3. If the team offering the bounty hunters to pay a small amount for the bounty hunters to process the rewards then pretty sure they are scam. They just trying to scam even the bounty hunters.
You mean they ask bounty hunters to send money to received their rewards?
If yes, this is most likely one of the old tricks, actually I have encountered this before, and yes, the project turn out to be a scam project. First thing to remember for bounty hunters, they should not produce any amount of money just to get their rewards. We should always remember that this is not how bounty campaign works, they are the one who's going to pay and not us.
