In regions where electricity is generated using fossil fuels, bitcoin mining is considered detrimental to the environment. As a result, many bitcoin miners have moved operations to places with renewable sources of energy to reduce Bitcoin's impact on climate change. Just as gold is mined from the earth using large implements and machines, bitcoin mining also uses big systems akin to data centers.

These systems solve mathematical puzzles generated by Bitcoin's algorithm to produce new coins. By solving computational math problems, bitcoin miners also make the cryptocurrency's network trustworthy by verifying its transaction information. They verify 1 megabyte MB worth of transactions—the size of a single block. These transactions can theoretically be as small as one transaction but are more often several thousand depending on how much data each transaction stores.

The idea behind verifying Bitcoin transaction information is to prevent double-spending. With printed currencies, counterfeiting is always an issue. 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.

Bitcoin transactions are aggregated into blocks that are added to a database called blockchain. Full nodes in Bitcoin's network maintain a record of the blockchain and verify transactions occurring on it. Bitcoin miners download the entire history of blockchain and assemble valid transactions into a block. If the block of assembled transactions is accepted and verified by other miners, then the miner receives a block reward. Bitcoin halved its mining reward—from The block reward is halved every , blocks or roughly every four years.

In , it was In , the reward amount declined to 25, and in , it became In Bitcoin's most recent halving event, the reward was changed to 6. Another incentive for bitcoin miners to participate in the process is transaction fees. In addition to rewards, miners also receive fees from any transactions contained in that block of transactions.

As Bitcoin reaches its planned limit of 21 million expected around , miners will be rewarded with fees for processing transactions that network users will pay. These fees ensure that miners still have the incentive to mine and keep the network going. The idea is that competition for these fees will cause them to remain low after halving events are finished.

At the heart of bitcoin mining is a math puzzle that miners are supposed to solve in order to earn bitcoin rewards. The puzzle is called proof of work PoW , a reference to the computational work expended by miners to mine bitcoin. Though it is often referred to as complex, the mining puzzle is actually fairly simple and can be described as guesswork. The miners in Bitcoin's network try to come up with a digit hexadecimal number, called a hash, that is less than or equal to a target hash in SHA, Bitcoin's PoW algorithm.

The systems that guess a number less than or equal to the hash are rewarded with bitcoin. Here's an example to explain the process. Say you ask friends to guess a number between 1 and that you have thought of and written down on a piece of paper. If you are thinking of the number 19 and a friend comes up with 21, they lose because 21 is greater than But if someone guesses 16 and another friend guesses 18, then the latter wins because 18 is closer to 19 than In very simple terms, the bitcoin mining math puzzle is the same situation described above except with digit hexadecimal numbers and thousands of computing systems.

One of the terms you will often come across in bitcoin mining literature is mining difficulty. Mining difficulty refers to the difficulty of solving the math puzzle and generating bitcoin. Mining difficulty influences the rate at which bitcoins are generated. Mining difficulty changes every 2, blocks or approximately every two weeks. The succeeding difficulty level depends on how efficient miners were in the preceding cycle.

It is also affected by the number of new miners that have joined Bitcoin's network because it increases the hash rate or the amount of computing power deployed to mine the cryptocurrency. In and , as the price of bitcoin rose, more miners joined its network, and the average time to discover a block of transactions fell to nine minutes from 10 minutes. But the opposite can also be true. That is, the more miners there are competing for a solution, the more difficult the problem will become.

If computational power is taken off the network, the difficulty adjusts downward to make mining easier. The difficulty level for mining in March was That is, the chances of a computer producing a hash below the target is 1 in To put that in perspective, you are about 91, 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. At the end of the day, bitcoin mining is a business venture. Profits generated from its output—bitcoin—depend on the investment made into its inputs.

There are three main costs of bitcoin mining:. The total costs for these three inputs should be less than the output—in this case, the bitcoin price—for miners to generate profits from their venture. Considering the skyrocketing price of bitcoin, the idea of minting your own cryptocurrency might sound like an attractive proposition. However, despite what Bitcoin proponents tell you, mining the cryptocurrency is not a hobby of any sort.

It is an expensive venture with a high probability of failure. As illustrated in the section on mining difficulty, there is no guarantee that you will earn bitcoin rewards even after spending considerable expenses and effort. Aggregating mining systems to run a small business that mines bitcoin might offer a way out.

However, even such businesses are at the mercy of the cryptocurrency's volatile prices. If the cryptocurrency's price crashes as it did in , then it becomes uneconomic to run bitcoin mining systems, and small miners will be forced to go out of business. The decline in the number of bitcoins awarded to miners every four years makes the activity even more unappealing. Given the considerable difficulty inherent in the economics of mining bitcoin, the activity is now dominated by large mining companies that have operations spanning multiple continents.

