There are a number of people who do not like bitcoin, but the reason is because they do not understand what bitcoin is and what it can do for them. Some think it is for black market scams and such, but this is not the case. They need to learn and be educated!
They cannot like a thing that they do not understand and those people has no valid reason of not liking bitcoin, I think we should just have to understand them because that is really the reality that we cannot please everyone here.
Those kind of people do exist on this world which they usually refuse directly to a thing without even knowing it. If they heared about scam things about bitcoin they would directly turned back from it. You are right we cannot please everyone about on engaging on bitcoin.
