Stop freaking out. You're all good! If you have funds on BTC-e (or will have funds on the new site), just be very careful about not sending those coins directly back to a licensed exchange like Coinbase. Those coins could be subject to civil asset forfeiture. Get some clean coins through another exchange/service first.
I think you would find there would quickly be a class actions against the seizure if people started reporting they were getting raided.
Most BTC-e customers are not from the US.
i doubt it, since such class actions would fail. forfeiture law is such that the standards for seizure are very low, no criminal conviction or even charges are required, and the burden of proof is on the defendant. since the coins would have been sent by btc-e, the customer has no way to prove their origin.
this is just about coinbase customers; it doesn't matter where btc-e customers are based. coinbase is licensed in the US, and they are subject to US laws, including judicial orders regarding civil asset forfeiture.
if anything is clear from the past 15-20 years watching law enforcement in the USA, it's that there is no way to stop civil asset forfeiture. you can only prevent it by properly hiding your assets. (in other words, i agree----do not send any coins linked to btc-e to places like bitstamp or coinbase)
