#CryptoFees101 Crypto fees vary widely depending on the blockchain, transaction type, and network congestion. Bitcoin and Ethereum often have higher fees due to demand and Proof-of-Work consensus, with Ethereum's gas fees fluctuating during peak usage. Layer 2 solutions like Arbitrum, Optimism, and Lightning Network offer cheaper alternatives. Centralized exchanges (CEXs) like Binance and Coinbase charge trading fees, withdrawal fees, and sometimes network fees. Decentralized exchanges (DEXs) like Uniswap charge liquidity provider and protocol fees. Some blockchains, like Solana and Avalanche, offer near-zero fees, ideal for microtransactions. Users often balance speed, security, and cost when choosing platforms for transfers, trading, or DeFi use.
