Outside image of bitcoin is neither positive nor negative. It's still on the gray zone, lots of people don't have strict decissions about bitcoin. They still try to understand and see the details of it. For me, it's very positively and I trust it myself.
I would still call it negative. Even my roommate who is finishing his bachelors, and reads a lot of wall street blogs calls bitcoin a scam and ponzi scheme (lol)
We can't blame them if they don't believe in bitcoin, it doesn't matter whether they believe it or not, what matters is we are earning money through it and it is not our fault if they are narrow minded on this thing. Maybe they just have another way or they are just having hard time to believe that bitcoin could be a source of income.
