It's just that our currency is in decline. As the gossips say, it's the "Faz o L" effect.

Can someone explain to me why I have this trade result in my account if I put the money in the currency and never made any trade? My money doesn't yield anything, it just decreases. I put a certain amount in Mercado Bitcoin and there it doesn't decrease, it may not even yield as much, but it always stays above what I put in. Here my money melts and doesn't return, it returns, but it melts again. Help me with this.
