Bitcoin (btc) Mining: Huge Energy Reserves Needed To Mine Cryptocurrency Are Here To Stay Quartz

Michel Rauchs Lead in Cryptocurrency and Blockchain, Cambridge Centre for Alternative Finance, Cambridge Judge Business School Iceland will use more electricity mining bitcoins than powering its homes in 2018. (Reuters/Jemima Kelly) Michel Rauchs Lead in Cryptocurrency and Blockchain, Cambridge Centre for Alternative Finance, Cambridge Judge Business School The enormous use of energy needed to mine bitcoin and other cryptocurrencies is proving to be very contentious, but alternative methods pose far too much of a security risk. The recent warning that electricity use at bitcoin mining facilities in Iceland may exceed that consumed annually by the countrys homes, which could in turn lead to a potential energy shortage, was slightly alarmist in tone. But it showcases the huge amount of computational power needed to mine cryptocurrencies. Is the current cryptocurrency mining process really as wasteful and useless as critics say , and is it in need of a more efficient and cleaner system? The current mining process is indeed resource-intensive and wasteful, but there is no magic fix in sight. Many would argue that its precisely the useless nature of cryptocurrency mining that keeps the system secure. Cryptocurrencies are based on a globally distributed ledger shared among all participants in a decentralized network. This ledger is generally organiZed in the form of a cumbersome data structurethe blockchain which consists of blocks of transactions that are cryptographically linked to each other. Most cryptocurrencies use a particular mechanism, dubbed proof-of-work (PoW), to determine which participant gets the right to add a new block of transactions to the blockchain. To prevent dishonest participants from creating multiple identities to manipulate the public vote, PoW req Continue reading >>

Want To Make Money Mining Bitcoins? Criminals Have You Beat

Want to make money mining bitcoins? Criminals have you beat Bitcoins are becoming the "national currency" of criminals the world over and are becoming an increasingly poor investment for legitimate miners. Bitcoin is an interesting beast. It seems like something out of a William Gibson cyberpunk novel.It was created by a shadowy figure that could be an individual or a cartel. It's infinitely traceable but ownership is completely anonymous. It has value; at the moment I write this, each "coin" is worth $869.61 and the total dollar value of existing bitcoins worldwide is almost $11 billion. Unlike traditional currency , it exists outside of national control. Like precious metals, it can be mined, but unlike precious metals, you can't hold it in your hand. It's real, in that some merchants and services will accept bitcoin as payment. It's virtual, in that it exists only as a series of entries in a global data structure. And it's become the new best friend of criminals the world over . You can gain ownership of bitcoin in three primary ways: you can buy them, you can get paid in them in return for a product or service, or you can make them through a process called bitcoin mining. The first two approaches: buying bitcoin and getting paid in bitcoin are interesting, in that any item that can be bought and sold is interesting. Bitcoins might be, to quote Paul Krugma n, storehouses of value, or they could someday go "poof" and simply be bits worth less than two bits. The bitcoin system is set up to limit the total number of bitcoins that will ever be available in the world pool. That limit in total availability artificially forces value on each coin because the resource is designed to have scarcity built into its DNA. What's propping up the value of bitcoin is both buzz and th Continue reading >>

Beginner's Guide To Mining Bitcoins

Beginner's Guide To Mining Bitcoins

Last updated on October 13th, 2017 at 10:56 pm One of the biggest problems I ran into when I was looking to start mining Bitcoin for investment and profit was most of the sites were written for the advanced user. I am not a professional coder, I have no experience with Ubuntu, Linux and minimal experience with Mac. So, this is for the individual or group that wants to get started the easy way. Bitcoin mining is a very competitive niche to get into. As more and more miners come on board with the latest mining hardware the difficulty to mine increases each day. Before even starting out with Bitcoin mining you need to do your due diligence. This means you need to find out if Bitcoin mining is even profitable for you . The best way to do this is through the use of a Bitcoin mining calculator . Just enter the data of the Bitcoin miner you are planning on buying and see how long it will take you to break even or make a profit. However, I can tell you from the get go that if you dont have a few hundred dollars to spare you probably wont be able to mine any Bitcoins. Once youve finished with your calculations its time to get yourminer. Make sure to go over our different Bitcoin mining hardware reviews to understand which miner is best for you. Today, the Antminer S9 is the newest and most powerful miner. As a side note its important to state that in the past it was possible to mine Bitcoins with your computer or with a graphics card (also known as GPU mining). Today however, the mining niche has become so competitive that youll need to use ASIC miners special computers built strictly for mining Bitcoins. First thing you need to do is get a Bitcoin Wallet . Because Bitcoin is an internet based currency, you need a place to keep your Bitcoins.Once you have a wallet make sure to Continue reading >>

