I think the point here is:
The world now knows about bitcoin, pretty much all of it.
But it knows it for what it is: A trading game with scummy figures playing captain of the industry and an attached army of zealots with the attitude of MLM participants.
In short: We're out of suckers.
I agree that we're "out of suckers" as it were but I disagree that the whole world knows about Bitcoin.
Outside of my fellow news/tech junkies, only a couple people I know have heard of it. Then of course there's also the fact that the majority of the world doesn't have Internet access (
source).
For our purposes that's everybody. When the bubble popped my dad told me on the phone he did read about "those bitcoins" and "how huge they have become" in the newspaper.
On that day I saw two teenagers on the street following the bitcoin price on their androids. ("216 Euro!!!")
They all learned what Bitcoin is all about: Buy and sell bitcoins.
