Platinum is a play on chaos for me. I don't really believe it will survive a depression due to its mostly industrial uses.
But it might just work out somehow or may rise up after it's all over, so having a few oz's doesn't hurt.
I stopped buying gold as soon as the POG passed $1600 a few months ago.
I felt it was being pumped up too much and still think it's got too much padding (in terms of GSR).
The likes of JPM and GS ruined it.
Right now silver is a great buy.
When gold loses it's padding, I will put it back on my buy list.
