How to choose and connect to a Bitcoin mining pool.
Mining solo, while sometimes more profitable, it's usually not the right choice for most miners. When mining solo, you are doing all the work alone which means that you'll receive the entire block reward, the problem is that mining is also based on a luck factor, which means that if your hashpower isn't high enough, you may never see a reward come your way. With pool mining, however, this variance is eliminated and you recieve payments that correspond to the portion of the work that you have done.
If you are deciding to join a Bitcoin or altcoin mining pool there are quite a few considerations to take into account - mainly their method of distributing the block reward and the fees they charge for managing the pool. Pools also try to stop cheating by miners - i.e. for them to swap between pools. l.
Today we want to teach you some aspects of pool mining in the hope that they will help you choose a mining pool that best fits your needs.
You can check out our mining pool list here. Make sure to read the reviews and to check the features carefuly. You will also find a list of servers by locaiton and coin in the pool description.
The main consideration is the fees, which vary according to which model of payment distribution the mining pool is operating and determines which party is assuming the risk - the miners or the mining pool operator. If the mining pool operator is assuming the risk, then the fees are higher, and if the miners assume the risk then fees are lower.
The fees usually range from 0% to 4%. The standard fee for mining pools is usually 1%, so if you spot a pool with a higher fee check its payment method and other features. If there is a pool with similar features and payment method but smaller fee, you'll want to choose the second option.
Sometimes a pool will have a 0% fee. This is very unusual and it most often means that you are dealing with a new pool that has no fee in an effort to attract customers. Some pools, however, actually rely on donations and other methods, so if you find a 0% fee, you'll want to keep an eye on any fee changes.
You can check out our mining pool list here and organize it by fee.
The model where the mining pool operator assumes all the risk is when they guarantee a payment per each proof of work - or potential hash solution - that their miners offer. For example if the total network is 100GH, the mining pool operating this Pay Per Share (PPS) method has a hash rate of 10GH, and the block reward is 25 Bitcoins, then the expected return is 2.5 Bitcoins per block.
The pool will give money to their miners even if their pool hasn't successfully mined the block, meaning the risk of lumpy payments is assumed by the operator, and hence why the fees are at the higher end of the range at 10%. Miners will then only receive an expected return of 2.25 Bitcoins per block distributed proportionally by how much hashing power they have contributed towards the block.
When the miners assume the risk the fees are generally lower as they take on the risk that they might not solve a block for an extended period of time and receive no payment of Bitcoins.
There are varying methods of this with the aim of keeping the pool hashing power stable.
- Proportional - the simplest method whereby for each block, the reward is split between the hashing power contributed proportionally by the miners of the block. - Pay Per Last N Shares - PPLNS - looks at the last N shares instead of just the last block. This smooth's the returns for mining rig operators if they haven't been connected for one reason or another. If they contributed to the majority of Bitcoin blocks 1-6, when a reward was found by their pool in block 7, for which they had become disconnected through no fault of their own, then they are still eligible for payouts depending on the time of N.
There are other inventions and variations that have been implemented. For example the DGM method (Double Geometric Method), where the operator receives some payments over short rounds and distributes them over longer rounds. There are also some other ways where the more recent proofs of work are allocated a higher weighting in terms of the proportion they are eligible for.
Some pools have extra fees on top of PPS (Pay Per Share) schemes - but in generally fees range from 0% for Proportional and PPLNS pool management schemes to 10% for PPS schemes. There also pools that offer the ability to merge mine other SHA-256 coins as well as Scrypt pools that allow you to merge mine other popular crypto currencies such as Dogecoin and litecoin.
Over the time, many different payment systems have been developed. Most altcoin pools use the Prop or PPLNS payment system. However, there are several, including:
CPPSRB - Capped Pay Per Share with Recent Backpay.
DGM - Double Geometric Method. A hybrid between PPLNS and Geometric reward types that enables to operator to absorb some of the variance risk. Operator receives portion of payout on short rounds and returns it on longer rounds to normalize payments.
ESMPPS - Equalized Shared Maximum Pay Per Share. Like SMPPS, but equalizes payments fairly among all those who are owed.
POT - Pay On Target. A high variance PPS variant that pays on the difficulty of work returned to pool rather than the difficulty of work served by pool.
PPLNS - Pay Per Last N Shares. Similar to proportional, but instead of looking at the number of shares in the round, instead looks at the last N shares, regardless of round boundaries.
PPLNSG - Pay Per Last N Groups (or shifts). Similar to PPLNS, but shares are grouped into "shifts" which are paid as a whole.
PPS - Pay Per Share. Each submitted share is worth certain amoutripnt of BC. Since finding a block requires shares on average, a PPS method with 0% fee would be 12.5 BTC divided by . It is risky for pool operators, hence the fee is highest.
Prop. - Proportional. When block is found, the reward is distributed among all workers proportionally to how much shares each of them has found.
RSMPPS - Recent Shared Maximum Pay Per Share. Like SMPPS, but system aims to prioritize the most recent miners first.
