USB Bitcoin Miners

USB Bitcoin miners are available to buy, but they don’t really generate any significant profits.

They’re a good choice if you just want to fool around with Bitcoin mining and miners like the Antminer S9, S7, S5, Antminer R4, SP20, and Avalon6 are too expensive for you.

You should buy one to learn how mining works, but other than that don’t expect much! If you are serious about making profit then check out better Bitcoin mining hardware.

You can always check the profitability of a USB miner using our mining calculator.

Don’t Get Confused

There is USB Bitcoin mining hardware, which mines bitcoins.

There are also Bitcoin hardware wallets like the Ledger Nano S, which store bitcoins.

Both are USB type devices that have completely separate functions!

Bitcoin USB Miners Comparison

ASICMiner Block Erupter USB 330MH/s Sapphire Miner

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

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

GekkoScience Compac USB Stick Bitcoin Miner

The GekkoScience miners is just slightly better than the original block erupters.

It will net you about $0.15 per month, which is more than a dollar per year! The company claims that the device runs completely silent. It works with just one USB port.

Avalon Nano 3

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

Bitmain Antrouter R1 Wifi Solo Bitcoin Miner

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

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

21 Bitcoin Computer

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

But since it’s still technically a USB miner we have included it in this list.

If you’re not impressed, we don’t blame you! USB Bitcoin mining was only profitable when Bitcoin was in its early years. If you just want bitcoins then invest in serious mining hardware or just buy bitcoins.

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 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.

How to use a USB Bitcoin Miner?

This is a guide on how to mine bitcoins using the USB Block Erupters that we have for sale.

STEP 1: Join a Pool

By joining a mining pool you are working together with other miners and sharing the Bitcoin rewards. This means you get a more steady flow of small bitcoin payments. It is a good idea to join several pools that way if one pool goes offline you can simply switch to another.

We recommend using Bitminter pool: http://bitminter.com/

You can join any pool that you want, but for this example we will assume that you have registered for the Bitminer pool above.

STEP 2: Download CGMiner

Unzip the content to your computer, for example unzip to “C:\cgminer-3.1.0-windows\”

** If you are using a Bitmain Antminer U1, then install BFGminer instead: READ GUIDE **

STEP 3: Download and install this driver

STEP 4: Connect your USB Miner(s)

Insert your USB miner into a USB port on your computer. Or You could plug it into a USB hub connected to your computer, but you must make sure it is a powered USB hub, as each miner requires 2.5WA of power.

STEP 5: Note down the COM Numbers for each Device.

• In Windows 7, go to Control Panel
• Click on Printers and Devices
• You should see USB devices similar to what is shown below:

Note the “COM3”, “COM4” etc…

STEP 6: Create a Desktop Shortcut.

Right click on your desktop and choose New -> Shortcut; use the browse option to locate the cgminer-fpgaonly.exe file that you unzipped earlier.

Then right click on the new shortcut and click “Properties”. In the “Target:” update to show as follows:

C:\cgminer-3.1.0-windows\cgminer-fpgaonly.exe -o [pool]:[port] -u [username].[worker] -p [password] --icarus-options 115200:1:1 --icarus-timing 3.0=100 -S //./COM3 -S //./COM4 -S //./COM5 -S //./COM6

Notice that pool, port, username, worker and password are private credentials you provide for your pool worker.

If you are using the Bitminer pool mentioned above, your worked will be “1” and your password will be “x”, here is an example of using the Bitminer pool:

C:\cgminer-3.1.0-windows\cgminer-fpgaonly.exe -o mint.bitminter.net:3333 -u bitcoinco_1 -p x --icarus-options 115200:1:1 --icarus-timing 3.0=100 -S //./COM3 -S //./COM4 -S //./COM5 -S //./COM6

In this example the USBs have COM numbers of COM3, COM4, COM5, COM6 . Yours will be different depending on what is reported in your Device Manager. You would need as many of these in your target line as you have miners.

