The cryptocurrency has nothing to do with any race or any race. Muslim countries also have elites, and they are more likely to buy bitcoin early on, which is very normal. In the future, when Bitcoin takes off again, the cryptocurrency will win the world.
Any race can accept cryptocurrency even the muslim country as long as they have basic knowledge about it. Also cryptocurrency is for everyone so it mean anyone can accept and adopt it, so there's possibility it muslim can accept Bitcoin to their country. But the only problem is if their government allowed crypto to used in thir country, but for sure once they saw the good side of crypto sure they will accept it.
It will be very dependent on the regulation by a particular Muslim government on the adaptation of cryptocurrency. Some says that other Muslim countries are already adapting it. We can't tell for sure. But as long as it is not against their belief then it won't be a hindrance for them.
