I wish I hadn't been so busy at the time to pay attention. I was in the middle of working full time, trying to finish school, and moving to another state when that stuff was all new. If it had been 10 years earlier when I was a young bored computer nerd I'd probably have millions worth of the stuff.

I'm with you though, they are buoyed a lot by the weakness of other investments. I'm only in stock markets inside retirement accounts anymore, a lot of which I don't have a ton of choices in anyway. Although, I've been on a bit more of a spending spree than holding onto cash. Lot of not very liquid investment stuff like real estate and the like. Even some odd things like "self-investment" meaning I've been doing trade school. For no reason other than to learn.