STEP 7: Launch CGMiner

Double click on the desktop shortcut that you created and you will start mining, you should see a screen looking like this:

Leave this window open in the background at all times to continue mining.

Transcript - USB - Bitcoin Mining Setup Guide

What’s going on every one? This is Fred and today we’re going to build a Bitcoin miner. All right. So, if you’re unfamiliar with Bitcoin I do have another video that has all the 10 things that you need to know about Bitcoin. So, give that a watch, get caught up, come back and we’ll get started.

So, here’s all the pieces that you need to start building your own Bitcoin miner. I will place some links to all the parts down below so that you can get started on your project. Now, the first item that you want to pick up is called a Raspberry Pi. Now, this is basically just a credit card sized computer. Now, the nice thing about having one of these is that this is a completely separate unit from your personal computer, which means you can mine for Bitcoins 24x7 without affecting your daily computer usage. Now, when you’re picking up one of these you want to make sure that you get the version B. Now, due to its size it’s very efficient on power consumption. This entire computer can be powered by USB cable.

The next item on the list is just a plastic case for your Raspberry Pi. Now this is an optional item but I highly recommend it because it will protect your Raspberry Pi in case anything falls on top of it. Plus, it’s very inexpensive. This one was about $10. Okay. So, you’ll also have to get an SD card. Now this SD card basically acts as the hard drive for your Raspberry Pi. Now you want to get a 4 gigabyte minimum on this card. Now I have an 8 gigabyte just because it was on sale and easier to find at the time. The thing that you want to focus on is getting a class 10 SD class. And to power your Raspberry Pi you will need a micro USB to USB cable. So, all the parts that I just listed basically creates a separate computer. Now this computer will run the mining software. All the parts that I list next will be the actual mining hardware that will mine for Bitcoins.

Okay, so this is the actual hardware that mines for Bitcoins. This is called an ASIC miner or a Block Erupter. Now this is basically just a chip that has one job and that is to mine for Bitcoins. It could be powered by USB so you could plug a bunch of these into a USB port. Now this specific one mines at a rate of 335 megahashes per second. So, what I have is I have six of them so these will give me over 2 gigahashes of mining power. Okay. And to power all those Block Erupters you need to get a good quality powered USB hub. Now the keyword here is powered meaning that there is an eternal adapter that you plug into the wall outlet.

Now this will give it an even power across all of the USB ports. Now you don’t want to cheap out on this you definitely want to get a good quality hub. Now because your Bitcoin miner will be running 24x7, those Block Erupters tend to get pretty warm. Now what you can do is just get one of these USB fans, plug it into the USB port and this is a very good inexpensive way to keep things cool. Okay. Lastly, all you need is an Ethernet cable. Now this is what’s going to get your Bitcoin miner connected to the internet. Okay, so that’s all the hardware that you will need for this project. Let’s start putting everything together starting with the Raspberry Pi.

Okay, so the first thing you do is take apart the case and place your Raspberry Pi on the bottom piece. Now just go ahead and line everything up and it should snap together, like so. Then just go ahead and put the cover over just like that. Okay, so as you can see your Raspberry Pi will have two USB ports. A spot for your Ethernet connection it’s going to have some audio and video outputs. This slot is for the SD card. Here is a micro USB to power the unit. And then finally you’ll also have an HDMI output so that you could connect this to a screen.

The next step is to insert your SD card into your Raspberry Pi. Now this SD card is already loaded with my mining software. Right now I’m using an operating system called MinePeon. Now if you’re not familiar with how to load up the software onto your SD card, I will be making another video going through the step by step instructions on how to do that. But until then just take your Raspberry Pi and insert the card into its SD slot, like so. Okay, now let’s take a look at the USB hub. Now this is not plugged in yet. I just want to get everything installed prior to powering it up. The first thing that I’m going to do is install the power cord for the Raspberry Pi. I’m going to put it in the first slot right here and then move this off to the side for later use.

