Understanding crypto fees is crucial for anyone stepping into the world of digital assets. Whether you're trading $BTC, swapping tokens on DeFi platforms, or just transferring coins between wallets, fees can quickly eat into your gains if you're not careful. Network congestion, blockchain type, and platform policy all affect how much you pay. For example, Ethereum gas fees can spike drastically during high activity. Learning how to optimize fees—by choosing the right time, using Layer 2 solutions, or trading on fee-friendly exchanges—can save you a lot. Always read the fee breakdown before confirming any transaction. Knowledge is power.
