I think the tittle be rightfully written in Central Bank of Kazakhstan, it looks to me that the government is not the one planning on prohibiting trading and mining. The CEO of national bank can only propose any legislation to the lawmakers and not the other way around. Can we expect a good statements from this bankers, not without biases. Not until the law is passed and signed this is not finalised.
Nazarbayev is a very authoritarian ruler. Therefore, you can rest assured that the bankers voiced Nazarbayev's thoughts in their own words. Most Muslim countries have a negative attitude towards cryptocurrencies. Kazakhstan is not an exception to the rules. Every nation has a ruler that it deserves. Cryptocurrencies give advantage only to free people.
You are absolutely right. Kazakhstan is a totalitarian state with one ruler for 25 years and the Central Bank give publicity to the position of President Nazarbaev, because it have no right to make any decisions by itself.
