Seems to me that in the short term, as long as cryptocurrencies keep getting used to move money out of non-western countries (India and China amongst others), into western countries, there is no reason why western governments would want to hinder such activity. At the same time I wouldn't be surprised if China and India try to ban them, although with all the rampant corruption at all levels of government, that might prove very hard to enforce for both of them. With regards to Russia, I don't know what to think.

Am I wrong in thinking this?
