All trades are settled in US Dollars (USD), regardless of the region where your assets are stored. Similarly withdrawals are always denominated in USD, though your bank may convert them to your local currency upon receipt. Please always check with your bank about receiving USD deposits and any fees or restrictions prior to setting up for a check or wire withdrawal.
If you prefer to settle in a different currency, you have the option to take delivery of your gold and sell it at a local dealer.
