I would rather suggest joining Social Media like Twitter, Facebook and Instagram. At this time many bounty project more favor the allocation on social media than the signature. The task is also quite easy to do.
The people here seems like have a little interest to invest in new project or in an ICO. Most of them just choose an investing on the coin who has been listed on several exchange because it will make him comportable to thinking that his money will safe. You may know how many project scam has been popping up since 2018 ago and many people who has trapped with this project until he got nothing and never got his money back. I was assuming that this problem which makes social media still feasible to choose as a promoting place because there are many new people who will see the project which is being promoted.
