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.
You are wrong here. Nowadays religion plays less and less of a role in a country's economy. For example, United Arab Emirates, mentioned in the OP, is actually a crypto friendly country. Earlier this year the Dubai Multi Commodities Center (DMCC) gave a gold trading company in Dubai the cryptocurrency trading license after which the company launched the “world’s first” cold storage vault for crypto. UAE even wants to play a leading role in adoption of blockchain technologies

Another example is Malaysia, predominantly Muslim country, which is very crypto friendly, unlike Bolivia, Ecuador and China (PRC), where Bitcoin is banned although they are not Muslim countries.
