How many bitcoins are there and how many are left to mine? [UPDATED]

How many bitcoins are there and how many are left to mine


Bitcoin has gone a long way since its debut in 2009. However, what has stayed consistent is its hard limit, which was imposed by Satoshi Nakamoto, the alleged creator whose true identity is unknown. 

In the source code, Nakamoto set the upper limit of 21 million bitcoins, implying that no more can be mined or circulated. Although Nakamoto did not explain establishing the limit of 21 million, many people consider it a significant benefit for the world’s oldest cryptocurrency. According to them, the cryptocurrency’s limited quantity maintains it scarce and keeps its price stable for years.

With the set limit comes the most sought-after questions “How many bitcoins have been mined and how many are left?” “How is the limited supply of bitcoins achieved?” “What happens after all the bitcoins are mined?” Read ahead to find the answers.

What is Bitcoin?

Bitcoin is a digital currency that allows for peer-to-peer transactions without the need for a central intermediary. It was created in 2009 by an anonymous person or group of people using the pseudonym Satoshi Nakamoto. Bitcoin is based on a decentralized system, which means it is not controlled by any government or financial institution.

The main feature that distinguishes Bitcoin from traditional currencies is that it operates on a peer-to-peer network, which means that there is no central authority regulating it. Transactions are processed and verified by a network of computers around the world, called nodes, and recorded on a digital ledger called the Blockchain.

The Blockchain is a decentralized and immutable ledger that allows for transparency, security, and verifiability of transactions. It contains a record of all the transactions ever made on the Bitcoin network and cannot be tampered with, making it a secure and transparent way to exchange value online.

Defining Bitcoin as a decentralized digital currency

Bitcoin’s decentralization is a fundamental aspect. It means there’s no central authority, like a bank or government, overseeing transactions. Instead, a vast network of computers, known as miners, validates and records transactions on a public ledger called the Blockchain.

The technology underpinning Bitcoin: Blockchain

The Blockchain is the backbone of Bitcoin. It’s a distributed ledger that records every transaction ever made with Bitcoin. This ledger is stored on thousands of computers worldwide, making it highly secure and resistant to tampering. Each “block” in the Blockchain contains a batch of transactions, and new blocks are added in a chronological order, forming a chain.

Brief History of Bitcoin

Bitcoin creation:

  • Bitcoin was created in 2009.
  • It was made by someone using the name Satoshi Nakamoto.
  • The goal was to make a digital currency without a central authority.

Early users:

  • Initially, Bitcoin was used mainly by computer enthusiasts and libertarians.
  • They liked the idea of a decentralized currency.

Growing usage:

  • Over time, more people started using Bitcoin for payments and investments.
  • First real-world purchase:
  • In 2010, Laszlo Hanyecz bought two pizzas for 10,000 bitcoins.
  • Bitcoin had low value then, so it was seen as a novelty.

Rising value:

  • Bitcoin’s value increased significantly.
  • In 2013, it reached over $1,000 per Bitcoin.

Price crash:

  • In late 2013, Bitcoin’s price crashed.
  • It lost more than 80% of its value.
  • Reasons included the Mt. Gox exchange collapse and regulatory concerns.

Continued growth:

  • Despite the crash, Bitcoin gained more popularity.
  • Many merchants now accept it as payment.

Current status:

  • Today, thousands of businesses accept Bitcoin.
  • The total value of all cryptocurrencies is over $2 trillion.
  • Bitcoin experienced a significant surge in October 2023, rising from $27,967.51 to approximately $35,000. This surge was driven by various factors, including the anticipation of Bitcoin Exchange-Traded Funds (ETFs). Bitcoin’s rise was fueled by the anticipation of Exchange-Traded Funds (ETFs), positive regulatory developments, and increased accessibility through ETFs. Speculation around ETFs, institutional interest, and positive market sentiment, known as “Uptober,” played significant roles.
  • Further, the $BTCETF token introduced a burn mechanism tied to spot Bitcoin ETF approval, promoting liquidity. Short liquidations, where traders betting against Bitcoin were forced to buy, contributed to a “short squeeze,” with around $94 million worth of short positions liquidated.
  • There’s a growing likelihood of a spot Bitcoin ETF in the USA, potentially driving mainstream investment. Expert forecasts vary, with predictions ranging from $1 million by 2038 to $200,000 by the close of 2024.
  • The surge was a mix of “panic buying” and optimism about potential spot Bitcoin ETF approvals. Understanding the complexities, including ETFs, regulatory progress, and market dynamics, is crucial for navigating the crypto landscape. Bitcoin’s journey is multifaceted, shaped by factors like short squeezes and institutional interest.

