🐋 Beyond watching price charts, you should also understand these basics: market cap and trading volume
Circulating market cap is generally the current price multiplied by the circulating supply, and is one of the most common figures used to measure a coin's size.
Market cap is a figure derived by multiplying the price by the circulating supply; it does not represent actual money flowing in. When trading is quiet, even a small amount of capital can significantly move the market cap.
