Liquidity providers are entities or individuals that facilitate trading in financial markets by offering to buy and sell assets. They help ensure that there is enough volume in the market, making it easier for traders to execute their orders without causing significant price changes. This is especially important in markets like cryptocurrency and stocks, where rapid buying and selling can occur. These providers typically earn a profit from the difference between the buying price (bid) and the selling price (ask), known as the spread. By maintaining liquidity, they contribute to market efficiency, allowing for smoother transactions and better price discovery for all participants.
