Hold a multi currency account with your bank, keep any cash asset as liquid as possible, the gold myth is last century, history already tells us the gold price should be 30 to 40 percent higher than current but it isn't, it was devalued because of the myth and as people started to look to it as an option, even the best market analyst's will tell you they don't have a clue where we are or where we are going.
I would never recommend anyone keep large amounts of cash in the bank. The government makes all the rules and can change them at any moment.
All fiat currencies eventually return to their true value... zero. As long as the confidence is maintained, fiat paper has value, but when the confidence is shaken/lost... zero value (i.e. Weinmar Germany, Zimbabwe, Argentina, etc...).
Central banks HATE gold and silver. It is a competitor against their fiat paper. TPTB have manipulated the gold and silver prices (to keep them low) for a very long time. That will end someday... soon.
The spot price of gold and silver may fluctuate, but they always will have value.
