Inasmuch as I wouldn't want to get involved in a sensitive discussion such as you have brought, I don't really know how the entire Arab people dumping Bitcoin will lead to price rise. Beside, do we really need people to sell their Bitcoin or we want more people to get involved? I am really seeing some contradictions that need clarification in this posts.
I see the OP as a person that thought he did not invest when the price of bitcoin was low and still which to invest at a lower pricem. That kind if thinking can make someone to think like him. There are some Arab nations that ban bitcoin but I think most of the Arab countries accepted bitcoin. What I noticed they do not accept is gambling. Probably some of the Arab nations might see link between bitcoin and gambling in the last, but of which they are wrong.
