Um cambista, ou pessoa que realiza operações de câmbio, pode ganhar dinheiro de diferentes formas. Essas pessoas geralmente trabalham em 🗝 bancos ou outras instituições financeiras, where they help clients convert currencies. They buy currencies at one exchange rate and sell 🗝 them at a higher rate, making a profit from the difference. Some currency traders also speculate on future currency movements, 🗝 buying and selling currencies based on their predictions of exchange rate fluctuations. However, this type of trading is risky and 🗝 requires a deep understanding of the financial markets.

Outside of traditional financial institutions, some people also work as independent cambistas, often 🗝 called "black market" or "street" changers. These individuals usually operate in countries with strict currency exchange controls, where there is 🗝 a significant difference between the official and black market exchange rates. They buy currencies from travelers or businesses at a 🗝 lower rate and sell them at a higher rate, making a profit from the spread. However, this type of activity 🗝 is often illegal and can result in severe penalties.
