That's why we need to do something in able to encourage them and put their interest into bitcoin.
LOL, try to supply them items in
BTC.
I will see, how You will be able to change the interest from the profit to
BTC.
All the bills are in local currency, just no one sell fuel in
BTC.
Who will have the currency exchange risks for free?
This can be an option but its also not easy to do and it will also need you to invest in them and I think that is not the point of this.
I think that they have to know how its working and why its profitable.