Cnbc Explains: How To Mine Bitcoins On Your Own

Cnbc Explains: How To Mine Bitcoins On Your Own

CNBC Explains: How to mine bitcoins on your own Bitcoins act like cash, but they are mined like gold. So how does someone get into the current bitcoin rush? If properly done and willing to take the investment risk, you could wind up with a few bitcoins of your ownwhich currently have an average weekly price of $945 on the largest bitcoin exchange. When the algorithm was created under the pseudonym Satoshi Nakamotowhich in Japanese is as common a name as Steve Smiththe individual(s) set a finite limit on the number of bitcoins that will ever exist: 21 million. Currently, more than 12 million are in circulation. That means that a little less than 9 million bitcoins are waiting to be discovered. Since 2009, the number of bitcoins mined has skyrocketed. That's the way the system was set upeasy to mine in the beginning, and harder as we approach that 21 millionth bitcoin. At the current rate of creation, the final bitcoin will be mined in the year 2140. There are three primary ways to obtain bitcoins: buying on an exchange, accepting them for goods and services, and mining new ones. "Mining" is lingo for the discovery of new bitcoinsjust like finding gold. In reality, it's simply the verification of bitcoin transactions. For example, Eric buys a TV from Nicole with a bitcoin. In order to make sure his bitcoin is a genuine bitcoin, miners begin to verify the transaction. It's not just one transaction individuals are trying to verify; it's many. All the transactions are gathered into boxes with a virtual padlock on themcalled "block chains." Miners run software to find the key that will open that padlock. Once their computer finds it, the box pops open and the transactions are verified. For finding that "needle in a haystack" key, the miner gets a reward of 25 newly generated Continue reading >>

Heres How Much It Costs To Mine A Single Bitcoin In Your Country

Heres how much it costs to mine a single bitcoin in your country Looking to mine bitcoin on the cheap? Head to Venezuela So-called bitcoin mining is a hot topic of in the cryptocurrency world. Thats chiefly because of the rising electricity costs associated with creating new digital coins. Lately, miners have flocked to Iceland, known for its relatively moderate climate and the abundance of hydropower. In fact, bitcoin mining energy consumption is set to exceed private consumption, an energy expert told the BBC . And according to the Bitcoin Energy Consumption Index , global energy usage of all bitcoin mining already is equivalent to the power uptake of the country of Denmark, with a population of 5.7 million, and will eventually approach Bangladesh, a country of 163 million people. In search of cost savings, cryptocurrency miners traverse the globe to take advantage of cheaper energy. Those virtual miners perform a crucial function within the blockchain, or the decentralized ledger technology that underpins most cryptocurrencies, by solving complex problems to validate transactions on the network, In exchange for this function, which powers miners are rewarded with bitcoins. However, because bitcoins protocol operates on a proof-of-work basismeaning it requires an expenditure of computing powerboth the power and difficulty of problems increase as miners approach the maximum number of bitcoins meant to exist at 21 million. Currently, there are about 16.9 million bitcoins in existence. The mainstream attention around bitcoin as it hit a peak level at $20,000 last December has led to an outcropping of digital miners and mining operations. So, where is the cheapest place to mine bitcoin? According to research conducted by Elite Fixtures , the cost of mining a bitcoin vari Continue reading >>