What changes have occurred in Bitcoin throughout time?

Economists are currently examining the impact of the hard limit, but on the surface, the price of Bitcoin has climbed dramatically since its inception more than a decade ago. For example, mining a block in 2009 generated 50 bitcoins (but the value was less than). A year later, someone bought two pizzas with 10,000 bitcoins.

The first ‘halving’ took place in 2012, four years after the cryptocurrency’s debut. After that, each block would only produce 25 bitcoins. However, by the end of 2013, one Bitcoin had risen to $200 (about Rs. 14,860).

In 2016, the second halving cut the number of bitcoins to 12.5 and then by half again four years later. As a result, each block mined in 2020 earned 6.25 bitcoins.

Historical Bitcoin Price Trends

  • In 2009-2010, Bitcoin had negligible value, and its first real-world transaction involved 10,000 BTC exchanged for two pizzas. 
  • The year 2011 witnessed a notable spike to $29.6, accompanied by a significant crash. 
  • Subsequent to this, 2012 marked a period of steady growth, characterized by a gradual increase in the price of Bitcoin.
  • The year 2013 was pivotal for Bitcoin, experiencing exponential growth and reaching a value exceeding $1,000. However, this period was also marked by extreme volatility. 
  • The years 2014-2015 were challenging for Bitcoin due to regulatory hurdles and the infamous Mt. Gox scandal, both impacting its price dynamics.
  • In 2016, Bitcoin followed a gradual uptrend, concluding just below $1,000.
  • The year 2017 emerged as a landmark period, witnessing an unprecedented surge in price, reaching nearly $20,000. 
  • However, 2018 marked a correction phase with a substantial 73% price drop.
  • Throughout 2019, Bitcoin’s price displayed signs of stabilization, fluctuating within the range of $3,000 to $4,000. 
  • The year 2020 saw a temporary dip in price caused by the pandemic, but it rebounded, closing the year around $29,000. In 2021, Bitcoin achieved record highs but also encountered heightened volatility.
  • The year 2022 faced a “crypto winter” characterized by a significant price decline influenced by various economic factors and regulatory actions. 
  • In 2023, Bitcoin started to recover, with a trading value over $38,000 as of November. This recovery indicated renewed investor confidence and interest in the cryptocurrency.

What exactly is the situation with Bitcoin’s supply?

Satoshi used a method in the source code to impose a hard cap, or maximum limit, on Bitcoin production of 21 million. The supply of bitcoins is replenished at a set rate of one block every ten minutes. The system design reduces the number of new bitcoins in each block by half every four years.

There are only about 2 million bitcoins left. Experts predict that the last bitcoins will be mined by 2140.

Why should you know how many bitcoins exist and how many are left to mine?

  • Limited Supply: Bitcoin has a maximum supply of 21 million coins, and as of March 2023, more than 19 million have been mined.
  • Remaining bitcoins: There are approximately 2 million bitcoins left to be mined.
  • Impact on Value: Knowing this matters because it affects Bitcoin’s value and future price. When fewer bitcoins are available, demand can rise, increasing the price.
  • Volatility: Decreased supply can lead to price volatility, but if demand doesn’t grow, prices may stay the same or drop.
  • Security: Understanding the mining process is crucial for the security of the Bitcoin network.
  • Informed Decisions: Knowing these facts can help you make better decisions when dealing with Bitcoin as an investment.

So, why is Bitcoin supply limited to 21 million?

As discussed earlier, Bitcoin has a maximum supply of 21 million. This was hard-coded into its protocol by Satoshi Nakamoto. This limit ensures that Bitcoin is scarce and cannot be manipulated like traditional currencies. As more bitcoins are mined, the rate at which new bitcoins are created is reduced over time through a process called halving.

The reason behind the 21 million Bitcoin limit lies in the concept of scarcity, which is a fundamental principle of economics. By limiting the supply of bitcoins, the value of each individual Bitcoin is theoretically increased. This is because as demand for Bitcoin increases, but the supply remains fixed, the price of Bitcoin is likely to increase as well. This is known as the law of supply and demand.

