Most people who currently knew Bitcoin were the ones stumbled it somewhere because it's getting pump up that's why there's a lot of hype everywhere and that includes scammers creating ads on their fake website. So anyway, I think some people in my area knew already about the Bitcoin but doesn't really care much while the rest are excited about their investment to grow. There are also some who was misinformed or didn't know the whole truth about how Bitcoin works because they were scammed one time in the past but didn't bother to do some research that's why they believe that it's still part of the scam tactics whenever they hear about Bitcoin.