How To Mine Bitcoins: 8 Steps (with Pictures) - Wikihow

How To Mine Bitcoins: 8 Steps (with Pictures) - Wikihow

So you've heard of Bitcoin, and you're ready to get your hands on some digital wealth. You can buy and trade for bitcoins, or you can "mine" for them. Mining for bitcoins is actually the process of verifying other bitcoin transactions, which users are rewarded for. This is the central mechanic behind the bitcoin economy, and mining is used to keep transactions secure and reliable. This guide will explain how to mine bitcoins and potentially earn a fair amount of money. Purchase custom mining hardware. When Bitcoin first started, it was possible to mine using only your desktop's CPU and GPU. While this is still possible, the returns make running this method impractical. You will be spending far more on electricity than you will earn mining coins. Instead, custom hardware allows for much better processing for about the same power draw. Custom hardware comes in the form of cards that are inserted into the computer much the same way that a graphics card would be . Popular Bitcoin-mining hardware brands include Butterfly Labs, Bitcoin Ultra, CoinTerra, and more. A dedicated Bitcoin mining machine can cost anywhere from a few hundred dollars to tens of thousands depending on the number of operations it can complete per second. Obtain a bitcoin wallet. Bitcoins are stored in digital wallets that are encrypted to protect your money. These wallets can be either locally or online . While online services that host your wallet won't be able to access it, they are considered less secure as your money could potentially be lost if something catastrophic happens on their end. Most established bitcoin users recommend using a local wallet for security reasons. Local wallets typically require verifying the entire blockchain, which is the history of all bitcoin transactions. Hosting a blo Continue reading >>

How To Set Up A Bitcoin Miner - Coindesk

How To Set Up A Bitcoin Miner - Coindesk

There are three main categories of bitcoin mining hardware, each more expensive and more powerful than the last. This guide to setting up a bitcoin miner explains each of them, and talks about how to make them work. By this stage, you will understand how bitcoin works , and what mining means. But we need to get from theory to practice. How can you set up a bitcoin mining hardware and start generating some digital cash? The first thing you're going to need to do is decide on your hardware, and there are two main things to think about when choosing it: This is the number of calculations that your hardware can perform every second as it tries to crack the mathematical problem we described in our mining section. Hash rates are measured in megahashes, gigahashes, and terahashes per second (MH/sec, GH/sec, and TH/sec. The higher your hash rate (compared to the current average hash rate), the more likely you are to solve a transaction block. The bitcoin wikis mining hardware comparison page is a good place to go for rough information on hash rates for different hardware. All this computing power chews up electricity, and that costs money. It's worth looking at your hardware's energy consumption in watts, when making your choice. You want to make sure that you don't end up spending all of your money on electricity to mine coins that won't be worth what you paid. Use these two factors to work out how many hashes youre getting for every watt of electricity that you use. To do this, divide the hash count by the number of watts. For example, if you have a 500 GH/sec device, and its taking 400 watts of power, then youre getting 1.25 GH/sec per watt. You can check your power bill or use an electricity price calculator online to find out how much that means in hard cash. However, the Continue reading >>

PCMag reviews products independently , but we may earn affiliate commissions from buying links on this page. Terms of use . My cousin has always been one for cockamamie get-rich-quick schemes. This time, he's finally on to something: Bitcoin mining. Over the holidays, after a family dinner at his parents' house on Long Island, my cousin invited me downstairs to show me his latest big idea. In the basement, I came face-to-face with whirring machines, Ethernet cables, power adapters, and exhaust tubes snaking around the room. All of this, he explained, comprised one Bitcoin node and two Litecoin nodes. My cousin's new DIY cryptocurrency mining operation was booming. Bitcoin and other cryptocurrencies such as Ether, Litecoin, and Ripple have exploded into the mainstream over the past year. Skyrocketing prices have stoked an ongoing craze to get in on the action. Most casual traders are happy with simply buying and selling coins using exchanges and storing their cryptocurrency using wallet apps. But those looking to dig deeper (sorry) and willing to lay out some capital can invest in the hardware, software, and shared ecosystem to actually mine cryptocurrencies like Bitcoin. I've written a lot about blockchain , so I was fully aware of the compute power needed to mine cryptocurrency (more on that below). That night, though, was my first time seeing an active Bitcoin mining rig up close. "Did you learn how to code?" I asked him. Nope, he replied; he bought the preconfigured mining hardware online and has been learning the rest as he goes along. Cryptocurrency mining is not simple, nor is it cheap to get up and running. But if you're looking for a source of stead Continue reading >>

