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.
Businesses owners prefer to stay out of trouble, if you begin to say to them they can avoid taxes with bitcoin they are going to avoid bitcoin even more since they prefer to pay their taxes than to risk their investment in their business.
