IMO Nxt is the only 'coin' worth investing money (not talking about IPOs) in at the moment.
I thought that a while back and was almost 'all in' with NXT but now I have a few doubts. Firstly I agree that it is the only innovative thing to happen in Crypto for a while. But I worry other clones could steal its thunder like NEM or NXTL. I personally don;t care about how it was distributed but I have to accept people do care and have damaged the image of the coin.
I would argue you got to be open to other completely new coded coins like EXO and Qora. Plus the future plans of Etherium and eMunie. NXT was exciting cause it broke away from Bitcoin and tried to solve its issues. We got to be open to other similar innovations that come along. I would only have 30% invested in NXT personally, if NEM is a run away success expect the price of NXT to take a dive.
