Good stuff @mikeshuh! I like platinum myself. One thing to keep in mind, platinum and silver are both relatively small markets, in regards to volume traded, versus Gold. Basically both the silver and Platinum prices are much easier to suppress, because they are smaller.

Gold is a much harder market to contain due to volume. When Governments worldwide are buying up record amounts of gold, and Russia and China are trading oil in Gold, instead of the dollar, that market is just too large to manipulate as easily.
My opinion, for what it's worth...Platinum is very good to own long term.
