Market makers are firms or individuals that provide liquidity to the market by buying and selling cryptocurrencies to traders, investors and market participants around the world. They buy cryptocurrencies from sellers who are looking to part with them and sell them to buyers who are looking to acquire them. In this way, they help to facilitate trade and ensure that there is always someone on the other side of a trade. Market makers are important because they help to reduce the volatility of prices and provide a source of liquidity to the market.
