Firstly, Bitcoin is a digital currency created in 2009 for people to send and receive money directly, without any central authority like banks or governments. Instead, it relies on a large network of computer users known as Bitcoin Mining to manage transactions.
So, why are we here? Well, we are here to answer a common question: How Does Bitcoin Mining Actually Work?
What Exactly Is Bitcoin Mining?
When people talk about getting into cryptocurrency mining, it might seem like something only tech experts can handle, making Bitcoin mining seem like a complex task. However, it is not limited to tech wizards. While it is not easy, cryptocurrency mining can be both challenging and costly, but the rewards can be significant. Bitcoin Miners receive a share of crypto tokens and transaction fees from Bitcoin users who send and receive crypto through blockchain.
Honestly, crypto miners are making millions in this field. In just over a decade, cryptocurrency has become a global currency, and there are already countless crypto miners earning substantial incomes from mining. However, before you get too excited about the rewards, keep in mind that crypto mining requires effort, time, and some initial investment to buy the necessary equipment and tools.
What is the Reason Behind Bitcoin Mining Rewards?
Bitcoin miners act as the security guards of the Bitcoin network. They verify and validate Bitcoin transactions, ensuring they are legitimate and secure. Think of them like digital police, safeguarding the coin holders and the blockchain to prevent fraud and breaches. In return for their efforts, they receive Bitcoin tokens (BTC) as a reward. This reward is an incentive to encourage more miners to maintain the security and integrity of the currency.
In simple terms, miners take on the role of traditional banks and governments, but in a decentralized way. They ensure that Bitcoin transactions proceed as they should, without third-party control over the currency.
How Does the Bitcoin Mining Process Function?
In technical terms, Bitcoin mining involves a combination of hardware and software systems. Miners, represented by machines on the Bitcoin network, play a good role in securing the network. They use various types of hardware to mine Bitcoin blocks. This mining process entails adding transaction records to Bitcoin’s public ledger, known as the blockchain.
To be considered valid, a transaction must be signed by the sender. Miners continuously monitor Bitcoin transactions and work to verify them. On average, every 10 minutes, a new block of transactions is added to the blockchain in the network through this verification process.
Varieties of Bitcoin Mining Equipment
There are popularly used hardware options for Bitcoin mining, but each faces challenges such as low profits, excess heat, and high electricity costs. Recently, cloud mining has emerged as a solution to these issues, as it does not deal with excessive heat or high electricity costs, although it comes with its own limitations. Miners, which are hardware devices, use their processing power to solve transaction problems and broadcast them on the network.
The types of Bitcoin mining hardware include:
- CPU mining
- GPU mining (Graphics Processing Unit)
- FPGA mining
- ASIC mining (Application-specific Integrated Circuit)
A block is considered valid when it has proof of work, and the miner who successfully mines a block receives a reward. Miners earn new Bitcoins as a reward and collect transaction fees from all the transactions included in the block. This serves as motivation for miners to continuously compete to find valid blocks to mine.
It is important to note that while mining is one way to acquire cryptocurrency tokens or addresses, there are other methods as well. You can obtain crypto through fiat currency, exchange it for other cryptocurrencies, receive cryptocurrency as payment for online work, and explore various other avenues.
What Are the Responsibilities of Bitcoin Miners?
In the world of Bitcoin, there is a concern called double-spending. This occurs when someone tries to use the same Bitcoin token for multiple transactions. For example, a sender may send a specific amount of Bitcoin to one person and then make a copy of that same Bitcoin to send to another person, even though the token has already been used or sold to the first customer. What Bitcoin MINERS do is verify these previously sent Bitcoin tokens to ensure they are not used again (preventing Double-Spending).
Bitcoin miners are important because they help prevent fraudulent activities and false transactions. Without them, cryptocurrency would be highly vulnerable to misuse. Miners hold spenders and coin owners accountable, promoting honesty and transparency throughout the Bitcoin network and blockchain. In simpler terms, you can think of Bitcoin miners as the internal auditors of the Bitcoin system.
Traditional Explanation of Bitcoin Mining
Imagine you have two $10 bills, one real and one counterfeit, like two identical-looking dollar bills. Now, let’s say you go to a coffee shop to buy two cups of coffee, each priced at $10. The cashier carefully examines the serial numbers on the dollar bills and realizes that one of them is fake.
In the world of Bitcoin, miners play a similar role. They use a distributed consensus system to assess the legitimacy of transactions. Their job is to ensure that a Bitcoin sender or owner is not trying to use the same Bitcoin for two different transactions, which would make the second transaction invalid and fraudulent, just like the counterfeit $10 bill in the example.
