#CryptoFees101 is a basic guide to understanding the fees in cryptocurrency transactions. Every time you send crypto, you pay a fee for the network to process your transaction. These fees vary depending on the blockchain: in Bitcoin and Ethereum, they are paid to miners or validators; in others, like Solana or Polygon, they are lower. Fees can increase when the network is congested. There are terms like gas fees in Ethereum, which determine how much it costs to execute operations. Understanding these fees is crucial to optimizing costs and avoiding overpaying in simple or frequent transactions.
