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.
