That depends on the casino. Some casinos accept dozens of currencies, while some work with basic currencies only: USD, CAD, AUD, GBP, and EUR. However, even if the casino doesn’t support your local currency, you still can make a deposit as long as your payment provider can exchange your initial currency to the currency accepted by the casino. For example, you can exchange Brazilian real for Canadian dollars, but you will have to pay an exchange fee charged by your payment provider.
