Has anyone else been stacking copper? I stacked silver up until it went over $30 an oz, and now while copper seems to be kicking butt, I bought 4000 oz's (rounds and bars at between $2 and $2.5 an ounce) and I am wondering if this is a smart move. I mean raw copper is at around $6 a pound, I bought @ 6 times the current price for refined, so am I doing the right thing? Thnx
