The transaction fee of $USDC is the cost incurred while using the trading platform. Common types include maker fees (for limit orders) and taker fees (for market orders), as well as withdrawal fees. Maker fees apply to limit orders waiting to be filled and are usually lower; taker fees apply to market orders executed immediately and tend to be higher. Different platforms have different fee standards, and some offer discounts based on user trading volume or holding platform tokens. Withdrawal fees vary by cryptocurrency and network and can be fixed or variable. Understanding the fee structure helps in selecting the appropriate trading method and platform, reducing long-term costs, which is particularly important for high-frequency traders and capital management.
