In today's digital economy era, Bitcoin, as a cryptocurrency, has attracted much attention, and its circulation has always been the focus of the market and investors. How many Bitcoins are in circulation? This question concerns many investors and digital currency enthusiasts. Let's explore the circulation of Bitcoin in depth and reveal the mystery of digital currency.

The circulation of Bitcoin refers to the total amount of Bitcoin that has been issued and circulated in the market. According to the latest data, as of now, the total circulation of Bitcoin has reached nearly 21 million. This number is not static, but gradually increases with the continuous progress of Bitcoin mining. The total issuance of Bitcoin is set at an upper limit of 21 million, which is also one of the biggest differences between Bitcoin and traditional currencies.

The issuance rules of Bitcoin are implemented through mining. Mining refers to the process of verifying transactions and introducing new Bitcoins into the market by calculating complex algorithms. The difficulty of mining gradually increases, which means that the difficulty of mining Bitcoin is also increasing. This mechanism ensures the scarcity and value stability of Bitcoin, which has attracted the favor of many investors.

In addition to mining, the circulation of Bitcoin is also affected by other factors, such as the trading volume of exchanges and the trading behavior of coin holders. With the popularity of Bitcoin around the world, more and more people are beginning to accept Bitcoin as a means of payment, which has also promoted the circulation of Bitcoin. In some countries, Bitcoin has been officially recognized as legal tender, which will undoubtedly have a positive impact on the circulation of Bitcoin.

It is worth mentioning that the circulation of Bitcoin is not just a simple number. Behind it is the development trend and future direction of the entire digital currency field. With the continuous development and innovation of blockchain technology, digital currency will be applied in a wider range of fields. As the leader of digital currency, the increase in the circulation of Bitcoin will promote the development of the entire digital currency market.

In the future, as the circulation of Bitcoin gradually increases, its status and role in the financial field will become more important. As a decentralized digital currency, Bitcoin is not controlled by any government or institution, and will bring new changes and challenges to the financial system. Investors and market participants need to pay close attention to the changes in the circulation of Bitcoin in order to seize market opportunities and realize wealth appreciation.

In general, the circulation of Bitcoin is a crucial indicator in the digital currency market. It not only reflects the supply and demand relationship of Bitcoin in the market, but also directly affects the price trend and market performance of Bitcoin. As the digital currency market continues to develop and improve, the circulation of Bitcoin will continue to be one of the important indicators for market research and investment analysis, leading the future development direction of digital currency. May we witness the glory of the digital currency era and explore the infinite possibilities of digital currency.

Before answering this question, let me first tell you what the circulation quantity is. The circulation quantity refers to the total amount of stocks that can be traded in the Shanghai and Shenzhen stock markets. The circulation quantity mentioned in this article is simply the total amount of Bitcoin in the digital currency trading market. For digital currencies, any digital currency has a circulation quantity, even the most coin king Bitcoin is no exception. After understanding the meaning of the circulation quantity, let's return to the topic. How many Bitcoins are in circulation? Below, I will summarize the circulation quantity of Bitcoin for you.

 How many Bitcoins are in circulation?

There are currently 17,890,162.5 Bitcoins in existence. This number changes approximately every 10 minutes when a new block is mined. Now, each new block adds 12.5 Bitcoins to the circulation.

Since 1.5 million Bitcoins are almost guaranteed to be lost, we can estimate the actual supply today with some degree of accuracy. Despite the claim that the total upper limit is 21 million, a total of up to 19.5 million Bitcoins can exist.

CoinGecko data shows that so far, the number of Bitcoins that have been mined. The number of Bitcoins in existence today is just under 16.8 million. There are also other factors at work.

First, we cannot accurately predict how many tens of thousands of Bitcoins have been lost over the past decade. In addition, Bitcoin has barely moved from Mt. Gox and Bitfinex. The owners of the PlusToken Ponzi scheme are an exception, moving large chunks of their loot onto the exchange. This estimate does not provide an exact count of the number of lost coins, but it can help determine a lower bound on the total number of lost coins and an upper bound on the total supply.  Why is the total number of Bitcoins 21 million? 1. Bitcoin was designed by Satoshi Nakamoto to be capped at 21 million. By limiting its maximum supply and slowing the rate at which new Bitcoins are produced, Satoshi Nakamoto hoped that each unit of Bitcoin (currently called a "satoshi") would appreciate in value over time. According to an email shared by Satoshi Nakamoto and Bitcoin Core contributor Mike Hearn, Satoshi Nakamoto believed that if 21 million BTC were used by a certain part of the world economy, 0.001 BTC would be worth about 1 euro. This prediction came true in 2013, when Bitcoin first broke the 1,000 euro price point; today, each 0.001 BTC is worth nearly 8.25 euros. 2. Although Satoshi compared the price of Bitcoin to the Euro in his email, some simple math suggests that he may have had a much grander vision for Bitcoin, which explains why the 21 million cap was chosen.

At the time of Bitcoin’s creation, the world’s money supply was about $21 trillion. This number is called the M1 money supply and is made up of the total value of all physical money in the world, including cash, gold, checks, and so on.

If Bitcoin were to develop into the single world currency (replacing all the currencies included in the M1 number), then each BTC would be worth $1 million. Since there are 100 million Satoshis in each Bitcoin, each Satoshi would be worth $0.01.

If Satoshi didn’t mean it, it’s an amazing coincidence that these numbers are so closely aligned to the truth.

3. Although the M1 money supply replacement theory may be the most plausible reason for Satoshi to choose 21 million as the upper limit of Bitcoin, there is another (and perhaps simpler) explanation.

Looking at the parameters used to control Bitcoin's supply, it's clear that the 21 million Bitcoin figure enables the network to ensure that blocks are mined within a regular time period (10 minutes).

It also ensures that the number of Bitcoins paid to miners as block rewards decreases over time as the maximum supply approaches its upper limit. It turns out that the parameters set by Satoshi for this inevitably lead to a maximum of 21 million BTC being produced.

4. The Bitcoin Core code currently adjusts the mining difficulty to ensure that a new block is mined every 10 minutes on average, regardless of the network's hash rate. Based on this feature, 210,000 blocks should be mined in every four-year cycle, after which the block reward will be halved.

The first cycle saw 50 BTC produced per block; this number was halved to 25BTC/block in 2012, and then again to 12.5BTC/block in 2016. Following the 2020 halving, it currently sits at 6.25/BTC block.

If you calculate forward, you will find that the sum of the block rewards for each cycle is equal to 100 (50+25+6.25+3.125+1.5625+.... and so on). By multiplying this number by the 210,000 blocks/cycle diagram, you can get the maximum supply of 21 million.

Through the above introduction, I believe that everyone has already understood how many Bitcoins are in circulation. The editor of the Coin Circle kindly reminds investors that whether they invest in Bitcoin or not, they must have a basic understanding of the circulation quantity, market value, and how many exchanges the digital currency is listed on, and then through the white paper of the digital currency, have a basic understanding of the digital currency, and finally determine whether to invest in the digital currency. If you want to know more about the relevant knowledge, you can pay attention to the Coin Circle. The editor of the Coin Circle will continue to update the relevant reports later!
