#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 like Solana or BSC, where fees are lower. Also, don't forget about trading fees on exchanges — usually 0.1–0.2%, but in large volumes, this becomes significant. Always check the details before confirming the transaction to avoid unexpected costs.
