I think token should be partially distributed. First tokens receive investors and those who have invested their own funds in the development of the project. As soon as the price stabiliziruemost to give awards to the bounty hunters. In the future, project organizers can redeem some part of coins from bounty hunters. And the rest coin to leave in free trade. Then the drop in the price of the coin will be minimal.
These are too perfect conditions and only some of them are true.
1. Token distribution: you can try to limit the distribution of tokens to the project team and bounty hunters (although their share is very small). But this does not guarantee that one of the investors will not become MM and will not manage the token market;
2. Product/idea: to keep the interest in the project after the ICO/IEO, you need a really popular or revolutionary product. It can be a blockchain smartphone, a blockchain with a million transactions per second, an application in the IoT (I do not specifically name the projects);
3. Community support and advertising.
And such as we understand can provide only a few projects.
