Based upon the whitepaper, I can say that this project can run 10 days ICO because I saw in the roadmap that Xbrick Exchange Project was already started 2 years from now. Since 2016, the team had planned to make an exchange that is secure and efficient in the world of cryptocurrency. As of now, they will launch the public sale for the project. In short, this project is nearly to success. Assume that 10 day run is enough for a project like this.
A project's success depends upon its goals, if the goals of the project is SMART and if they have a concrete plan on how to achieve it. If they are able to lay out a plan or a roadmap and during the duration of the projects development you see that they are able to follow those plans without delay or problems, that would mean that the team is able to go through their plans and execute them, that they are really capable in realizing the project they are developing.
Are you a teacher? Yeah! I believe that a project needs to have SMART in order for it to success.
S - Specific
M - Measurable
A - Attainable
R - Result Oriented
T - Time bound
Isn't it? Well, Xbrick should have these key features in order for the project to hit their objectives.
Roadmap is just like as a lesson plan of a teacher, it should be executed.
