MarketCap is a metric used to measure the total value of a cryptocurrency in circulation in the financial market. It represents the sum of all tokens or coins of a cryptocurrency multiplied by its current price.

The formula to calculate MarketCap is as follows:

MarketCap = Current Price of the Cryptocurrency × Total Quantity of Tokens or Coins in Circulation.

For example, if a cryptocurrency has a current price of $100 and there are 10 million tokens in circulation, then its MarketCap would be:

MarketCap = $100 × 10,000,000 = $1,000,000,000 (1 billion dollars).

MarketCap is an important metric for evaluating the capitalization and relative size of a cryptocurrency compared to others. It is also used to rank cryptocurrencies based on their popularity and market relevance. Cryptocurrencies with a high MarketCap are often considered more established and secure, while those with a lower MarketCap might be more volatile and risky.
