Bitcoin Litecoin & Gold (Should I trade my Silver for Gold?)

After listening to another awesome youtube interview with Andy Hoffman and Adam the BitMeister I was stunned that I was so close to what Andy is holding long term. Andy basically said BTC LTC & Gold were his long term holdings. I have BTC LTC and silver.

Here is my question. Should I sell my silver and move into gold? Or should I hold my silver and purchase gold from here on out?

What do you guys think?

And Thanks to Adam and Andy for getting me to thinking this way!
