In the Moslem Countries like Saudi Arabia, Qatar, United Arab Emirates even Brunei Darussalam etc were enacted Islamic Economy System based on sharia. Is It Possible that The Moslem Countries can accept the cryptocurrencies system in their economic system? What's your opinion?
Unofficially - yes, but publicly - no, because crypto is all about freedom, and Muslim countries tend to suppress the wish of their people for freedom.
Anyway, the countries you've listed are economically well, so I don't think their citizens are very much interested in cryptocurrencies as they have a good basic source of income provided by the state.
