Gold is definatly the best one to keep in a safe at home, I find wierd though that people buy gold but then dont actually have the gold in their possession and has a piece of paper proving that they do own gold, and the funny thing is that's how banks first started out! Nice thing about gold is that a big bit of money isnt such a big bit of gold so its easy to store :)

What country are you in sunlit? And how is it there with people carrying cash or is it just card there also?
