#CryptoFees101 is an educational tag used to explain the different types of fees users encounter when transacting with cryptocurrencies. Common crypto fees include network (gas) fees, which pay miners or validators to process transactions, and exchange fees, charged by platforms like Binance or Coinbase for trading or withdrawing funds. Fees vary by blockchain—Ethereum gas fees can be high, while others like Solana offer cheaper transactions. Understanding fees helps users avoid overpaying and manage costs efficiently. The hashtag often appears in beginner guides, forums, or social media posts aimed at helping newcomers navigate the complex world of crypto transactions.
