Sure, this is a reasonable assessment. Only a teeny-tiny portion of a world population even heard about it. Those that heard something, probably paid it no attention, like a background noise. Those that paid it some attention, probably got it wrong due to horrible media coverage, lack of education or personal biases. Those that got it right, most don't believe it has a chance to survive or become a serious force.
So, BTC holders are still a very tiny minority of a tiny minority, and declaring it "mainstream" is beyond ridiculous. Our favorite coin has a loooong way to go still...
