In my opinion, anybody who thinks 'Satoshi' didn't create Bitcoin with the intention (at least, in part) of getting rich, I think you're fooling yourself. It's clearly built into the structure.
Yet we haven't witnessed an intense development effort for such novel systems before or since Bitcoin. There were many different plans for a distributed currency (e.g. a distributed anonymous version of ripple), but only by a handful of people. In my experience, you just can't and don't work on such stuff if you intend to get rich. He must have imagined gaining wealth as a consequence of his success, but the reason the structure is built this way is definitely about success of the currency. As a consequence, people who believed in it got to have more coins. Even so, there are many early adopters who (at least claim to) have very little coins left.
This is probably closer to reality:
I bet even he can't believe this shit actually worked though.
What surprised me about molecular's analysis though is the amount of coins that were never moved. I wonder if that is the usual trend, or it shows a different behavioral pattern for first comers. Has anybody made a "the number of coins that haven't moved since" graph?
