If it's 1 person we're talking about, and that person was in possession of something like 500.000 - 1.000.000 Bitcoins from what I've gathered, one would wonder why he/she hasn't cashed out any of it yet. I mean, it's a stupendous amount of money. The coins might be lost forever, the creator might have the integrity to leave them untouched, or the person is no longer with us.

The creator was obviously intelligent, and maybe he/she knew from the beginning that any commodity can artificially create additional value as long as there's a certain mystique associated with it. It's basically a myth now, and an interesting one that gathers the attention that Bitcoin might need to pull off what it was meant to do.
