They really thought for something great in this project. For doing something great there is need of some more time. I like the idea of the team members. I know with that many more people will come to be the part of the project.
if some more tasks came to fulfill and that require some time then it is good to give some time as in the past I saw many projects which not gave time to their ICO and they rush for the sale without much publicity and they got nothing.
