If I'm not mistaken, the Official Launch of the coin is the first week of January, so in the meantime, this is a great opportunity to get your hands on whatever portion you can afford or feel willing to risk. The client is still beta, but if you view the forum posts, the dev(s) have been very prompt in fixing issues, but still has a ways to go. For me, it was worth the risk, so I bought some coins and will be patient and see where it stands in a couple of months. My hopes are high though
If you have already bought and want this to succeed, the best way to help is to spread the word. Post on facebook, twitter etc... or perhaps, like the video I created a couple of days ago on YouTube http://www.youtube.com/watch?v=f8dLMoZLMzM (It's not great, but it's something to start)
