If they could they probably would have already.....and why the US gov't? This technology belongs to the world and we must learn to respect it for what it is not what crooks do with it!
This forum allows, hell, condones total scams. 99% of the content on this site is offensive to humanity.
Why the U.S. gov? Because thats the sort of thing they do. Its kind of difficult to seize a server from yourself though..... Doesn't seem to stop bitfinex, nicehash and the myriad of other false flag hacks which robbed innocent people.
