I've found that reframing Bitcoin as a rebellion -- against the US dollar being a tool of oppression against the people in this dollarized region of the world -- to work.
Well, I noticed Salvadorean love US, love dollars, love the obsolete American dream that still being in the minds/plans of many (on average 16 people per day still leaving ES to illegally cross borders and reach the US, reach more opportunities).
I'm glad to hear that you tested Bitcoin as a Rebellion and got good results/feedback... congrats! Maybe things are changing, and less Salvadorean will start building on top their own country, literally is like a blank page for anyone living there these days.
