When trading crypto, fees can significantly impact your profits. These fees come in several forms: trading fees (usually a percentage of your transaction), withdrawal fees, and network or gas fees. Different exchanges have different fee structures, often offering discounts for using their native tokens or high trading volumes. On decentralized exchanges, gas fees can be high, especially on congested blockchains like Ethereum. Some traders overlook these costs, but smart traders always calculate fees before entering or exiting a position. Choosing low-fee exchanges and being strategic about the timing and type of transactions can help you save a lot over time.
