Yes. I would hold. They may get dumped a little when they hit an exchange, but with such a low total supply they should fetch a good price.
(I'm mining it myself).
You can only mine 1000 KDC coins per day with 1000Kh/s, so I don't think we will have a dump when we hit the market, total hashrate is now around 110Mh/s, a lot of people (including me) are mining this for the long run. I also had a talk with the PR of KDC how they can prevent a dump at the start, because as a coin owner you also have the responsibility to support your coin on the exchange in the beginning.
