Another option would not be fair for them, they must respect the conditions.
Im asking this because they wrote in the whitepaper, if they dont reach the goal, the project will be canceled and the founds will be refunded to the investors.
Quote from whitepaper:
We have set a minimal goal of 500 ETH for the crowdsale. A project of that scope needs funds, and we believe that it would be unreasonable to dive into such a project without enough funds. Therefore, if the minimal goal is not reached, the Ethereum contract implements a method to refund every investor and cancel the project. This is also the guarantee for you to invest in a project that will live and have enough token supply to reach a comfortable market cap.
That is what a good ICO and project does as a method to encourage people to invest, there is no risk for the investment if things don't turn out well, we all already know that the idea and technology has immense potential, the ones that invested also know this, so the only thing we can do now is not act like fudders, and help the marketing of this token, it will pay off if we keep faith in the technology, so don't despair and have fun.
