Not all user-driven mining is bad either
Far less glamorous but equally uncertain, bitcoin mining is performed by high-powered computers that solve complex computational math problems that is, so complex that they cannot be solved by hand, and indeed complicated enough to tax even incredibly powerful computers. The luck and work required by a computer to solve one of these problems is the equivalent of a miner striking gold in the ground — while digging in a sandbox.
At the time of writing, the chance of a computer solving one of these problems is about 1 in 13 trillion, but more on that later. First, when computers solve these complex math problems on the Bitcoin network, they produce new bitcoin when referring to the individual coins themselves, "bitcoin" typically appears without capitalization , not unlike when a mining operation extracts gold from the ground.
And second, by solving computational math problems, bitcoin miners make the Bitcoin payment network trustworthy and secure, by verifying its transaction information. Consumers tend to trust printed currencies, at least in the United States. In addition to a host of other responsibilities, the Federal Reserve regulates the production of new money, and the federal government prosecutes the use of counterfeit currency. Even digital payments using the U. When you make an online purchase using your debit or credit card, for example, that transaction is processed by a payment processing company such as Mastercard or Visa.
In addition to recording your transaction history, those companies verify that transactions are not fraudulent, which is one reason your debit or credit card may be suspended while traveling. Bitcoin, on the other hand, is not regulated by a central authority.
Nodes store information about prior transactions and help to verify their authenticity. Unlike those central authorities, however, Bitcoin nodes are spread out across the world and record transaction data in a public list that can be accessed by anyone, even you.
When bitcoin miners add a new block of transactions to the blockchain, part of their job is to make sure that those transactions are accurate.
More on the magic of how this happens in a second. With digital currency, however, it's a different story. Digital information can be reproduced relatively easily, so with Bitcoin and other digital currencies, there is a risk that a spender can make a copy of their bitcoin and send it to another party while still holding onto the original. If the numbers were identical, the clerk would know the money had been duplicated. This analogy is similar to what a bitcoin miner does when they verify new transactions.
With as many as , purchases and sales occurring in a single day, however, verifying each of those transactions can be a lot of work for miners, which gets at one other key difference between bitcoin miners and the Federal Reserve, Mastercard or Visa.
As compensation for their efforts, miners are awarded bitcoin whenever they add a new block of transactions to the blockchain. The amount of new bitcoin released with each mined block is called the "block reward. In , it was In , it was 25, in it was At this rate of halving, the total number of bitcoin in circulation will approach a limit of 21 million, making the currency more scarce and valuable over time but also more costly for miners to produce.
Here's the catch. In order for bitcoin miners to actually earn bitcoin from verifying transactions, two things have to occur. First, they must verify 1 megabyte MB worth of transactions, which can theoretically be as small as 1 transaction but are more often several thousand, depending on how much data each transaction stores.
This is the easy part. Second, in order to add a block of transactions to the blockchain, miners must solve a complex computational math problem, also called a "proof of work. In other words, it's a gamble.
The difficulty level of the most recent block at the time of writing is more than 13 trillion. That is, the chance of a computer producing a hash below the target is 1 in 13 trillion. To put that in perspective, you are about 44, times more likely to win the Powerball jackpot with a single lottery ticket than you are to pick the correct hash on a single try.
Fortunately, mining computer systems spit out many, many more hash possibilities than that. Nonetheless, mining for bitcoin requires massive amounts of energy and sophisticated computing rigs, but more about that later as well. The difficulty level is adjusted every blocks, or roughly every 2 weeks, with the goal of keeping rates of mining constant.
That is, the more miners there are competing for a solution, the more difficult the problem will become. The opposite is also true. If computational power is taken off of the network, the difficulty adjusts downward to make mining easier.
My friends don't have to guess the exact number, they just have to be the first person to guess any number that is less than or equal to the number I am thinking of. And there is no limit to how many guesses they get. There is no 'extra credit' for Friend B, even though B's answer was closer to the target answer of Rather, I'm asking millions of would-be miners and I'm thinking of a digit hexadecimal number.
Now you see that it's going to be extremely hard to guess the right answer. If 1 in 13 trillion doesn't sound difficult enough as is, here's the catch to the catch. Not only do bitcoin miners have to come up with the right hash, but they also have to be the first to do it.
