#CryptoFees101 **CryptoFees101: Basics of Fees in Cryptocurrencies**

Fees in cryptocurrency networks are payments for processing transactions that incentivize miners or validators to maintain the blockchain's operation. The fee amount depends on the type of network, congestion, processing speed, and transaction amount. For example, in Bitcoin, fees are determined by the transaction size in bytes and the current competition in the mempool. In Ethereum, fees (gas) depend on the complexity of smart contracts and the market price of gas. Users can choose the transaction priority by increasing the fee to speed it up. Some networks, like Solana, offer low fixed fees. Understanding the fee structure helps optimize costs when transferring, trading, or interacting with DeFi protocols. Always check current fees before sending a transaction.
