Top 5 USB Bitcoin Miners: Best Legit ASIC Mining Hashing Devices?
Advances in the world of cryptocurrency mining have been made in the form of USC bitcoin miners, which are now available for purchase. However, they are not necessarily a game-changer for serious miners. USB bitcoin miners are geared more toward novices who want to learn more about mining and just do some hashing experimenting with it.
Top 5 USB Bitcoin Miners.
It's important not to get USC bitcoin miners confused with USC mining hardware or Bitcoin wallets that can help you to mine and store bitcoins. These are geared toward serious miners who are out to make a substantial profit. If you're just looking to get your feet wet and start learning more about Bitcoin mining, consider these five Bitcoin USB miners.
The 21 Bitcoin Computer barely fits into the category of USB Bitcoin miner. It's more so designed to build apps, services, and devices that can be utilized via Bitcoin. Its money to harsh ratio is unimpressive, so you may not find many Bitcoin experts lining up to recommend it. Nevertheless, it will connect to your computer via the USB port, so it's worth mentioning alongside other Bitcoin miners.
ASICMiner Block Erupted USB 330MH/s Sapphire Miner.
For a good learning experience, this may be your best option, as the Sapphire Block Erupters were among the first USB Bitcoin miners. However, with its hash power of 330 MH/s, it's not something you'll want to use if you're in it to make a profit.
The Nano 3 is relatively simple and easy to use. You can plug it into the USB port on your computer with no fan required. Of course, the hash power is right around 3.6 GS/s. In terms of Bitcoin mining, it's unlikely to net much more than $1 per year.
The Antrouter is another device that just barely fits into the category of USB Bitcoin miner. It doesn't provide much in terms of power, with just 5.5 GH/s, and so you shouldn't expect to make much more than $1 per year in profit. On the bright side, it's an inexpensive tool that can also serve as a wireless router, so it can also help to hook up all of your devices to the Internet.
GekkoScience Compact USB Stick Bitcoin Miner.
Among the USB Bitcoin miners for novice users, this may be the best option in terms of turning a profit by using hashing power from these devices (or use trading bots). With it, you can expect to make roughly 15 cents per month, which translates to almost $2 per year, nearly double some of the other devices we've mentioned.

What is Bitcoin Hashrate?
Bitcoin hashrate is a calculated numerical value that specifies an estimate of how many hashes are being generated by Bitcoin miners trying to solve the current Bitcoin block or any given block.
Bitcoin hashrate is represented in Hashes per Second or H/s.
The global Bitcoin network hashrate is a calculated value and is measured in hashes per second (H/s). The calculation uses the current mining difficulty and the average Bitcoin block time between mined blocks versus the defined block time as variables to determine the global Bitcoin network hashrate.
As the Bitcoin network hashrate goes up - the BTC hashrate numbers get so large that abbreviations must be used.
The abbreviations are SI derived units representing the number of hashes performed in a one second time frame.
The current Bitcoin hashrate is 144.13 EH/s, representing the global Bitcoin network hashrate with a mining difficulty of 17.60 T at block height 657,955.
Hashrate Unit/s Hash Hashes Per Second H /s (Hash) 1 One kH /s (KiloHash) 1,000 One Thousand MH /s (MegaHash) 1,000,000 One Million GH /s (GigaHash) 1,000,000,000 One Billion TH /s (TeraHash) 1,000,000,000,000 One Trillion PH /s (PetaHash) 1,000,000,000,000,000 One Quadrillion EH /s (ExaHash) 1,000,000,000,000,000,000 One Quintillion ZH /s (ZettaHash) 1,000,000,000,000,000,000,000 One Sextillion YH /s (YottaHash) 1,000,000,000,000,000,000,000,000 One Septillion.
It is important to point out the Bitcoin hashrate does not determine how quickly or slowly each block is solved.
This timing, called the block time is enforced by the Bitcoin mining difficulty value, which is adjusted upwards or downwards during each block difficulty retarget to keep blocks being solved at a constant time frame.
For more information about the Bitcoin difficulty re-target visit the Bitcoin mining page.
You can calculate Bitcoin mining profits using the current BTC hashrate difficulty and our Bitcoin mining calculator.
What is the Current Bitcoin Hashrate?
The current Bitcoin hashrate (BTC hashrate) is 144.13 EH/s at block height 657,955 with a difficulty of 17,596,801,059,571.43.

