if someone told me that it's bad or something negative, i would say that if it's that bad, then i guess it wont be famous and the value of the bitcoin just drops down to 0. also, we cant really convince the person that doesn't like what we do if that's how he looks at bitcoins. we could just hope and give them some advice if they change their mind.
If they think of it that way and they know we're consistent with bitcoin, then the best thing to do is continue to show evidence that bitcoin is a good business by showing some of the results we have, they will change on their own.
we do not have to force anything on someone who does not want to open minds to bitcoin.
I am also against making people to do something that they are not willing to so the only option that we have in our hands is to politely tell them about all the benefits and give them a demonstration.
However, if we show them our earnings and things that we bought from it, that would be more effective. After all, actions speak louder than words.
