#CryptoFees101 Crypto fees are small charges paid to process transactions on a blockchain. They reward miners (Proof of Work) or validators (Proof of Stake) who maintain the network. Fees vary by blockchain: Bitcoin and Ethereum often have higher fees, while networks like Solana or Polygon offer lower costs. Fees fluctuate with network demand—higher congestion means higher fees. Understanding fees is crucial: they impact the cost and speed of your transactions. Tools like gas trackers help users choose optimal times to transact. Always check fees before sending crypto to avoid surprises and maximize value.
