Something I didn't understand when I started was why I was losing small amounts when making trades. Then I learned that there are 'fees' or commissions that are charged for each transaction. On Binance, these commissions can vary depending on the type of operation and the level you have. I saw that if you pay with BNB you can get a discount on the commissions, which seems useful if you make a lot of transactions. Since I have little capital, I try to make few trades to avoid losing too much on commissions. Do you use BNB to pay less in fees? Any other tips to save?
