So there's this campaign that I've participated that locked bounty rewards in the hopes of avoiding token dumping. As what I expected, the dumping still happened. What's even funnier is that it is now the bounty hunters who complains unlike before where investors blame bounty hunters 
If there's any coins or tokens that should be locked, it should only be the team's share (or maybe add those given to advisors). Both parties (investors & hunters) have invested either money or time to get their share and they should not be subjected to such restriction.
Instead of locking, teams should just concentrate on other methods such as buy back and loyalty rewards to lessen the chances of price crash.

If the dump still occurred when the token for hunters locked, then the dump is not caused by hunters.
The team must do something about their token, so the damage of the price can be recovered later.
There are too many ICO ended with token price crashed to the ground.
