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.
Definitely that governments would regulate cryptocurrency if it is being adopted in their country. Almost everything is under the regulation of the government. Taxes, laws, and policies are everywhere that we must obey in a country we are living in. The more the government sees the growth of cryptocurrency population locally, they'll look over it and will eventually try to control and limit people using it. Regardless if they see it as a threat or not, if they know something inappropriate can happen there like illegal transactions, they'll make an action to prevent it.
