Sell your copper and Alu now! Or hold it for a while.

I am definitely holding onto my Cu, Al, and brass. I just picked up 20 5-gallon buckets from my former high school, so I now have storage space. As for steel, I am selling it as I fill up my space for it. For now though, I do agree with greytruck here. I'ts like the stock market. You don't make money until you trade-in, and when prices drop its like the commodities going on sale! Buy now while prices are low, and sell when they go back up.
