no doubt some people will dump them to get whatever coins they can fast, spoiling the price for everyone else of course. I will hold onto my tokens until they redeem an appropriate price.
People dumping their tokens is quite understandable since they want to get their funds back as soon as possible. I however doubt that people will dump the market significantly lower than its main 1:1 value.
If the market gets dumped down significantly at start, it will surely result in whales buying everything up, and from there pump that market to more appropriate levels.
Overall, I am quite satisfied with how things are progressing. We shouldn't forget that it wouldn't take any effort for BTC-E to completely disappear with people's funds. That's why I respect what they do now.
Another thing we must not forget, is that if the government managed to seize everything, the chances for people to see anything back would be very close to 0%.
