I think US is really overreaching on this one.
Putting tighter regulations on ICO's
AlphaBay and Hansa was taken down
Bitmixer.io officially shutdown its business (Because of pressure from the gov't?)
BTC-e then taking down by Fed
Who is next then on the list of the Feds?
I don't know why the US government is suddenly taking on the crypto in general. This is out of their jurisdiction. I would understand if they will bully another third world nation, but this is Russia that are involved here. I think they should have think many times before seizing the BTC-e servers and now BTC-e is trying to get back the funds to give it back to its customers. US has crossed some boundaries here and for sure there will be repercussions on this. And this actions is not the best and most effective way to handle it. They are now waging war on crypto world for that matter. But why just now?
One thing to keep in mind, the US government is run by the big corporations, has been for several years now. So when you are trying to summarize the situation, it's good to work out who benefits most from the events you described.
