So what I am hoping is that enough has been mined at this point to provide some incentive not to dump. As one of the test net miners I was granted 5k, however, at this point I have now mined well over 5k more so I am a bit more vested. The network has been running at around 400 difficulty so I am guessing a lot of people have some incentive to not insta dump, vs coins which get on an exchange in a day and then its a grab for quick value. On the other hand, some people may seek to quickly recover a longer period of mining costs, which could lead to selling.
I am interested to see if difficulty rises now that we are listed. If difficulty rises within the next week one would probably be foolish to dump off the bat as a rising difficulty typically indicates a rising price in alt coins (its not a perfect indicator but nothing is).
That being said, i understand some people will sell a portion quickly to cover mining fees and others would not be wrong to sell if there is a quick spike in price over the next week or two.
