It's really about misinformation with regard to people who are doubtful of bitcoin's capability. Or probably those people who were scammed with HYIPs with their bitcoin, and probably got traumatized by it. There are many reasons why someone would be apprehensive about something, so we must be ready to answer those questions in such way that won't put bitcoin in a bad light. And also, be realistic and don't try to hide the flaws just to encourage them. Give them disclaimers and warnings that bitcoin isn't perfect and has its own weaknesses, much like our local fiat currencies.
