#CryptoFees101 are a fundamental part of how blockchains operate. Every time you send, swap, or stake, you’re paying a fee that helps secure the network and reward validators or miners. On Bitcoin and Ethereum, these are called network fees or gas fees, which can vary based on demand. Centralized exchanges like Binance or Coinbase also charge trading fees, typically a small percentage of the transaction. Some DeFi platforms might include liquidity provider fees or protocol fees as well. Understanding these helps you make smart trades, avoid surprises, and even pick the right time to act. Pro tip: use Layer 2 networks or low-fee chains like Solana to save costs. In crypto, every satoshi counts—know your fees, and trade smarter.
