We are actually in the same boat on this one. I have watched MegaCoins progress for about two weeks and been thinking to invest everyday but btc-e has been holding my withdraws back, apparantly they needed to verify that I'm a legit user (understandable). But because of this (well, kind of because of this), I missed out on the recent super-ROI that occurred. Though I still think that the coin has great potential to reach 10 dollars or so in the near future and I'm probably going to put some funds in megacoin as a long term investment rather than a short-term. But then again this is what I'm doing with most smaller alt coins. All I need is for one to be successful and the others not to drop to 0% value, lol. This market is extremely hard to analyze though. I think megacoin definetely has potential. Bought litecoins at 9$ and watched them go up to 48$, which made me a pretty happy fella. Now I want to see megacoin do the same.
A tips would be to look on to quark coin aswell, I think it's getting a pretty high amount of hype at the moment and investors will probably go in to raise it's value even more.
