Don't you think that if Bitcoin wouldn't have a future you and I wouldn't stay here talking about? People made bitcoin, people will give him a future.
Bitcoin is from people, for people, that's right. But it's normal that some people have their doubts. In my personal life there are non Bitcoiners that do like the concept, but are afraid of the fact that no one is in control of Bitcoin. They don't understand how it has value since no one is in charge, etc. I think it's better from them to express their concerns so we can inform them about how Bitcoin works, instead of these people spreading false information due to their ignorance.
You are right that people are afraid and don't want to learn about bitcoins, but those who know will never leave bitcoins and that's the plus factor for us, because now the users can only increase and never decrease. At least those who love bitcoins will tell this to next generation, their children and brothers and all. So the community won't die ever !
