Fees make a huge difference in a trader's profitability. That's why I calculate all entries and exits considering about 2% total fee (buy + sell). This helps me know exactly the minimum amount I need to reach to make a real profit. In exchanges like Binance, the standard fees are 0.1%, but they increase if you use market orders or tokens with low liquidity. Whenever possible, I use limit orders and pay attention to the order book to avoid slippage. Every cent saved counts.
