Recently there were some news regarding Bitcoin regulation. I'm not sure how the heck government would regulate Bitcoin? In order to regulate Bitcoin government have to shut down the whole internet or try 51% attack which is currently impossible. There is no way to to tax Bitcoin while transferring it. Yes of course government can regulate centralize exchange but Bitcoin doesn't need centralize exchange to transfer it from one account to another. Either the government doesn't understand Blockchain technology or they are simply mad. Government can of course declare illegal to hold bitcoin, but how the heck they identify which bitcoin address belongs to whom? If government want to arrest it's founder Satoshi Nakamoto, best of luck with that.
Bitcoin power with Blockchain technology is unstoppable and cannot be regulated. There is possibility that Blockchain technology will actually regulate the regulators in coming future it would be interesting.