How to Calculate Bitcoin Hashrate.
The Bitcoin hashrate is calculated using the current Bitcoin difficulty , the defined Bitcoin block time , and the average block time of the last (X) number of blocks.
Most full Bitcoin nodes will have an option to see the current Bitcoin global hashrate using the "getnetworkhashps" command in the console window.
Given the fact that the Bitcoin difficulty value determines statically how many hashes are needed to solve the next block, it is recommended to use the current mining difficulty to determine the statistically accurate number of Bitcoin that can be mined in a given time frame.

What Is Solo Mining & How It Works?
Solo mining is a solo process where the miner completely does his task of mining operations without any helping hand. This process is mainly done alone without joining a pool. These blocks are mined and generated in a way to the task completed by the miner's credit.
Solo mining is the process of mining alone as we told earlier. We are aware that when you connect yourself to a pool, the process that mainly happens is that all miners get connected to the same bitcoin-client to confirm transactions. This helps to increase the probability of "finding" a block directly. Further, the block provides incentives from the shares from all miners.
If you do the process of solo mining, make sure to connect your miner to your local Bitcoin client. This is for getting the best results to "find" a block on your own. The probability will tend to decrease and lower, but in turn, you do not share the block incentive.
We all know how the Bitcoin network works. If your interest is to go for a long run solo mining and pooled mining you will get you exactly the same amount that you expected.
In this new digital world, the real option always goes with pooled mining because it is definitely the better way if you have the hardware which consists of small hash rate. The several tens of TH/s can be used to get more rewards from the solo mining than pooled mining.
The current hardware's utilized for the process of solo mining can deliver an experience which is more like playing the lottery. But if you do it right you can exit with a lot of cash.
What you need to solo mine - How it Works?
Firstly, install the Bitcoin-core which is hardware used for solo mining process. Henceforth, start it and complete the download of the blockchain which is almost 20 GB.
Afterward, create a bitcoin.conf file: C:\User\yourusername\AppData\Roaming\Bitcoin\
Finally, use 127.0.0.1:8332 as the server and the username and password you chose as the credentials to connect CGMiner or BFGMiner to the Bitcoin_Core client and have it mine.
Therefore, this is how the process of Solo Mining takes place to do mining as a solo task.
When Bitcoin launched in 2009, it became the world's first cryptocurrency. By utilizing miners that contribute their excess computation power to validate a movement of funds, it allows the network to remain decentralized.
As the value of Bitcoin has increased over time, more and more individuals are now taking the mining plunge. In fact, at the time of writing in mid-2018, there are now approximately 10,000 individual nodes, each hoping to get their slice of the highly lucrative Bitcoin mining space.
However, competition is now ultra-fierce, meaning that if you are thinking about solo mining Bitcoin - you should first read our guide. We'll start by explaining how the underlying Proof-of-Work mining algorithm works, followed by a discussion on why it is now becoming more difficult to mine on your own.
After that, if you still want to go ahead, we'll give you a comprehensive step-by-step guide on what you need to do to get started. Let's start by finding out just how Bitcoin mining works!
Essentially, mining allows transactions to be verified on a peer-to-peer basis, meaning no centralized authority is involved. It is open to anyone that wants to contribute their excess computation power by hooking up a specialized hardware device to the network. In return, if miners are successful in confirming a block of transactions, not only do they receive a Bitcoin reward of 12.5 BTC, but they also receive all of the transaction fees that were included within the block.
There are many different ways that a blockchain can confirm a set of transactions and this is known as a consensus mechanism. Bitcoin uses a mechanism called Proof-of-Work, or PoW for short. The way PoW works is the underlying software creates a cryptographic algorithm that resembles a difficult mathematical puzzle. This randomly generated puzzle is so complex that it requires significant computational power to solve it.
When the Bitcoin and PoW system attempts to validate a block of transactions, it does so in a period of 10 minutes. During this time, each and every miner will use their device in an attempt to solve the puzzle. To do so, the mining device operates on a 'trial and error' basis, insofar that it attempts millions of potential answers to the puzzle every second. The first mining device (known as a node) that is successful in solving the sum is the subsequent winner in that specific block.
As mentioned earlier, there are approximately 10,000 individual nodes that are all competing with each other to solve the puzzle first. In theory, the node that is able to generate the most computational power (known as hashing power) will stand the best chance of winning the mining reward, as it is able to generate more potential answers to the puzzle each second.
Therefore, mining is often referred to as an arms race, as those with the most powerful devices are often more successful in winning block rewards.
Let's briefly find out why this is and how it might affect your chances of solo mining Bitcoin.
The Bitcoin mining Arms Race.
During the first few years of Bitcoin launching, the vast majority of mining was facilitated by simple GPU units. As the amount of miners in operation was minute in quantity, the underlying algorithm that had to be solved was significantly less difficult than it is today. This not only allowed miners to use inexpensive devices, but it also kept electricity costs at an absolute minimum.