Score - Score based system: a proportional reward, but weighed by time submitted. Each submitted share is worth more in the function of time t since start of current round. For each share score is updated by: score += exp(t/C). This makes later shares worth much more than earlier shares, thus the miner's score quickly diminishes when they stop mining on the pool. Rewards are calculated proportionally to scores (and not to shares). (at slush's pool C=300 seconds, and every hour scores are normalized)
SMPPS - Shared Maximum Pay Per Share. Like Pay Per Share, but never pays more than the pool earns.
You will also want to take into account the minimum payout. This defines the minimum amount of coins you are allowed to withdraw (or to receive automatically). Some pools allow you to set a limit above the minimum, which allows you to save money on transaction fees. When choosing a mining pool, you will want to check the minimum payout, the payout period, and weather the pool or the user pays for the transactions fees on withdrawals.
You can check out our mining pool list here and filter it by payment system.
The first thing you'll have to consider is, of course, the cryptocurrency that you would like to mine. The most popular at the moment are Zcash, Ethereum, and Ethereum Classic, among others. These are currently the most profitable ones. You can always compare your profits with each currency through the calculator tool that we have available. Of course, these numbers are subject to change has the price, mining difficulty, and network hashrate change, so it's advisable that you take these into account and that you check on them regularly.
Some mining pools allow Merge Mining, which means that your can mine two cryptocurrencies at once without losing efficiency in neither. This, however, is only available with some algorithms.
Another type of pool to consider is a multi-pool. These allow you to choose from several cryptocurrencies to mine and converts your profits into Bitcoin automatically. If you are planning to mine an altcoin but want to exchange it for BTC, these may be useful to you. Check out multi.pools here.
You can check out our mining pool list here and filter them by currency.
If you're located in Europe and mining on a Chinese server, you may not get the best results. Check if your pool has a servers in your country/continent and if so, check the URL for those servers. This will allow you to mine more efficiently.
Vardiff stands for Variable Difficulty. It is used to regulate the difficulty of the shares you recieve to work on. This benefits both low hashrate and high hashrate miners as the difficulty will regulate itself to best fit your hashrate. While some mining pools have Vardiff, others will have multiple ports for different difficulties. If your pool has no Vardiff, you may want to test different ports for different difficulty.

Best VPS For Mining 2020.
Crypto mining is one of different ways to profit from cryptocurrencies, especially for people who don't want to put their capital at risk by trading cryptocurrencies on broker platforms. Mining will never bring the returns of successful altcoin trades, but it delivers stable returns without the risk of losses.
The times when you could mine Bitcoin at home are long ago. This cryptocurrency not only is the most popular and most expensive one - it can even be called the mother of all cryptocurrencies and the crypto reserve currency. For private households it is impossible to mine Bitcoin since you need special equipment that only mining companies can afford.
Top VPS Hosting Providers**:
max RAM: 6 GB max Storage: 75 GB max Bandwidth: 2 TB max CPU: 2.
max RAM: 32 GB max Storage: 320 GB max Bandwidth: 10 TB max CPU: 8.
max RAM: 16 GB max Storage: 160 GB max Bandwidth: 15 TB max CPU: 8.
max RAM: 8 GB max Storage: 260 GB max Bandwidth: 6 TB flexible CPU Cores.
max RAM: 8 GB max Storage: 100 GB max Bandwidth: 3 TB max CPU: 8.
max RAM: 64 GB max Storage: 400 GB max Bandwidth: 10 TB max CPU: 16.
** Note that the hosters mentioned above might tolerate crypto mining activities as long as you don't run scripts that force a maximum CPU usage exceeding the CPU of your VPS plan. So crypto mining is not explicitly forbidden with those VPS hosters according to their terms of service, but there are clauses that refer to mining activities, such as at Virmach:
But which coins promise the highest returns in 2019 while being easily minable at home without super expensive extra equipment? Many new cryptocurrencies have appeared and it gets harder and harder to keep the overview.
There are couple of altcoins that count as worth mining, still or especially in 2019. They are not that expensive and some can be mined without special difficulties, even with an ordinary computer like Monero (XMR) - the best anonymous coin there is.
Which Cryptocurrency To Mine - The Right Choice.
When choosing the right cryptocurrency, you should be careful. Don't look at the price, how much the cryptocurrency currently costs, but how easy it is to mine and how good the prospects are for the particular altcoin. For example, long-term growth in price should be very likely and it should be able to recover the investments you spent on its extraction.
In addition, the choice of cryptocurrency and mining service depends on whether it is possible to withdraw funds.
This article tries to accumulate the most promising cryptocurrencies. Altcoins that can be mined from virtually any device, including a computer, provided it has a powerful processor and a suitable graphics card.
By the way, the topic of the graphics card is particularly acute, because with Bitcoin mining the use of a video card was abandoned - it became too expensive. Therefore, the income from mining is practically lost against the background of the costs.
But this article describes the most promising alternatives that are beneficial for mining cryptocurrencies in 2019. Here are some of them:
Monero (XMR)
One of the coins that can be mined by individuals is Monero. So it's definitely worth looking for the best VPS for Monero mining since this coin is being created through CPU mining which can easily be executed by a external rented server. So you can easily mine Monero on your home desktop computer. Additionally you could even mine XMR on your mobile phone.