AntPool, the world's biggest bitcoin mining company, runs mining pools in many countries. Many bitcoin mining companies have also gone public, although their valuations are relatively modest. For most of Bitcoin's short history, its mining process has remained an energy-intensive process. In the decade after it was launched, bitcoin mining was concentrated in China, a country that relies on fossil fuels like coal to produce a majority of its electricity.

Not surprisingly, bitcoin mining's astronomical energy costs have drawn the attention of climate change activists who blame the activity for rising emissions. According to some estimates, the cryptocurrency's mining process consumes as much electricity as entire countries. But bitcoin proponents have released studies that claim that the cryptocurrency is powered largely by renewable energy sources.

One thing to remember about these studies is that they are based on conjectures and self-reported data from mining pools. For example, a Coinshares report from makes several assumptions regarding the power sources for miners included in their assessment of the bitcoin mining ecosystem. Two developments have contributed to the evolution and composition of bitcoin mining as it is today.

The first one is the manufacture of custom mining machines for bitcoin. 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. In the early days of Bitcoin, desktop computers with ordinary CPUs dominated bitcoin mining. But they began taking a long time to discover transactions on the cryptocurrency's network as the algorithm's difficulty level increased with time.

According to some estimates, it would have taken "several hundred thousand years on average" using CPUs to find a valid block at the early difficulty level. Over time, miners realized that graphics cards, also known as graphics processing units GPUs , were more effective and faster at mining. But they consumed a lot of power for individual hardware systems that weren't really required for mining the cryptocurrency.

Nowadays, miners use custom mining machines, called ASIC miners, that are equipped with specialized chips for faster and more efficient bitcoin mining. They cost anywhere from several hundred to tens of thousands of dollars. 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 mining pools—groups of miners who combine their computing power and split the mined bitcoin between them. Bitcoin forks have also influenced the makeup of the bitcoin miner network. Between 1 in 16 trillion odds, scaling difficulty levels, and the massive network of users verifying transactions, one block of transactions is verified roughly every 10 minutes.

But it's important to remember that 10 minutes is a goal, not a rule. The Bitcoin network can currently process just under four transactions per second, with transactions logged in the blockchain every 10 minutes. By comparison, Visa can process somewhere around 65, 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.

This issue at the heart of the Bitcoin protocol is known as scaling. Though bitcoin miners generally agree that something must be done to address scaling, there is less consensus about how to do it. There have been two major solutions proposed to address the scaling problem. But our numeric system only offers 10 ways of representing numbers zero through nine. If you are mining Bitcoin, you do not need to calculate the total value of that digit number the hash.

I repeat: You do not need to calculate the total value of a hash. Remember that analogy, in which the number 19 was written on a piece of paper and put in a sealed envelope? In Bitcoin mining terms, that metaphorical undisclosed number in the envelope is called the target hash. What miners are doing with those huge computers and dozens of cooling fans is guessing at the target hash. Miners make these guesses by randomly generating as many " nonces " as possible, as quickly as possible.

A nonce is short for "number only used once," and the nonce is the key to generating these bit hexadecimal numbers I keep mentioning. In Bitcoin mining, a nonce is 32 bits in size—much smaller than the hash, which is bits. The first miner whose nonce generates a hash that is less than or equal to the target hash is awarded credit for completing that block and is awarded the spoils of 6.

In theory, you could achieve the same goal by rolling a sided die 64 times to arrive at random numbers, but why on Earth would you want to do that? The screenshot below, taken from the site Blockchain. You are looking at a summary of everything that happened when block No.

The nonce that generated the "winning" hash was The target hash is shown on top. The term "Relayed by AntPool" refers to the fact that this particular block was completed by AntPool, one of the more successful mining pools more about mining pools below. As you see here, their contribution to the Bitcoin community is that they confirmed 1, transactions for this block. If you really want to see all 1, of those transactions for this block, go to this page and scroll down to the Transactions section.

Source : Blockchain. All target hashes begin with a string of leading zeroes. There is no minimum target, but there is a maximum target set by the Bitcoin Protocol. No target can be greater than this number:.

The winning hash for a bitcoin miner is one that has at least the minimum number of leading zeroes defined by the mining difficulty. Here are some examples of randomized hashes and the criteria for whether they will lead to success for the miner:. To find such a hash value, you have to get a fast mining rig, or, more realistically, join a mining pool—a group of coin miners who combine their computing power and split the mined Bitcoin.

