Platinum

Can't believe no one has yet made a topic on this.

So, what do people think of this one as opposed to silver and gold? I believe last year at one point it was almost $400 over gold, and now it's sort of floated around $1750-$1850 for almost a year. It sure seems to be vulnerable to wild price swings in a way gold and silver are not - I've seen days where gold is down $2.00 and silver down $.25 with platinum down $20-$30. I have a single one ounce platinum coin but I'm not too sure whether I should be investing in more or not given the price volatility and how prices seem to be "stuck" in the aforementioned price range.
