I vote for Noblecoin, since I like the professional approach from the dev.
There where many opportunities where he proofed that he stands behind this coin and builds a solid base, instead of focusing on a pump with nothing but a hype.
For example there is a marketplace trading several gift cards and the possibility to buy precious metals with the coin in the near future. This requires facing tax regulations for ongoing existence.
He is backed by a community which prefers objective discussions to pure speculation. Hype comments are searched vainly.
Therefore I'd like to point out that this coin is highly undervalued at the moment and you should take a second glance despite it's current price.
