Good, hoarding masked as an investment strategy is rarely that rewarding (both financially and IRL). There's only so many people you can brag to about your collection of unusable boxes.

I know a guy in Belgium that makes a very nice living of his collection of unusable boxes. And a couple here in NL as well.

I have a friend who most certainly is not but thinks he is going to be. Every market lives and dies on the bigger sucker existing.
