Is there any minimum account balance that I need to maintain?

Yes, but it’s minimal. Since your monthly account fee (for Plus Account) and any fixed transaction fees are deducted from your multi-currency account, you need to maintain a small cash balance in the account to pay for it. If your account balance falls below the threshold, we will notify you to add funds to the account. If your balance falls to 0, we reserve the right to terminate your account after a 30-day notice.
