Live Coin Watch prices update every few seconds. Rank is determined by the market capitalization of a cryptocurrency, which is calculated by multiplying its volume weighted average price by its circulating supply. A coin/token must be trading on 2 exchanges and 3 markets to be ranked. Prices are pulled directly from exchanges.
