Given the events in Afghanistan over the last week, it is a great example of where bitcoin could have been of great use to the people of the country. The currency, the Afghani, fell to record lows. Anyone who owned bitcoin was protected and could escape the country with their assets, not worrying about capital controls or confiscation at the border.
Not a good idea though. If people see the Taliban use it it will give bitcoin a bad name that we can't really recover from as long as it's used there.
