it all depends on the allocation given to the bounty hunter and also depends on the price of the token after it is distributed later, if the price of the token is expensive then the benefits are also many, sometimes many bounty hunters are disappointed when the token is distributed there is no demand even left to die.
It also really depends on the number of participants. If the participants are not limited, the rewards will be smaller, right?
So for airdrop, it's better to choose the number of participants is limited, first come first serve, and this airdrop is held by exchange or trusted project. The rest, don't expect too much, most of the airdrops currently have very small rewards, often not reaching the minimum limit for withdrawals.
