I was following the status of so-called next generation coins closely but I had to turn my attention elsewhere over the last few weeks. The last I checked, Nxt was first out of the gate and going pretty strong. XCP was in very early stages but now it's been added to coinmarketcap.com and value has increased about 24x. eMunie seemed to be in a weird place with the canceled IPO. Also various IPO coins were found out to be scams when the authors ran off with the IPO funds.
What's the latest?
NXT is definitely in a very healthy period of it's development and already got such a gigantic community that it is not going anywhere but up.
NXT is soon entering "layman market" and that is where you expect to see the price really skyrocket.
XCP and Proof of Burn is kind of interesting, but they have "burnt" themselves with artificial inflation of the price. It's nowhere near worth 24x it's original IPO price this early on. The interest is nowhere near to justify this price.
Some greedy pump and dumpers have driven the price up a lot and this will most likely lead to a crash and burn. And once you have been labelled as a pump and dump then people and especially serious investors will become weary.
Hopefully they will be able to make something out of it though.
eMu is also a interesting concept, but with all the hiccups and postponing I think it'll enter the scene too late.