Getting Started With Bitcoin Mining

Getting Started With Bitcoin Mining

You will learn (1) how bitcoin mining works, (2) how to start mining bitcoins, (3) what the best bitcoin mining software is, (4) what the best bitcoin mining hardware is, (5) where to find the best bitcoin mining pools and (6) how to optimize your bitcoin earnings. Bitcoin mining is difficult to do profitably but if you try then this Bitcoin miner is probably a good shot. Before you start mining Bitcoin, it's useful to understand what Bitcoin mining really means. Bitcoin mining is legal and is accomplished by running SHA256 double round hash verification processes in order to validate Bitcoin transactions and provide the requisite security for the public ledger of the Bitcoin network. The speed at which you mine Bitcoins is measured in hashes per second. The Bitcoin network compensates Bitcoin miners for their effort by releasing bitcoin to those who contribute the needed computational power. This comes in the form of both newly issued bitcoins and from the transaction fees included in the transactions validated when mining bitcoins. The more computing power you contribute then the greater your share of the reward. Step 1 - Get The Best Bitcoin Mining Hardware Purchasing Bitcoins - In some cases, you may need to purchase mining hardware with bitcoins. Today, you can purchase most hardware on Amazon . You also may want to check the bitcoin charts . To begin mining bitcoins , you'll need to acquire bitcoin mining hardware. In the early days of bitcoin, it was possible to mine with your computer CPU or high speed video processor card. Today that's no longer possible. Custom Bitcoin ASIC chips offer performance up to 100x the capability of older systems have come to dominate the Bitcoin mining industry. Bitcoin mining with anything less will consume more in electricity tha Continue reading >>

You might think you need an extreme know-how of computers to do any kind of crypto mining, that it couldn't possibly be done by the average person. You just need computer parts that are powerful enough to make mining profitable, and a handy piece of software called Nicehash. You literally press a green button on Nicehash to start mining. I've been experimenting with crypto mining on Nicehash myself, and it's been a fun little project. I'm not raking in a huge amount of cash, as my mining rig is small enough that it's more like looking for change on a sidewalk. Bigger mining organizations have warehouses full of powerful computer parts that can generate a ton of cryptocurrencies. And at the end of the day, I'd only really suggest it if you already have a gaming PC with an appropriately powerful graphics card - the key component for mining. And you need to make sure your electricity costs aren't too high, as mining can suck up a ton of energy. Before anything, you have to make sure you have the right gear. Whether or not you know anything about mining, you need to have some powerful hardware. You could mine with a basic computer that only has a processor, like an Intel or AMD processor. But graphics cards that PC gamers use to power their games are much better suited for the job. For the best results, you'll need desktop PC and Nvidia or AMD graphics cards.

How Bitcoin Mining Works - The Economist Explains

How Bitcoin Mining Works - The Economist Explains

AS THE bitcoin price continues to fall, sceptics have started to wonder what will happen to the industry underpinning this digital “crypto-currency” . Around the world, hundreds of thousands of specialised computers have been built to create (or “mine”) bitcoins and, in the process, validate transactions and protect the system. How does bitcoin mining work? The aim of bitcoin—as envisaged by Satoshi Nakamoto, its elusive creator—is to provide a way to exchange tokens of value online without having to rely on centralised intermediaries, such as banks. Instead the necessary record-keeping is decentralised into a “blockchain”, an ever-expanding ledger that holds the transaction history of all bitcoins in circulation, and lives on the thousands of machines on the bitcoin network. But if there is no central authority, who decides which transactions are valid and should be added to the blockchain? And how is it possible to ensure that the system cannot be gamed, for example by spending the same bitcoin twice? The answer is mining. Every ten minutes or so mining computers collect a few hundred pending bitcoin transactions (a “block”) and turn them into a mathematical puzzle. The first miner to find the solution announces it to others on the network. The other miners then check whether the sender of the funds has the right to spend the money, and whether the solution to the puzzle is correct. If enough of them grant their approval, the block is cryptographically added to the ledger and the miners move on to the next set of transactions (hence the term “blockchain”). The miner who found the solution gets 25 bitcoins as a reward, but only after another 99 blocks have been added to the ledger. All this gives miners an incentive to participate in the syste Continue reading >>

How To Get Started With Bitcoin Mining.

