Looking for Other Investment Options

I’m really frustrated with the weakening of the dollar.  This is the main currency for my salary.  It started great in the beginning of the year but now, as we reach the end of the year the value keeps on going down.  They say it’s because of the current currency war that China has started.  I really can’t understand most of the issue but what I know is I am really affected.

Because of this, I am looking for other investment options. I heard investing in precious metals such as gold coins and silver coins is a good option. These precious metals have been rising in value over the years. If I invest my hard earned money on these I will have more chance of beating inflation.
