i don't think that we can help them, they have to decide on their own
Yes we can, we can encourage them. We can explain them what are the benefits, like those related to taxes or that they will maybe easier find bitcoin investors then fiat investors or that with using bitcoins they could be more competitive. There are risks too, ofw course, but it's worth trying.
Suggesting is the only thing we can do in that case, because a local business would only start accepting bitcoins if they see any progress of bitcoin around them, and for that they should know at least a few people around which are interested in using or spending bitcoins so that they can add bitcoin to their payment systems, otherwise they wont look it as a good idea.