Ethereum (ETH)
Ethereum. This currency will prove itself as heir to Bitcoin, but it is growing incredibly fast. If it cost only $40 at the beginning of 2017, it will cost $893 at that time, i.e. one year later.
But the currency is unstable and must be recognized. There are inherent jumps in price - if it costs more than $800 today, the price could fall to $600-700 a piece tomorrow.
Therefore, you should think before investing in mining of this cryptocurrency.
Litecoin (LTC)
Litecoin. Also a very interesting option for mining. The cost of this coin does not make you sweat. Everything is more than modest &ndas; only 250 dollars per Litecoin at the time of writing this post.
Competition in the mining of this cryptocurrency is minimal, which makes LTC mining much easier. In addition, experts say that Lightcoin is the most stable currency available and its exchange rate is subject to smaller jumps.
Dash (DASH)
A promising currency was added to the rating. She belongs to the "youngest", but has already made a lot of noise. Experts say DASH has a chance to grow to several thousand dollars. Start with the fact that a few months ago it still cost 11 dollars and is now worth 1165 dollars.
Each of these cryptocurrencies can be described as the most profitable coins for mining, but whether this is really the case will be shown in practice.
Here even more coins you should have a look at as they can be mined at home:
Vertcoin (VTC)
ZENCash (ZEN)
Doge Coin (DOGE)
Bytecoin (BCN)
AEON (AEON)
Electroneum (ETN)
Feathercoin (FTC)
Profitability Of Mining.
Some will say that mining in 2019 is no longer profitable and many will agree with you. But in spite of everything, it depends on the cryptocurrency.
To find out which altcoins can still be mined for reasonable profits, there is the service "WhattoMine.com".
This service is specially developed for those who work in mining. It allows you to calculate the most profitable cryptocurrency you can mine with your graphics card or Asics.
On the page, select the type of hardware (graphics card or Asic), then enter the correct information in the specific areas: Performance of your devices (hashing speed) and energy consumption.
Then press "Calculate" and you will receive information on how much you can earn when you mine this or that cryptocurrency.
Which Hardware To Use.
CPU (Mining on the processor). Given the current complexity, such mining is no longer profitable.
Mining on the operational memory, for example, if the currency uses the Scrypt encryption algorithm. You could mine, but it's not very profitable now.
GPU (Mining on the graphics card). The disadvantages of this method are quite large.
The energy consumption and the price of a good graphics card is also not cheap and despite these disadvantages, this type of mining is by far one of the best. For example, compared to the same mining on ASICs, you can always sell the graphics card at a good price.
There is always a demand and in case of damage it can be repaired within the warranty period. The best graphics card for mining is the GTX 1070 as far as I know.
ASIC (Application Specific Integrated Circuits). These units were specially developed for the mining of cryptocurrencies (bitcoin).
However, the high costs and the high risk are negative, as they are difficult to repair in the event of damage.

Crypto Currency Cabal.
University of Virginia cs4501 Fall 2015.
Problem Set 2: The Blockchain.
Purpose.
The goal of this assignment is for everyone in the class to understand how Bitcoin mining and the blockchain work, and evaluate risks to the blockchain.
Collaboration Policy.
For this assignment, everyone should submit their own assignment and should writeup their own answers to the questions. You may, and are encouraged to, discuss all of the problems with anyone else you want (both on-line using the course web site or any other means you choose, and in person).
Submission.
Submit your answers as a single PDF file using this link. The name of your file should be -ps2.pdf .
Your submission should include clearly marked answers for all the problems (highlighted in yellow). None of the questions require submitting a program, although you may find it helpful to write programs to develop your answers. If the code you write is less than a page, it is best to just include it in the PDF writeup. If it is longer, you may submit separate code files (and mention them in the PDF submission).
Blockchain Consensus.
These questions concern the original bitcoin paper:
What are the assumptions necessary to support Satoshi's claim that it is more profitable for a greedy attacker with a majority of the mining power "to play by the rules"? (other than the assumption that the greedy attacker is a "he")
(a) There is a problem with this scheme unless the bytes of data[ i ] indicate that it is in fact from i -th index. What is this problem?
(b) Suppose we perform a write at position i , both data and signature. Later on, when we read it back, if the signature matches the data, can we be sure that it is indeed the data item we wrote? Explain.
(a) What is the write/read/verify procedure for this system?
(b) How does the cost of reading and writing to the database scale with n (the number of records)?
These questions are related to this paper (and what was covered in Class 10 and Class 11):
Orphaned Blocks are blocks that are submitted to the bitcoin network, and that are valid, but do not become part of the longest (consensus) blockchain.
One way to detect selfish mining is to be on the lookout for "orphaned" blocks, or blocks that were mined but never became part of the final blockchain.
Let's say you set up a node to monitor orphaned blocks, and you are in a favorable position in the network that allows you to observe all orphaned blocks. Assume that the hashing difficulty stays constant and the expected block rate is constant at 10 minutes per block.
(b) Obtain a general formula for expected number of blocks a mining pool with α fraction of the total hashing power should find in t minutes.
For the next questions, you may assume a very simplified network model where you can view the network having two "supernodes": one represents a particular mining pool, and the other represents all other nodes in the network. The latency between the two supernodes is L seconds.
