#CryptoFees101 Crypto fees are payments required to process transactions or execute smart contracts on blockchain networks. These fees vary by network—**Ethereum** uses gas fees (paid in ETH), which spike during congestion, while **Bitcoin** charges based on transaction size and demand. Layer 2 solutions (e.g., Arbitrum, Lightning Network) reduce costs by processing off-chain. Exchanges also charge trading fees (maker/taker models). **DeFi platforms** add gas + protocol fees for swaps, loans, or staking. Always check fees before transacting—some chains (Solana, BSC) offer lower costs than Ethereum. Smart fee management = more efficient crypto investing!
