Investing dollars for a future trip (12-24 months): currency fund, ETF, Wise or stablecoin — what earns and what just gets in the way
You are not investing: you are reserving foreign exchange 12 to 24 months in advance. The rules change. The bank's currency fund eats 22.5% in come-cotas, the ETF has BDR spread, Wise earns nothing, and the stablecoin can be the best or worst depending on where you keep it. Here is the real math, with no financial-influencer fluff.

Airport exchange vs city center vs bank: who charges less (real test in 5 cities, May/26)
We took USD 500 and simulated the same exchange at three points in each city — airport, downtown exchange house, and bank — in São Paulo, Rio, Lisbon, Madrid, and New York. The maximum difference exceeds R$ 280 in a single operation. And it isn't always the airport that's the villain.

Where to buy US dollars cheapest in Brazil before traveling (2026)
Brazilians leave home thinking the airport exchange booth "only takes a little" and the bank "is safe." It's exactly the opposite. In May/26, buying USD 5,000 at Confidence on Paulista costs R$ 27,450. At the Guarulhos airport booth, R$ 30,150. At Banco do Brasil, R$ 29,300. At Wise, R$ 27,080. The gap between worst and best is a full international hotel night — on a single purchase.
