Well, you can't regulate Bitcoin, at least not without regulating one of the last free markets we have left: the Internet.
What governments
can regulate is businesses, especially financial service ones dealing with virtual currency. I agree with what Ron Paul says is government's proper role: enforcing contract rights and preventing fraud.
So, for example, when New York State's Superintendent of Financial Services, Ben Lawsky,
says some regulation of Bitcoin businesses, if done with a light touch, can make sense I'm in no rush to disagree. An example might be procedures to ensure exchanges are not engaging in deception with fractional reserves & Ponzi-like accounting. I think a majority of the community would agree with that. There was also mention of a mandatory disclaimer sites could show warning of risks and no recourse for loss etc.
In other words, simply give the free market helpful tools to do its job effectively, but no more. That makes good sense to me.
