According to CoinMeta, as reported by CryptoNews, market makers play a crucial role in each transaction, earning profits by providing liquidity. Market makers profit from the difference between the buying and selling prices (i.e., the spread) and maintain active orders across multiple exchanges simultaneously. The presence of market makers makes the order books of exchanges appear more substantial, reducing the risk of slippage. Major market makers such as Wintermute and Jump Crypto hold an important position in the market, providing liquidity and participating in transactions of various pairs. The profit models of market makers include spread capture, fee income, and directional trading profits. Understanding the operating mechanisms of market makers helps investors make more informed trading decisions.