Next I’m going to start plugging in the Block Erupters one by one. I have a total of six. Make sure they’re in there nice and firm evenly seeded. Like I mentioned before, each one of these Block Erupters are able to mine at roughly 335 megahashes per second. So with six of them I am getting roughly 2 gigahashes. All right, so I have six of them plugged in right here. And finally take your USB fan and just direct it above the Block Erupters. Now this USB hub has a USB 2.0 connection right here on the end. Now this is going to connect to the USB ports on the Raspberry Pi. So the Raspberry Pi has two USB ports we are just going to need one of them, like so.

Next, take your Ethernet cable, connect it to the Ethernet spot on your Raspberry Pi and connect the other end to your modem. Once you have everything plugged in just go ahead and power it up. Okay, so as you can see by these green LED indicators it’s just telling you that these Block Erupters are properly installed or in standby. All you need to do now is go into your mining software, set up your mining pools and start mining. It’s just easy as that guys.

All right, so that’s all the hardware that you will need to start mining for Bitcoins. Now this mining rig is mining at over two gigahashes, which is not too bad considering the costs and simplicity of the entire project. Now I’m going to show you a quick screen shot of the performance that I am getting with this mining rig using the MinePeon software. Now if you need help setting up the mining software I will be uploading another video soon showing you the step by step instructions of how to get everything set up. But this video should give you a good head start. Start ordering the parts that you need and I will see you on the next video, but until then have fun mining guys.

What Is a USB Bitcoin Miner? How Does It Work?

• Governance: Why Crypto Investors Should Care
• Blockchain-as-a-Service (BaaS)
• Which FAANG Will Win the Blockchain Wars?

Bitcoins can be earned by purchasing them using dollars or other currencies, by selling goods or services and receiving payments via bitcoins, or by bitcoin mining. The bitcoin mining process involves verification of transactions and their addition to the blockchain through which new bitcoins are released.

Bitcoin mining is performed using dedicated electronic devices called miners that have high computing capacity. As cryptocurrency mania spreads around the world, USB-powered mining devices are becoming popular for their ease of use, seamless connectivity, and lower power consumption. We explain how a USB-based bitcoin miner works. (For more, see How Does Bitcoin Mining Work?)

Historical Developments

The rapidly evolving technology has made bitcoin mining process a reality on home computers, though certain challenges - like excessive power consumption and limited profit potential - remain. Over the years, the mining process and efficiency have improved with the use of better hardware.

Bitcoin mining started with the standard Central Processing Unit (CPUs), an integral part of a standard computer. The mining efficiency was enhanced with the use of comparatively faster Graphic Processing Units (GPUs).

Then came the Field Programmable Gate Arrays (FPGAs), which scored better than both CPUs and GPUs at performing the hash calculations, an essential function to blockchain management in cryptocurrency.

FPGAs turned the concept of concentrated mining farms into reality, and were also the first kind of mining devices that supported USB connectivity. FPGAs are now superseded by the new-age Application Specific Integrated Circuits (ASICs), which consume less power and offer faster processing speeds compared to the former three.

How Do USB Bitcoin Miners Work?

Bitcoin mining is the only way to validate and release new cryptocurrency into circulation. Individuals or groups get incentives to participate in the system and validate the related transactions, which makes bitcoin mining an attractive activity.

A USB bitcoin miner, when connected to a computer with suitable software, performs the mining function at a certain speed of hashing. To enhance the hashing output, multiple miners can be plugged in together. For example, attaching six miners that offer 335 megahashes per second (MH/s) can generate a cumulative 2 gigahashes of mining power.

Since a standard computer usually has only 2 to 4 USB ports, a USB hub is used to plug in the multiple USB miners. The USB hub assembly is then connected to a computer that is installed with a software capable of controlling the USB miners and their mining operations. The software also facilitates real-time monitoring of the performance of USB miners. The commonly used software include MacMiner, Asteroid, MinePeon, and BFGMiner. (For more, see Popular Bitcoin Mining Software.)

