If you dont reach the goal till the end of ICO, will you extend the sale and go for the final advertisement push? You came too far to quit so i hope you will bend your rules a little.
They should redestribute the unsold tokens to the existing token holders or they should burn the unsold coins. Either way its good for the exisiting holders
I think everything will be redistributed to the investors in that case.
Another option would not be fair for them, they must respect the conditions.
