I can't believe there's some fucking scumbags here saying it's bad if ISIS use Bitcoin "because it gives Bitcoin a bad image".
ISIS is a slaving, murdering, fascist organisation that literally brutally tortures and executes hundreds of people every other week to instil terror, strapping bombs to young children and imprisoning 9 year old girls as sex slaves because they don't follow their specific religious sect. They are brutal fascist psychopaths, and the only problem for you is it could be bad for Bitcoin's image? Shame on you.
