I'm very skeptical of NXT, be cautious with that coin. It's still closed source too. Supposedly they are releasing the code on Jan 3, I'll wait till then to decide whether to invest.
Everybody is skeptical when it's not called litecoin or bitcoin. I will not cry if my easy earned fraction of BTC by mining scamcoin at low diff during 72h is wasted. I hope these kind of new gen coins will succeed cause once Asic is released for script in March, we're done.
