Markets, moves & the stories behind them

Understanding the Cryptocurrency Market

The cryptocurrency market is a global, 24-hour marketplace where digital assets such as Bitcoin and Ethereum are bought and sold. Unlike traditional stock exchanges, which open and close on a fixed schedule, crypto markets never close — prices update continuously, every day of the year. Analyzing Market tracks live data for the leading cryptocurrencies by market capitalization and presents it in a consistent, easy-to-read format so you can see at a glance how the market is moving. Everything on this site is published for informational and educational purposes only and should not be treated as financial advice.

What is market capitalization?

Market capitalization — usually shortened to "market cap" — is the total value of all coins currently in circulation. It is calculated by multiplying the current price of a coin by its circulating supply. For example, if a coin trades at $10 and there are 100 million coins in circulation, its market cap is $1 billion. Market cap is the most common way to rank cryptocurrencies because it reflects the overall size of an asset far better than price alone. A coin with a low unit price can have a much larger market cap than a coin with a high unit price, simply because it has more coins in circulation.

Circulating supply, total supply and maximum supply

Circulating supply is the number of coins that are publicly available and trading in the market right now. Total supply is the number of coins that exist today minus any that have been verifiably burned (permanently removed). Maximum supply is the hard cap — the largest number of coins that will ever exist, if the protocol defines one. Bitcoin, for instance, has a fixed maximum supply of 21 million coins. Many other assets have no maximum supply at all. Understanding supply helps put market cap into context: two coins can have a similar price but very different valuations depending on how many coins exist.

Trading volume and why it matters

Trading volume measures how much of an asset has changed hands over a given period — most often the past 24 hours. High volume generally indicates strong interest and liquidity, meaning it is easier to buy or sell without dramatically moving the price. Low volume can indicate thin liquidity, where even a modest order can cause large price swings. Comparing volume to market cap can be informative: a high volume-to-market-cap ratio suggests a lot of trading activity relative to the asset's size.

Bitcoin dominance

Bitcoin dominance is the percentage of the total cryptocurrency market capitalization that belongs to Bitcoin. When dominance rises, capital is generally concentrating in Bitcoin relative to other assets; when it falls, money may be flowing into alternative coins ("altcoins"). Dominance is a useful gauge of market sentiment, but it is only one signal among many and should never be read in isolation.

Price changes over different time windows

A single percentage change can be misleading without context. That is why we show price changes across multiple windows — 24 hours, 7 days and 30 days. A coin might be up over the past day but down sharply over the past month, or vice versa. Looking at several time frames together gives a more complete picture of a coin's recent trajectory and helps you avoid reacting to short-term noise.

All-time high and all-time low

The all-time high (ATH) is the highest price an asset has ever reached, and the all-time low (ATL) is the lowest. These reference points help you understand where the current price sits within an asset's full history. A price far below its ATH is not automatically "cheap," and a price near its ATH is not automatically "expensive" — these figures are context, not signals to buy or sell.

The Fear & Greed Index

The Crypto Fear & Greed Index distills market sentiment into a single number from 0 (extreme fear) to 100 (extreme greed). It blends signals such as volatility, market momentum, social media activity and trading volume. Extreme fear can indicate that investors are overly worried, while extreme greed can signal that the market is due for a correction. Like every indicator, it describes sentiment — it does not predict the future.

Volatility and risk

Cryptocurrencies are well known for volatility: prices can rise or fall significantly in a short period. That volatility creates both opportunity and risk. Digital assets are speculative, are not insured like bank deposits, and can lose value rapidly. Never invest money you cannot afford to lose, and consider consulting a licensed financial professional before making investment decisions. Analyzing Market does not provide personalized investment advice.
