I wonder how ISIS would respond to this news. Would they consider the startup owner the infidel or Bitcoin as well? Anything that goes against sharia law would be considered a great sin to those devote muslims.
The Startup owner is a guy called Matthew J. Martin, who converted to Islam five years ago. So he will not be considered as an infidel (i.e. provided he has converted to the Sunni sect of Islam). And I don't think that a majority of the Muslims are dependent on Islamic financing. Only the fringe 1% or 2% of the Muslim population is in search of it.
