I guess it does not need to be encouraged. for people using bitcoin, or for those who know to use bitcoin, they will accept it at local businesses they create. using bitcoin emblem in the business they do, will give a signal for bitcoin users to be able to know that local businesses that accept bitcoin
That is true, but the thing is if why a local business would adopt bitcoin if they does not even know that there are any bitcoin users around them to use bitcoin in their services? So a local business would only get encouraged if they see some people using or having bitcoins around them so that they can come to know they will have some basic customers around them.
It is a risk that those business owners will not going to take. Even how good the market of bitcoin worldwide and how its price is being good and stable landing at $800 but if that person is just owning a small store that is just hoping to have some good customers by simply paying him cash will satisfy him. And he won't even bother and waste his time for knowing who are those bitcoin users around him.
