Somehow, project are to be blame for given immediately the token to bounty hunters. If they avoid massive dumping their they should lock the token by certain range of time. But I doubt its only the hunters that contribute the decrease of price. A good example is a project Elysian! They don't distribute the token to the bounty hunters until now and planning to distribute it by October end. But look at the price after the ICO ended it was decreased to almost 70% from the ICO price. This is a good example that not just the bounty hunters are to be blame when price decrease.
