What will happen to the unsold coins after the ico?
tokens that are unsold in the ico will destined to be burned. by doing this, the team want to preserve the price of every DAN token. for more details, visit the site,
https://daneel.io and scroll down to see more details.

This could even mean that investors who are buying DAN tokens now would even benefit if the hard cap would not be reached and then the Daneel team would deliver a successful project. The lesser investors, the higher their returns. That's another good reason to buy DAN tokens IMHO.