Instead of connecting to a standard PC or laptop, the USB bitcoin miner setup can be connected to other smaller, low-cost computer devices like Raspberry Pi, which offers suitable capacity to run the miners.

The Bottom Line

With lower setup costs, USB miners offer an easy and fun way to learn about the nuances of cryptocurrency mining. However, there are concerns about the possibility of reaping profits, as high power consumption still dents a blow to achieving net profits from the operation.

In the search for Anaïs Nin, one of the first few links shows a picture of a man. Why? Since Nin is a woman, I can’t figure out why. Can you show some reason for this? Who is he? If you click on the picture a group of pictures of Nin and no mention of that man. Is it an error?

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
www.att.com.

WEBPAGE NOT AVAILABLE

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.

Transcript - USB - Bitcoin Mining Setup Guide

What’s going on every one? This is Fred and today we’re going to build a Bitcoin miner. All right. So, if you’re unfamiliar with Bitcoin I do have another video that has all the 10 things that you need to know about Bitcoin. So, give that a watch, get caught up, come back and we’ll get started.

So, here’s all the pieces that you need to start building your own Bitcoin miner. I will place some links to all the parts down below so that you can get started on your project. Now, the first item that you want to pick up is called a Raspberry Pi. Now, this is basically just a credit card sized computer. Now, the nice thing about having one of these is that this is a completely separate unit from your personal computer, which means you can mine for Bitcoins 24x7 without affecting your daily computer usage. Now, when you’re picking up one of these you want to make sure that you get the version B. Now, due to its size it’s very efficient on power consumption. This entire computer can be powered by USB cable.

The next item on the list is just a plastic case for your Raspberry Pi. Now this is an optional item but I highly recommend it because it will protect your Raspberry Pi in case anything falls on top of it. Plus, it’s very inexpensive. This one was about $10. Okay. So, you’ll also have to get an SD card. Now this SD card basically acts as the hard drive for your Raspberry Pi. Now you want to get a 4 gigabyte minimum on this card. Now I have an 8 gigabyte just because it was on sale and easier to find at the time. The thing that you want to focus on is getting a class 10 SD class. And to power your Raspberry Pi you will need a micro USB to USB cable. So, all the parts that I just listed basically creates a separate computer. Now this computer will run the mining software. All the parts that I list next will be the actual mining hardware that will mine for Bitcoins.

Okay, so this is the actual hardware that mines for Bitcoins. This is called an ASIC miner or a Block Erupter. Now this is basically just a chip that has one job and that is to mine for Bitcoins. It could be powered by USB so you could plug a bunch of these into a USB port. Now this specific one mines at a rate of 335 megahashes per second. So, what I have is I have six of them so these will give me over 2 gigahashes of mining power. Okay. And to power all those Block Erupters you need to get a good quality powered USB hub. Now the keyword here is powered meaning that there is an eternal adapter that you plug into the wall outlet.

Now this will give it an even power across all of the USB ports. Now you don’t want to cheap out on this you definitely want to get a good quality hub. Now because your Bitcoin miner will be running 24x7, those Block Erupters tend to get pretty warm. Now what you can do is just get one of these USB fans, plug it into the USB port and this is a very good inexpensive way to keep things cool. Okay. Lastly, all you need is an Ethernet cable. Now this is what’s going to get your Bitcoin miner connected to the internet. Okay, so that’s all the hardware that you will need for this project. Let’s start putting everything together starting with the Raspberry Pi.

Okay, so the first thing you do is take apart the case and place your Raspberry Pi on the bottom piece. Now just go ahead and line everything up and it should snap together, like so. Then just go ahead and put the cover over just like that. Okay, so as you can see your Raspberry Pi will have two USB ports. A spot for your Ethernet connection it’s going to have some audio and video outputs. This slot is for the SD card. Here is a micro USB to power the unit. And then finally you’ll also have an HDMI output so that you could connect this to a screen.

