You have to convert Bitcoin to real and make the withdrawal, it will be discounted by 1.50

In an image it says that the price of my balance
In bitcoin is 439 reais

When I go to confirm, only the value of 405 reais appears

I invested 400 when bitcoin was worth 595 thousand reais

Now worth 670 thousand reais, it seems like I will withdraw the same amount???

I am a beginner on the platform but I am already finding it very lack of transparency
