Crypto fees are the costs you pay to trade, send, or store digital assets. Think of them as a toll for using the blockchain highway! Every transaction, like buying BTC/USD or transferring ETH, involves a fee—usually paid in the network’s native coin (e.g., ETH for Ethereum). Fees vary based on network congestion; busy times mean higher costs. Exchanges also charge trading fees, often a percentage (0.1%-0.5%) per trade, depending on the platform and your volume. Wallets might add small withdrawal fees. To save, use low-fee networks like Binance Smart Chain or time your trades during off-peak hours. Always check fee schedules before trading—surprises can eat your profits! Learning to navigate fees is key to mastering crypto.
