By default, Coinosh displays the balance and transaction amounts in USD as the base currency. However, users have the option to change the base currency to another fiat currency of their choice within the wallet settings.
The exchange rates for converting cryptocurrencies to fiat currencies such as USD or EUR are provided by a trusted third-party service called coingecko.com. It's important to note that while Coinosh works with reliable data providers, the wallet cannot guarantee that the displayed exchange rates are always real-time and accurate. Therefore, users should exercise caution, especially when transacting with large sums of money.
