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.

I think most of us that joined bounties in the year 2018 had experiences like that. I was also expecting that it would happen because of the lock-in period but I guess the investors are just for short term and they will sell it after listing because their bonuses are already enough for profit taking. ICO bounties should do buybacks or Eth/btc payment so investors would not get the fear of dumping from bounty hunters.
