The FBAR report calculates your highest FIAT value for each Exchange during the selected calendar year. Use those values to file your FBAR report.
Who Must File FBAR?
A US citizen that has a financial interest in or signature authority over foreign financial accounts must file an FBAR, if the aggregate value of the foreign financial accounts exceeds $10,000 at any time during the calendar year. More details on the IRS website
Please make sure that all your transactions, especially deposits and withdrawals of FIAT currencies, are listed in your CoinTracking account.
