When problems happen in financial markets, and disasters occur globally, most money investments drop in value, gold does the precise opposite. High-value coins and gold bars can be easily transported and stored making them the best medium to take a position value in. They are little in size and will be safely locked up in your house, or a secret location like a bank vault.
No matter what happens with global changes in currency markets and finances, gold will continually be valuable. Whether or not the US dollar becomes worthless (which it has been trending towards for years), gold will still be highly valuable. One can also visit this link to buy gold bars online.
You cannot approach gold the means you approach stock or real estate investments. Timing is not an important issue. The initial question you would like to ask yourself is whether or not or not you think you wish to possess gold. Once you answer that question in the affirmative, there's no point in delaying your actual purchase.
The real goal is to diversify so that your overall wealth isn't compromised by economic dangers and uncertainties. In comparison with other investments which will be traded like stocks, property, etc, gold has proven itself traditionally to be a great long-run investment. All different varieties of investment will lose their whole value and become worthless overnight.