[Bitcoin]

However, as the value and real-world adoption of Bitcoin has grown over time, as have the amount of miners that are looking to enter the space. The result of this is that the algorithmic difficulty of the puzzle has increased exponentially, meaning that GPU devices can no longer compete.
Instead, GPUs have been replaced by highly powerful ASICs (Application-Specific Integrated Circuit), which have the ability to generate a significant amount of hashing power. At the time of writing in 2018, the most powerful Bitcoin ASIC device is the DragonMint T1, which can generate 16TH per second.
An even greater issue with the current state of play of Bitcoin mining is that the vast majority of success is dominated by a small number of mining pools. This is where individual miners pool their hashing power together in order to boost the likelihood that someone in the pool successfully mines a block. The members of the pool then divide the rewards between their members. The prevalence of mining pools has made it very difficult for solo miners to compete.
Essentially, this leaves you with two options. If you are interested in solo mining Bitcoin, then your odds of successfully mining a block are drastically lower than if you were to join a pool. However, if you are successful, you would receive the 12.5 BTC block reward in its entirety, along with all of the subsequent transaction fees.
On the other hand, if you are more interested in joining a pool, your chances of winning a block reward are significantly higher, but you will only receive a very small proportion (relative to the amount of hashing rate you contribute) of the reward. Moreover, most mining pools keep the transaction fees for themselves.
Nevertheless, we will now show you what you need when solo mining Bitcoin.
Solo Mining Bitcoin - Hardware.
To get your Bitcoin solo mining journey on its way, you will first need to invest in a specialized hardware device. Don't forget, the days of being able to mine Bitcoin with a basic GPU are over, so you will need to get yourself an ASIC.
First and foremost, there is no doubt that by purchasing the most powerful ASIC device available on the market, you will increase your chances of beating your fellow miners. The aforementioned DragonMint T1 costs in the region of $2,700, which is out of reach for many.
If financial resources do not stretch that far, then you will need to get a slightly less-powerful model. To give you an understanding of how much the most popular devices cost, along with their respective hashing rate power, take a look at the screenshot below.
As you will see, there is a correlation between the price and the amount of hashing power the ASIC device is able to produce.
Before making a purchase, it is important to remember that you should typically only ever buy from the manufacturer's official website, or a website that is listed as an official vendor. You should be very cautious when purchasing a mining device second hand or from an unverified source. The reason for this is that the device may have been tampered with, meaning that the bad actor might be able to re-direct your hashing power.
So now that you know the requirements of hardware, let's take a look at what software you will need.
Solo Mining Bitcoin - Software.
When you purchase an ASIC hardware device, the vast majority of suppliers will provide you with the mining software. If this is the case, you should only ever use the software that is included with your device, rather than attempting to use a third party alternative.
You will need to install the relevant software file on to your desktop device and follow the on-screen instructions. At an absolute minimum you will need to enter the public address that you want your mining rewards sent to.
Mining software also allows you to play around with the underlying settings, which can include the amount of hours you want the device to mine, along with how much power you want the device to generate.
Before changing any fundamental settings, it is always worth checking the instructions that are provided by the manufacturer.
At this point in your mining endeavor, you should now have a specialized ASIC hardware device, as well as the required software installed. You can now sit back and let your mining device do all of the hard work! Let's find out what kind of results you can expect.
What to Expect From Your Efforts.
If you are looking to find out how long it will take you to successfully mine a block, or how much money you can make over a certain period of time, the answer will ultimately depend on a number of factors. Take a quick look at the bullet points below, which indicate some of the things that will influence your ability to make a profit:
How much hashing power is your ASIC device able to produce? How many ASIC devices do you have connected to the network? How many other nodes are currently on the network? How expensive are electricity costs in your country? What is the current difficulty rate set at? What is current value of Bitcoin?
All of the above factors will determine your solo mining earning potential. Fortunately, there are now websites that allow you to enter your individual circumstances, subsequently giving you an estimate on profitability.
Solo Mining Bitcoin: The Verdict.
If you have read our guide from start to finish, you should now have a good idea of the many factors that you need to consider prior to starting your solo mining journey. The current state of play in the Bitcoin industry is that the vast majority of block rewards are now won by the large mining pools.
As a result, solo mining is now a lot more difficult than it was during the early years of Bitcoin. Nevertheless, if you are still keen on giving it a go, just make sure that you consider the hashing power capabilities of the ASIC device you are buying. If it is inferior to other devices on the market, you are reducing your chances of success. Moreover you also need to consider the cost of electricity in the nation you are operating in, as this could be the difference between profit and loss.