The limit of 21 million bitcoins also ensures that there is no risk of inflation. Inflation is the decrease in the purchasing power of a currency due to an increase in its supply. Governments can manipulate traditional currencies by printing more money, leading to inflation. But with Bitcoin, the supply is fixed, which makes it immune to inflationary pressures.

Bitcoin’s maximum supply of 21 million is also due to the mathematical rules set in the code. This limit is hardcoded into the protocol, meaning it cannot be changed by anyone, including the developers or miners. The maximum supply of 21 million bitcoins will be reached around the year 2140, after which no new bitcoins can be mined. 

The 21 million Bitcoin limit also has important implications for the process of Bitcoin mining. Bitcoin mining is the process by which new bitcoins are created and added to the Blockchain, which is a decentralized ledger that records all Bitcoin transactions. As more bitcoins are mined, the rate at which new bitcoins are created is gradually reduced. This is because the Bitcoin protocol is designed to halve the mining reward every 210,000 blocks. The initial reward was 50 bitcoins per block, but this has been halved several times and is currently at 6.25 bitcoins per block. The reward will continue to be halved until it eventually reaches zero, at which point no more new bitcoins can be created.

The 21 million Bitcoin limit is also critical for network security. Bitcoin’s security is based on a process called proof-of-work, where miners compete to solve complex mathematical problems to add new blocks to the Blockchain. The limited supply of Bitcoin ensures that there will always be a reward for miners, which incentivizes them to continue mining and securing the network.

What happens when all 21 million bitcoins have been mined? 

The short answer is that no more bitcoins can be created. This means that the supply of Bitcoin will be fixed at 21 million, and the value of Bitcoin will be determined entirely by supply and demand. However, the reality is likely to be more complex than this.

Bitcoin transactions will continue to be pooled and processed into blocks, and Bitcoin miners will be compensated, although most likely simply with transaction processing fees.

Bitcoin miners are expected to be affected by Bitcoin reaching its upper supply limit, but how they are affected depends partly on how Bitcoin matures as a cryptocurrency. For example, if the Bitcoin Blockchain processes a large number of transactions in 2140, Bitcoin miners may still be able to profit solely from transaction processing fees.

Even with low transaction volumes and the removal of block rewards, miners can still earn in 2140. This is possible only if Bitcoin is primarily used as a store of value rather than for daily transactions. Miners can charge hefty transaction fees to process big-value transactions or vast batches of transactions, with more efficient “layer 2” Blockchains like the Lightning Network assisting daily Bitcoin spending.

However, if Bitcoin mining becomes unprofitable in the absence of block rewards, the following undesirable consequences may occur:

  • Miners may create cartels in an attempt to gain control of mining resources and command more outstanding transaction fees.
  • Selfish mining occurs when miners work together to keep new legitimate blocks hidden and then release them as orphan blocks that the Bitcoin network has not confirmed. This method can lengthen block processing periods and ensure that when new blocks are finally issued to the Blockchain, they are accompanied by hefty fees.

What will the network’s response be?

Bitcoin’s network is an essential aspect. Any cryptocurrency is built on a distributed ledger paradigm.

If the network’s transaction volume grows in the future, transaction speeds may slow. The architecture of Bitcoin is more concerned with accuracy and integrity than with speed.

There’s a potential that Bitcoin will become a reserve asset if the quantity of transactions in the network declines. As a result, small retail traders will be pushed out, and prominent institutional players will take their place, perhaps raising transaction fees and making trading more costly.

How is the limited supply of bitcoins achieved?

How is the limited supply of bitcoins achieved?

Bitcoin’s limited supply is a unique feature that sets it apart from traditional fiat currencies. The limited supply is enforced by the Bitcoin protocol, which specifies that only 21 million bitcoins will ever exist.  Bitcoin’s limited supply is enforced through a combination of mining and the Bitcoin halving process. Bitcoin mining allows the creation of new bitcoins.

Mining is a process that involves using powerful computers to solve complex mathematical problems, which are used to verify and add new transactions to the Bitcoin Blockchain. When a miner successfully solves a problem, they are rewarded with a certain number of bitcoins, which are added to the Bitcoin supply. The reward for mining a block of Bitcoin transactions started at 50 bitcoins and is halved approximately every four years through a process called Bitcoin halving.

The first Bitcoin halving occurred in November 2012, reducing the mining reward from 50 bitcoins to 25 bitcoins. The second halving occurred in July 2016, reducing the reward from 25 bitcoins to 12.5 bitcoins. The most recent halving took place in May 2020, reducing the reward from 12.5 bitcoins to 6.25 bitcoins.

