I have a strong feeling that the referral system is something to look forward to because it is very different from other ICO's because we can get up to 5 levels unlike others it only has one level. This project is like a good virus that spreads all over to different nations to entice them with its great capability. if this project pushes through with a glorious amount of success then this is something worth promoting because you can earn some commission by doing so as well. That is good to keep the token potent.
