Crypto Currencies is facing local law policies many where: Local law can be a barrier for many countries to accelerate the blockchain industry. I read the sentiment of many people where the bitcoin or concurrency is not legally authorized but they are very much excited to use this technology. I think, a global revelation only can bring those countries to be inspired.
I think you should clearly distinguish the two concepts of blockchain technology and cryptocurrency. In my country, the government encourages the development of new technologies, and blockchain technology is no exception. But cryptocurrencies are a different matter altogether, it's banned from use for payment even though you may own them, and there is no clear regulation on cryptocurrencies.