The halving process is an essential part of the Bitcoin protocol, as it helps to maintain a predictable supply of bitcoins and prevent inflation. By reducing the mining reward over time, the rate at which new bitcoins are added to the network slows down, eventually reaching zero once the total supply of 21 million bitcoins is reached.

It is worth noting that the actual number of bitcoins in circulation is currently lower than the total supply of 21 million. This is because some bitcoins have been lost due to people losing access to their private keys, which are necessary to access and spend bitcoins. Estimates suggest that around 4 million bitcoins have been lost, reducing the total supply to around 17 million.

Bitcoin Supply Mechanics

Genesis Block and Satoshi’s Vision

Bitcoin’s journey began on January 3, 2009, with the creation of the Genesis block by its mysterious creator, Satoshi Nakamoto. This inaugural block, known as “Block 0,” marked the birth of the Bitcoin Blockchain. What made it unique was that it contained no preceding blocks, making it the foundation upon which the entire Blockchain rests.

Satoshi Nakamoto’s vision was clear: to create a peer-to-peer electronic cash system that would operate independently of central authorities, like banks and governments. To achieve this, Satoshi introduced a groundbreaking concept – the Blockchain. This public ledger records all Bitcoin transactions, ensuring transparency and security.

A Brief Look at the Mining Process and Its Significance

Mining is at the heart of Bitcoin’s supply mechanics. Unlike traditional currencies that are printed by central banks, bitcoins are mined by individuals and groups known as miners. These miners perform complex mathematical calculations to validate and record transactions on the Blockchain.

The mining process serves two crucial purposes. First, it secures the network by preventing double-spending and fraud. Miners must compete to solve mathematical puzzles, and the first to solve it gets the privilege of adding a new block to the Blockchain. This competition ensures the honesty and integrity of the system.

Second, mining is the mechanism through which new bitcoins are created and introduced into circulation. Approximately every ten minutes, a miner successfully adds a block to the Blockchain and is rewarded with a set number of newly minted bitcoins. This process, known as the “block reward,” reduces over time through a programmed halving event, ultimately capping the total supply at 21 million bitcoins.

The Crucial Role of Cryptographic Puzzles in Securing the Network

Bitcoin’s security hinges on cryptographic puzzles. Transactions on the Bitcoin network are protected by advanced cryptographic algorithms that ensure their authenticity and privacy. Public and private keys are used to sign and verify transactions, making it nearly impossible for unauthorized parties to alter the transaction history.

Additionally, the proof-of-work (PoW) consensus algorithm, which involves solving complex cryptographic puzzles, ensures network security. Miners must invest computational power to find a solution, making it prohibitively expensive for malicious actors to manipulate the Blockchain.

Factors affecting the number of bitcoins left to mine

Mining Difficulty: What is it and how is it adjusted?

Before we understand how mining difficulty is adjusted, it is important to understand how is Bitcoin mined? Bitcoin mining is a critical process that involves using powerful computers to solve complex mathematical problems. These problems are used to verify and add new transactions to the Bitcoin Blockchain, and the process of solving them is called mining. Here is a simplified explanation of how Bitcoin is mined?

Transactions: People all around the world make transactions with Bitcoin. These transactions are like the digital coins changing hands.

Block: Bitcoin transactions are grouped together into a “block.” Think of it as a digital container that holds these transactions.

Miners: Miners are like the digital workers who make this whole process happen. They use powerful computers to solve complex math problems. To understand “how a Bitcoin is mined?” it is important to understand how these miners solve complex puzzles to mine a Bitcoin.

Proof of Work: The math problems or puzzles that the miners solve require a lot of computing power. This whole process is called “Proof of Work.” It is like a race to solve the problem first.

Adding to the Blockchain: When a miner solves the problem, they get to add the new block of transactions to the “Blockchain.” The Blockchain records all Bitcoin transactions ever made. It means that you can find the record of a mined Bitcoin at any time on the Blockchain.

Reward: As a reward for their hard work, the miner who solves the problem first gets some new bitcoins. The miner also gets transaction fees from the transactions in the block they added.

Repeat: This process keeps repeating, about every 10 minutes. New blocks are added to the Blockchain, more bitcoins are created, and the network keeps running.

However, as more miners join the network, the difficulty of solving these problems increases, making it more challenging to mine new bitcoins. This is where the concept of mining difficulty comes into play.

