The market cap of a cryptocurrency: what is it and what analyses can be drawn from it?
When you wish to invest in cryptocurrencies, understanding certain concepts allows you to have a more technical and precise overview of the sector. The market cap, also referred to as market capitalization, refers to information that characterizes every cryptocurrency, whether it is Bitcoin, the queen of cryptos, or a newcomer like the meme coin Pepe. The market cap can notably serve as a baseline to scrutinize the state of a given crypto-asset, or to analyze the market as a whole.
Definition of Market Cap: How to Understand the Concept of Market Capitalization?
When it comes to investing, it is paramount to be able to understand the status of a given asset based, among other things, on the trust it inspires in other investors. In science or technology, for instance, the number of people who have adopted an innovation or a tool provides valuable insights into its perceived quality or relevance. For an asset, however, the number of holders would constitute too flimsy a factor: to a much greater extent, it would be interesting to know how much capital investors are placing into this asset. This is the exact information conveyed by the market cap.
Why, then, do we also speak of market capitalization? More precisely, the market cap (or market capitalization) designates the cumulative value of all units of an asset in circulation at a specific time. These circulating units are held by investors. In the case of a public company, the market capitalization indicates what it is worth at a given moment, based on the shares held by various people on the market and the value of each share.
In this respect, the market cap represents a reliable indicator for providing guidance on the health of an asset. The market cap of a cryptocurrency illustrates its current situation on the markets, determined by the trust it inspires in crypto investors. The market valuation of Bitcoin ($2,315 billion), Ethereum ($543 billion), or XRP ($180 billion) reaching multi-billion-dollar thresholds testifies directly to their global credibility.
How Is Market Cap Calculated and How Can It Be Leveraged in Analyses?
The formula for calculating market cap accounts for the capacity of this data point to serve as an analysis parameter for a cryptocurrency. This formula consists of a simple multiplication: value of one unit of cryptocurrency X the number of tokens / coins in circulation.
By extrapolation, when analyzing the cryptocurrency sector as a whole, the sum of the individual market caps equals the total market capitalization of the sector. A high market capitalization indicates that investors have chosen to commit significant amounts of capital to the ecosystem.
At the scale of a single cryptocurrency, the lower its price for the same number of units in circulation, the lower its market cap will be. In parallel, for every new buyer triggering the issuance of an additional token or coin, for a fixed price, the market capitalization increases. These rules, however, remain theoretical: in practice, the market evolves constantly.
The market cap obeys the law of supply and demand. The behavior of the market cap over time can provide vital information and help an investor establish their strategy. When investors choose to hold their bitcoins, their ethers, or their Solana coins (SOL), such an attitude signals confidence in the asset. Its value will then tend to grow, and the market capitalization will move in the same direction.
Conversely, when more and more holders of a crypto choose to sell, it is generally an indication of a loss of confidence. Even though the number of units in circulation will not drop, a price decrease will occur, which will lead to a reduction in the market cap.
What Happens When a Market Cap Plummets or Surges Suddenly? (Illustration with Terra Luna)
The entire crypto ecosystem was shaken by the crash of Terra Luna in May 2022. The main cryptocurrency of the project, LUNA, saw its value drop from over 100 dollars to less than 1 dollar within a few hours. While the causes of this situation are numerous, we will focus here on its effect on the market cap.
With the rapid fall of LUNA, the market capitalization also plummeted. Driven by panic, many investors opened short or selling positions, which added to the loss of value. But the reverse occurs with other cryptos: rapid rise, high demand, and continued upward momentum over a short period.
That is why analyzing the market cap alone is obviously not enough! When you observe sudden changes, do not rush. First, inform yourself about the underlying fundamental events driving them. You will then make more thoughtful choices.
FAQ
What is the market cap of a cryptocurrency and what does it mean concretely?
The market cap, or market capitalization, designates the cumulative value of all units of an asset in circulation at a given time. Rather than simply counting the number of holders of a token, this indicator measures the totality of the capital placed by investors into a cryptocurrency. It is a reliable indicator that illustrates the current status of an asset on the markets and accounts for the level of confidence it inspires.
How is the market cap of a crypto-asset calculated?
The calculation formula relies on a very simple multiplication: the current value of one unit of the cryptocurrency multiplied by the number of tokens or coins in circulation. By extrapolation, the sum of the capitalizations of each asset yields the global market cap of the entire crypto market.
What is the analysis to be made if the market cap of a crypto-asset increases or decreases?
The behavior of the capitalization is dictated by the law of supply and demand. An increase signals that investors are holding their tokens or buying new ones, which pushes the value and the market cap upward. Conversely, mass selling drives the price down, leading to an automatic reduction in the market cap, which materializes a loss of confidence.
Why is analyzing the market cap alone not enough to make an investment decision?
The market cap reflects an instantaneous situation and can undergo violent movements, as seen during the Terra Luna crash in May 2022 where the capitalization plummeted in a matter of hours. Observing a sudden variation is not enough: it is indispensable to inform oneself about the fundamental underlying causes at the origin of these movements to make thoughtful choices.
