G&S or a Better Currency?

I've been reading up a lot on this global financial crisis and the general consensus is to keep stacking physical gold and silver so you can maintain your purchasing power. Some people think they will get extremely rich by investing in these 2 precious metals. But I can only see everyone else getting poor and gold and silver investors maintaining their wealth. I recently purchased a bunch of silver and only a little gold based on advice from a few trusted friends. The more I read about it, I'm not sure why I bought any silver. I am told silver is meant to follow gold but it doesn't seem like it. I'm starting to feel gold is a much safer investment. Anyway, I keep hearing that paper money is not wealth. This is most definitely true when it comes to American dollars but my money is in Canadian dollars. Research shows me that the safest currencies are those tied to commodities, such as the Canadian dollar (CAD) and Canada is not reckless with their currencies and national resources. So is there any point in investing in gold and silver if I am not an American? Any insight would be greatly appreciated.
