I'm being devil's advocate here, what if you haven't raised your ICO targets, are you still going to develop at least your alpha version? We know very well that alpha version is not really ready to use. Sorry, but I'm not confident with your project. But then, you can prove me otherwise.
We will release the alpha application in any case, but the creation time will be shifted, and this will be indicated on the roadmap.
If the exchange does not let us in or the ICO is not successful, then we will reconsider our ideas and make the sale of tokens through the site, re-do the roadmap and move the time frame.
