Have you heard of ICOs with multiple rounds? Like they raise a certain amount of money now, use that money for primary aims and goals, and then a few months/years down the line (as part of their original plan) launch a second round to fund additional goals and further project development?
It's normal thing in ICO since in every round, the price becomes morr expensive which make since and beneficial for thr earlier investors. The only cautious in this system is when the stated period per round were adjusted and moved. It happens many time when the project doesn't meet the expectation and preparation they expect to the investors.
The team has an option on what to do based on their strategy while still selling the project, all they want is just to raise as much as they can so they will have a decent amount to develop the project, I think the more crucial part is after the ICO as that's the stage where we will know if they deliver or not.
