The fact is its always a bad idea to dump all your tokens you get from bounties unless you promoted a not too good project,
When there are sense of scams closer than it's a good idea to just throw away your bounty rewards, so it doesn't belong to the trashcan.
I've seen few bounty projects that hunters dumped and later the token price surge in value for example Gowithme bounty ,so how many of you dump gowithme token? The token did 10x already
They probably caught up with the hoaxes because certain projects are having issues and it's common trick to lure people to sell so whalers can grab those sold tokens. Also, there are some people that they don't even care with the project but they only need the rewards.
