Market liquidity is a critical concept in finance and trading, representing how easily assets can be exchanged for cash or a cash equivalent. High liquidity indicates that an asset can be bought or sold quickly at stable prices, while low liquidity can lead to larger price swings and higher trading costs. Liquidity is influenced by various factors, including market participants, trading volume, and the overall market environment. In the context of cryptocurrencies, liquidity is particularly important due to the often volatile nature of crypto markets, and it is commonly assessed through metrics such as trading volume and bid-ask spread.
