If all you're doing is trying to preserve wealth it's hard not to be good since it's current price is probably more rock bottom than any metal out there, so you can likely hold and easily make money too.  But in the future, gold and silver will likely have a higher price gap premium between sticker price and cost of production.  It's 100% inevitable gold will spike at least twice it's current price in current dollar purchasing power when you compare things like debt levels vs gold ratios seen in the past.  When that happens, silver will go to at least a 30:1 ratio of around $75-85.  Will platinum match those type of 4-4.5x returns in current purchasing power?  I don't know.

This is all in terms of a regular metals bull market and not a currency collapse or anything.  It's hard to go wrong with gold, silver, or platinum at this point, but I think silver will have the highest returns if you can wait for the inevitable metals bull run to occur.  The idea a few propagandists have put out that the govt can revalue gold to $10-20k while simultaneously suppressing silver to make it not go up at all is complete nonsense.  At the time when governments around the world revalue gold, there will probably not be an ounce of gold or silver on any store shelf left to buy, so the free market would push things up to the moon no matter what.
