Never convert your currency unless it is less than $5. Trade instead, the fee is much lower.

I started in the world of cryptocurrencies a few days ago, but I can't understand the conversion rates.

The amount I have in the currency is R$$ 245.75 reais, but when I try to convert it to BRL, it says I have R$$ 232.27

So just to convert the crypto to local currency, I'm being charged more than R$20.

And the more I have, the greater the discount on the conversion.

I saw that it's charged both to buy the currency and to sell it.

I thought the fee was only charged if I was making a withdrawal.

Is it worth doing day trading this way?

Is that right?
