We just need to encourage them to use the bitcoin more and more, I'm pretty sure that we can encourage them by motivating them and tell them they can make profit and can accept it easily.
That is very hard bro, you can't just tell them like that, its a business and all business man/woman cares a lot for this business and especially bitcoin price is very volatile. You can't just tell them that if you use bitcoin you can make profit, how come if the price go down like this time. Accepting bitcoin for local that don't know the disadvantages of it can make their business lost.
