There's nothing we can do if the people you used to talked to about bitcoin were refused your words and choose to not believe in you. Don't laugh at them, instead let your success make a noise for you. You know at yourself of what have been lose at them since they refused to listen to you. So let them be of what they wanted to believe at. I believe that someday they're going to return to you asking your help to teach them how to work on bitcoin.
