I find that incredibly annoying, especially due to the media - which is a good point. In my country the media also portrays it as some kind of money created out of thin air, only used by criminals and people who want to buy drugs. No one really explains what is really going on and if they explain it, the explanation is so shitty I want to call them and explain to them that they are just plain wrong. How do you deal with that? I know you can just ignore it...
For me convincing people about bitcoin its not hard, because all we need is how we introduced to them, and how they get more profit from bitcoin. And also its not hard or very very expensive when you go for trading.
