Cryptocurrency Miners Explained: Why You Really Dont Want This Junk On Your Pc

Cryptocurrency Miners Explained: Why You Really Don’t Want This Junk on Your PC uTorrent recently made headlines for bundling cryptocurrency-mining junkware. Out of all the junkware programs bundled with installers , cryptocurrency-miners like Epic Scale are some of the worst. Modern malware makes money by using this technique to mine Bitcoin, too. Even if you don’t care about most junkware at all, cryptocurrency-mining software is something you really don’t want on your computer. You’ve probably heard of Bitcoin, the most famous cryptocurrency. It’s a digital currency, and new units of currency are generated by “mining.” This is a computationally intensive task, and it requires a lot of processing power. Essentially, the computer is rewarded for solving difficult math problems. This processing power is used to verify transactions, so all that number-crunching is required for the cryptocurrency to work. That’s an extremely basic explanation — read our in-depth explanation of Bitcoin for more details. Bitcoin isn’t the only cryptocurrency. The Epic Scale junkware bundled with uTorrent’s installer doesn’t attempt to mine Bitcoin — it attempts to mine Litecoin, which was inspired by and is very similar to Bitcoin. How to Remove uTorrent’s EpicScale Crapware From Your Computer Mining programs tap into your computer’s hardware resources and put them to work mining Bitcoin, Litecoin, or another type of cryptocurrency. And no, even if your hardware is used to generate money for them, you don’t get any of it. They get all the money from putting your hardware to work. Worse yet, your desktop computer or laptop at home just isn’t powerful enough to profitably mine Bitcoin, Litecoin, or other cryptocurrencies. Doing this profitably requir Continue reading >>

Mining 101: An Introduction To Cryptocurrency Mining

Mining 101: An Introduction To Cryptocurrency Mining News and reviews from the crossroads of PC gaming & consumer hardware Opinions expressed by Forbes Contributors are their own. Cryptocurrency mining will celebrate its 10th year of existence in 2019. It's certainly no fad, but it's also far from being a popular practice.The very concept of mining with high-endcomputer hardware is starting to trickle into mainstream consciousness, though. If anything, the evidence is in the scarcity of Nvidia and AMD graphics cards and the inflated pricing that has washed through retailers worldwide. The pricing has caught the attention of PC gamers, leaving them puzzled and asking why it's happening. What you may not know is the technology surroundingmining isn't just limited to consumer graphics cards. Were beginning to see PC game platforms that allow you to mine when youre away from your system, and exchange that digital currency for new games. There are even new Pokemon GO-style games hitting the app stores that are outdoor scavenger hunts with cryptocurrency as the ultimate treasure. With that in mind, it seemed like the perfect time to start explaining this craze (I'm going to call it that because it shows no signs of disappearing) to gamers and hardware junkies consideringriding the wave. Its admittedly going to be a challenge! As John Oliver recently exclaimed during HBOs Last Week Tonight, cryptocurrency is: everything you dont understand about money combined with everything you dont understand about computers! You can mine cryptocurrency with your PC, but you can also build specialized mining rigs. So I hope youll stick around for each new guide and explainer.

How To Mine Bitcoin: Here's Everything You Need To Know | Digital Trends

Posted on March 10, 2018 - 9:00AM 3.10.18 - 9:00AM When Bitcoin was first introduced in 2009, mining the worlds first and premier cryptocurrency needed little more than a home PC and not even a fast one at that. Today the barrier for entry is far higher if you want to make any kind of profit doing it. That doesnt mean its impossible, but its not the homebrew industry it once was. Still, if you want to know how to mine Bitcoin, there are a few steps you can take. One involves much more risk and monetary investment than the other, but the potential rewards are greater. So just as when it comes to buying Bitcoin or altcoins , you need to be aware that nothing in the world of cryptocurrencies is guaranteed. Any investment could be lost, so make sure you do your reading before pulling out your credit card. Before we discuss how to mine Bitcoins yourself, its important to note that although there is uncertainty in everything cryptocurrency related, mining is arguably the most volatile. Hardware price fluctuations, changes in Bitcoin difficulty and even the lack of a guarantee of a payout at the end of all your hard work, make it a riskier investment than even buying Bitcoins directly. Nobody can say whether Bitcoins will be worth more tomorrow than they are today, nor can they give you any concrete answer as to whether youll receive a return on your investment, but buying Bitcoin directly at least gives you something for your money immediately. Its certainly worth considering before you go down the mining route. Cloud mining is the practice of renting mining hardware (or a portion of their hashing power) and having someone else do the mining for you. You are typically paid for your investment with Bitcoin. Sometimes even if the hardware isnt used for mining Bitcoin. Although Continue reading >>

