I arrived here not knowing much, and I invested in three currencies, one of them being BOB (this one, without studying much about it) just based on the advice of enthusiasts of this currency. And the only advice I can give is: if you are here with limited resources and dream of changing your life, DO NOT BUY BOB. It may reach its peak, but it may not... I have already lost more than R$300.00 here. I didn't sell, I didn't buy more... but I can afford this supposed luxury, but if you can't, don't do it. It's cowardly to encourage others to spend what they don't have!
