Liquidity is one of the most important concepts in the world of trading and financial markets, and it refers to how easily an asset can be bought or sold without significantly affecting its price. The more liquidity there is in the market, the greater the ability to execute trades quickly and at fair prices. In the world of cryptocurrencies, liquidity plays a vital role as it ensures price stability and reduces the spreads between buying and selling. Understanding liquidity helps traders and investors make informed decisions and achieve better profits. Therefore, it is essential to know the sources of liquidity and how to measure it to avoid risks and achieve success in trading.
