Hi! No unsold coins. Premine is formed depending on the results of the presale. That is, the main chain will be launched with a fixed premine, which will be completely distributed among investors. Therefore, we set the developer's fee, instead of a fixed share of the premine. The funds received from the presale (as you can see on the website, they are aimed at developing the project) will be used to create a minimal working prototype and develop cryptocurrency, and we are going to get profit when the project is already fully operational.