The next step is to insert your SD card into your Raspberry Pi. Now this SD card is already loaded with my mining software. Right now I’m using an operating system called MinePeon. Now if you’re not familiar with how to load up the software onto your SD card, I will be making another video going through the step by step instructions on how to do that. But until then just take your Raspberry Pi and insert the card into its SD slot, like so. Okay, now let’s take a look at the USB hub. Now this is not plugged in yet. I just want to get everything installed prior to powering it up. The first thing that I’m going to do is install the power cord for the Raspberry Pi. I’m going to put it in the first slot right here and then move this off to the side for later use.

Next I’m going to start plugging in the Block Erupters one by one. I have a total of six. Make sure they’re in there nice and firm evenly seeded. Like I mentioned before, each one of these Block Erupters are able to mine at roughly 335 megahashes per second. So with six of them I am getting roughly 2 gigahashes. All right, so I have six of them plugged in right here. And finally take your USB fan and just direct it above the Block Erupters. Now this USB hub has a USB 2.0 connection right here on the end. Now this is going to connect to the USB ports on the Raspberry Pi. So the Raspberry Pi has two USB ports we are just going to need one of them, like so.

Next, take your Ethernet cable, connect it to the Ethernet spot on your Raspberry Pi and connect the other end to your modem. Once you have everything plugged in just go ahead and power it up. Okay, so as you can see by these green LED indicators it’s just telling you that these Block Erupters are properly installed or in standby. All you need to do now is go into your mining software, set up your mining pools and start mining. It’s just easy as that guys.

All right, so that’s all the hardware that you will need to start mining for Bitcoins. Now this mining rig is mining at over two gigahashes, which is not too bad considering the costs and simplicity of the entire project. Now I’m going to show you a quick screen shot of the performance that I am getting with this mining rig using the MinePeon software. Now if you need help setting up the mining software I will be uploading another video soon showing you the step by step instructions of how to get everything set up. But this video should give you a good head start. Start ordering the parts that you need and I will see you on the next video, but until then have fun mining guys.

USB Bitcoin Miner

How to Get Started as a USB Bitcoin Miner

Getting into the world of bitcoin is exciting, but can also be a little confusing. Read on to learn about bitcoin and how to get started as a USB bitcoin miner.

Keyword(s): usb bitcoin miner

Do you think you have what it takes to become a bitcoin miner? Are you looking at buying a USB Bitcoin Miner?

Maybe you’re drawn to some of the things you’ve heard about Bitcoin-- how it may be the currency of the future. Maybe you’ve heard of how versatile and simple it is to use and exchange.

We live in an age where you can take out your smartphone and send 10 different amounts of Bitcoin to 10 different people, in 10 different countries, in less than 10 minutes.

And you can do it from your smartphone, in your pajamas with a cup of tea.

If you wanted to do the same thing with traditional currency, it would take you a day just to work with all the banks involved to confirm and transfer the amount.

Plus convert to their own local currency. And then the money would be in escrow for a few days. But again, with Bitcoin: 10 minutes, smartphone, pajamas, tea.

It’s done! How is this possible? Behind the hard work and digital heavy lifting of bitcoin miners. Want to become one? Here’s how:

What is a Bitcoin Miner?

The term “miner” actually is very accurate and fitting. In the old, old days before we started to print money, jewels and medals were the currency we exchanged.

Miners would be the ones going into the mines and unearthing these precious stones and metals so they could be put into the economy. And for their trouble, these miners would often get rewarded with a bit of currency themselves.

That’s pretty much the model of the Bitcoin miner. Only, they’re not using a pickaxe, they’re using a specialized software, or hardware like a USB Bitcoin Miner.

They go out on the web and solve incredibly complex math problems to mine the Bitcoin currency, and when they succeed, they’re rewarded with Bitcoin payments for their hard work.

Now, they also earn money another way: by monitoring and approving Bitcoin transactions. They approve or deny a transaction, with an eye out for fraudulent deals.

And if the deal is approved, they get a piece of the action for their effort. Adding more Bitcoin miners will mean a more secure network for the world.

