How to Choose Without Making a Mistake
Making the right choice depends on a few objective criteria. First, check whether the money can be withdrawn quickly. Next, assess the product’s risk and determine whether it makes sense for a reserve that cannot withstand major fluctuations.

- Net return: Compare what's left after fees and taxes.

A simple example illustrates the problem: if your reserve is 10,000 R$ and you lose 700 R$ in a volatile investment, you’ll already start running short on coverage for unforeseen events. When it comes to reserves, preservation comes before growth.
