Moslem countries are going to used bitcoin and others cryptocurrencies and blockchain technology if it can be centralized. Remember that most of the Moslem countries have no democracy and because of this the citizens are not completely free from the governmts. Cryptocurrencies is about freedom and that is what most of the Moslem leaders will not like. Country like Saudi arabia and Iran has king that may not want the system that they don't have control over and that is why they may not want blockchain technology or cryptocurrencies system.
If you are from western countries then there is no wonder that you have this opinion about muslim countries in your mind.But kind ruling countries are not like they are treating us like a slave which can be seen in histotric films,but it is more liberal country then ruled by political party if the kind if much good person,I don't think king is opposing this technology but the media will be portraying something like that.
