These days someone posted that in conversion you pay 0.1 and in trade you pay 0.01. Theoretically, converting 10 or 100 should be the same, but I also don't think it is.

Guys, I never understood Binance's fees. If I convert, for example, 10 times the value of R$10.00 in different cryptos in one day, will I be charged more fees than if I convert R$100.00 to just one crypto? Or is there no fee for adding cryptos to the portfolio? And when I want to take cryptos out of the portfolio, converting them to reais to send to my bank, if I take them out little by little, will there be more fees than if I take them out all at once? Thank you.