It also means faster transactions, with more Bitcoin miners hard at work to push these transactions through the world’s digital economy.

The Challenge of the Bitcoin Miner

As we just mentioned, more Bitcoin miners mean the currency is faster and safer. But that also means it’s a whole lot harder to mine. Hence the need for a USB Bitcoin Miner.

Like gold or diamonds, there is a limited amount of it out there. So, the more you find, the less is left, and the more the value will rise as you get to the end of your undiscovered supply. Make sense? So let’s look at it this way:

• There are 21 million Bitcoins available in the world
• Right now, we’ve mined about 72% of all bitcoins, and they are already in circulation
• By comparison, as of 2013, there was over $1.2 trillion of US currency in circulation.
• Right now, one Bitcoin is worth almost $1,000.00 USD.
• In 2009, 1 Bitcoin was worth 0.0001 USD
• To put the rising demand and value into perspective, in 2013 it was reported that a Norwegian man bought $27 worth of bitcoins in 2009. He then forgot about them completely before he discovered their value had ballooned to $980,000.

Can you imagine?

The plight and methods of the Bitcoin miner have changed over the years. The faster demand to mine, and mine, and mine has driven the need for faster and more specialized equipment.

We will touch on that a bit later. Now, the successful Bitcoin miner no longer works alone on their laptop. They work in teams, or what’s called “Bitcoin pools.”

It’s exactly what it sounds like. A team of skilled and like-minded Bitcoin miners getting together to pool brains, tools, and resources.

And each member of the team will get a percentage of the Bitcoins that pool has worked so hard to mine, based on the relative amount of work he or she has done.

The Tools of the Bitcoin Farmer: the USB Bitcoin Miner

To succeed in this business, you’re going to need a combination of the right hardware and software.

In the beginning, the miners simply used their computer’s central processing unit (CPU) to do the work. Why wouldn’t they? It was all they had and all anyone had ever used.

That was until a few years later when a few savvy miners saw the inherent value in using a video game graphic card. Graphics cards were able to process a miner’s work 50 to 100 times faster and consumed much less power per unit of work.

Graphics cards were able to process a miner’s work 50 to 100 times faster and consumed much less power per unit of work. Fast forward to the winter of 2011.

Fast forward to the winter of 2011. The next big thing in Bitcoin mining was the USB Bitcoin Miner and field-programmable gate array (FPGA) processors that could now hook into your computer via the USB port.

These were faster than anything we had seen so far and opened the doors to concentrated mining farms. The USB Bitcoin Miner changed everything.

Now hit skip to the next chapter, titled “Application-specific integrated circuit (ASIC) miners.” To call these a game-changer is a bit of an understatement.

They were ungodly fast compared to everything else out there and consumed far less power.

This is the standard where everyone is at now. ASIC miners are the most commonly used tool and some popular models include:

ASIC miners are the most commonly used tool and some popular models 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.

Again, only about 28% of the world’s Bitcoins remain unmined. So the competition is getting more heated among miners. That means technology is getting faster and much more expensive, as the bar and demand keep going up, and up, and up.

The Tools of the Bitcoin Farmer - Software

The first thing you will need (duh) is a place to keep your currency, which is called a Bitcoin wallet. There are a number of them out on the market for you to choose from, like:

• Breadwallet
• Copay
• Armory
• Coinbase
• Circle

These tools can help you generate a Bitcoin address, which is what you will need to work in a Bitcoin miner pool. The next thing you will need is your Bitcoin mining software:

• MinePeon
• EasyMiner
• BFGMiner
• CGMiner

There are also some really good free Bitcoin mining applications out there, such as:

• MinePeon
• EasyMiner
• BFGMiner
• CGMiner
• 50Miner
• BTCMiner
• BitMoose
• Poclbm
• Poclbm-mod
• DiabloMiner
• RPC Miner
• Phoenix miner
• CPU Miner
• Ufasoft Miner
• Pyminer
• Remote Miner
• Open Source FPGA Bitcoin Miner

How to Find and Join a Bitcoin Miner Pool

You don’t want to do this alone. Trust us. The days of the solo miner are long gone. Now, if you really want to make money, you have to join a reliable and stable pool. Some of your options out there include:

• BTCC
• Antpool
• Slushpool
• Bitmain
• Eligius
• BitMinter
• Kano CKPool
• F2Pool
• BW Pool
• Bitfury
• p2pool

How Do I Choose a Bitcoin Pool?

