So do you want to receive a token from a failed ICO project? What will you do with those tokens that have no value? We should be realistic, we cannot expect all the participating projects to be successful
If the project fails, obviously they won't distribute the token. If they do, I'd rather not accept it if I have an option to do so. I don't want to keep another worthless coin in my wallet. But if they reached their soft cap, and they don't distribute their token, then that's an another story.
For participants of the Bounty company there is no particular choice. They either get rewarded or not, and in this game they can get almost nothing for their work. But for everyone, hope dies last, and therefore it is better to believe in the project and in their team, and keep the coins for long-term storage.