Mining - Bitcoin Wiki

Mining is the process of adding transaction records to Bitcoin's public ledger of past transactions (and a " mining rig " is a colloquial metaphor for a single computer system that performs the necessary computations for "mining").This ledger of past transactions is called the block chain as it is a chain of blocks .The block chain serves to confirm transactions to the rest of the network as having taken place.Bitcoin nodes use the block chain to distinguish legitimate Bitcoin transactions from attempts to re-spend coins that have already been spent elsewhere. Mining is intentionally designed to be resource-intensive and difficult so that the number of blocks found each day by miners remains steady. Individual blocks must contain a proof of work to be considered valid. This proof of work is verified by other Bitcoin nodes each time they receive a block. Bitcoin uses the hashcash proof-of-work function. The primary purpose of mining is to allow Bitcoin nodes to reach a secure, tamper-resistant consensus.Mining is also the mechanism used to introduce Bitcoins into the system:Miners are paid any transaction fees as well as a "subsidy" of newly created coins.This both serves the purpose of disseminating new coins in a decentralized manner as well as motivating people to provide security for the system. Bitcoin mining is so called because it resembles the mining of other commodities:it requires exertion and it slowly makes new currency available at a rate that resembles the rate at which commodities like gold are mined from the ground. Mining a block is difficult because the SHA-256 hash of a block's header must be lower than or equal to the target in order for the block to be accepted by the network. This problem can be simplified for explanation purposes: The hash of a bl Continue reading >>

How Does Bitcoin Mining Work?

How Does Bitcoin Mining Work?

By Euny Hong | Updated October 17, 2017 — 3:51 PM EDT Cryptocurrency mining is painstaking, expensive, and only sporadically rewarding. Nonetheless, mining has a magnetic draw for many investors interested in cryptocurrency. This may be because entrepreneurial types see mining as pennies from heaven, like California gold prospectors in 1848. And if you are technologically inclined, why not do it? Well, before you invest the time and equipment, read this explainer to see whether mining is really for you. We will focus primarily on Bitcoin. (Related: How Bitcoin Works  and our helpful infographic,  What is Bitcoin? ) By mining, you can earn cryptocurrency without having to put down money for it. That said, you certainly don't have to be a miner to own crypto.  You can also  buy crypto using fiat currency (USD, EUR, JPY, etc); you can trade it on an exchange like Bitstamp using other crypto (example: Using Ethereum or NEO to buy Bitcoin); you even can earn it by playing video games or by publishing blogposts on platforms that pay its users in crypto. An example of the latter is  Steemit , which is kind of like Medium except that users can reward bloggers by paying them in a proprietary cryptocurrency called Steem.  Steem can then be traded elsewhere for Bitcoin.  In addition to lining the pockets of miners, mining serves a second and vital purpose: It is the only way to release new cryptocurrency into circulation. In other words, miners are basically "minting" currency. For example, as of the time of writing this piece, there were about 16 million Bitcoin in circulation. Aside from the coins minted via the genesis block (the very first block created by Bitcoin founder Satoshi Nakamoto himself), every single one of those Bitcoin came into being because of min Continue reading >>

