I agree with the assessment of copper prices rising, as all commodities will be going into an inflation cycle. Remember the days where copper was over $4, and thieves were electrocuting themselves stealing live circuits just to steal copper. But copper is heavy, just as silver is also bulky to keep in any volume. The cost of everything will be based on the cost of energy needed to extract the commodity. Such as the about to energy required to solve bitcoin equations to get a digital commodity. Good post.
