I think users need to accept first the bitcoin. Because if the users not know the Bitcoin how do local businesses accept it.,
Yes users should need to accept it first and that is included the way you are going to encourage those businessmen to make themselves users of bitcoin. But you really need to convince them that bitcoin is a great crypto currency and it will be good if they are going to start using it. When it is already clear to them that bitcoin will make their business great, they will start to like it.
It's hard to convince someone if he does not want to listen to you. And to persuade businessmen to convince is even more difficult, because they risk their capital.
It is best to invite them to a training seminar. And give them information about the advantages of bitcoin
Well that's an easy thing if that guy doesn't want to listen to you then just show them the proof that bitcoin is real, show him that you can convert it to cash and for sure that guy will go crazily in love with bitcoin. Because he is a businessman, what is circling on his mind is only money. But if that happens then it's up to you if you want to keep introducing it to him.