Bitcoin Mining Definition | Investopedia

Bitcoin Mining Definition | Investopedia

Bitcoin mining is the process by which transactions are verified and added to the public ledger, known as the block chain, and also the means through which new bitcoin are released. Anyone with access to the internet and suitable hardware can participate in mining. The mining process involves compiling recent transactions into blocks and trying to solve a computationally difficult puzzle. The participant who first solves the puzzle gets to place the next block on the block chain and claim the rewards. The rewards, whichincentivize mining, are both the transaction fees associated with the transactions compiled in the block as well as newly released bitcoin. (Related: How Does Bitcoin Mining Work? ) The amount of new bitcoin released with each mined block is called the block reward. The block reward is halved every 210,000 blocks, or roughly every 4 years. The block reward started at 50 in 2009, is now 25 in 2014, and will continue to decrease. This diminishing block reward will result in a total release of bitcoin that approaches 21 million. How hard are the puzzles involved in mining? Well, that depends on how much effort is being put into mining across the network. The difficulty of the mining can be adjusted, and is adjusted by the protocol every 2016 blocks, or roughly every 2 weeks. The difficulty adjusts itself with the aim of keeping the rate of block discovery constant. Thus if more computational power is employed in mining, then the difficulty will adjust upwards to make mining harder. And if computational power is taken off of the network, the opposite happens. The difficulty adjusts downward to make mining easier. In the earliest days of Bitcoin, mining was done with CPUs from normal desktop computers. Graphics cards, or graphics processing units (GPUs), are Continue reading >>

Cryptocurrency Mining: What It Is, How It Works And Who's Making Money Off It

Cryptocurrency Mining: What It Is, How It Works And Who's Making Money Off It Shanthi Rexaline , Benzinga Staff Writer   NVIDIA Corporation (NASDAQ: NVDA )'s second-quarter earnings released earlier this month, though exceeding expectations, elicited cautionary reaction from the investor as well as analyst communities. Traders bid down the stock by over 5 percent on Aug. 11. One of the reasons cited for the negative reaction was cryptocurrency contributing to much of the outperformance. Start mining crypto currencies with HashFlare . Analysts Blayne Curtis and Christopher Hemmelgarn of Barclays believes revenue stream from cryptocurrency is fickle. Therefore, the analysts were not in favor of assigning a multiple to it, as it has the potential to become an eventual headwind. Rival Advanced Micro Devices, Inc. (NASDAQ: AMD ) also had a similar tale to tell. The company indicated that cryptocurrency demand remains strong, while also suggesting that the demand might not last forever. Cryptocurrency, as the name suggests, is a form of digital money designed to be secure and anonymous in most cases. It uses a technique called cryptography — a process used to convert legible information into an almost uncrackable code, to help track purchases and transfers. Giving a simple definition, Blockgeeks says it is just limited entries in a database no one can change without fulfilling specific conditions. Cryptography is a technique that uses elements of mathematical theory and computer science and was evolved during the World War II to securely transfer data and information. Currently, it is used to secure communications, information and money online. Cryptocurrencies allow users to make secure payments, without having to go through banks. Some cryptocurrencies include bitcoin, Continue reading >>

How Bitcoin Mining Works - Coindesk

In traditional fiat money systems, governments simply print more money when they need to. But in bitcoin, money isn’t printed at all – it is discovered. Computers around the world ‘mine’ for coins by competing with each other. People are sending bitcoins to each other over the bitcoin network all the time, but unless someone keeps a record of all these transactions, no-one would be able to keep track of who had paid what. The bitcoin network deals with this by collecting all of the transactions made during a set period into a list, called a block. It’s the miners’ job to confirm those transactions, and write them into a general ledger. This general ledger is a long list of blocks, known as the 'blockchain'. It can be used to explore any transaction made between any bitcoin addresses, at any point on the network. Whenever a new block of transactions is created, it is added to the blockchain, creating an increasingly lengthy list of all the transactions that ever took place on the bitcoin network. A constantly updated copy of the block is given to everyone who participates, so that they know what is going on. But a general ledger has to be trusted, and all of this is held digitally. How can we be sure that the blockchain stays intact, and is never tampered with? This is where the miners come in. When a block of transactions is created, miners put it through a process. They take the information in the block, and apply a mathematical formula to it, turning it into something else. That something else is a far shorter, seemingly random sequence of letters and numbers known as a hash. This hash is stored along with the block, at the end of the blockchain at that point in time. Hashes have some interesting properties. It’s easy to produce a hash from a collection Continue reading >>

What Is Cryptocurrency Mining?

What Is Cryptocurrency Mining?