With this simple (but very unrealistic) model, we assume that when one supernode announces a block, all of the rest of the network learns of the new block L seconds later (but no one learns of it before that).
Pool Hopping.
Answer either question 10A or 10B (your choice).
Bonus Opportunities.
The following questions are suggestions for further work, but it is not expected that everyone will solve them. (Note that some of these could be starting ideas for larger projects, although a good answer to any of them would be most impressive.)
Challenge 1. The network model in questions 8 and 9 is very unrealistic. Answer these questions for a more realistic model of the bitcoin network, and compare your results with the actual rates of orphaned blocks. To better detect misbehaving miners, you would want to also look into the contents of the dual blocks (note that the one that was orphaned is not necessarily the one from the selfish miner). There is an API for obtaining orphaned blocks provided by https://api.biteasy.com.
Challenge 2. The analysis in the paper and in class assumed that if the selfish miner is ahead by 2 blocks, it will always win by releasing the blocks when it observes a new block on the blockchain. It could still lose if the rest of the network finds a second block before the selfish miner's blocks have propagated over the network. How does this possibility impact the analysis?
Challenge 3. The site that was demonstrated in Class 11 uses a very simple model to estimate the profitability of a particular bitcoin miner. Produce a better model, and use it to evaluated the expected profit (or loss) for mining hardware such as Antminer S7. A better model would need to capture expected increases in the difficulty, cost of capital, and other costs of mining besides electricity.
Follow the submission instructions at the beginning of this page by 8:29pm on Friday, 9 October.
Mining Bitcoin Using Old Computers and Retro Gaming Consoles.
Bitcoin mining has grown into a vast economy over the past few years as large ASIC-powered mining farms process transactions for the $32 billion dollar market. In the early days, people could mine bitcoins using their central processing units (CPU) and they still can, but the undertaking is extremely inefficient. However, a few people still mess around mining bitcoins using older computers and retro devices merely for the fun of it and for experimentation purposes.
Bitcoin mining With Classic Computers and Retro Gaming Consoles.
The Bitcoin mining ECOSystem is a competitive environment of pools processing transactions while simultaneously securing the network. Miners run special software and use application-specific integrated circuitry (ASIC) to mine bitcoins these days, using chips far more efficient than your standard CPU. Currently, older computers can mine bitcoins at a prolonged rate, but it's still pretty cool to see if a classic system can perform the task of Bitcoin mining.
One bitcoin enthusiast has done just that a few times with older computers. Ken Shirriff is well-known in the bitcoin community for his work on getting the bitcoin symbol added to Unicode. Shirriff also has a popular blog where writes about his projects and how he has mined bitcoins using classic devices from the past. Just recently Shirriff has been working on a Xerox Alto restoration and managed to get the seventies built computer to mine bitcoins at 1.5 hashes/second. The Xerox Alto is a well-known computer classic that was the first device to support a graphical user interface (GUI) in 1973.
"I've been restoring a Xerox Alto minicomputer from the 1970s and figured it would be interesting to see if it could mine bitcoins," explains Shirriff.
I coded up the necessary hash algorithm in BCPL (the old programming language used by the Alto) and found that although the mining algorithm ran, the Alto was so slow that it would take many times the lifetime of the universe to successfully mine bitcoins.
The computer's 1.5 blocks per second is significantly slower than the chips used today. Shirriff details the Xerox Alto's speed would take "5000 times the age of the universe" to mine one block. For demonstration purposes, Shirriff used the input of a successfully mined block to see if the algorithm succeeded. Shirriff's code is available on Github for those who would like to try out Xerox Alto mining.
An Old IBM Mainframe From the Sixties Would Take Roughly 40,000 Times the Current Age of the Universe to Find a Block.
Another project Shirriff worked on back in 2015 was mining with a 55-year-old IBM 1401 mainframe at 80 seconds per hash. This computer was the best-selling computer of the mid-1960s and mainly used for business purposes.
"While modern hardware can compute billions of hashes per second, the 1401 takes 80 seconds to compute a single hash," details Shirriff. "This illustrates the improvement of computer performance in the past decades, most famously described by Moore's Law -- To summarize, to mine a block at current difficulty, the IBM 1401 would take about 5×10^14 years (about 40,000 times the current age of the universe)."
The card deck Shirriff used to compute SHA-256 hashes on the IBM 1401 mainframe.

Lastly, another neat project is another incredibly slow miner built in 2013 out of a 1985 Nintendo Entertainment System (NES). The creator of the NES mining system was joking around with his friend about mining bitcoins with an 8-bit game console. Well, he took that as a challenge and built a Nintendo that communicated with the network and performed SHA256 hashing. For other portions of the project, he did need a Raspberry Pi for computing that did not take place on the NES.
"SHA256 hashing uses many 32-bit operations, and the 6502 in the NES is an 8-bit CPU," explains the retro miner creator. "Initially I thought this would be a significant challenge, but with some modifications, I got an open implementation of SHA256 to compile to a 6502 target using the cc65 compiler."
The Raspberry Pi gets a chunk of data, compiles it into a ROM that includes the SHA256 algo and current target data, and sends it to the console via USB CopyNES. Each ROM computes and tests a single hash.
