There are so many bounty campaign that moderate by newbie with 2/3 activities, is that kind of bounty are safe and believable?
Bounty campaign that moderate by newbie is scam most of the times. But you can participate in the bounties that manages by a group or team. However, if the bounty manager is renowned and the fund is escrow, the guarantee of payment is higher. Above all, there is no guarantee of receiving payment from the bounty.
