This situation is rather complicated when governments will still advocate banning cryptocurrencies in their countries, but at the same time adapting the blockchain to their state systems.
I dont think that is possible because once a government stance is developed they are not going to change it. Moreover if they are not pro-crypto they are probably looking to keep the ledgers of all transactions private. This is always a problem with governments be it any other part of the world or specifically Northeast Asia.
I have been watching some new exchanges that came up there with trade mining as their new buzzword like Fcoin and nexybit. Both of them sold away their companies and turned their back to investors who came in to join the trade mining dividends - scammed off their entire investment. Hence the chance of government support is also very low in such projects.
It is a gradual process, there is nobody that is not flexible to changes, even the government also. Look at Facebook, who would have ever imagine that they could turn around and start supporting cryptocurrency.
Let us also take a look at china, prior to the last new I heard of them, the news that was all over the internet then was that they would ban cryptocurrency miners, in which a date was even picked for it, but suddenly, there was silence over it and the last news I heard of them was that they are planning on creating their own cryptocurrency. Bitcoin has gone to deep fir any government to fight it real hard, and the best they can just do right now is to look for a way to take control of it which some countries are already doing so .