Mining pools are comparable to Powerball clubs whose members buy lottery tickets en masse and agree to share any winnings. A disproportionately large number of blocks are mined by pools rather than by individual miners. In other words, it's literally just a numbers game. You cannot guess the pattern or make a prediction based on previous target hashes.

At today's difficulty levels, the odds of finding the winning value for a single hash is one in the tens of trillions. Not great odds if you're working on your own, even with a tremendously powerful mining rig. Not only do miners have to factor in the costs associated with expensive equipment necessary to stand a chance of solving a hash problem, but they must also consider the significant amount of electrical power mining rigs utilize in generating vast quantities of nonces in search of the solution.

All told, Bitcoin mining is largely unprofitable for most individual miners as of this writing. The site CryptoCompare offers a helpful calculator that allows you to plug in numbers such as your hash speed and electricity costs to estimate the costs and benefits.

Participants with a small percentage of the mining power stand a very small chance of discovering the next block on their own. For instance, a mining card that one could purchase for a couple of thousand dollars would represent less than 0. With such a small chance at finding the next block, it could be a long time before that miner finds a block, and the difficulty going up makes things even worse.

The miner may never recoup their investment. The answer to this problem is mining pools. Mining pools are operated by third parties and coordinate groups of miners. By working together in a pool and sharing the payouts among all participants, miners can get a steady flow of bitcoin starting the day they activate their miners.

Statistics on some of the mining pools can be seen on Blockchain. As mentioned above, the easiest way to acquire Bitcoin is to simply buy it on one of the many Bitcoin exchanges. Alternately, you can always leverage the "pickaxe strategy.

To put it in modern terms, invest in the companies that manufacture those pickaxes. In a cryptocurrency context, the pickaxe equivalent would be a company that manufactures equipment used for Bitcoin mining. The risks of mining are often financial and regulatory. As aforementioned, Bitcoin mining, and mining in general, is a financial risk because one could go through all the effort of purchasing hundreds or thousands of dollars worth of mining equipment only to have no return on their investment.

That said, this risk can be mitigated by joining mining pools. If you are considering mining and live in an area where it is prohibited, you should reconsider. It may also be a good idea to research your country's regulation and overall sentiment toward cryptocurrency before investing in mining equipment. One additional potential risk from the growth of Bitcoin mining and other PoW systems as well is the increasing energy usage required by the computer systems running the mining algorithms. Though microchip efficiency has increased dramatically for ASIC chips, the growth of the network itself is outpacing technological progress.

As a result, there are concerns about Bitcoin mining's environmental impact and carbon footprint. There are, however, efforts to mitigate this negative externality by seeking cleaner and green energy sources for mining operations such as geothermal or solar sources , as well as utilizing carbon offset credits.

Switching to less energy-intensive consensus mechanisms like proof-of-stake PoS , which Ethereum has transitioned to, is another strategy; however, PoS comes with its own set of drawbacks and inefficiencies, such as incentivizing hoarding instead of using coins and a risk of centralization of consensus control. Mining is a metaphor for introducing new bitcoins into the system because it requires computational work just as mining for gold or silver requires physical effort.

Of course, the tokens that miners find are virtual and exist only within the digital ledger of the Bitcoin blockchain. Because they are entirely digital records, there is a risk of copying, counterfeiting, or double-spending the same coin more than once. Mining solves these problems by making it extremely expensive and resource-intensive to try to do one of these things or otherwise "hack" the network. Indeed, it is far more cost-effective to join the network as a miner than to try to undermine it.

In addition to introducing new BTC into circulation, mining serves the crucial role of confirming and validating new transactions on the Bitcoin blockchain. This is important because there is no central authority such as a bank, court, government, or anything else determining which transactions are valid and which are not. Instead, the mining process achieves a decentralized consensus through proof of work PoW.

In the early days of Bitcoin, anybody could simply run a mining program from their PC or laptop. But as the network got larger and more people became interested in mining, the mining algorithm became more difficult. This is because the code for Bitcoin targets finding a new block once every 10 minutes, on average.

If more miners are involved, the chances that somebody will solve the right hash quicker increases, and so the difficulty increases to restore that minute goal. Now imagine if thousands, or even millions more times that mining power joins the network.

That's a lot of new machines consuming energy. The legality of Bitcoin mining depends entirely on your geographic location. The concept of Bitcoin can threaten the dominance of fiat currencies and government control over the financial markets. For this reason, Bitcoin is completely illegal in certain places. Bitcoin ownership and mining are legal in more countries than not. Some examples of places where it was illegal according to a report were Algeria, Egypt, Morocco, Bolivia, Ecuador, Nepal, and Pakistan.

