Not all the bounty and airdrop are scam, in the means of original, they're most be a counter felt, many bounty and airdrop coin has been dumped and also not distributed by name of scam. Therefore there are good project among the line of campaign.
Good luck...
Agree, some bounty campaigns can make money. Maybe a lot of bounties don't pay or turn out to be a scam project but I think it's unfair if we generalize. Hopefully next year will be a good year for bounty hunters