Why You Are Here.
An article addressing the pros and cons of solo and pooled mining can often answer questions easier than simply asking in: #bitcoin-mining. Additionally, this page can serve as a reference for members of #bitcoin-mining to direct those with questions.
What this topic discusses.
The purpose of this page is to explain what the differences between pooled mining and solo mining. This Topic will give pros and cons of each to aid in the decision of a mining approach.
What is Pooled Mining?
Pooled mining "pools" all of the resources of the clients in that pool to generate the solution to a given block. When the pool solves a block, the 6.25 BTC generated by that block's solution is split and distributed between the pools participants.
What is Solo Mining?
Solo mining is when a miner performs the mining operations alone without joining a pool. All mined blocks are generated to the miner's credit.
Mining¶
Mining adds new blocks to the block chain, making transaction history hard to modify.
Introduction¶
Mining today takes on two forms:
Solo mining, where the miner attempts to generate new blocks on his own, with the proceeds from the block reward and transaction fees going entirely to himself, allowing him to receive large payments with a higher variance (longer time between payments)
Pooled mining, where the miner pools resources with other miners to find blocks more often, with the proceeds being shared among the pool miners in rough correlation to the amount of hashing power they each contributed, allowing the miner to receive small payments with a lower variance (shorter time between payments).
Solo Mining¶
As illustrated below, solo miners typically use bitcoind to get new transactions from the network. Their mining software periodically polls bitcoind for new transactions using the “getblocktemplate” RPC, which provides the list of new transactions plus the public key to which the coinbase transaction should be sent.
Solo Bitcoin mining В¶
The mining software constructs a block using the template (described below) and creates a block header. It then sends the 80-byte block header to its mining hardware (an ASIC) along with a target threshold (difficulty setting). The mining hardware iterates through every possible value for the block header nonce and generates the corresponding hash.

[Bitcoin]

