We tend to fear on few things. Some are scared because it's not mainstream, if they run into issues, they can't just make a report and say that their wallet has been stolen. I'm hoping for this to change and that more people will adapt to bitcoin next year. Adaptation has already began. Lets hope to see more.
We can't blame them, all they heard about internet when it comes to money is "it is a scam" so probably that's how they look at bitcoin, there is no way we can change that... Besides, anything new or alien to their knowledge will always be a threat or a danger. That is one that stops other people from using bitcoin, they have no knowledge about it.
