A lot of people are spending BTC they bought just recently or acquired through jobs, etc. The early adopter slice is much smaller than you think.
if you dont mind little offtopic: I read 60%+ Bitcoins have never moved. What do you think of that. Are those Bitcoins lost? Sitting somehwhere in a junkyard on 5 years old laptotps? Or are the early adopters completely GREED RESISTANT and they will never cash out? (They surely havent when the price was 1000USD/BTC)