If none of the hashes are below the threshold, the mining hardware gets an updated block header with a new merkle root from the mining software; this new block header is created by adding extra nonce data to the coinbase field of the coinbase transaction.
On the other hand, if a hash is found below the target threshold, the mining hardware returns the block header with the successful nonce to the mining software. The mining software combines the header with the block and sends the completed block to bitcoind to be broadcast to the network for addition to the block chain.
Pool Mining¶
Pool miners follow a similar workflow, illustrated below, which allows mining pool operators to pay miners based on their share of the work done. The mining pool gets new transactions from the network using bitcoind . Using one of the methods discussed later, each miner’s mining software connects to the pool and requests the information it needs to construct block headers.
Pooled Bitcoin mining В¶
In pooled mining, the mining pool sets the target threshold a few orders of magnitude higher (less difficult) than the network difficulty. This causes the mining hardware to return many block headers which don’t hash to a value eligible for inclusion on the block chain but which do hash below the pool’s target, proving (on average) that the miner checked a percentage of the possible hash values.
The miner then sends to the pool a copy of the information the pool needs to validate that the header will hash below the target and that the block of transactions referred to by the header merkle root field is valid for the pool’s purposes. (This usually means that the coinbase transaction must pay the pool.)
The information the miner sends to the pool is called a share because it proves the miner did a share of the work. By chance, some shares the pool receives will also be below the network targetвЂ"the mining pool sends these to the network to be added to the block chain.
The block reward and transaction fees that come from mining that block are paid to the mining pool. The mining pool pays out a portion of these proceeds to individual miners based on how many shares they generated. For example, if the mining pool’s target threshold is 100 times lower than the network target threshold, 100 shares will need to be generated on average to create a successful block, so the mining pool can pay 1/100th of its payout for each share received. Different mining pools use different reward distribution systems based on this basic share system.
Block Prototypes¶
In both solo and pool mining, the mining software needs to get the information necessary to construct block headers. This subsection describes, in a linear way, how that information is transmitted and used. However, in actual implementations, parallel threads and queuing are used to keep ASIC hashers working at maximum capacity.
getwork RPC¶
The simplest and earliest method was the now-deprecated Bitcoin Core getwork RPC, which constructs a header for the miner directly. Since a header only contains a single 4-byte nonce good for about 4 gigahashes, many modern miners need to make dozens or hundreds of getwork requests a second. Solo miners may still use getwork on v0.9.5 or below, but most pools today discourage or disallow its use.
getblocktemplate RPC¶
An improved method is the Bitcoin Core “getblocktemplate” RPC. This provides the mining software with much more information:
The information necessary to construct a coinbase transaction paying the pool or the solo miner’s bitcoind wallet.
A complete dump of the transactions bitcoind or the mining pool suggests including in the block, allowing the mining software to inspect the transactions, optionally add additional transactions, and optionally remove non-required transactions.
Other information necessary to construct a block header for the next block: the block version, previous block hash, and bits (target).
The mining pool’s current target threshold for accepting shares. (For solo miners, this is the network target.)
Using the transactions received, the mining software adds a nonce to the coinbase extra nonce field and then converts all the transactions into a merkle tree to derive a merkle root it can use in a block header. Whenever the extra nonce field needs to be changed, the mining software rebuilds the necessary parts of the merkle tree and updates the time and merkle root fields in the block header.
Like all bitcoind RPCs, “getblocktemplate” is sent over HTTP. To ensure they get the most recent work, most miners use HTTP longpoll to leave a “getblocktemplate” request open at all times. This allows the mining pool to push a new “getblocktemplate” to the miner as soon as any miner on the peer-to-peer network publishes a new block or the pool wants to send more transactions to the mining software.
Stratum¶
A widely used alternative to “getblocktemplate” is the Stratum mining protocol. Stratum focuses on giving miners the minimal information they need to construct block headers on their own:
The information necessary to construct a coinbase transaction paying the pool.
The parts of the merkle tree which need to be re-hashed to create a new merkle root when the coinbase transaction is updated with a new extra nonce. The other parts of the merkle tree, if any, are not sent, effectively limiting the amount of data which needs to be sent to (at most) about a kilobyte at current transaction volume.