Mining difficulty refers to the difficulty level of solving the mathematical problems necessary to mine new bitcoins. It is measured using a metric called the “difficulty target,” which is a 256-bit number that the miners must try to match. The lower the difficulty target, the harder it is to mine new bitcoins.

The process of adjusting the mining difficulty is known as the difficulty adjustment algorithm (DAA). The DAA is designed to ensure that the average time between blocks remains at 10 minutes, regardless of changes in the hash rate. The Bitcoin network achieves this by increasing or decreasing the difficulty target by a factor of 4, depending on whether the previous 2016 blocks were mined too quickly or too slowly.

This adjustment is done automatically by the Bitcoin network to maintain a constant rate of new Bitcoin production. The adjustment is based on the total computing power of the Bitcoin network, or the network hash rate. If the hash rate increases, the difficulty target is increased, making it harder to mine new bitcoins. Conversely, if the hash rate decreases, the difficulty target is decreased, making it easier to mine new bitcoins.

The adjustment of mining difficulty is crucial to the functioning of the Bitcoin network. If the difficulty level remains too high, it could discourage miners from continuing to mine bitcoins, as the cost of electricity and hardware would be too high relative to the mining rewards. On the other hand, if the difficulty level remains too low, it could result in an oversupply of new bitcoins, which could lead to inflation and a loss of value for the currency.

The recent increase in the mining difficulty is an indication of the growing popularity and success of Bitcoin. As more miners join the network, the difficulty level increases, making it more challenging to mine new bitcoins. However, this also means that the network is becoming more secure, as it becomes harder to conduct a 51% attack on the network.

Bitcoin’s mining difficulty rose by nearly 5.56% in 2022, hitting a lifetime high of 30 trillion. This increase in difficulty means that it takes more computational power to validate a block of transactions and earn the associated reward of newly mined bitcoins.

Bitcoin mining difficulty has increased by more than 20,000 times since the first block was mined in 2009, which demonstrates the exponential growth of the network’s hash rate. This growth has been fueled by the development of specialized hardware known as application-specific integrated circuits (ASICs), which are optimized for the specific computations required for Bitcoin mining.

Halving events and their impact on the mining reward

As we already discussed, halving events are programmed into the Bitcoin protocol to control the supply of bitcoins. However, these events have a significant impact on mining rewards. When a halving event occurs, the reward that miners receive is cut in half, which reduces their profitability. This can cause some miners to stop mining, especially those with outdated equipment that is not efficient enough to mine profitably.

This reduction in mining rewards can have both positive and negative effects on the mining industry and the Bitcoin network as a whole.

On the negative side, halving events can cause some miners to stop mining, particularly those with older equipment that is not efficient enough to mine profitably. This is because the cost of mining, including electricity and hardware, can exceed the value of the rewards received, making it unprofitable to continue mining. This can lead to a reduction in the overall mining power of the network, which can in turn slow down transaction processing times and make the network less secure.

However, on the positive side, halving events can also lead to an increase in the price of Bitcoin. This is because halving events reduce the supply of new bitcoins, and if demand for the cryptocurrency remains constant, the price should increase to compensate for the reduced supply. This increase in price can offset the reduction in mining rewards, and some miners may continue to mine even after a halving event.

In fact, historical data shows that halving events have often coincided with significant increases in the price of Bitcoin. For example, the first halving event in 2012 was followed by a year-long bull run that saw the price of Bitcoin increase. Similarly, the second halving event in 2016 was followed by another bull run.

The impact of halving events on the price of Bitcoin can also be influenced by a variety of external factors, such as changes in regulatory policies, technological developments, and global economic conditions. Therefore, while halving events can have a significant impact on the Bitcoin network, it’s important to consider a range of factors when evaluating their impact on mining rewards and the price of Bitcoin.

The Role of “Coinbase” Transactions 

In the world of Bitcoin, the term “coinbase” may not refer to a popular cryptocurrency exchange but instead holds a crucial role in the creation of new bitcoins and, consequently, the overall Bitcoin supply.

A coinbase transaction is the initial transaction in every newly mined Bitcoin block. Its primary purpose is to reward the miner who successfully adds a new block to the Blockchain. In this transaction, miners receive newly created bitcoins as a reward for their efforts in securing and maintaining the Bitcoin network.