In the end, the NES miner worked and started searching for blocks with Slush's pool, but the creator said there was plenty of room for build improvements. "What I'm doing now is very slow, and I admit, pretty lame," explains the retro miner's blog post. Additionally, bitcoiners have had great discussions concerning mining bitcoin with other gaming consoles like the Playstation 3.
ASIC Producers Don't Need to Worry About Retro Miners.
Obviously, these types of projects won't be mass adopted to mine excessive amounts of bitcoins like ASICs because it would take many lifetimes to find one block using a retro device. However even though watching an older computer or gaming console mine bitcoins is super slow it's very interesting to see that these devices are compatible with the Bitcoin network.
What do you think about people testing old computers and retro gaming devices with the Bitcoin network? Let us know what you think in the comments below.

Does Ram Matter For Mining?
When it comes to choosing the RAM for your mining rig yes there are some factors to take into consideration.
RAM(random access memory) is basically your computers short term memory storage so that it can readily access information needed to run applications faster. As a rule of thumb the more applications you plan on running on your device the more RAM is required to maintain fast response time from the computer.
Does RAM matter for mining? This size of RAM you use on your mining machine does not have a direct impact on mining performance in most cases. However, there are some guidelines such as minimum OS requirements and motherboard form factor that must be followed to ensure your mining rig runs stable.
So in this guide, I will discuss and answer(to the best of my knowledge) some of the more common questions that get asked from newcomers looking to start building their own mining rigs.
Is 4gb Ram Enough For Mining.
The size of RAM you will need will ultimately depend on the operating system you choose to run your mining machine on. Some miners claim that 4GB is big enough to run Windows 10 while some say get the 8GB and thank your self later.
As for my honest opinion, I say get the 8GB over the 4GB when it comes to Windows 10 and for a few good reasons. The main reason being that if you choose to skimp on RAM you may be faced with lag issues that can make your operating system run slow.
For example, let's say you installed 4GB of RAM on Win10 and you want to open MSI afterburner at the same time your rig is mining Ethereum. You may notice that the program takes forever to open or is sluggish and that's because of the mining software and many behind the scenes processes that Win10 runs are maxing out the RAM capabilities.
Although this problem may sound small to some miners it can be real time consuming when managing multiple rigs, especially when trying to overclock and change out mining software.
As for Linux based mining operating systems, it appears 2 to 4GB is optimal but I again I say get the 4GB.
So as it stands for max performance 8GB on Win10 and 4GB on Linux and 4GB on Win 10 and 2GB on Linux for those who wish to risk it in hopes to save on costs is what it all boils down to. However, it's not that much more to get the upgraded version in my mind for the added benefits.
On a final note, the one and only time I can think of that RAM can directly affect mining hashrates is in the instance of AMD Vega cards used in mining as they required 8GB to unlock mining optimization features.
DDR3 or DDR4 for Mining.
Again this does not affect the overall hashrate and performance of the mining rig as some might think but it still plays an important role in your mining rigs success. DDR3 and DDR4 refer to the form factor required by your mining rigs motherboard.
Meaning the if your motherboard requires a DDR3 RAM form factor then you will need to buy DDR3 RAM to ensure that it will fit into your motherboards RAM slot.
The one thing I want to add is most newer mining motherboards require a DDR4 form factor size as most were recently designed within the last year or so. However, DDR4 can become out of stock in a hurry from time to time so it's nice to have options like DDR3 as some of the older motherboards still used in mining can fit DDR3.

Best Ram For Mining Rig.
As for some of the best brands of RAM sticks used in mining rigs, there are quite a few decent brands to pick and choose from. Again just make sure you mining rigs motherboard supports the form factor.
Amazon and Newegg are my favorite trusted sources that I will be linking to so be sure look at both options to shop and compare. As for which RAM stick is the best one to get I'm a huge fan of whatever is on sale.
I will tell you that after building and operating hundreds of mining rigs over the last few years I have had the pleasure of trying several different manufacturers just to realize there's not much difference if any at all. I guess, at best, there is the argument that some RAM sticks are more attractive than others but as my old construction boss used to say "we're not building a church".
Really what it boils down to is finding the best deal between Amazon or Newegg to fit your budget needs. With that said the list of best RAM used for mining is as follows.
Crucial has been in the computer part making business for years and is considered a brand of Micron memory. Comes in 4 and 8 GB sizes as well as DDR3 and 4 form factors. Commonly in stock at affordable prices most times making them a favorite in my farm. Although if you're looking for the aesthetically pleasing RAM sticks this might fall under the ugly category, but I don't really care as long it can do the job so to me they're perfect.
G.SKILL is another popular brand that's been around for quite some time now and is another I like to use in my mining rig builds. One thing for sure its alot more esthetically pleasing then Crucial version but again that's not as important as its price. In Addition, it too comes in DDR3 and 4 form factors and 4 to 8 GB versions as well.
Kingston is another popular brand with its hyper fury series making some serious buzz across the mining scene as its affordable and futuristic looking LOL. I must admit they do look cool but I don't use them all that often as their prices were higher back when I needed the parts.
