I joined the bounty campaign since 2017 and remain active until now. The most difficult times are the end of 2018 and 2019, many bounty campaigns are scam and do not give rewards fairly.
Yes, during Q1 2020 I got several good bounty campaigns, including Tachyon and BestChange, really giving rewards fairly and on time

No. I am 100% working full time as a freelancer, and bounty hunter as one of my main sources of income besides trading.

I have never joined a social media campaign since 2018 because it is less profitable I feel.

Of course, by far the most profitable are the signature campaign and article campaign. It requires in-depth analysis and a willingness to make constructive posts so that they can join potential signature campaigns.