The significance of coinbase transactions lies in their role as the genesis of fresh bitcoins. When miners solve complex mathematical puzzles to validate transactions and create a new block, they earn this reward. Initially, during Bitcoin’s early days, the reward was substantial, starting at 50 bitcoins per block.

However, Bitcoin has a built-in mechanism to control its supply and maintain scarcity – the halving process. Approximately every four years, the reward in coinbase transactions is halved. This means that the number of new bitcoins created in each block decreases by 50%.

For instance, the first halving occurred in November 2012, reducing the reward from 50 to 25 bitcoins. Subsequent halvings in 2016 and 2020 further reduced it to 12.5 and 6.25 bitcoins, respectively. This process will continue until the maximum supply cap of 21 million bitcoins is reached, estimated around the year 2140.

The connection between coinbase transactions and Bitcoin’s total supply is direct. The newly created bitcoins in each coinbase transaction contribute to the growing supply. Over time, as halving events occur, the rate at which new bitcoins enter circulation decreases significantly.

Analyzing the historical effects of halving 

The historical data on Bitcoin halving events provides valuable insights into their impact on miner incentives and the cryptocurrency’s price.

When a halving occurs, miners face a reduction in their income since they receive fewer bitcoins for their efforts. This might lead to some miners exiting the network, especially those with high operational costs. However, it’s important to note that Bitcoin’s price tends to experience upward pressure in the months leading up to and following a halving event. This price increase can offset the reduced block rewards for miners.

Miners who remain in the network after a halving often do so with the expectation that the higher Bitcoin price will compensate for the reduced rewards. This belief in the potential for future price appreciation is a key factor in sustaining the security and stability of the Bitcoin network.

Investors and traders also closely monitor Bitcoin halving events. Historical data shows that these events have historically been associated with bull markets and significant price rallies. This phenomenon can be attributed to the reduced supply of new bitcoins entering the market, which can create scarcity and drive up demand.

To understand the impact of Bitcoin halving events on miner incentives and the cryptocurrency’s price, let’s examine the latest statistics and facts:

Miner Incentives

We have already answered the question “how is bitcoin mined?” Now let’s talk about the miner incentives:

  • After the first halving in November 2012, the Bitcoin hash rate experienced a 30% decline. However, it rebounded swiftly within a few months and proceeded to reach new all-time highs in the subsequent years.
  • Following the second halving in July 2016, a similar pattern emerged, with the Bitcoin hash rate decreasing by approximately 15%. Yet, just as before, it bounced back within a few months, continuing its upward trajectory.
  • After the third halving in May 2020, there was a temporary drop of about 20% in the Bitcoin hash rate. Remarkably, recovery was even faster than in previous halving events, and the hash rate reached new highs within a matter of weeks.

Bitcoin’s Price

  • In the year following the first halving, Bitcoin’s price surged by an astonishing 1,000% or more. This dramatic increase captured the attention of both investors and enthusiasts alike.
  • Following the second halving, which took place in July 2016, Bitcoin’s price saw an even more remarkable increase, exceeding 1,500% in the year that followed. This meteoric rise solidified Bitcoin’s status as a digital asset with immense potential.
  • After the third halving in May 2020, Bitcoin’s price surged by over 500% within a year. This robust performance underscored the continued interest and confidence in the cryptocurrency.

Projected Timelines for Mining the Remaining bitcoins

Understanding the timeline for mining the remaining bitcoins requires a closer look at the current rate of new Bitcoin creation through mining and the upcoming halving events.

As of now, the rate of new Bitcoin creation is set at 6.25 BTC per block, which equates to approximately 1 block every 10 minutes. This means that roughly 900 new BTC are generated daily. However, this rate is not static.

Bitcoin’s ingenious design incorporates a system of halving events that occur approximately every 210,000 blocks, or roughly every four years. The next anticipated halving is scheduled for April 2024. During this event, the block reward will be slashed in half, reducing it to 3.125 BTC.

With a total cap of 21 million bitcoins, these halving events play a pivotal role in shaping the timeline for mining the remaining bitcoins. They lead to a gradual reduction in the rate of new coin creation, ultimately approaching zero.

So, when can we expect the last Bitcoin to be mined? While pinpointing an exact date is impossible, it is estimated that all 21 million bitcoins will be mined by the year 2140. This extended timeline underscores the deliberate pace at which new bitcoins are introduced into circulation, reinforcing the cryptocurrency’s scarcity and long-term value.

