In the world of cryptocurrencies, fees are something that many newcomers learn about too late. When sending tokens or interacting with DeFi protocols, users often find that the amount they actually receive or spend differs significantly from what they expected. This is all due to crypto fees, which can vary greatly depending on the network, blockchain congestion, and the wallet used.

For example, in the Ethereum network, fees can sometimes reach tens of dollars, especially during periods of high activity. Meanwhile, networks like Solana or Polygon offer significantly cheaper transactions — sometimes even less than one cent. It is important to understand how gas fees work, what slippage is, and how to avoid unnecessary expenses.

Understanding the structure of crypto fees helps to save funds, especially when conducting frequent transactions or dealing with large amounts.