Before you read further, please understand that most bitcoin users don't mine! But if you do then this Bitcoin miner is probably the best deal. Bitcoin mining for profit is very competitive and volatility in the Bitcoin price makes it difficult to realize monetary gains without also speculating on the price. Mining makes sense if you plan to do it for fun, to learn or to support the security of Bitcoin and do not care if you make a profit. If you have access to large amounts of cheap electricity and the ability to manage a large installation and business, you can mine for a profit. If you want to get bitcoins based on a fixed amount of mining power, but you don't want to run the actual hardware yourself, you can purchase a mining contract. Another tool many people like to buy is a Bitcoin debit card which enables people to load a debit card with funds via bitcoins. Bitcoin mining is a lot like a giant lottery where you compete with your mining hardware with everyone on the network to earn bitcoins. Faster Bitcoin mining hardware is able to attempt more tries per second to win this lottery while the Bitcoin network itself adjusts roughly every two weeks to keep the rate of finding a winning block hash to every ten minutes. In the big picture, Bitcoin mining secures transactions that are recorded in Bitcon's public ledger, the block chain. By conducting a random lottery where electricity and specialized equipment are the price of admission, the cost to disrupt the Bitcoin network scales with the amount of hashing power that is being spent by all mining participants. During mining, your Bitcoin mining hardware runs a cryptographic hashing function (two rounds of SHA256) on what is called a block header . For each new hash that is tried, the mining software will use a diff Continue reading >>

Bitcoin Mining: What To Buy, How To Mine, And Is It Worth It?

Bitcoin Mining: What To Buy, How To Mine, And Is It Worth It?

In the last 12 months, the value of bitcoin has gone from $1,000 per coin to almost $20,000. Despite a turbulent 2017, the cryptocurrency's price is expected to rocket upwards through 2018 and beyond. To many, bitcoin remains an attractive if incredible volatile investment. But buying bitcoins and hoping their price will go up is just one side of the story. The other is mining, or creating of new bitcoins. While there is a finite number of bitcoin 21 million the computer-powered process to uncover them will continue until the final bitcoin is mined, expected around the year 2140. To date, about 16.8 million bitcoins exist with roughly 1,800 generated each day . In other words: there's still time to get in on the frenzy if you wish. Every bitcoin transaction that occurs between one user and another must be authorized before added to the blockchain, a public ledger or record of all bitcoin transactions ever made since the currency was created in 2008. Transactions are authorized by computers connected to the blockchain, completing incredibly complicated equations. These calculations aren't just complex for a human, they are phenomenally complicated, even for a powerful computer, and the difficultly keeps increasing as more bitcoins are produced. Computers which successfully authenticate these transactions are rewarded with a block of new bitcoins. The number of bitcoins per block started at 50, but this halves for every 210,000 mined blocks that are recorded anywhere. The reward for each block is now 12.5 bitcoins. This will half to 6.25 bitcoins around June 2020. In short, the reward for mining is falling in terms of how many bitcoins (or fractions of a bitcoin) you might receive. The converse is the value of each bitcoin is rising, and sometimes dramatically so. Much l Continue reading >>

If you clicked the button above, then you are currently mining bitcoin, the math-based digital currency that recently topped $1,000 on exchanges. Congratulations. (It wont do anything bad to your computer, we promise.) New bitcoins are created roughly every 10 minutes in batches of 25 coins, with each coin worth around $730 at current rates. Your computerin collaboration with those of everyone else reading this post who clicked the button aboveis racing thousands of others to unlock and claim the next batch. For as long as that counter above keeps climbing, your computer will keep running a bitcoin mining script and trying to get a piece of the action. (But dont worry: Its designed to shut off after 10 minutes if you are on a phone or a tablet, so your battery doesnt drain). Lets start with what its not doing. Your computer is not blasting through the cavernous depths of the internet in search of digital ore that can be fashioned into bitcoin bullion. There is no ore, and bitcoin mining doesnt involve extracting or smelting anything. Its called mining only because the people who do it are the ones who get new bitcoins, and because bitcoin is a finite resource liberated in small amounts over time, like gold, or anything else that is mined. (The size of each batch of coins drops by half roughly every four years, and around 2140, it will be cut to zero, capping the total number of bitcoins in circulation at 21 million.) But the analogy ends there. What bitcoin miners actually do could be better described as competitive bookkeeping. Miners build and maintain a gigantic public ledger containing a record of every bitcoin transaction in history. Every time somebody wants to send bitcoins to somebody else, the transfer has to be validated by miners: They check the ledger to ma 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 >>
