Interesting video.
I hope bitcoin digital currency can be in the future, free from government intervention, free of taxes, free of policy and government monopoly, absolutely free ...
I do not think governments can ever regulate bitcoin. I do not think they can regulate banks either.
I don't know about bitcoin itself, but to the extent there is any regulation, you would have to regulate it at the access points. That is, where people turn fiat into btc. That's beginning to happen already, and it's not going to stop.
