IMO, by standard definitions, anyone who is "in" before Bitcoin has nibbled itself a solid 2% of any given market is an early adopter.
That's the thing, I don't think a lot of Bitcoin users really realise just how much of an early adopter they are, barely anyone knows about about Bitcoin nevermind has a real understanding of economics, that said, it is fairly amusing seeing people accuse me of having a hoard of Bitcoin stashed away and being incredibly rich when I hardly have anything right now. That said, that could all easily change this year because things are going to be epic.
This implies that people that own Bitcoin have a real understanding of economics, with all that "double by December 2015" talk last summer...
