#CryptoFees101 Crypto fees are charges users pay to process and validate transactions on a blockchain network. These fees vary by network, transaction type, and network congestion. On Bitcoin and Ethereum, fees go to miners or validators and are usually higher when the network is busy. Fees incentivize participants to maintain the blockchain’s security and functionality. In decentralized finance (DeFi), trading, swapping, or lending may also involve gas fees. Centralized exchanges charge trading fees, withdrawal fees, and sometimes deposit fees. Some blockchains like Solana or Polygon offer very low fees, making them popular for small transactions. Understanding and managing fees is essential for efficient crypto use.
