Market Maker
A market maker is an entity or algorithm that provides liquidity to the market by maintaining a constant presence of buy and sell limit orders. By quoting both sides of the market, they facilitate trade execution for other participants, earning the bid-ask spread as compensation.
Market makers play a vital role in reducing transaction costs and narrowing spreads, which improves overall market efficiency. They must manage significant inventory risks, as they are obligated to take the opposite side of trades during periods of market stress.
In cryptocurrency, market making is often highly automated, with sophisticated algorithms adjusting quotes in real-time based on volatility and order flow. Their presence is a cornerstone of market microstructure, ensuring that assets can be traded with minimal friction even when retail interest is low.
