Newb from Brazil!

Hello mates, it’s nice to join the forum.

I’m from Brazil and just started on Crypto Market.
Thanks to all who have contributed in this forum, I read a plenty of posts here which helped me a lot so far.

I don’t know if it is the right place to ask, but here we go:

For brazilian users, as far as I know, Rippex is the only wallet available for deposits in BRL (brazilian reais). The problem is that in Rippex I can’t see a good level of liquidity as in Poloniex/Bitstamp (I understand that Poloniex and Bitstamp are Exchanges).
Considering a brazilian investor, who has BRL to invest and Rippex as its initial wallet, what should be (if it exists) the steps to reach Exchanges like Poliniex/Bitstamp?
