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.
That is an unfair stuff to do, even the bounty participant has the right to sell their coins after their hard work promoting the project, but they should also need to be able to consider the time when they sell the reward coins that they getIf 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).
