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 
Theres a same occasion that i have joined in telegram that the team Freezes the bounty for 6 months to avoid necessary dumping but as expected the price dumps more lolQuote
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.
Theres no locking that must happen,because the successful projects will progress even the hunters dumps all their bounties Quote
Instead of locking, teams should just concentrate on other methods such as buy back and loyalty rewards to lessen the chances of price crash.
And also they must find investors,lure them because of the project goodness and if this not happens so it only means the project is not worthy of trust
