So, what will happen to the unsold tokens, will they be burned or frozen for some time period?
Burned, but lets hope this doesnt happen

We want everyone to get the same value so we dont have any Pre Investors/ico just one simple ICO. We made a huge cost already with having lawyers and we
are taking a risk with this, but we believe this will be great longterm and the most fair option.
It's a good thing to burn the unsold tokens if there will be any to ensure the transparency. I hope this situation doesn't arrive.
