcoins miners are allowed to create in each block dwindles, the fees will make up a much more important percentage of mining income.

Bitcoin mining server

I have a vps, it's debian but i can install any os, i don't use it a lot, can i use it to mine bitcoins? Correct me if I'm wrong, bitcoins uses video cards, and as far as i know, vps and dedicated servers don't have video cards.

So therefore I'm asking, is it possible to use servers to mine bitcoins

It is possible, but not profitable. Even if you consider the server as already paid for you will not generate nearly enough of a hashrate to earn more than a few cents a month.

A long time ago I read about using amazon cloud instances when the value vs. effort made it profitable to mine with them, but that was before GPU-mining took over.

To be competitive today a service provider would have to employ ASICs. There would also be some economical overhead of providing the customer service, instead of just mining. Strict bitcoin mining operations like for example ASICminer have an advantage over that.

Mining Bitcoin is possible, but almost certainly not profitable if it's the sole purpose of the VPS. You may, however, find profitability in other altcoins, such as Litecoin or Bytecoin.

I rented a VPS to do data analysis on the blockchain, so I ran a bitcoin client, which can have a heavy disk IO, and bitcoin-abe, which is similarly heavy due to a database backend. I loaded both bitcoind and mysql through libeatmydata to lessen the load (less syncs). I wasn't mining. Within a couple of hours, the provider suspended my account due to "bitcoin mining". I complained but they never unsuspended me.

The main issue with CPU mining is that before you manage to finish a share the block becomes stale - you barely get anything out as far as I can tell.
