There is never a bad time to buy gold. Ever. Worst case scenario is you buy "too late" to see huge dividends and you'd "only" have the value at the time of purchase/market value. So....no downfall.

Gold will never be worthless, it's incredibly malleably and is rust proof. It's also gorgeous and there's something within the human psyche that admires its intrinsic beauty.

Silver is the worlds best conductor and also will always carry value because of it.

If you want my opinion (i am not a financial advisor), it is to watch the difference between physical and the GLD etf. when you start to see the gap grow too much it means that you are paying more of a premium for taking delivery of physical. the only reason this gap wouldn't go back down at a later date would be the collapse of the usd or the financial markets. That isn't a 0% likelyhood, so you have to make the decisions, but in times of strife it is usually better to buy the etf, and then when things calm down you can convert to physical.

Also, see if you can find a local coin dealer. news like this means that some people will be reminded of what they have and cash out.