All of the other non-merkle root information necessary to construct a block header for the next block.
The mining pool’s current target threshold for accepting shares.
Using the coinbase transaction received, the mining software adds a nonce to the coinbase extra nonce field, hashes the coinbase transaction, and adds the hash to the received parts of the merkle tree. The tree is hashed as necessary to create a merkle root, which is added to the block header information received. Whenever the extra nonce field needs to be changed, the mining software updates and re-hashes the coinbase transaction, rebuilds the merkle root, and updates the header merkle root field.
Unlike “getblocktemplate”, miners using Stratum cannot inspect or add transactions to the block they’re currently mining. Also unlike “getblocktemplate”, the Stratum protocol uses a two-way TCP socket directly, so miners don’t need to use HTTP longpoll to ensure they receive immediate updates from mining pools when a new block is broadcast to the peer-to-peer network.
Resources: The GPLv3 BFGMiner mining software and AGPLv3 Eloipool mining pool software are widely-used among miners and pools. The libblkmaker C library and python-blkmaker library, both MIT licensed, can interpret GetBlockTemplate for your programs.
How to Setup a Bitcoin mining Computer?
Hello and welcome to the second Bitcoin mining tutorial, where I am going to cover how to setup a Bitcoin mining computer.
Luckily for you, our method is to mine the crypto altcoins and then get paid in Bitcoin, so you don't have to deal with specialized mining hardware(like ASIC), and can mine with your PC.
So, in the most basic scenario, you don't really need to setup a mining PC. Just turn on the PC that you already have, install one of the mining apps featured on our website, and you can start mining Bitcoin in minutes.
However, if you don't have a PC, or want to build a separate one to use for Bitcoin mining only, here's what you're going to need:
What you need to build a Bitcoin mining Computer.
Motherboard. Every PC needs a motherboard, and a mining machine is no exception. You want it cheap, and supporting as many GPUs as possible(so you can scale and upgrade in the future). CPU . This one should be cheap as well, as we are not going to mine with a CPU, but simply need it to serve the GPUs and the machine. RAM. Just pick a 4GB DDR4, or add some more if you're going to use multiple heavy GPUs. Power supply. This one shouldn't be cheap. You want a high quality, stable power supply that makes it possible for your mining machine to work 24/7. You also want it strong- 1000W+, so you can attach multiple GPUs in the future. Graphic card(GPU). The stronger the better, but also the less power it consumes the better. The more you mine, the more power you need to pay for. And a GPU with low electricity usage is going to pay off in the long run. Hard drive . You can go here with a cheap and small one, my advice is to pick a small SSD which will bring additional stability to your mining PC. Peripherals. The mining rig DOES NOT need peripherals in order to work. If you already have a keyboard, mouse and monitor at your home, you can simply borrow them while setting up your mining apps and then disconnect them, as your PC can mine without them.
Bitcoin CPU Mining.
For most people, mining with CPU is not going to work, as most CPUs are very slow when it comes to mining, plus they are not scalable- there are motherboards allowing you to attach as much as 20+ GPUs, while motherboards supporting more than one CPU are a rarity.
Still, there are some newer CPUs that are performing very well at mining. For example, the AMD Ryzen Threadripper 1950X which comes with 16 cores, 32 threads and an amazing 32MB L3 cache. Some tests are even showing this CPU performing twice better than GTX 1080 Ti at mining some cryptocurrency like Monero.
If you are one of those lucky people that have a new generation CPU, you may as well try mining with it. Here's a list of some more popular mining CPUs.
Why Does Bitcoin mining Use GPU.
We already mentioned one very good reason- and that's scalability. Being able to attach multiple GPUs is a strong factor for any semi serious mining operation. But there's more- even an average GPU is 10x better at mining than average CPU. And here's why:
The CPU and GPU have a different purpose and architecture. The CPU consists of small amount of cores, and is good at solving complex tasks as well switching between them. On other hand, the GPU consists of much more cores which are "dumber", yet there are so many of them that they can join and do a lot of parallel work.
And it happens that for Bitcoin and many other altcoins, the GPU is just more suitable and more efficient at mining.
How to Set Up a Bitcoin Miner yourself? [in 2020]
To start mining bitcoins can be a bit overwhelming as there are several complicated steps involved, but we have provided a detailed guideline that can help you to get started with Bitcoin mining.
Bitcoin mining is a way to earn bitcoins as rewards by confirming the blocks on the network. It might sound like a complicated process to start with, but we have detailed all the steps that will help you set up a bitcoin miner yourself.
Bitcoin mining is a way where you compete with your mining hardware with everyone on the network to earn bitcoins. It is a very crucial process that keeps the network secure.

