Ill be honest, they are really starting to clamp down hard in the U.S and is making me nervous.
With this exception of this California action, everything else in the US has been completely consistent with existing US law.
I am speaking of the recent developments with the IRS and FinCen along with this as well as the numerous services surrounding bitcoin that have gone down.
As am I. Recent developments with the IRS and FinCEN are entirely consistent with US law as it has existed for years. Ditto Mutum Sigillium seizure warrant. Tax and MSB implications were directly addressed years ago in my State of the Coin 2011 presentation, among others. If you operate outside the law in your jurisdiction, the obvious result occurs... eventually.
Then I must be confused with the state of things then. I was under the impression that the recent IRS (or was it FinCen??) ruling/statement was that mining bitcoins will/may require an MSB/MT licensure.
I could be wrong and hope I am, I am not trolling I truly want to know.
