At first they don't. Personally, it took me a while to get into Bitcoin. I thought it was a scam online so I never really tried to learn what this is. Only when a friend of mine introduced it to me as a form of passive income that I just have to hold onto did I get interested. People will have different styles of introducing Bitcoin and people will also have different intakes on the explanation. If you can't explain it in a way of how you want to portrait it then it will be difficult. Find a common ground and start from there.