Corsair is a top leader in the computer parts industry and is known for its top-notch durable power supplies when it comes to mining. So its only natural they would have higher end RAM to go with it. Though again it's not necessary unless you're wanting to make your mining rig look cool then the Corsair Vengeance with RGB lighting is the best option. It's also the most expensive so be careful to not go over your budget.
Remember you can use two 4GB sticks to make 8GB total but don't mix one brand or version with another as it can cause major problems with your system performance and even hardware failure.
Other Related Questions.
Does the CPU affect GPU mining? If the miner is only GPU mining then a Celeron or Pentium processors will work just fine. However, if the miner is looking to CPU mine while at the same time GPU mine there could be some bottlenecking issues with lower end CPUs. So its best to decide beforehand.
Does Overclocking Improve Mining? Yes, overclocking can improve the mining performance of your computer's hardware. However, overclocking computer hardware can void any manufacturers warranties you may have had when you purchased the item. Nonetheless, lots of miners have successfully optimized their mining rigs this way so just make sure you're careful in doing so.

Bitcoin mining and Return Of Investment (ROI)
by shiwong.
Helloo hello . today I Will write what I have mind.
Bitcoin mining And Return Of Investment.
ROI. Return Of Investment. This term may be more commonly spoken by the investors, the people who invest some funds (money) to get more profit.
ROI should also be MINDSET in 'industrial Bitcoin'! And unfortunately, this term as a sink for 'bitcoin fever' - people who want to quickly get Bitcoin by doing 'Bitcoin mining' never think long before to spend some money for the purposes of mining that cost is quite expensive.
Bitcoin mining is not a cheap activity. At least you should have a 'special hardware', the cost of internet access and the cost of electricity!
Money you spend for mining purposes - SHOULD - be 'returned' so you do not lose, and the return value should be called so that you can benefit. And this is often forgotten by the patients 'fever bitcoin'.
Take for example:
You buy 100 units of Bitcoin miner USB type because infected 'bitcoin fever'. The manufacturer claims that Bitcoin miner with 100 units you can get 30 million a month (to be online internet 24 hours to 30 days) HOORAY . 30 million a month? Who does not want that much money?
What is the price of Bitcoin miner that USB type per unit? around 1.5 million rupiah per unit! For 100 units means that you have to spend money for .. taraa! 150 Million !!
What are the costs for mining operations. Internet access costs and electricity? For electricity costs need to be considered as per 1 unit USB type Bitcoin miner that require electric power alone .. multiply with many units you have.
Then there is a saying . "Quiet! may be 30 million a month .. six months also had a turnover for the hardware"
One thing that is overlooked is 30 million rupiah per month is not an exact figure! Why?
Factors Bitcoin mining difficulty levels continue to rise. This means that the process of mining will increasingly require the processing power (hash rate) which is greater, if you do not add the hash rate of income Bitcoin mining results will continue to be reduced!
The selling price of Bitcoin is NOT SURE and is more speculative .. today to USD 800 per 1 BTC .. whether it is going to $ 1000 per 1 BTC or even USD 300 per 1 BTC? No one can predict! : P.
So? What they can be sure of at least 150 million spent to buy the hardware Bitcoin Miner was able to return in a short time together with the profit as Return Of Investment? Or do not you do not even think about it at all?
This post is not to prohibit you do Bitcoin mining! Just please note and calculated in detail the pros and cons.
There are many web that can assist you in calculating the expected profits in the process of Bitcoin mining, please use the search keywords' Bitcoin mining Profit Calculator "Please do permutations calculations . you'll find that the actual Bitcoin mining is a business that requires a LOT COST!

In my previous article I presented a method of estimating the break even price of Bitcoin for miners. The reason being that I believe the cost of mining to be a significant factor in determining the underlying stable-value price of Bitcoin. This should help us calculate where the bottom should be in the aftermath of a speculative bubble.
Here I show a simple method for estimating the miner return on investment (ROI) for a given period subject to the applicable state of the art. The ROI should be a ratio, e.g. 10:1, meaning 10 returned for every 1 invested. The break even ratio is of course 1:1.
Obviously the ROI is simply miner revenue (r) divided by hash rate (H) times some conversion factor (alpha). We can use the hash rate and miner revenue (which also includes mining fees) data supplied by blockchain.info. Therefore.
ROI = r / (H * alpha)
alpha is made of two components, one summarizing electricity costs the other mining unit costs.
alpha = alpha_elec + alpha_unit.
Let E_unit = unit efficiency and t_hrs = operating time per day.
In addition, let cost of electricity and unit be C_elec and C_unit respectively.
And let number of units worldwide be N_units.
alpha_elec = E_unit * t_hrs * C_elec.
alpha_unit = N_unit * C_unit / H / 365 days.
Here I spread the cost of unit acquisition/spares/replacements over one year and average. This the cost of unit acquisition per output hash rate. But wait, the number of machines N_unit is actually.
N_unit = H / H_unit,
where H_unit is that hashing power of the mining unit. This means that alpha does not depend on network hash rate and is in fact a true material and energy constant such that.
alpha_unit = C_unit / H_unit / 365 days.
Let's put this together:
= E_unit * t_hrs * C_elec + C_unit / H_unit / 365 days.