First of all, you’re going to want to see what language your given pool works in. For example, F2Pool and BW Pool’s user interface is in Chinese, so it’s not much good to people who only speak English.

The next thing you’ll want to think about is how is the money shared? Now there are lots of different methods and philosophies out there for how to distribute the spoils fairly in a Bitcoin miner pool. They include:

• The Pay-per-Share (PPS)
• The Pay Per Last N Shares (PPLN)
• The Double Geometric Method (DGM)
• The Shared Maximum Pay Per Share (SMPPS)
• The Equalized Shared Maximum Pay Per Share (ESMPPS)
• The Recent Shared Maximum Pay Per Share (RSMPPS)
• The Capped Pay Per Share (CPPSRB)
• Bitcoin Pooled mining (BPM)
• The Pay on Target (POT)
• SCORE
• ELIGIUS
• Triplemining

Predictions For Bitcoin Miners

As we’ve said the value of bitcoin is only going to increase as the supply grows more scarce and the world adds more and more bitcoin miners to the network.

In fact, there is speculation that the value of Bitcoin could jump even higher, thanks to US President Donald Trump.

“We could see bitcoin easily triple over the next year going from the current level to $2,100,” said chief economist at Saxo Bank, Steen Jakobsen.

We’ve already seen the Bitcoin be worth $400.00 US at the start of 2016, and jumped to $600.00 to start 2017.

Other experts agree and Benoit Tessier of Reuters wrote that “the price of bitcoin will continue to rise as more devaluations are expected from the Chinese government.”

“The slower appreciation of the US dollar against the Chinese yuan in comparison to bitcoin against the greenback shows that Saxo Bank’s $2,000 forecast is not unrealistic.”

So now would definitely be the time to get on board, if you’re even considering becoming a Bitcoin miner. This is like getting on the ground floor… of money.

Imagine you were the guy we mentioned earlier who turned 27 Bitcoins into $900,000. Of course, you can’t just buy it and forget about it like he did. You have to work for it these days.

And if you’re looking at joining the faction of smart and hardworking people who are (quite literally) building the economy of the future, we can help.

How to determine the best USB Bitcoin Miner that suits your needs and wants?

It really depends on your goal and purpose. So you should ask yourself if buying this miner answers the question of need and want.

What are the goals?

If you are aiming for profit and money, then don't buy one. You can't find anywhere in the world that is a profitable USB miners. But it doesn't mean that for those right person it doesn't make excellent gifts also.

What kind do you want?

Are you looking for a stick miner, which is similar to a flash drive, or maybe a larger one that will just connect to a USB and have its own power supply?

By looking at the stores online, you can see different options that also varies with a variety of price and versatility. If you want to gift someone that ages like a teenager and interested with the technology, then what you are looking for is ASICMiner Block Erupter.

21 Inc. Bitcoin Computer have price costs as much as a low-end tablet computer. Their differences isn't just in their relative mining power but also in what they can do.

The ASICMiner will just be utilizing your computer software running in order to mine bitcoin, on the other hand, 21 Inc. Bitcoin Computer is standalone and it can mine of its own and does a number of other things.

What is your budget for USB Bitcoin Miner?

Market these days have couple of nice and well-priced USB stick miners. GekkoScience Compac is one of the option which produced independently and unfortunately in a very small print run.

The original price range might be differ up to $25 per unit by the time you read this. It means that options in the market are really great. They’re able to produce at least 8 GH/s (gigahashes per second), and up to 11 GH/s, which is incredible for a USB stick.

