Yes, 2018-2019 is a so bad time for bounty hunters and also for investors. There were too many scam ICO projects at that time. I still remember that I ever stopped working bounties for a while because of no earning at all. I am sure you also did the same as me, reducing the number of following bounties or even stopped temporarily. A better era of bounty just started after IEO became trending to replace ICO. Till now, most bounty hunters prefer to join bounties provided by IEO projects.
