Charts, bid and asks live and Ratios
Accessibles charts of historic values of gold at goldmoney.
Being able to see the live bid and ask to have a more accurate idea of the cost of a GAU at the moment.
Maybe have some fun with ratios:
Gold / Dow
Gold / bitcoins
Gold/ average realestate (canada/usa/other irrelevant countries ... (sorry this is my bad sens of humour)
Having these infos would make goldmoney a one stop shop for everything about gold.
