Circulating supply in cryptocurrency represents the number of coins or tokens available for public use, excluding locked, reserved, or burned tokens.This metric is crucial for understanding market cap, spotting overpriced tokens, and making informed investment decisions.Circulating supply is calculated by subtracting locked tokens and burned coins from the total supply.It helps investors gauge how much of a token is actively trading on the market vs. held elsewhere.Centralized projects often have controlled token distributions, while decentralized projects follow rules set in the code.Factors like mining rewards, token unlocks, and token burns can affect circulating supply.Market capitalization is calculated by multiplying a coin's price by its circulating supply.Understanding supply metrics can prevent surprises like sudden price drops or dilution of value.Checking circulating supply vs. total supply vs. maximum supply helps assess a coin's economy and valuation.Circulating supply data is tracked using blockchain explorers, project disclosures, and analytics platforms like CoinGecko and CoinMarketCap.
