Bounty campaigns always follow market developments, so the timing of participation needs to be appropriate. This year I see bounty earnings quite stable, much more so than 2018 and 2019. It looks like a positive sign for future bounty projects.
There are still many scam bounties this year, I don't see the difference between 2020 bounty projects to that of 2019, last year there are many successful bounty projects too, those who are complaining are those who missed out of the promising bounty projects
