And comparing it to Bitcoin's beta is so retarded. Have you not noticed that crypto currencies have gathered a tiny bit more attention from the world since then? It's no coincidence that NXT's rival emunie is following similar development principles.
Which development principles do Nxt and eMunie share?
eMunie is in closed beta while the developer fixes issues. Meanwhile, Nxt rushes to sell coins to the public before it's stable while using the excuse that its still in beta when they have technical problems.
I don't see how the approaches could be more different.
Both closed source to some degree, will be fully open sourced later.
