Not to take anything away from your efforts but I think your list reflects the fact that there are not really any good bounties anymore. If it was 2017 I could not see myself promoting any of those bounties. If you want to make money in 2020 you need to find some other way.
Everyone is entitled to their opinion but I think there was nothing special about bounties in 2017 except they exist during the period of great pump in the history of cryptocurrency, this gave even the most useless project the opportunity rise in price without any reason and bounty hunters made lots of money,
Nowadays, with the condition of the market, most project are struggling to survive, there is no free money anymore, or a sudden pump that shook the entire world, if this was 2017, most of this project mentioned above will give hunters good money because some of them have better prospect and potential to succeed more.
