I think you don't to do anything to the people who don't like bitcoin. Just leave them and let them think what they want because soon i believe they will like bitcoin if they see something big on it.
yes that's right, let the guy know by itself about bitcoin and what are the benefits of bitcoin. and I think it would be a waste of time if we think of people who do not like bitcoin. we who believe in bitcoin, better focus more on future developments.
