"The ISIS economy and its fighters predominantly rely on the production and sale of seized energy assets—Iraq has the fifth-largest proven crude oil reserves in the world. ISIS also depends on the steady income it extracts from private donors, the heavy taxation and extortion it levies on its captive population, the seizure of bank accounts and private assets in the lands it occupies, ransoms from kidnappings and the plundering of antiquities excavated from ancient palaces and archaeological sites." source


ISIS makes money every time they loot a town or attack an oil refinery.  On top of that, they're receiving billions in aid from wealthy gulf states and Saudi princes.

If you actually follow either war (syria, iraq) you'd realize that if you put an ordinary laptop in front of the average fighter, they'd cry 'haram' , shoot you, and burn the laptop to appease their invisible sky god.  You MIGHT convince a regional leader to accept BTC, but I'm willing to bet each one would think you're trying to rip them off.

"funding ISIS" is undoubtedly the funniest attempt to slander BTC since its inception - I don't think any future fearmongering can top this