Because bitcoin mining is essentially guesswork, arriving at the right answer before another miner has almost everything to do with how fast your computer can produce hashes. Just a decade ago, bitcoin mining could be performed competitively on normal desktop computers. Over time, however, miners realized that graphics cards commonly used for video games were more effective at mining than desktops and graphics processing units GPU came to dominate the game.
In , bitcoin miners began to use computers designed specifically for mining cryptocurrency as efficiently as possible, called Application-Specific Integrated Circuits ASIC. These can run from several hundred dollars to tens of thousands. Today, bitcoin mining is so competitive that it can only be done profitably with the most up-to-date ASICs. Even with the newest unit at your disposal, one computer is rarely enough to compete with what miners call "mining pools.
A mining pool is a group of miners who combine their computing power and split the mined bitcoin between participants. A disproportionately large number of blocks are mined by pools rather than by individual miners. Between 1 in 13 trillion odds, scaling difficulty levels, and the massive network of users verifying transactions, one block of transactions is verified roughly every 10 minutes.
The bitcoin network can process about seven transactions per second, with transactions being logged in the blockchain every 10 minutes. For comparison, Visa can process somewhere around 24, transactions per second. As the network of bitcoin users continues to grow, however, the number of transactions made in 10 minutes will eventually exceed the number of transactions that can be processed in 10 minutes.
At that point, waiting times for transactions will begin and continue to get longer, unless a change is made to the bitcoin protocol. There have been two major solutions proposed to address the scaling problem. Developers have suggested either 1 decreasing the amount of data needed to verify each block or 2 increasing the number of transactions that each block can store.
With less data to verify per block, the Solution 1 would make transactions faster and cheaper for miners. Solution 2 would deal with scaling by allowing for more information to be processed every 10 minutes by increasing block size.
That is, they went with Solution 1. The program that miners voted to add to the bitcoin protocol is called a segregated witness , or SegWit. Less than a month later in August , a group of miners and developers initiated a hard fork , leaving the bitcoin network to create a new currency using the same codebase as bitcoin.
Although this group agreed with the need for a solution to scaling, they worried that adopting segregated witness technology would not fully address the scaling problem. Instead, they went with Solution 2. Your Money. Personal Finance. Your Practice. Popular Courses. Login Newsletters. Part Of.

What's the big deal with mining anyway?
Maybe it's a sign of the Bitcoin bubble. Criminals are trying to take control of PCs and turn them into Bitcoin miners. According to antivirus seller Kaspersky Lab , there's a new Trojan — spotted just yesterday and spreading via Skype — that takes control of infected machines and forces them to do known as Bitcoin mining, a way of earning digital currency. The Bitcoin digital currency system rewards miners in Bitcoins, natch for their number-crunching work, which is essential to keeping the anonymous Bitcoin currency system working. With the Trojan, hackers are forcing others' machines to earn them money, and it can really put a strain on these machines. Victims might notice that their CPU usage shoots sky high.

You've heard of Bitcoin and you're ready to get your hands on some digital wealth. However, this may be easier said than. When you "mine" Bitcoin, you actually verify Bitcoin transactions in the public, decentralized ledger of Bitcoin transactions called the blockchain.
Every time you find a new block to add to the chain, the system gives you some Bitcoin as a reward. Back in the early days of Bitcoin, it was easy to mine Bitcoin using your own computer. However, as the cryptocurrency has become more popular, it has become all but impossible for individuals to make a profit mining Bitcoin. That doesn't stop a lot of people from trying. If you want to mine Bitcoin, you can either sign up with a cloud-mining company or build your own mining rig to mine for.
Tip: If you have a software or mobile wallet, keep in mind that your wallet is only as secure as the device where it's located. Make sure you have set up robust security on your computer or smartphone, with encryption, a firewall, and up-to-date antivirus protection.
Tip: Even if you start making Bitcoin fairly early on in your contract, you still have to cover the price you paid for the contract before you're turning a profit. Most smaller contracts never turn a profit.
For larger contracts, it may take you several years. Tip: You can access your router and your ASIC miner from any computer or electronic device on the same network as your miner — even your smartphone. Make sure your network is protected by a firewall and a strong password. To mine Bitcoins, start by downloading a Bitcoin wallet on your computer or mobile device, which you'll need to store your mined Bitcoins in.
