I know for a fact that some of my friends who actually lives in those countries that they own crypto currency one way or another. I think there ia a link to the comments here that some countries have accepted crypto currency in their respective countries. But I'm surprised that there is a question such as this. I mean is crypto currency against the teachings of Islam?
Islamic religion has never in any way kicked against the idea of blockchain technology as well as cryptocurrency and indeed the countries within this perspective, are really embracing it pretty fast I must say. I really have not heard of single teachings of Islam that goes against cryptocurrency and if it is that, then, we would not have seen some of the Arabian countries, embracing the technology and seeing it as a welcome development in the long run.
