Remember: don't keep changing currencies, this reduces your profit. And don't panic when they fall. In a few days they will rise again. This is normal if the currency is consistent and yours are.

I'm new here investing a capital of 300 reais, did I do it right? And I wanted to know which ones you would recommend to me, I'm going to make an average of 300 reais per month to be able to invest, should I continue? Or should I buy others?
