Here in Brazil, the basic salary is around 800 BRL

In EUA is around 1200 USD, converting it is 3800 BRL.

Your 15 dollars is waaaaaay more accessible for US citizens than us who was paying 31 BRL before the adjustments.

We have a higher ping and a lot of less support.

So yes, I think it's fair for us to pay 31 BRL.