Once you have a digital wallet, look for a cloud mining service provider online and sign up for one of their packages to receive processing power to mine Bitcoin remotely. Then, join a mining pool through the provider, which will increase your chances of earning Bitcoins. To learn what equipment you'd need to mine Bitcoin yourself at home, scroll down!

Software wallets are kept on your computer, while mobile wallets are apps that you install on your smartphone. Software and mobile wallets are reasonably secure, can be downloaded for free, and are suitable for smaller amounts of Bitcoin. Some wallets are hybrid, meaning that you can access them through software on your computer and through an app on your mobile phone. Invest in a hardware wallet if you're serious about Bitcoin. Hardware wallets may set you back a couple of hundred dollars but are considered more secure.
Since they aren't connected to the internet, they aren't vulnerable to hackers. If you intend to keep your Bitcoin long-term, a hardware wallet is likely a worthwhile investment. You can buy them online or at brick-and-mortar stores that sell computer supplies and accessories. Enable all security features on your wallet. Once you've chosen a Bitcoin wallet, set it up for maximum security to protect your Bitcoin. Use two-factor authentication to secure your account.
When you log in, a code will be sent to you in a text message or email. You have to enter the code to access your account. This makes your account less vulnerable to hacking. If you have a password manager on your computer or smartphone, you can use that to create a secure, encrypted password.
Method 2. Decide which cloud-mining service provider to use. There are a number of different cloud-mining service providers available, some of which are better established than. Each service charges different fees and has different contract packages available.
However, the most popular services with the best reputations also are frequently sold out of contracts. Research services carefully. There have been numerous cloud-mining scams. Make sure the company is legitimate and has a good reputation.
You can search the name of the service and see what people are saying online about it. Websites such as CryptoCompare can also help you analyze company reputations. Be careful of a cloud-mining service that makes guarantees or claims that sound too good to be true. It is likely a scam. No cloud-mining service can guarantee you a particular rate of return, or guarantee what does bitcoin mining do to your pc you'll break even or start turning a profit in a short amount of time.
Pick a cloud mining contract package. With cloud-mining, you essentially lease mining power from a miner farm for a period of time. While your contract is active, you get all the Bitcoin that is mined using that amount of mining power, minus fees paid to the cloud-mining service for maintenance of the mining hardware.
While shorter contracts may carry a lower price tag, it's unlikely that you'll make any money in a shorter period of time. You usually need at least 2 years to break. This sounds like a lot, but it's unlikely that you'd do much more than break even in 2 years on such a small plan. Withdraw your earnings to your secure wallet.
When you purchase your contract, your mining power goes to work for you immediately. As you earn Bitcoin, it will show up on your account at the cloud-mining service. When you've accumulated enough, you can send it to your wallet. Others may allow you to withdraw your earnings any time you want, as long as you have a minimum. The minimum can range anywhere from 0. Method 3.
Use an online mining calculator to calculate mining profitability. Mining rigs can be relatively expensive and consume a lot of power. Playing with different setups on an online mining calculator can help you determine whether it's worth it to you to start mining. If you're just getting started, you may not have all the information available, such as mining pool fees or power cost.
However, the more information you provide, the more accurate the profitability estimate will be. Buy ASIC miners and a power supply for your mining rig. Essentially, it's a computer chip that needs a power supply to run it. ASIC miners vary in price depending on their hashing power and their efficiency. You can monitor the price of Bitcoin to calculate changes what does bitcoin mining do to your pc the time it will take to turn a profit.
Profit may also vary based on the price of electricity. Connect your miner and boot it up. Connect your power supply to your ASIC miner, then connect your miner to your router. Use an ethernet cable to connect your miner — a wireless connection is not stable. This will take you to your router's admin page. This will enable you to configure your miner.
Download Bitcoin mining software to a networked computer. After you've connected your hardware, you need to download software so you can mine Bitcoin. There are a number of different mining programs to choose. These are both command-line programs, so if you aren't particularly tech-savvy, they may present a challenge for you. EasyMiner has a graphical interface that is more intuitive and easier to use, especially if you're a beginner with limited computer skills.
EasyMiner works on Windows, Linux, and Android machines. Join a mining pool. Mining pools are groups of miners that pool their hashing power to mine Bitcoin more quickly.