Overall, Bitcoin use and mining remain legal across much of the globe. Because blockchain mining is very resource-intensive, it can put a large strain on your GPU or other mining hardware. In fact, it is not unheard of for GPUs to blow out, or for mining rigs to burst into flames.

However, keeping your rigs running at a moderate pace and with sufficient power supplied, it is generally safe. Bitcoin mining today requires vast amounts of computing power and electricity to be competitive. Running a miner on a mobile device, even if it is part of a mining pool, will likely result in no earnings. Bitcoin "mining" serves a crucial function to validate and confirm new transactions to the blockchain and to prevent double-spending by bad actors.

It is also the way that new bitcoins are introduced into the system. Based on a complex puzzle, the task involves producing proof of work PoW , which is inherently energy-intensive. This energy, however, is embodied in the value of bitcoins and the Bitcoin system and keeps this decentralized system stable, secure, and trustworthy.

Traditional money can be printed in the form of banknotes or digital on bank accounts. It is stored virtually on computer servers. You can use an ATM to withdraw cash from your credit card and put it under the mattress. In this case, your digital, virtual money becomes real. You can touch it, look at it, or hang it on the wall. Of course, you can exchange Bitcoins for dollars and bring them home.

At this point though, they are dollars, not Bitcoins. How crucial is it? We think not at all. Even most of our grandparents have been receiving pensions on bank accounts. Plus, virtual, digital dollars are stored on bank accounts. How many? Nobody knows. The same goes for the euro, pound, and any other traditional currency. We can neither control nor predict the issuing of dollars. The government of any country can print banknotes at any time. Things are much more straightforward with Bitcoins.

As of now, there are almost 19 million Bitcoins BTC in the world. About new BTC are created every day, but the daily amount of new Bitcoins is decreasing with time. In total, there will be 21 million Bitcoins in the world. The precise amount is 20,, No more, no less. If the Federal Reserve decides to print million dollars, they just print them.

They are not going to ask you or us. Their amount is limited to 21 million coins. Traditional currencies are controlled by central banks of respective countries. Nobody controls Bitcoin. Bitcoin is an anarchic system. The source code prescribes everything that should be happening in the system of this currency. In the next chapter, we are going to see how it works. Transactions in traditional currencies like dollars are controlled by banks. How does it work? Can anyone but you and bank workers find out that you sent money to your grandmother?

Did it go through? Will it go through in 20 minutes or in 24 hours? Please wait. All Bitcoin wallets are interconnected. They communicate with each other all the time sharing information about all cryptocurrency transactions. You have 1 BTC, and you want to send 0. Up until this point, everything is the same with the only difference being that the Bitcoin account number contains more letters and has more symbols overall.

Your wallet transmitted the information about the transaction to all other wallets. However, simply transmitting the information is not enough. Somebody should execute validate this transaction. In the case of traditional money, banks do it. In the case of Bitcoin, a computer or a group of computers do it. The computer gets a reward for the transaction. It must solve a complicated math problem that changes every 10 minutes in a highly competitive environment. This process is called mining, and we are going to discuss it in the next chapter.

All the data in the Bitcoin system is open to any person. All information about transactions is public. However, this information is anonymous. For example, 0. Any person in the world can verify it. You will see for yourself that your money is transferred to your grandmother and is now in her wallet.

You can show it to other family members. They are interconnected and serve as a foundation for cryptocurrencies. We already mentioned that information about all transactions in the Bitcoin system is available to all people. This information is stored on the blockchain. Blockchain literally means the chain of blocks. There is nothing complicated about this term.

Blockchain is like a ledger where pages are numbered sequentially, each page contains the data of creation and a list of transactions performed at this moment of time. One page is called a block. By the way, this data is real. You can find it in the Bitcoin network by following the link. Similar ledgers have existed since the times of Ancient Rome. However, one thing distinguishes blockchain.

We have a notebook with an endless number of pages and start filling out the first page. All wallets in the Bitcoin network communicate with each other. We receive new data. And so on. We record all the data on the first page of the notebook. We keep receiving more information about transactions.

We keep recording. Until we turn the page, all these transactions are void. How to turn the page? Only cryptocurrency miners can do it. If we are not miners, there is no way for us to do it. We ask a miner for help, and he turns the page. He also puts time and his name on it. Miners get rewards for their work, which is also recorded on the page before turning and sealing it.