You can calculate what that will produce in terms of Bitcoin using this Bitcoin Mining Calculator. At current, it produces about $0.50 per month. Not exactly a lot–but as I said at the beginning, these are for hobby purposes, not profit.

Another good option is Avalon 3 Nano, if the above options aren't available. You can just have it for like over $25 and it was released in early 2015.

It will generate a consistent 3 GH/s, and is at a better price range for most purposes. However, the Avalon 3 Nano is a little harder to set-up, configure, and use.

If you just want to buy a device just to educate someone that has interest about Bitcoin, then you may decide you don't care about the hashing power of the device. For that option, you can have the ASICMiner Block Erupter. The price of these devices are available in less than $20 straight from Amazon as well as many online distributors that come with perfect, simple instructions and have lots of tech support available.

What about larger miners?

There are options also like Antminer R1 that will mine Bitcoin for you in the AntPool Solo Pool, which means it is attempting to win the proverbial Bitcoin lottery. You don't have this much luck to succeed, but it’s also just a fairly normal wireless router, and it’s priced competitively in that field.

Moreover, it’s just a kind of neat idea: a router that mines Bitcoin is just one possible device that can do that. What’s next, microwaves? Who knows.

There are a lot of choices and options you can find in buying USB Bitcoin Miner out there. But at the end of the day, it is you to decide what you need and what you want in order to succeed on your goals.

How to use a USB Bitcoin Miner?

This is a guide on how to mine bitcoins using the USB Block Erupters that we have for sale.

STEP 1: Join a Pool

By joining a mining pool you are working together with other miners and sharing the Bitcoin rewards. This means you get a more steady flow of small bitcoin payments. It is a good idea to join several pools that way if one pool goes offline you can simply switch to another.

We recommend using Bitminter pool: http://bitminter.com/

You can join any pool that you want, but for this example we will assume that you have registered for the Bitminer pool above.

STEP 2: Download CGMiner

Unzip the content to your computer, for example unzip to “C:\cgminer-3.1.0-windows\”

** If you are using a Bitmain Antminer U1, then install BFGminer instead: READ GUIDE **

STEP 3: Download and install this driver

STEP 4: Connect your USB Miner(s)

Insert your USB miner into a USB port on your computer. Or You could plug it into a USB hub connected to your computer, but you must make sure it is a powered USB hub, as each miner requires 2.5WA of power.

STEP 5: Note down the COM Numbers for each Device.

• In Windows 7, go to Control Panel
• Click on Printers and Devices
• You should see USB devices similar to what is shown below:

Note the “COM3”, “COM4” etc…

STEP 6: Create a Desktop Shortcut.

Right click on your desktop and choose New -> Shortcut; use the browse option to locate the cgminer-fpgaonly.exe file that you unzipped earlier.

Then right click on the new shortcut and click “Properties”. In the “Target:” update to show as follows:

C:\cgminer-3.1.0-windows\cgminer-fpgaonly.exe -o [pool]:[port] -u [username].[worker] -p [password] --icarus-options 115200:1:1 --icarus-timing 3.0=100 -S //./COM3 -S //./COM4 -S //./COM5 -S //./COM6

Notice that pool, port, username, worker and password are private credentials you provide for your pool worker.

If you are using the Bitminer pool mentioned above, your worked will be “1” and your password will be “x”, here is an example of using the Bitminer pool:

C:\cgminer-3.1.0-windows\cgminer-fpgaonly.exe -o mint.bitminter.net:3333 -u bitcoinco_1 -p x --icarus-options 115200:1:1 --icarus-timing 3.0=100 -S //./COM3 -S //./COM4 -S //./COM5 -S //./COM6

In this example the USBs have COM numbers of COM3, COM4, COM5, COM6 . Yours will be different depending on what is reported in your Device Manager. You would need as many of these in your target line as you have miners.

STEP 7: Launch CGMiner

Double click on the desktop shortcut that you created and you will start mining, you should see a screen looking like this:

Leave this window open in the background at all times to continue mining.
