There have been a lot of arguments concerning this topic. Again, there have been a lot of pronouncements from governments officials pertaining cryptocurrency control and people actually reacted to them.
Even though some governments may want people to think they control and regulate cryptocurrencies, that is far from the case, as cryptocurrency cannot be regulated or controlled by default. Companies providing solutions related to this new form of money, on the other hand, are subject to existing guidelines which apply to other financial service providers as well. The flow of money in the cryptocurrency world is not controlled by any central authority, nor will it ever be.
What is your own thoughts about this?
