I don't believe the US will confiscate bitcoins from anyone who hasn't committed any illegal act as that would be illegal on their part.
LOL.. They absolutely will.
All of us who had coins on BTC-e will not see ANYTHING for years. If at all..
..I always like BTC-e. Seemed a no-nonsense site.. It was actually my FIRST.. I'll miss it.
I had moved my BTC out of the exchange in readiness for Aug 1st.. so Only had a few Litecoins on there. Enough to hurt, but not to cry.
OP - Sorry for your loss. That's a cry amount...
