When there are problems in financial markets and global disasters, most investments lose their value, gold is the exact opposite. High-quality coins and gold bars can be easily transported and stored and are therefore the best medium to take a position value in.
They are small and can be securely locked in homes or in a secret location such as a bank vault. The smart question about gold is that it is a rare substance. Today, there are many websites from where you can easily buy gold bars online.
No matter what happens with global changes in the currency and financial markets, gold will remain valuable. Whether or not the US dollar becomes worthless (which has been a trend for years), gold would still be very valuable.
When you invest in stocks or real estate, you are nowhere near gold. Time is not an important issue. The first question you want to ask yourself is whether you want to own gold or not. If you answered yes to this question, there is no point in delaying your actual purchase.
The real goal is to diversify so that all your assets are not at risk from economic peril and uncertainty. Gold has traditionally proven to be a great long-term investment when compared to other traded investments like stocks, real estate, etc. All the different types of investments may lose their value and become useless overnight.
