Though it isn't as flashy as gold, silver and oil, copper ranks up high on the commodity list.Its price is often a very reliable indication of the health of the global economy, considering how much of the world's infrastructure – transportation, telecommunications, construction, etc. – rely on copper.Still, copper can be just as profitable…
It might not be as liquid as gold. Then again, not everyone has the kind of cash ready to start buying ounces of gold, or even quarter or tenth ounces of gold. Ounce of copper isn't that hard to buy though, if you find a good source.
I do think that copper is very profitable. Look around and you see it all over and we need it to build so many things. I think it is very valuable not just money wise.
I think investing in copper is as simple as extracting it from previously used but no longer needed items like old copper pipes, old wires, cables, etc... No longer need a cable? Take the wire out of it and stash it. The way prices seem to be going, it couldn't hurt to try it.
