Like I've said before, and some of you already get it, I'm buying physical PM's along with useful goods and learning practical skills, as an insurance policy... all of this could turn out to be a positive investment at some point in my life, or it could turn out to be a bad one, but either way, I have at least some form of "wealth security" beyond the dollars in my bank... that's all it is.
If you bought an ounce of silver for $25 this week, would you miss the $25? Would your budget suffer? If so, don't buy it... if you wouldn't miss it and still eat well, and would spend that $25 on something else with zero tangible value, then I would ask "why not?".