Earning Rewards: Miners and the Block-Chain
The blockchain stands out as one of the most remarkable inventions of the 21st century. In technical terms, it is a time-stamped series of unchangeable data records managed by a network of computers, not controlled by any single entity. These people data records, referred to as blocks, are secured and linked together through cryptographic methods.
In Bitcoin, a block of transactions equals 1 MB in size. When a miner successfully verifies a block of Bitcoin transactions, they receive a fixed amount of Bitcoin as a reward. This reward system was established by Bitcoin’s founder, Satoshi Nakamoto.
However, in recent times, some miners have advocated for increasing the block size, which would speed up the verification process, allowing miners to verify more blocks and earn more rewards with less effort.
It is important to note that not every verified transaction guarantees a reward. There are specific rules, procedures, and processes that determine eligibility for miner rewards. To be eligible, you need to meet two key conditions:
- Mine a block containing 1 MB worth of coin transactions.
- Be the first miner to provide the correct result for block verification, known as Proof of Work.
The Role of Bitcoin Miners
Many people initially shy away from the concept of Bitcoin mining because they have heard it involves complex mathematical computations and algorithms. Some describe mining as akin to solving puzzles by finding the right numerical combination that fits a specific target.
In a way, that is partly true. To put it simply before delving into the six key tasks of a miner, the competition mainly revolves around being the first to discover a hexadecimal 64-digit number that is equal to or less than a specified target hash. However, it is important to understand that this task is not a walk in the park, given the high hash rates, ranging from megahashes (MH/s) per second to gigahashes (GH/s) per second, all the way to terahashes (TH/s) per second, required to arrive at the correct answer. The real challenge lies in being the first among millions of other miners to verify the same added block and find this target number.
The Role of a Bitcoin Miner: 6 Essential Tasks
A Bitcoin miner’s tasks involve:
- Listening for network transactions and verifying their correctness to prevent double spending.
- Maintaining a full copy of the blockchain and validating new blocks, including transaction verification and nonce validity checks.
- Grouping verified transactions into a new block, extending the latest one.
- Searching for a valid nonce, a good step in the mining process.
- Once a block is accepted, it may become part of the consensus chain if other miners accept it and mine on top of it.
- Miners who contributed to a block is validation receive rewards, currently set at 12.5 Bitcoins, along with any transaction fees.

Bitcoin Mining and How It Powers Bitcoin Circulation
As mentioned before, being a Bitcoin miner comes with a reward of approximately 12.5 BTC for every 1MB of transactions mined. However, miners do more than just verify Bitcoin transactions; they also play a crucial role in circulating Bitcoin by introducing new bitcoins into the market. In essence, miners contribute to the growth of the Bitcoin ecosystem.
The Role of Bitcoin Mining in Expanding Bitcoin Circulation
As of the first quarter of 2020, statistics indicate that there are approximately 18.3 million Bitcoins (BTC) in circulation, accounting for roughly 85% of the total estimated 21 million Bitcoins. This significant quantity of Bitcoin has entered circulation thanks to the efforts of miners, with the exception of the very first Bitcoin released through the Genesis Block by its founder, Satoshi Nakamoto.
It is important to note that even if miners were to cease their mining activities, there would still be existing Bitcoin in circulation within the blockchain network and market. However, without the continuous creation of new Bitcoins, there would likely be a shortage of supply, leading to increased demand and subsequently driving up the price of one BTC.
What Occurs After the Mining of 21 Million Bitcoins?
Let’s face the reality: even without Coin miners, the Bitcoin cryptocurrency system would continue to function, facilitating transactions. However, the absence of miners would mean no new Bitcoins introduced into the network. This raises concerns among some miners and potential entrants into the mining field.
To address the question of what happens when the total 21 million Bitcoins are mined, it is essential to recognize that this event is not imminent. Bitcoins are mined over time, and the last Bitcoin is projected to be mined by the year 2140. Whether there will be a new proposed release amount after the initial 21 million are mined remains uncertain.
You have to note that the diminishing number of Bitcoins available for mining doesn’t necessarily mean reduced rewards for miners. While the fixed reward of 12.5 BTC per block may decrease, miners also earn from transaction fees associated with Bitcoin transactions processed on the blockchain network.
Furthermore, being a Bitcoin miner gives you and idea as well as influence over potential future decisions, actions, changes, and regulations within the Bitcoin network. As previously mentioned, no single entity controls Bitcoin; it is a decentralized system managed collectively by its users. However, it is important to acknowledge that miners will likely wield significant influence over the fate of Bitcoin as it evolves.
