I do not understand the need of another coin here.
If I want to buy a domain I could simply use FIAT and I think it is also possible to buy domains by BTC etc.
Or to put in another words: If we create for each product a coin we would come to PizzaCoins and BurgerCoins.
Since we are building as many things as possible on smart contracts, I think having a NAT is very important.
Other than that we believe, that, once NAT is on the big exchange platforms, it's getting more interesting for domain investors to use us. This way they can make money on NAT in two ways - trading domains, and trading NAT on exchanges.
