As I see this, NLG not showing the same uptrend at the moment is a very good sign, especially for future investors.
If you search for a long term investment coin, which one would you trust more:
The one which has nearly the identical chart like bitcoin with high volatility with often no apparent reason or the one which keeps at a constant value while no big news are available?

Keep in mind that if an asset reacts intensely to good news it will most likely do so for bad news too. I myself am content with NLG not being the same rollercoaster on the markets as most other coins.
