How many bitcoins are there

The total amount of Bitcoin is constant at 21 million, and this fact set by Satoshi Nakamoto code gives Bitcoin a unique value attribute. Unlike unlimited fiat currencies, Bitcoin’s scarcity gives it anti-inflation potential and is similar to precious metals such as gold. Its issuance mechanism is gradually released through "mining" and the reward is halved every four years, and it is expected to reach the total upper limit by around 2140. Although the actual circulation volume is less than the total volume, the total volume limit of 21 million coins is the core value support of Bitcoin, and it also makes it a highly-watched digital asset. Understanding the limit on the total amount of Bitcoin is crucial for investors to make rational decisions.

As a digital asset, one of the most prominent features of Bitcoin is that its total amount is fixed, which is fundamentally different from traditional currencies. So, how many Bitcoins are there? The answer is: 21 million pieces.

This number is not set at will, but is written to death by Bitcoin creator Satoshi Nakamoto in the code. This design aims to imitate scarce resources such as gold, ensure the scarcity of Bitcoin, and prevent inflation.

The importance of total limit

The total amount of Bitcoin is of the following significance:

1. Scarcity: Unlike traditional currencies that can be issued indefinitely, the amount of Bitcoin is limited, which makes it scarce, similar to precious metals such as gold. This scarcity is the basis of Bitcoin’s value.
2. Anti-inflation: Due to the fixed total volume, Bitcoin will not depreciate its value due to over-issuance. This makes Bitcoin a potential anti-inflation tool, especially when traditional currencies face inflationary pressures.
3. Predictability: The total amount of Bitcoin and issuance schedule are open and transparent, and anyone can verify it. This predictability increases trust in it.

How to reach the upper limit of total quantity

Bitcoin is not a one-time issuance, but is gradually released to the market through "mining". Mining is a computationally intensive process where miners get Bitcoin rewards by solving complex mathematical puzzles to verify transactions and create new blocks.

Over time, the rewards of Bitcoin will gradually decrease, halving every four years or so. This mechanism makes the issuance of Bitcoin slower and slower. It is expected that by around 2140, all Bitcoins will be mined and reached the total amount limit.

Flow volume and total volume

It should be noted that the total amount of Bitcoin is 21 million, but this does not mean that 21 million Bitcoins are currently circulating in the market. Due to various reasons, such as loss of private keys, long-term holding, etc., a portion of Bitcoin may never be able to enter circulation. Therefore, the actual number of Bitcoins circulating in the market is less than 21 million.

Summarize

The total amount of Bitcoin is set to 21 million, which is an important feature that ensures the scarcity, inflation resistance and predictability of Bitcoin. Understanding Bitcoin’s total volume limits helps us better understand its value and make smarter investment decisions. Although Bitcoin's circulation will continue to change in the future, the total upper limit of 21 million will remain the same, which is the cornerstone of Bitcoin.