Ever wondered how bitcoins are actually made? Over the past several years, cryptocurrencies like Bitcoin have been quietly growing in popularity, with an ever-larger number of people buying and selling them. Now that Bitcoin has hit the mainstream and become a worldwide phenomenon, more people than ever are looking to get into the cryptocurrency game. However, the production of cryptocurrencies isn't anything like that of regular money. There's no central authority that issues new notes; instead, bitcoins (or litecoins, or any of the other so-called 'alt-coins') are generated through a process known as 'mining'. So what is cryptocurrency mining, and how does it work? Before getting to grips with the process of cryptocurrency mining, we need to explain what blockchain is and how that works. Blockchain is a technology that supports almost every cryptocurrency. It is a public ledger (decentralised register) of every transaction that has been carried out in that cryptocurrency. These transactions are assembled into what are called "blocks". These are the verified to ensure they are legitimate by cryptocurrency miners. This checks if the same coin hasn't been expended again before the transaction has cleared, and that the input and output expenses tally. Then the next sequential transaction block is connected to it. This is how cryptocurrencies are created and how new cryptocoins are made. As there is no central authority or central bank, there has to be a way of gathering every transaction carried out with a cryptocurrency in order to create a new block. Network nodes that carry out this task called dubbed 'miners'. Every time a slew of transactions is amassed into a block, this is appended to the blockchain. Whoever appends the block gets rewarded with some of that crypto Continue reading >>

What Is Cryptocurrency Mining? Webopedia Definition

Cryptocurrency mining, or cryptomining, is a process in which transactions for various forms of cryptocurrency are verified and added to the blockchain digital ledger. Also known as cryptocoin mining, altcoin mining, or Bitcoin mining (for the most popular form of cryptocurrency, Bitcoin), cryptocurrency mining has increased both as a topic and activity as cryptocurrency usage itself has grown exponentially in the last few years. Each time a cryptocurrency transaction is made, a cryptocurrency miner is responsible for ensuring the authenticity of information and updating the blockchain with the transaction. The mining process itself involves competing with other cryptominers to solve complicated mathematical problems with cryptographic hash functions that are associated with a block containing the transaction data. The first cryptocurrency miner to crack the code is rewarded by being able to authorize the transaction, and in return for the service provided, cryptominers earn small amounts of cryptocurrency of their own. In order to be competitive with other cryptominers, though, a cryptocurrency miner needs a computer with specialized hardware. How to Get Started as a Cryptocurrency Miner While cryptomining can generate a small income for a cryptocurrency miner, in most cases only in the amount of a dollar or two per day for an individual using their own dedicated computer hardware . Expenses like electricity, internet connection, and computing hardware also impact the net revenue generated by cryptocurrency mining. In order to get started mining, cryptocurrency miners will need dedicated computer hardware with a specialized graphical processing unit (GPU) chip or application-specific integrated circuit (ASIC), sufficient cooling means for the hardware, an always-on in Continue reading >>

Last year’s Ethereum blockchain split was an event that could have resulted in significant loss and with the 1st August Bitcoin Fork event just around the corner, a greater knowledge of the process and the risks is certainly relevant as cryptocurrency demand continues to build. While many have looked at simply trading cryptocurrencies such as Bitcoin , others have gone into the mining, which is the process through which coins are created. For want to be miners, appropriate hardware and access to the internet is needed for an investor to mine, the actual process being the compilation of recent transactions into blocks in order to solve complex puzzles. The person who solves the puzzle first is permitted to place the next block on the blockchain and reap the rewards, which include transaction fees associated with the transactions carried out in the block, together with a newly released Continue reading >>

HitBTC cryptocurrency exchange terminal window A cryptocurrency (or crypto currency) is a digital asset designed to work as a medium of exchange using cryptography to secure the transactions, to control the creation of additional units, and to verify the transfer of assets. [1] [2] [3] Cryptocurrencies are classified as a subset of digital currencies and are also classified as a subset of alternative currencies and virtual currencies . Bitcoin , created in 2009, was the first decentralized cryptocurrency. [4] Since then, numerous cryptocurrencies have been created. [5] These are frequently called altcoins, as a blend of bitcoin alternative. [6] [7] [8] Bitcoin and its derivatives use decentralized control [9] as opposed to centralized electronic money / central banking systems. [10] The decentralized control is related to the use of bitcoin's blockchain transaction database in the role of a distributed ledger . [11] Decentralized cryptocurrency is produced by the entire cryptocurrency system collectively, at a rate which is defined when the system is created and which is publicly known. In centralized banking and economic systems such as the Federal Reserve System , corporate boards or governments control the supply of currency by printing units of fiat money or demanding additions to digital banking ledgers. In case of decentralized cryptocurrency, companies or governments cannot produce new units, and have not so far provided backing for other firms, banks or corporate entities which hold asset value measured in it. The underlying technical system upon which decentralized cryptocurrencies are based was created by the group or individual known as Satoshi Nakamoto .

