Revolut is an app with a pre-paid debit card for paying in foreign currencies.
You have one account with Revolut and three "wallets" within that account - one in USD, EUR, GBP. You can download statements by currency. That means I know the highest balance in the USD wallet, the highest balance in the EUR wallet, and the highest balance in the GBP wallet.
For FBAR purposes. Can I convert each of the highest values to USD, add them together and report that amount?
Doing it that way will result in an amount which is higher than the actual highest balance, because the highest balances in each wallet didn't fall on the same day. It would be much, much, much easier though than having to figure out which day the sum of all 3 wallets was the highest.
Would be grateful for any input,
