What will do you do when ICO end?
I don't know what you mean or want to know.. But you should know that the project is going to continue development even after the ico end... The ico funds will be utilised to develop the project.
And of course they will come on exchanges and you could still buy there but not for the same price and not with any bonus at all.
Speaking of exchanges ... Did they already announce some exchanges that will list the tokens after the ICO?
