Start with the mid-market print
BTC to BRL and USDT to BRL pages give a global mid-market size check. Brazilian on-ramps and P2P ads can sit off that index depending on PIX rails and demand.
Use the converter to size, then measure any advert gap with the P2P premium tool.
What local settlement still decides
Banking methods, compliance checks, and venue liquidity decide what you actually receive. Mid-market is not a locked PIX credit.
Read mid-market vs exchange rate so you do not confuse an index with a fill.
Suggested path
Open the pair that matches your fiat, enter the amount, skim the chart, then confirm the desk or advert you will use.
