US Government making a move on Bitcoin is inevitable. The telegraphing thereof has already begun. Bitcoin has to survive the tribulation if it wants global adoption. If it doesn't survive, it'll fall into obscurity or be marginalized.
Sadly, I belive this too. Bitcoin have to survive this and become accepted by the common man and the governments . Otherwise all you can do with it is buy weed. Iwant to be able to buy a car with my coins someday.
You need to understand that Bitcoin is a game changer. It's a challenge and possibly a threat for to the "status quo" of the most powerful people in the world: the ones controlling monetary supply.
Bitcoin being banned by Governments at some point is a possibility predicted from the very beginning. And that's why Satoshi is a pseudonym and he/they used Tor all the time, working hard to totally conceal his/their real identity. And it's also one of the many reasons why you do not invest in it what you cannot afford to lose.
That said, we should assume clever people is advising government. And banning Bitcoin is bad advice, because it will very likely make it stronger on the long term - because it is designed with that in mind.
It may be most effective to them to regulate it as much as they can, trying to control it, even by owning as much hash rate as possible. And if they finally decide that it's a lethal threat to the current financial system, it may be more effective for their interests to pump and crash the market at will.
But at the end of the day, there is no easy or obvious way to get rid of Bitcoin, unless the whole Internet is taken down.