Then we fill the second page with new transactions. To turn it, we ask a miner again. There is no way around it. This process is endless. Blockchain is open to all people at all times. You can open any page of the so-called ledger and see who made a transfer, to whom, when, and how much. You can also see the balance of any wallet in Bitcoin.

You will only see addresses, but all the information is public. If you want to see it for yourself, you can go to blockchain. Easy, right? We are sure that now you too want to become an important person that everyone needs to close a new block on the blockchain i. Plus, they say you get paid well for it. Bitcoin mining is the process of solving a math problem using computing equipment.

The problem is the same for all the computers in the world. By doing so, he validates all the transactions recorded since the closure of the previous block. Once the problem is solved, another problem appears. The whole world starts working on it. How often do problems change? Bitcoin source code is written in such a way that it takes about 10 minutes to solve a problem. It is enabled through a simple algorithm.

The more miners are working on the problem, the more difficult it is.

It is enabled through a simple algorithm. The more miners are working on the problem, the more difficult it is. And vice versa: less miners would be solving an easier problem. Unlike traditional currencies, cryptocurrencies are anonymous but completely transparent. Ironic but true. Senders and recipients are identified with wallet addresses instead of names, like the gibberish we already mentioned above: 1CKXsyrhF9zfzizZb1x9zwkHczjxNRc6by.

On the one hand, it guarantees full anonymity. On the other hand, if you match a real person with his Bitcoin address, you can see all his transactions: how much he transferred and to which addresses. One important thing that distinguishes Bitcoin from the dollar or euro is that nobody regulates or safeguards Bitcoin in any way.

Here is a simple example. You would contact your bank and file an application. It is almost certain that you will get your money back. If you transfer 0. There is no mechanism that would let you get your money back. There is no Bitcoin police. In this case, cryptocurrencies are like cash. Storing cryptocurrencies is as unsafe as storing cash. The only difference is that banknotes are pieces of paper, and you can only stash a limited number of those.

On the contrary, an unlimited number of Bitcoins can be stored on a flash drive, or even in a tiny file on your computer. Keep in mind the important difference between transactions in cryptocurrencies and traditional currencies. When you transfer Bitcoins and the transaction gets sealed on the blockchain, your money has already left your account and reached the recipient.

When you transfer dollars from one account to another, they may be already gone from the sending account but only reach the recipient in a day or two, or they may get lost due to the negligence of the bank. A person can be engaged in both activities, but there is a difference. Mining brings immediate profits, whereas investment brings profits in the long run.

Regardless of how you are planning to use Bitcoins, you need a wallet. Choosing the right wallet is important. You are responsible for the safety of your cryptocurrency. Remember that if your cryptocurrency gets stolen or lost, nobody will be able to restore it. Whichever wallet you choose, there is a risk of losing your Bitcoins. Depending on the wallet and type of storage, the risk may be higher or lower. If you are not planning to store large sums of money or you are only starting out, we recommend one of the multicurrency cryptowallets.

They are available on desktop and mobile. For example, Coinomi or Trust. Hardware wallets offer a higher level of security. They are special flash drives that you connect to your computer. In the case of such wallets, avoid buying used wallets or wallets from unverified sources.

Hardware wallets must be new and bought directly from the manufacturing company. If you plan to store large sums, you need more secure storage. For example, you may want to buy a separate computer and a few flash drives to store cryptocurrencies. There are plenty of scammers and hackers. There are special cryptocurrency exchanges and platforms that let you buy, sell, and exchange Bitcoins for other cryptocurrencies.

Most of them require registration and ID verification. You can still find some exchanges that operate anonymously. In any case, exchanging one cryptocurrency for another is much easier than exchanging cryptocurrency for dollars. All you need to do is to go to one of the exchanges with multiple exchange options. The most popular exchanges in the world are Coinbase , Gemini , Kraken , and Binance. The regulations differ depending on the country. Mining is not as hard as it may seem at first glance.

Mining pools are servers that connect miners. Miners work together and get a reward. Mining pools distribute the reward fairly and pay out the earned cryptocurrency to each miner. If you have a desktop gaming computer with a graphics card, you can start mining even today. Go to 2CryptoCalc and check which cryptocurrency is the best for mining on your graphics card. Then follow the instructions of a mining pool. You will need to install a special mining software and a wallet for the cryptocurrency you are going to mine.

You can only mine it on specialized ASIC devices. As of now, one of the most advanced devices is the Antminer S19 Pro by Bitmain. It consumes 3. You just need to open your ASIC settings to add the mining pool address and your Bitcoin wallet address, connect your device to the Internet, and plug it in. In this small chapter, we will show you the two most common ways people become part of the cryptocurrency world.
