Expect more incoming investors on this project as they fixed some problems during the start of the crowdsale.
Many people also bought early for the bonuses. Now the 20% bonus is ending if I recall. And as this is an ICO, it is not impossible to reach 5M in a week.
Still, chances for there people who want to purchase HKNS token because there are 9 more hours left for 20% Bonus. Even a small investor can participate in this Hacken ICO where they are giving chance to small investors also.
