It's an alternative coin to bitcoin. Most alts are basically almost the same as bitcoin, but have a different name and logo and different total numbers of coins. Nascoin is not based on bitcoin, but on Nxt, which has a completely different code base to bitcoin. Nascoin's dev disappeared and the coin has crashed heavily in value since, leaving a lot of angry investors who feel they have been ripped off. It might be a good idea to choose a new name for your asset.
Not worried about the name, the concept is the coin gains its value from the existing community's adoption. The current inefficiency already present in the existing network seems to provide a conduit for a natural power vacuum.
For example I see many different poker related coins or sites, but never one proposed by the players for the players, in order to link the entire industry together.

The idea is for players to create and adopt a universal digital poker coin creating a near zero (or zero) cost network for instantaneous bankroll and exchange (ie “money” for chips) transactions. By creating “network liquidity” the players are able to put pressure on sites to offer a rake standard of superior quality.