Now we just need to divide r/H by alpha to get the miner ROI.
Let's use following data which comes from Bitmain, Blockchain and other sources:
E_unit = 0.1 J/GH = 0.1 kW/TH/s.
C_unit = 800 USD + 100 USD (for PSU)
C_elec = 0.06 USD/kWh (see my previous article on BE price)
H_unit = 13.5 TH/s.
alpha = 0.34 USD/TH/s.
Now we can display the results on the following chart and mark the break even line where ROI = 1:1.
BACK TESTING.
Now let's do the same for 2015 using the then ubiquitous Antminer S5:
E_unit = 0.51 J/GH = 0.51 kW/TH/s.
C_unit = 500 USD + (100 USD for PSU)
C_elec = 0.06 USD/kWh.
H_rate = 0.400 TH/s.
alpha =2.32 USD/TH/s.
A method of estimating the ROI for Bitcoin miners has been shown and applied to the current set of circumstances as well as those prevalent in 2015. In the latter case we see that the market bottoms at the the ROI 1:1 line. In the current case the Bitcoin price is also at the 1:1 line. This could mean we are at or are near to the bottom of the current market correction.
More back testing is required but in the pre-ASIC period, the proliferation of various different GPU and FPGA mining rigs makes even basic statistical analysis difficult.
It is interesting and convenient that the conversion factor does not depend on hashrate. This makes carrying out global comparisons between mining hardware much easier.

When Bitcoin first took off, the concept of mining currency on your computer was pretty foreign to most of us. The idea is that your computer verifies transactions, and in turn you're rewarded with some currency. How many transactions you can verify is directly correctly to how powerful your computer is.
In the early days of cryptocurrencies, even an everyday gaming computer could mine a profitable amount of coin. But, currencies like BitCoin have worked on a sliding scale, meaning it has become more difficult to mine a coin (and the value of the coin has risen). For that reason, mining with a Raspberry Pi has traditionally been counterproductive--it would take you years and years to even make up the cost of the Pi itself.
But, that doesn't mean it's not possible with some currencies. As NovaSpirit proves , a Raspberry Pi 3 can profitably mine Magicoin. There are some tricks to getting the software setup, but he explains how to make it work.
Once it was running, he was able to generate $0.20-$0.25 (USD equivalent) per day. Further, staking with Magicoin means that will eventually start to vest interest which will increase that revenue a bit further. It's worth considering if you've got a spare Raspberry Pi collecting dust between projects.
How to mine bitcoin with your Raspberry Pi.
Bitcoin is big - you probably know that already. Maybe you know someone who has made a bit of money by mining it on their computer. If getting started sounds like a bit of a headache and you're not sure where to start, dig out your Raspberry Pi. You might be surprised, but Raspberry Pi is a tool to use for Bitcoin mining.
Before we go further, let's make sure we understand all of the aspects involved. After all, Raspberry Pi and Bitcoin mining are quite advanced topics and not some technological terms that you read every day. So with that in mind, let's take a quick refresher course.
Okay, so let's start with the easier topic: Raspberry Pi. Basically, Raspberry Pi is a computer with a very, very small size and sold at a very, very low price. Despite the size and the price, Raspberry Pi is a full-fledged computer that you can use like any computer out there, and of course, this includes Bitcoin mining.
There are two ways you can mine Bitcoin. You can either use consumer-grade, general hardware like a CPU to solve calculations, or you can use hardware customized for mining Bitcoin. These are called ASIC miners. These ASIC miners can mine Bitcoin much, much more efficiently than general-purpose hardware. In fact, these days, profitable Bitcoin mining operations can only be done using those ASIC miners.
Since this post is about Bitcoin, we're going to use an ASIC miner for our mining operation. But keep in mind that there are some cryptocurrencies, like Ethereum for example, that you can't mine with an ASIC miner. Since each cryptocurrency is different, it's best to research them separately and not assume that what works with Bitcoin will also work with another cryptocurrency.
Is Raspberry Pi Bitcoin mining profitable?
The bad news is that mining Bitcoin with a Raspberry Pi isn't that profitable. As we've touched upon already, the main expense of mining Bitcoin is the cost of the electricity needed to run the hardware. This means your hardware needs to be efficient enough to earn Bitcoin that exceeds the value of your electricity costs. Unfortunately, your Raspberry Pi isn't powerful enough to deliver this sort of return.
So, why would you even want to start Raspberry Pi Bitcoin mining? Well, for one, it would make a fun side project and you'll learn a lot from doing it. And don't say it too loud, but if you have 'free' electricity (maybe you live in a dorm, for example), that could easily mean earn Bitcoin without spending much at all.
Mining Bitcoin with Raspberry Pi.
Okay, enough talk, let's actually do some mining. To mine Bitcoin with Raspberry Pi, you're going to need:
Raspberry Pi USB Bitcoin ASIC Miner Powered USB Hub.
Having a powered USB Hub is important, because Raspberry Pi can only supply a limited amount of power to a connected USB device. Since a USB ASIC miner can draw a lot of power, using an external power source would solve the power problem. Not to mention that with a USB hub you can connect more than a single ASIC miner to the Raspberry Pi.
