... This week in Stolfi's utopia.
In the grand experiment of Bitcoin, one involving a large number of human participants and for a variety of reasons... expecting only the right people being involved for the right reasons is ridiculous.
A tool has been created. What the tool enables, where that leads, and how, is up for history to decide. I doubt Satoshi was ignorant of this fact when he released it into the wild.
What attracted the scammers and snake oil peddlers was the money. The big ones came in early 2013, it seems, although Hal Finney is said to have predicted that twist already in 2009. IIRC, Satoshi reacted has if he had not given it much thought.
Satoshi's basic mistake was to make the currency non-inflationary. It is forgivable, since he was a computer type and not an economist. I would have made the same mistake. Inflation is bad, of course -- everybody knows that, right?
Satoshi's disappeared six months after Jed McCaleb repurposed MtGOX to be a bitcoin exchange, and 3-4 months before it was sold to Mark. Maybe Satoshi saw the future when MtGOX started to attract speculators.
