BullionVault has issued this statement:
I know nothing about BullionVault other than that it is an online gold and silver dealer with reported international storage facilities.
I have stated to people in the past that from my perspective it makes no sense to hold gold and silver with online outfits. It just adds an additional level of risk and you may not be able to get your coins during a crisis.
You are much better off keeping physical gold and silver in your possession.
If you want to trade gold and silver, a completely different game, use ETFs and futures.