Should YOU be GPU MINING Cryptocurrency in 2020?!|14:39

[Bitcoin]

Follow the below guidelines to set up a bitcoin miner successfully.
1. Get a Bitcoin mining hardware.
In order to begin mining bitcoins, the first thing required is to acquire a Bitcoin mining hardware, also called a mining rig. Earlier, it was possible to mine bitcoin from your computer or high-speed video processor card, but that is not possible today. Bitcoin mining consumes a lot of electricity nearly as much as profits earned, so it is important to only use bitcoin miners that specifically build for that purpose. Some of the best bitcoin miners currently are AntMiner S7, AntMiner S9, and Avalon6.
Note: Some bitcoin miners come with their own internal power supplies, while some have to be bought external PSU (Power Supply Units).
2. Download a free bitcoin miner software.
Once you have acquired the most suitable bitcoin miner, you will be required to download a special program that will be used for Bitcoin mining. Currently, there are several programs out there that are used for Bitcoin mining. CGminer and BFGminer are among the most popular programs used for mining. To determine the estimated profits for mining bitcoin, you can use a bitcoin miner calculator.
Note: EasyMiner software works on Windows, Linux, and Android machines and not on Mac OS.
3. Join a Bitcoin mining pool.
Once you have successfully installed a Bitcoin mining software, then you will be required to join a Bitcoin mining pool. These pools are groups of Bitcoin miners working together to solve a block and share in its rewards. Without joining a Bitcoin mining pool , you can mine bitcoins for a year and still not get any reward.
Note: BTC.com is a public mining pool that can be joined and mines 15% of all block.
4. Set up a Bitcoin Wallet.
After joining the Bitcoin mining pool, you will need a bitcoin wallet to receive the bitcoins you mine. You can create a new bitcoin wallet or use an existing one. It is highly recommended to keep your bitcoin wallet secure by enabling two-factor authentication. Now you are all set to earn bitcoin in rewards for making the network more secure.
Note: 65% of the total Bitcoin mining happens in China.
Every four years bitcoin network goes through a halving event, which reduces the bitcoin reward earned by miners in half. The next halvening event is scheduled to take place in May 2020. If you decide to mine bitcoins , it is highly advised to check the laws and regulations regarding it in your country.
How to set up a Bitcoin miner.
Setting up a Bitcoin miner can be quite a complex task. But with a bit of effort and time it should be easy to get the hang of.
(Alternatively, you can also buy a cloud mining contract with Hashflare or Genesis Mining.)
If you have chosen a mining rig through using our guide and calculator then most of the hard work is done.
If you've bought the rig as an off the shelf product ready to go then it should be as easy as plugging it in and choosing a mining pool to join. Your wallet should be hooked up too all ready to run.
If your rig or FGPA or graphics card is not ready to run then you need to do a quick few steps - which can take a bit of time.
Step 1: Download the full Bitcoin client. This can take quite a few days depending on your download speed.
Step 2: Then you need to download some Bitcoin mining software - or the programme that tells your mining hardware how to run.
Step 3: Choose a mining pool otherwise you might end up with a long time before solving your first block.
If you have ordered a miner that comes with a predefined method of connecting to the network the process can sometimes be quite difficult. For example the Antminer U3 63 GH can be quite tricky to get up and running as it requires you to download drivers and run CGMiner yourself - later versions of CGMiner have reduced the complexity of this process.
With the BitMain Antminer S1, S2 & S3 there are also some difficult steps to be followed - mostly to do with defining IP addresses and switching IP address protocols which can mean logging into your own router to find out what address the miner has been signed (quite daunting for some) - with instructions assuming a high level of knowledge by the user with a lot of basic information lost in translation.
However in terms of simplicity Spondoolies tech is probably the most user friendly in terms of set up. Miners such as the SP20 and SP10 can be plugged into your router, and after following five sets of simple and clear instructions can be up and running in five minutes.
Another key point to remember is the power supply you are using. Some miners come with their own internal power supplies, whilst some have to be bought external PSU (power Supply Units). These units have to be bought with the requisite power to coincide with that of the mining chips. For example the Spondoolies tech SP20 needs 1200 Watts of power with a 10-20% margin - so two corsair 750W PSU's will be more than ample.
It is also important to remember that you need to complete the circuit on standard PSU units - although this can sound and look dangerous or scary it is in fact a very low risk and simple operation.
All you need to do is complete the circuit for the PSU allow electricity to flow - and as they were designed to power motherboards this means tricking the PSU into thinking it is plugged in normally, or shorting the 24 pin motherboard attachment. Simply take the largest (24 pin connector) and put a paperclip from the green wire to any one of the black wires and you will have completed the circuit and the PSU will now switch on. The voltage is extremely low so there is no need of insulation or worry of electrocution if the wires are bare.
Also remember that if the unit you are buying doesn't come with a PSU this can become quite a significant part of the initial capital outlay. For example the SP20 in Dec 2014 could be bought for $500 with two corsair power supplies costing $200 dollars or so. When calculating your returns and investment metrics be sure to include your full costs.
Best Windows Setup, Configuration, Tweaks For Mining.
Since i received lots of question about my windows configuration , version or drivers, i decided to make post about it.
Although there is not that much to talk about, but i think those settings are very important and a must for each mining rig, if you do other things that are not found here, post them in comments and ill update!
This windows configuration can be applied on any type of altcoin mining like Ethereum, Ethereum Classic, ZCash, Zclassic, Monero, PascalCoin, Expanse, Ubiq, Decred etc..
Here is how i tweak my windows for a mining rig!

