Would be better to buy NEM than NUMUS when I'm looking in the Discussion Thread of NEM. So many posts with ideas, updates etc.
Things there going well.
In all fairness NEM was announced a while ago, around 4 months if I'm not mistaken and it's community is much larger than Numus', but Numus was only announced a week ago. If I had to pick two of the most promising alt-coins for 2014 though these would be my 2 picks.
