I see that you have newly added bounty campaign - WhalesHeaven, but they don´t have any announcement thread on this forum. Further, I see a problem that they do not have any information about their token on the website. Also, we can´t see the platform without registration to check the volume, so I would be very careful with this campaign, at first look looks good, but there are some missing pieces of information that are needed.
One of the best things is that they guarantee weekly payments. If they really keep their promises then I don't think that's a problem. After that, a monthly payment is made. If it's legit, 52 weeks is not a problem. Instant payment guarantees, tradable rewards, are good opportunities and are sure to be the target of bounty hunters. Moreover, many campaigns give false hopes, such as distribution delays, locked rewards, etc.