One aspect of this influence involves decisions regarding forks in the Bitcoin network. But before delving further, let’s provide a brief explanation of the Bitcoin miner’s reward system and how it is governed.
What Is the Earnings of a Bitcoin Miner?
The Reward for Mining
The Bitcoin mining reward diminishes as the total number of Bitcoins in circulation approaches the limit of 21 million. This reduction occurs approximately every 210,000 blocks, which equates to about four years. At present, the mining reward stands at 12.5 Bitcoins.
When Bitcoin was first introduced in 2009, the reward for mining was 50 Bitcoins. In 2012, it was halved to 25 BTC, and then in 2016, it was reduced again to 12.5 BTC, where it remains as of 2020. The next scheduled reduction will bring the reward down to 6.25 BTC in 2024.
In addition to the mining reward, miners also receive transaction fees for successfully adding transactions to the blockchain. Typically, these transaction fees amount to approximately 1% of the block reward.
Important Note: Bitcoin Halving reduces miner rewards every 4 years.

Bitcoin Price History
Let’s briefly explore key milestones in the price of Bitcoin on the global market. Bitcoin was launched in January 2009, but during its early months, there were no exchanges or markets accepting Bitcoin. Users primarily engaged in cryptocurrency out of curiosity, and Bitcoin held low or negligible value.
To illustrate the initial skepticism, in March 2010, a user named “SmokeTooMuch” attempted to auction 10,000 BTC for a total of $50, but no buyers emerged. However, the tide turned with the emergence of the first Bitcoin exchange, Bitcoinmarket.com, leading to a significant price increase from 0.003 BTC to the unquantifiable value of today’s 1 BTC at $9,237.66.
Bitcoin Miner Earnings per Mined Block
Let’s rewind to November 2019. During that time, the price of 1 Bitcoin (1 BTC) had surged to $9,300. This means that a miner who successfully mined a full block of transactions and received a reward of 12.5 BTC would have earned approximately $115,470.75 when converted to dollars. To gauge its value at the current Bitcoin price, let’s calculate that.
Tools for Bitcoin Mining
Back in 2019 when Bitcoin mining was introduced, miners could effectively mine Bitcoin using home computers. The mining process was relatively straightforward and less demanding compared to today. The goal was to mine one block approximately every 10 minutes to maintain balance in the blockchain network and Bitcoin transactions. Achieving this required more miners and specialized equipment to compute the 65 hexadecimal Bitcoin tokens more efficiently.
Mining a block demands significant computational power and incurs electricity consumption costs. This led hardware companies to develop specialized mining equipment. Over time, Bitcoin mining hardware has evolved significantly. When Bitcoin was launched in 2009, the mining difficulty level was set at 1. Today, the difficulty level has skyrocketed to 13 trillion, reflecting the immense growth in Bitcoin mining. The difficulty level adjusts every 2016 blocks, which takes approximately two weeks to mine.
With millions of miners participating in the network, competition for mining rewards intensified. The first miner to provide the correct many solution for a mined block receives the reward. This drove the demand for high-performance hardware capable of delivering speed and precision in the mining process.
Necessary Mining Equipment – Mining Hardware
Mining Bitcoin necessitates specific hardware, and miners have utilized various types of hardware as technology has advanced. Initially, Bitcoin mining relied on CPUs, but over the years, miners transitioned to GPUs, FPGAs, and ASICs for more efficient mining.
Mining with Central Processing Units (CPU)
During the initial phase of Bitcoin mining, Central Processing Units (CPUs) served as the primary mining hardware. This era is often referred to as the first generation of Bitcoin mining. CPU mining involved running code that searched for nonces linearly, then executed SHA-256 calculations in software to verify the validity of a block. High-end desktop PCs could achieve around 20 million hashes per second (MH/s) with this method. However, at this speed, it would take several years on average to discover a valid block, rendering CPU mining obsolete.
GPU Mining: The Transition to Graphics Processing Units (GPUs)
GPU mining represents the second generation of Bitcoin mining, initiated due to the limited computational power of CPU mining. While GPU mining improved upon CPU mining, it still struggled to keep pace with the rising difficulty level over time. This method had its drawbacks, including issues with overheating and extensive hardware usage during mining operations.
Transition to FPGAs
FPGA mining, the third generation of Bitcoin mining, gained popularity when miners transitioned from GPU mining. Initially, FPGA mining offered superior computational power compared to GPUs. However, as more miners joined and network difficulty increased, FPGA mining could not meet expectations, leading to the rise of ASIC mining.
