#CryptoFees101 Crypto fees are costs incurred when conducting transactions on blockchain networks. They vary based on the network's congestion and complexity of the transaction. Fees serve as incentives for miners or validators to process transactions, ensuring network security. Popular blockchains like Ethereum often have higher fees during peak usage due to limited block space, while alternatives like Solana or Polygon offer lower fees. Innovations like Layer 2 solutions (e.g., Optimism, Arbitrum) aim to reduce costs by processing transactions off-chain. Stable fees and scalability remain critical for broader crypto adoption, especially for DeFi, NFTs, and cross-border payments, where affordability matters most.
