#CryptoFees101 Commissions in crypto can be hidden enemies. During trading, it is important to understand how much you will actually pay to the exchange or network. For example, in the Ethereum network during high load, the transaction fee (gas fee) can reach dozens of dollars! Therefore, many users switch to Layer 2 solutions (Arbitrum, Optimism) or to other networks, such as Solana or BSC, where the fees are lower. Also, don't forget about the trading fees of exchanges — usually 0.1–0.2%, but with large volumes, this is already significant. Always check the details before confirming the transaction to avoid unexpected expenses.
