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.
If a government has chosen to stop its citizens from the use of cryptocurrency, then there is nothing you can do about it. But in such countries there are still people that are making use of cryptocurrency underground, they still have a source that they can follow to buy and sell cryptocurrencies without being caught by the government (if eventually they are caught, they get to serve punishment for it).
Some of the government that has stopped their citizens from using cryptocurrencies have plans to create a cryptocurrency of their own. Just like China did, and then announced that they are releasing their own cryptocurrency. But I read a news article that they are now allowing people to mine Cryptocurrency (I don't know if that includes using it as well lol), and I also saw a post about that in this forum.