ASIC Mining: The Next Evolution in Bitcoin Mining
Bitcoin mining has evolved over time. Today, Bitcoin mining is mainly done using specialized machines called ASICs. ASICs are designed specifically for mining Bitcoins. Big companies make these machines and sell them to Bitcoin miners. Some examples of these machines include Antminer S9, Terminator T3, Dragonmint T1, and others. You can find them for sale online, often on websites like Amazon, at affordable prices.
Some people might feel discouraged at this stage due to the significant effort, time, and initial investment required to become a cryptocurrency miner. In fact, around 50% of those who try cryptocurrency mining, whether it’s for Bitcoin, Ethereum, or other cryptocurrencies, struggle to recover their investment and may never successfully mine a block.
However, there is an alternative solution known as pool mining, which I will briefly explain. The method I described earlier, where miners acquire their own mining tools, equipment, or hardware and mine on their own, is called solo mining. Now, let’s delve into both methods in more detail.
Solo Mining Cryptocurrency
Solo mining means mining Bitcoin individually using your hardware. It is a solo effort, and you do not team up with others in a mining pool. Solo miners compete on their own to solve blocks and earn rewards. However, solo mining demands substantial hardware resources and can be slow, sometimes taking years to solve a block. Pool mining, introduced in 2011, changed the game by allowing miners to work together for more consistent rewards. Before that, everyone was a solo miner.
Pool Mining Cryptocurrency
Pool mining is a collaborative method where miners combine their resources for more consistent payouts. Miners in a pool share a unique ID and work together to speed up mining. Pools lower the difficulty level for each member, making it easier to solve the mining problems. Miners submit their work (shares) to the pool for verification, and when a share meets the target value, the pool claims a block and rewards all miners. The “Pay-per-share” payout is common in pool mining, and you can find statistics on sites like www.blockchaininfo.com.
Bitcoin Transactions Simplified
A Bitcoin transaction is like a digital contract that transfers Bitcoin ownership. Your wallet creates this transaction and broadcasts it to the network. Nodes on the network validate and include it in a block, usually within 10-20 mins. Then, the receiver can see the transaction in their wallet.
Important Considerations for Bitcoin Transactions
- When a sender wants to send Bitcoin, they send it to an address linked to the recipient’s Bitcoin wallet.
- The Bitcoin received is associated with and secured by the recipient’s receiving address, which is part of their Bitcoin wallet.
- Whenever Bitcoin is spent, it is always taken from the funds previously received and currently stored in the Bitcoin wallet.
- Addresses are designed to receive Bitcoin, not to send it; the sending of Bitcoin is done through a wallet.
Bitcoin Address Token: The 64-Digit Hexadecimal Number in Your Bitcoin Wallet
Understanding Bitcoin Addresses: The 64-Digit Hexadecimal Number. In Bitcoin trading and mining, addresses are represented as a 64-digit hexadecimal number, combining letters and numbers to form a unique identifier. This numbering system is hexadecimal, with 16 possible digits (0-9 and a-f) for each position. Miners aim to guess the target hash, a specific combination within this 64-digit code, to earn the 12.5 BTC reward.
Deciphering the Mining Target Hash
A target hash is a shared 256-bit number among miners, affecting the Bitcoin network’s difficulty. Lower targets make block discovery harder. Miners compare each hash they generate to this target. If it is equal to or less than the target, they earn a reward. Otherwise, they increment the nonce and try again. Faster miners have an advantage, but the process is random, giving slower miners a chance. The target value recalculates every 2016 blocks, roughly every 14 days.
Miners Engaging in Target Hash Guesswork
The Bitcoin protocol sets a maximum target, it’s important for all miners to know that all target hashes start with 8 zeros and must contain up to 63 zeros. (00000000ffff0000000000000000000000000000000000000000000000000000)
How Miners Can Anticipate the Target Hash Faster than Competitors
The Quickest Route to Target Hash: Team Up for Mining Success. Joining a mining pool and collaborating with others can boost your odds of hitting the target hash swiftly and efficiently, increasing your chances of successful mining rewards.
Is Bitcoin Mining a Profitable Venture?
New miners may face high costs for hardware, electricity, and the effort needed to mine Bitcoin. Starting solo mining may not be profitable, so joining a mining pool is a better option.
Another choice is to invest in companies making mining hardware for potential profit without much effort. You can also consider buying and selling various cryptocurrencies like Bitcoin, Ethereum, and others.
As for Bitcoin prices, we have witnessed its incredible journey from obscurity to being recognized as a valuable digital asset. The volatile nature of Bitcoin prices has intrigued investors and traders alike, with its value fluctuating dramatically over the years.
