Great article and you make some very valid points. I believe in gold, however, physical silver is a fantastic buy right now and is extremely undervalued. Traditionally, silver gold ratio has been approximately 15:1 and at this time it is trading at around 66:1!! Rather than having smaller gold denominations silver IMHO is a better option, as well as physical fiat currency outside of the bank (under your mattress?) and of course bitcoin. Fiat currency isn't going to die over night and during a crisis you should burn through your currency first.

I have a BBC philosophy to preserve my wealth. Bullion, Bitcoin, Cash in that order of importance.
