This chart shows the price of coffee for the past 5 years.
El Salvador is one of the top 20 coffee producing countries with more than 100,000,000 pounds of coffee beans exported each year.
This countey suffered from weak currency and moved to rely on the us dollar.
Many moved to the us to send back usd to their families in El Salvador.
With the brave move to use Bitcoin, thus country might find itself booming ( like btw states and counties that leglised canabis).
This might influence on the price of coffee as well.
Just a thought, time will tell ;)