It’s worth noting that the profitability of Bitcoin mining can fluctuate based on several factors. These include the price of Bitcoin itself, the cost of electricity required for mining, and the ever-changing mining difficulty. Miners need to navigate these variables as they participate in the network, making it a dynamic and competitive endeavor.

Bitcoin Distribution Among Holders

Bitcoin’s distribution started with its creator, Satoshi Nakamoto, who mined the first bitcoins. It is estimated that Nakamoto holds around 1 million bitcoins, but their identity remains a mystery. This initial accumulation significantly impacts the distribution. The distribution of Bitcoin among its holders has long been a subject of scrutiny and analysis, with ongoing debates about the extent of decentralization in the cryptocurrency’s ownership landscape. Let’s dive into the latest data to gain a deeper understanding.

Top 100 Addresses: A Dominant Force

As of September 26, 2023, Blockchain data sourced from BitInfoCharts reveals that the top 100 richest Bitcoin addresses collectively control a substantial 58.21% of the total Bitcoin supply. This concentration highlights that a mere 0.01% of Bitcoin holders possess nearly 60% of the entire BTC supply.

However, it’s crucial to exercise caution when interpreting this data. Not all of these top addresses necessarily belong to individual whales. Some may be associated with cryptocurrency exchanges, custodians, or institutional entities. Additionally, certain addresses may remain dormant or inactive, which can skew the distribution perception.

Beyond the Top 100: A More Decentralized Picture

When we venture beyond the top 100 addresses, the distribution of Bitcoin exhibits signs of increasing decentralization. The subsequent tier of 10,000 addresses collectively holds approximately 24% of the Bitcoin supply. Moving further down the ladder, the next 100,000 addresses control roughly 11% of the cryptocurrency’s total supply.

The Overall Landscape

In sum, the distribution of Bitcoin appears to be gradually moving toward a more decentralized pattern over time. Nonetheless, it’s evident that a significant proportion of Bitcoin remains concentrated in the hands of a relatively small number of large holders.

Here’s a breakdown of the Bitcoin distribution among holders as of September 26, 2023:

  • Top 100 Addresses: 58.21%
  • Next 10,000 Addresses: 24%
  • Next 100,000 Addresses: 11%
  • Remaining Addresses: 7%

This data reflects the ongoing evolution of Bitcoin’s distribution landscape, highlighting both its potential for decentralization and the presence of notable concentrations in the hands of key stakeholders.

The influence of Bitcoin whales and their impact on market sentiment

Bitcoin whales are large holders of the cryptocurrency who possess the potential to impact the market in substantial ways. Their actions, such as buying or selling large quantities of Bitcoin, can lead to price volatility and affect other investors’ sentiment.

  • Market Volatility: Bitcoin whales, due to their substantial holdings, have the power to induce market volatility. When a whale decides to execute a large sell order, it can trigger a significant drop in the cryptocurrency’s price. Conversely, a substantial buy order can lead to rapid price increases. This volatility can create both opportunities and risks for other investors.
  • Fear and Greed: Bitcoin whales’ actions often fuel emotional responses among smaller investors. When whales make significant moves, it can generate fear or greed in the market. For example, a sudden sell-off by a whale may cause panic selling among retail investors, resulting in a price crash. On the flip side, a whale’s strategic buying can spark optimism and drive up prices as others rush to join the rally.
  • Long-Term Impact: Some Bitcoin whales adopt a long-term perspective and hold their assets for extended periods. These “HODLers” (a term derived from a misspelling of “hold”) contribute to the cryptocurrency’s overall stability. Their willingness to weather short-term fluctuations can counterbalance the influence of more short-term-oriented whales, providing a degree of equilibrium to the market.

Challenges in Calculating Supply

Calculating Bitcoin’s supply isn’t as straightforward as it may seem. The decentralized nature of Bitcoin poses several challenges in this regard.

Bitcoin operates on a decentralized ledger, which means there is no central authority or database that stores all supply-related data. Instead, every transaction and newly mined Bitcoin is recorded on a public ledger known as the Blockchain. While this decentralization is one of Bitcoin’s strengths, it also makes it challenging to maintain an accurate count of the total supply.

Another factor to consider is Bitcoin halving events. Approximately every four years, the rewards for mining new bitcoins are halved. This event reduces the rate at which new bitcoins are created, making it crucial for accurate supply calculations.

