The Bounty is managed by a good and trustworthy Hhampuz. But I see that this project, Hhampuz uses the payment of BTC and they also limit the account level and the number of participants. Even with a full member account, I often can't participate because of the full participant.
For me actually, before joining the Bounty project, we have to do a check, even though it is managed by an experienced manager. There are a few steps we have to go through because a fake project can happen to all managers.
