gold is safer. maybe buy 2/3 gold, 1/3 silver.
i still think that everyone's primary holding should be gold, with silver as a secondary position.
or buy some gold, and buy some other fiat currencies... swiss franc, singapore dollar, yen, yuan, australian dollar, etc.
because if you put your entire bank account into precious metals, you have to accept the fact that they could go down by 30% or 50% relatively quickly. i doubt gold could drop by 50%, but it could happen.... but certainly 30% corrections in gold and 50% corrections in silver are very possible at any time.
so it's up to you... most of my money is in gold and silver, and has been for years, but it doesn't bother me when the price goes down.... but i know that some people freak out when the prices come down.
but especially if you don't need the money for 5+ years... i think that over the next 5+ years, gold and silver should both be much, much higher.... so you should own some if you can. just be sure you understand the risks before jumping in with both feet.
