#CryptoFees101 Crypto fees impact trading profitability. They vary by blockchain and platform. Ethereum’s gas fees can hit $10-$50 during congestion, while Solana’s are under $0.01. Exchanges charge trading fees, e.g., 0.1% per trade on Binance. High fees erode profits, especially for small trades. I once paid $20 on an ETH transfer, eating 10% of my funds. Use low-fee chains like Polygon for small transactions and trade during low network demand. Always check fee structures before transacting!