Factors affecting the accuracy of supply data

Several factors influence the accuracy of data related to Bitcoin’s supply. These include:

  • Mining Rewards: The process of mining new bitcoins and receiving rewards is fundamental to Bitcoin’s supply. Miners secure the network and are rewarded with newly created bitcoins and transaction fees. Changes in mining activity can impact the supply rate.
  • Transaction Fees: Transaction fees play a role in miners’ incentives. When the demand for Bitcoin transactions is high, miners can earn more from fees, influencing their decision to continue mining.
  • Lost bitcoins: Perhaps one of the most intriguing factors is the concept of lost bitcoins. Over the years, many bitcoins have been lost due to forgotten passwords, misplaced wallets, or other reasons. These lost bitcoins are unrecoverable, affecting the overall supply.

The difficulty of tracking lost bitcoins and their implications

Lost bitcoins, while unfortunate for their owners, have significant implications for the cryptocurrency ecosystem. As mentioned earlier, these lost coins are irrevocably removed from circulation. Estimates suggest that a substantial number of bitcoins may never be accessed again. This scarcity can drive up the value of existing bitcoins and has implications for long-term investment strategies.

Transparency is paramount in reporting Bitcoin’s supply. Various Blockchain explorers and data providers offer real-time information about the total supply, circulating supply, and more. This transparency builds trust among users and investors, ensuring they can make informed decisions.

Environmental Concerns

Bitcoin mining is the process of verifying and adding new Bitcoin transactions to the Blockchain. This task is accomplished by powerful computers that solve complex mathematical problems. However, this process consumes a substantial amount of energy due to the constant operation of these computers and their significant electricity usage.

Facts and Stats About Bitcoin’s Energy Consumption:

  • Bitcoin mining consumes approximately 110 terawatt-hours (TWh) of electricity per year. To put this into perspective, it surpasses the annual electricity consumption of many countries, including Norway and the Netherlands.
  • Bitcoin mining contributes to about 0.6% of the world’s total electricity consumption.
  • It’s estimated that Bitcoin mining generates around 65 megatons of carbon dioxide emissions each year, which is comparable to the annual emissions of Greece.
  • The energy consumption of Bitcoin mining has been on a rapid rise. In 2021, it consumed about 62 TWh of electricity, signifying a more than 70% increase in just one year.

Why Bitcoin Mining Consumes So Much Energy:

The energy-intensive nature of Bitcoin mining can be attributed to the Bitcoin network’s design. It relies on a proof-of-work consensus mechanism where miners compete to solve complex mathematical problems. The first miner to successfully solve the problem is granted the opportunity to add the next block to the Blockchain and receives a block reward in Bitcoin.

The difficulty of these mathematical problems is adjusted periodically to maintain a consistent block-adding rate. Consequently, as more miners join the network, the problems become more challenging, demanding even greater energy consumption to mine Bitcoin.

Efforts to Reduce Bitcoin Mining’s Energy Consumption

However, no additional bitcoins will be released after the 21-million coin cap is met, regardless of how Bitcoin evolves. The impact of reaching this supply limit is most likely to be felt by Bitcoin miners; however, the Bitcoin investors could suffer as well.

If you’re still in the fog about Bitcoin and don’t know where to begin, check for Bitcoin professionals. However, if you aspire to become a professional then you can enroll into some cryptocurrency course. Blockchain council has got all the in-demand Blockchain related certification courses for you. 

  • The 21 million Bitcoin supply limit is significant because it ensures that Bitcoin is deflationary.
  • This means Bitcoin’s value is likely to increase over time as the supply decreases.
  • It distinguishes Bitcoin from fiat currencies, which are usually inflationary and lose value over time.
  • Once all bitcoins are mined, miners won’t receive block rewards for verifying transactions.
  • Instead, they’ll earn transaction fees, which are currently a small part of total mining rewards.
  • Transaction fees could rise significantly with increasing demand for Bitcoin transactions.
  • As of March 2023, there are over 19 million bitcoins in circulation, out of a total supply of 21 million. 
  • This means that around 90% of all bitcoins have already been mined.
  • How long it takes to mine one Bitcoin is determined by the size of the block reward or how many new bitcoins are paid to crypto miners for generating a new Bitcoin block. 
  • Every 10 minutes, a new block is generated, with the current block reward of 6.25 bitcoins.
  • When the Bitcoin supply reaches 21 million, it will abolish mining fees. 
  • Instead of a mix of block rewards and transaction fees, miners are more likely to receive money solely from transaction processing fees.