A Beginner's Guide To Cryptocoin Mining

A Beginner's Guide To Cryptocoin Mining

Is it worth your time to mine for cryptocoins? Cryptocurrency mining takes patience and time. Koron/Moment/Getty Images Mining cryptocoins  is an arms race that rewards early adopters. You might have heard of Bitcoin , the first decentralized cryptocurrency that was released in early 2009. Similar digital currencies have crept into the worldwide market since then, including a spin-off from Bitcoin called Bitcoin Cash . You can get in on the cryptocurrency rush if you take the time to learn the basics properly. If you had started mining Bitcoins back in 2009, you could have earned thousands of dollars by now. At the same time, there are plenty of  ways you could have lost money , too.  Bitcoins  are not a good choice for beginning miners who work on a small scale. The current up-front investment and maintenance costs, not to mention the sheer mathematical difficulty of the process, just doesn't make it profitable for consumer-level hardware. Now, Bitcoin mining is reserved for large-scale operations only.   Litecoins , Dogecoins, and Feathercoins , on the other hand, are three Scrypt-based cryptocurrencies that are the best cost-benefit for beginners. At the current value of Litecoin, a person might earn anywhere from 50 cents to 10 dollars per day using consumer level mining hardware. Dogecoins and Feathercoins would yield slightly less profit with the same mining hardware but are becoming more popular daily. Peercoins , too, can also be a reasonably decent return on your investment of time and energy. As more people join the cryptocoin rush, your choice could get more difficult to mine because more expensive hardware will be required to to discover coins. You will be forced to either invest heavily if you want to stay mining that coin, or you will want to Continue reading >>

Cryptomining Is Surprisingly Easy, But I'm Still 8 Months From Breaking Even - Business Insider

Registration on or use of this site constitutes acceptance of our For two years, I owned a cryptomining machine and didn't even know it. I have two of the most powerful graphics cards you can buy: the GTX 1080, which I then upgraded to the GTX 1080 Ti. And they just so happen to be some of the best graphics cards for mining cryptocurrencies. Cryptomining is the process of solving complex problems to verify digital transactions using computer hardware — in this case, a graphics card. Miners can either create a cryptocurrency or get paid for their processing power in a cryptocurrency. Those graphics cards cost me a pretty penny, even if I bought them before the massive graphics-card price hikes caused by cryptominers buying them up . And when I wasn't gaming, my GTX 1080 and GTX 1080 Ti just lay there, doing nothing, not making me money. No more. One day, I decided to try mining cryptocurrency with them. I was making some profit at first, but not very much. So I got curious. What if I added more graphics cards? How much could I make? Check out my new messy mining-rig experiment to see how much in bitcoin I'm making. Why not just buy cryptocurrency instead of mining it? I could just buy cryptocurrencies instead of mining. But that means I'd be paying for it. My goal here is to amass as much bitcoin as possible for less than I can buy it at market price — within my means, of course. And if I'm making a profit, even if it's not exactly huge, why not? Just so long as it covers the cost of the electricity it uses, as well as the extra parts I bought for the experiment. The moment mining becomes more expensive than buying the cryptocurrency, I'll stop. W Continue reading >>

Everything You Need To Know About Bitcoin Mining

Everything You Need To Know About Bitcoin Mining

Where do bitcoins come from? With paper money, a government decides when to print and distribute money. Bitcoin doesn't have a central government. With Bitcoin, miners use special software to solve math problems and are issued a certain number of bitcoins in exchange. This provides a smart way to issue the currency and also creates an incentive for more people to mine. Bitcoin miners help keep the Bitcoin network secure by approving transactions. Mining is an important and integral part of Bitcoin that ensures fairness while keeping the Bitcoin network stable, safe and secure. Bitcoin mining is the process of adding transaction records to Bitcoin's public ledger of past transactions or blockchain. This ledger of past transactions is called the block chain as it is a chain of blocks. The block chain serves to confirm transactions to the rest of the network as having taken place.
