What Is Market Cap in Crypto, and Why Does It Matter?

Crypto markets can be complex, especially if you’re new to the space. There will be a number of terms and metrics you'll encounter while you evaluate different tokens and one of the most common ones is "market cap." But what does it mean when comparing different tokens, and how can it be useful?

This article explains what crypto market cap is, how it’s calculated, and how it can be used to compare crypto assets. We'll also discuss different types of metrics and address how each value relates to circulating versus total supply. By the end, you should have a clearer understanding of how this metric is commonly used when comparing crypto 

Market capitalization (or “market cap”) is a commonly used metric for estimating the aggregate market value of a cryptocurrency based on its price and circulating supply.It represents the aggregate market value of coins or tokens that are currently in circulation. Market cap is commonly used to compare the relative size of different cryptocurrencies.

To calculate market cap, simply multiply the current price of a token by its circulating supply. This gives an estimate of that cryptocurrency’s aggregate market value based on circulating supply.

The concept of market cap is widely used in other markets, such as equities and commodities, as a way to easily compare the size of assets across various sectors.
 

Market cap is calculated by multiplying the current price of a cryptocurrency by its circulating supply. It's worth noting that the circulating supply is not the same as the total supply. For example (hypothetically), if a coin trades at $100 and has 10 million units in circulating supply, its market cap would be $100 × 10,000,000, or $1 billion.

Unlike many stocks, not all cryptocurrency units are necessarily in circulation at a given time. Market cap is typically calculated using circulating supply rather than total supply, because circulating supply reflects the units currently available in the market. Total supply may differ from circulating supply because some tokens may be locked, reserved, or otherwise not currently available in the market.

This calculation can help users compare tokens by relative size and observe how they rank by market cap.

Market capitalisation can help compare a project’s relative size, rather than relying on token price alone. In crypto, market cap is often used alongside price because price alone does not account for how many tokens are in circulation.

For example, one token may have a very large circulating supply and a low unit price, while another may have a much smaller circulating supply and a higher unit price. Comparing market cap helps you avoid drawing conclusions based on price alone.

However, market cap should not be used on its own. A high token price does not necessarily reflect a project’s relative size, because price alone does not capture circulating supply. When you compare two assets by market cap, you’re comparing their aggregate valuation based on price and circulating supply, not investor sentiment or willingness to sell.

In some cases, higher market cap assets may be less volatile than smaller-cap assets, but volatility can still be significant in crypto and may change quickly.

Cryptocurrencies are typically grouped into three categories based on their market cap. Each category may have different characteristics, including differences in liquidity, volatility, and risk profile. Here's a closer look:

Large-Cap Cryptocurrencies
Large-cap cryptocurrencies are often described as assets with market caps above $10 billion (thresholds vary by source). Examples can include Bitcoin, Ethereum, and USDC. These assets may have deeper liquidity and broader market participation than smaller-cap assets, but they can still be volatile.

Mid-Cap Cryptocurrencies
Mid-cap cryptocurrencies are often described as assets with market caps between $1 billion and $10 billion. Examples can include Polygon, Chainlink, and Litecoin. Mid-cap assets may have different risk profiles than large-cap assets, including potentially lower liquidity and less established market depth.

Small-Cap Cryptocurrencies
Small caps are cryptocurrencies with market caps under $1 billion.  Examples include newer projects or niche tokens with smaller communities. Small-cap assets can be highly volatile and may have lower liquidity, which can increase price swings and execution risk.
Understanding where a cryptocurrency falls in this spectrum can provide additional context when comparing crypto assets.
 

When assessing market cap, it's essential to grasp the difference between circulating supply and total supply:

• Circulating supply refers to the number of coins or tokens currently available to the public and tradable in the market.
• Total supply is the total number of coins or tokens that currently exist, including units that may be locked, reserved, or not yet released to the public.
  
   

What does crypto market cap tell you?
Crypto market cap shows the overall market value of a cryptocurrency, which can help you compare relative size across assets. On its own, market cap does not guarantee liquidity, adoption, or lower volatility. It's a helpful metric for ranking cryptos and comparing them across the market.

Is a high market cap good?
A higher market cap can indicate a larger aggregate valuation, but it doesn’t prove utility or guarantee lower risk. Higher market cap assets can sometimes be less volatile than micro-cap assets, but crypto markets can change quickly and volatility remains possible.
 

If you’re comparing crypto assets, understanding market cap is a useful starting point. Whether users are comparing the size of two tokens or reviewing a lower market cap asset, market capitalization can provide additional context beyond token price alone.
Market cap can be one input when assessing a crypto asset, but it should be considered alongside supply metrics, liquidity, and project-specific factors. It should be considered alongside other metrics, such as circulating supply, project fundamentals, and market trends, when comparing crypto assets.
