What would you do when you're talking to someone but then he suddenly talks about his hatred on Bitcoin, what would you react to it?
I've never actually experienced anything like this before, I just want to be prepared when it happened to me.
I presume that the person who strongly rejected bitcoin has a negative experience from his past with it and so we can not condemn him. This kind of behaviour could be the product of the scammer so meaning he was a victim. If time will come that you can encounter this kind of person I can say that you are the perfect person that he meet in his life. Because you can convince him how bitcoin is really good for investment and show your transaction if you are really serious to convince him.
