It's inevitable that in time copper will become what silver was - yes there's a lot more of it , but the fact of the matter is, as China, India, and Brazil/Russia grow and modernize, the consumption rates will skyrocket of ALL precious metals - dont forget, eacch has an industrial use as well (except maybe gold, ironically)
I'm not saying just blindly buy buy buy at the peaks, but I am acquiring silver on pullbacks and just storing it away. If we get a parabolic move in metals, such as we had in certain internet stocks in the late 90's or real estate in the mid 2000's - Im talking several hundred percent - THEN maybe I will hit the bid, but in truth I don't need the immediate profits and I don't want to miss the gains over time. Buy it, store it, stack it, maybe coo softly at the pile and rub it with a diaper once in a while. Thats it.
