If there is another arab spring which produces widespread independence movements in middle eastern nations, it is possible existing banking systems could be overthrown as people embraced crypto currencies in an attempt to find alternative ways of doing things.
To a degree, middle eastern nations appear to be run by mullahs and religious clerics. I don't know if there is anyone with authority in the middle eastern world who would be pro bitcoin, that other arabs or muslims would listen to.
Middle eastern leaders tend to repress education and information on topics like crypto currencies. If there was a bitcoin following in the middle east it would likely be a small demographic.
Your posted question is bit sensitive to answer boldly, but, lets try to be liberal on the issue, lets not generalized but instead an objective opinion would be more safe.
The entry of crypto currency into the market does not indicate that a selected business investor are only accepted in this digital transaction, with emphasis on Christian or none Christian, the Eastern community wither they like or not, would be affected by the growing numbers of investors coming in into the Crypto currency Digital Transaction, in fact there some business financial community are looking into the Digital Transaction on Crypto in Dubai, United Arab Emirates, but no specific result yet. Let just hope that they will look into what benefits they can have from Crypto Currency market trading.