There are 2 more things to do before we can start mining. The first one is to set up a Bitcoin wallet, a place to store all the Bitcoin we're going to get. The other one is to join a Bitcoin mining pool. By joining a Bitcoin mining pool, you no longer need to single-handedly finish the entire Bitcoin block calculation to earn Bitcoin. Instead, you can earn Bitcoin by just solving a part of the calculation, since now you are working as a group.
All right, the next thing we want to set up is the mining software. For this one we're going to use BFGMiner, a popular mining software focused on mining with ASIC miner instead of CPU/GPU. To install BFGMiner, you need to install a couple of additional libraries to your Raspberry Pi. You can do this by executing the following commands on the LXTerminal assuming you're using Raspbian operating system:
With the library set up, you can install BFGMiner by executing these lines:
And now, to actually start the mining operation, connect BFGMiner with your mining pool account and run the application. It can be done by running the following command:
And that's it! Now your Raspberry Pi will use the ASIC miner attached to it and automatically mine Bitcoin. The field of cryptocurrency is a vast one, and this little project we've just finished is nothing but a little peek into that field. There are other cryptocurrencies, or other mining methods that you can use to gain profit more effectively.

Bitcoin mining: What is it, Why and How Bitcoins are Mined?
The most popular and demanded cryptocurrency in today's time is bitcoin. Bitcoin first came into existence when an individual named Satoshi Nakamoto created it. Bitcoin is a decentralized digital currency with no physical appearance. Decentralized currency means any financial institution does not control it. The transactions made using bitcoins can never be controlled or governed by a central authority or banks, and the users pay no cost for transactions.
Beginners must know that Bitcoin mining is considered the backbone of the entire bitcoin network. Specialized computers achieve mining, and this is done to provide high security to bitcoins and confirm the bitcoin transactions. The bitcoin miners achieve the mining by solving the complex mathematical problems that further get added to bitcoin transactions.
The main role of miners is to confirm the transactions by securing the bitcoin network. In return, the miners are provided new bitcoins as rewards for solving the block of transactions in every 10 minutes.
What is the actual purpose of Bitcoin mining?
Beginners often get confused about the reason behind mining bitcoins. In this article, we will discuss the functions and aspects of Bitcoin mining. The actual purposes of Bitcoin mining are:
To issue new bitcoins.
Unlike conventional currencies that are issued by banks, the case of bitcoins is a bit different. Bitcoins are not issued or created; the bitcoin miners mine these. The bitcoin miners are the dedicated computers that solve the computation problems. For solving the block of transactions every 10 minutes, miners are rewarded with new bitcoins.
The rate of issuing the bitcoins is automatically set in code; therefore, it doesn't allow the miners to create bitcoins from thin air or cheat the bitcoin system. The new bitcoins can only be generated by using the computing power.
To confirm the transactions.
Every transaction made with bitcoin is added in the blocks. Each transaction is considered completed and secures once it gets added into the block of transactions. Now many people will get confused and may ask why? The answer to your question is that once a transaction gets added into a block, it is officially entrenched in bitcoin's blockchain technology.
To endow with security to the bitcoin network.
The role of miners is to secure the entire bitcoin network and verify the transactions. The miners make it difficult for attackers or hackers to stop, alter, or attack the bitcoin system. The more number of bitcoin miners make the network more secure. For bitcoin trading you can visit bitcoin up app.
Due to bitcoin's volatile market, mining bitcoins are not considered profitable because you are unsure about profit gained from mining at the end of the day. Also, mining bitcoins consume huge electricity that can raise your electricity bills. This is why mining is usually done in big warehouses where the electricity is available at low prices. Let us know the steps included in Bitcoin mining:
To mine the bitcoins, you will get bitcoins as a reward, and these go directly into the bitcoin wallet. Therefore, it is important to have a bitcoin wallet. Select a bitcoin wallet that ensures the safety of bitcoins and offers other great features.
Search a bitcoin exchange.
A bitcoin exchange is a place that exchanges the bitcoins with other currencies when required. After earning the bitcoins, you may have to pay for electricity costs by selling the bitcoins. This process can only be done at a bitcoin exchange.
Find hardware for Bitcoin mining.
It is essential to have an ASIC miner to mine bitcoins. These are the specialized computers that are mainly built to mine bitcoins.
Choose a mining pool.
After finding hardware, it's time to choose a mining pool. Without having a mining pool, the miner may receive the payout for finding the block of transactions on his own, which is referred to as solo mining.
Get the software for Bitcoin mining.
Only through Bitcoin mining software, the miner can fastener their mining hardware to the preferred mining pool. Software is required to point the hash rate at the mining pool.
Make sure Bitcoin mining is legal in your area.
In most countries, Bitcoin mining is legal, but it is better to consult the local counsellors about Bitcoin mining and know about the tax implications.
What is Bitcoin mining, and why is it necessary?
Why does Bitcoin have "Miners?"
Gold has miners because people want gold and it just so happens, unfortunately, that most gold is deep in the earth. Bitcoin has miners because people want bitcoins, but something here seems silly: how did a bunch of bitcoins, the tokens of a man made invention, end up locked up in circumstances demanding mining? What's the point of that?