19 x GPU MINING RIG FINALLY WORKS!|16:05

[Bitcoin]

Windows Installation & Configuration for Mining Rig.
Important:
Do not plug the Ethernet cable to your mining rig while windows installation or after that Plug only ONE GPU in the PCI Express 16x slot with usb riser I have always used 120GB SSD drives (you can use bigger, there is no restriction) Always used just one partition C: (if you have a bigger SSD like 240 then you can create additional partition and use it to "mine" Storj)
Windows version for Mining Rig.
Motherboard and Bios.
Depending on what motherboard you will be using, some of them needs some BIOS modifications to make it work properly with USB Risers or anything else. For this, i will take as example "Biostar TB85" and "Z170A Gaming Pro Carbon"
For Biostar TB85 i had to do the following BIOS modifications :
Set CPU fan control to auto, it was 100% all the time Set PCIe Speed from Auto to Gen1 Last thing was to modify " Restore on AC/Power Loss ", set it to " Power On" or "Last State " (if power goes off and after a while is back on, the rig will start automatically) Biostar TB85 BIOS Restore AC Power LossBiostar TB85 BIOS PCIe Speed Gen1.

Windows 10 Registry Tweaks For Mining.
Once windows is full installed and booted for the first time i always run the Windows 10 Registry tweaks for mining.bat file https://mega.nz/#!8gZzjQaa!Dt4wE0WEo8nZkui_-cAAXL4mb4YlO6CJgFZTXKq9pnQ (i am not disabling everything, just things that i think wont be needed, windows update, cortana, crash reports etc..) Back Up Your Registry or create a restore point Run in administrator mode Once everything is applied, restart the rig List of Tweaks Replace Utilman with CMD Disable Cortana, Bing Search and Searchbar Disable automatic Windows Updates Disable Hibernation Disable tracking services Disable WAP Push Message Routing Service Disable Windows Search Disable Superfetch Disable Windows Defender Disable OneDrive Disable Quick Access as default view in Explorer show computer shortcut on desktop Show file extensions Disable lockscreen Enable classic control panel view Hide indication for compressed NTFS files Disable Windows Update sharing Remove Pin to start Classic vertical icon spacing Remove versioning tab from properties Disable jump lists Remove telemetry and data collection Change Logon screen background with accent color Disable Windows Error Reporting Removing Windows default apps Blocking Telemetry Servers windows 10 registry tweaks for mining.
Stop Windows Update #DoubleCheck.
In RUN type " services.msc ", the services page will be open Search for " Windows Update " Click " Stop " if status is " Live " or " Checking/Running " Select " Disabled " on " Startup type " Apply & Restart Do it again and make sure that it is disabled Also if you want you can disable more services.. windows 10 sop updates 2windows 10 sop updates 1.
Increase Virtual Memory.
In search type " This PC ", right click on it and choose " Properties " Then click on " Advanced System Settings " On " Advanced " tab where it says " Performance " click on " Settings " Click " Advanced " tab At the bottom you will see " Virtual memory ", click on " Change " 1. Uncheck "Automatically manage paging file size for all drives " 2. Check " Custom size " 3. In the " Initial size (MB) " type: 3000 (or directly 16000) 4. In the " Maximum size (MB) " type: 16000 (or more like 20k) 5. Click " Set " , then " OK " and " Apply " Restart the rig increase virtual memory 1increase virtual memory 2.
Power Plan and Options.
In search type " Power Options " Click on " Show additional plans " Select " High Performance " plan Then still on " High Performance " plan, click " Change plan settings " Select " Never " on all four selections for " Turn off the display " and " Put the computer to sleep " Click " Change advanced power settings " and look for " PCI Express " -> " Link State Power Management ", make sure it is set to " OFF ", usually it is but better to check on that Restart the rig power option high performance 1power option high performance 2.
Before to continue further, please share this thanks!
AMD Driver Version and Install/Uninstall.
I usually test the rig with this two driver versions!
VERY IMPORTANT: When you want to try a different driver version, use Display Driver Uninstaller in safe mode to uninstall the current driver, it will erase every track of previous video driver, download here: http://www.guru3d.com/files-details/display-driver-uninstaller-download.html.
Basically this is it.. ill update this post once i have new configurations!
